Pollution will make the environment dirty and harmful to live in. For example:
- Pollution such as litter pollutes the land and water, causing it to be unpleasent to look at, give off a bad smell and attract pestsand diesease-causing organisms.
-Pollution caused by chemicals such as pesticides,insecticides and weedkillers. The chemicals may be washed into water bobies such as rivers which kills aquatic orgamisms, poisen the water, making it unfit for human use.
-CFCs used in some refrigerators makes the ozone layer thinner. The ozone layer protects the earth from harmful UV rays. Without it, the rays can cause skin cancer and other problems.
2. The living things affected by pollution will receive various problems and dieseases such as:
-sunburn
-eye diesease
-skin cancer
-eye irritation
-lung cancer
-reduces clean water for drinking
-causes air difficult to breathe in

2.The living things living in the trees will lose their habitats, turning homeless. On top of that, many species of animals and plants may become extinct.
3.Humans can carry out reforestation to restore the forests and the wildlife that lives there.]]> 2019-07-17 09:00:09 UTC https://padlet.com/Imelda/humansimpact/wish/371426883 Song Ze https://padlet.com/Imelda/humansimpact/wish/371427675 1.Depletion of natural resources will result in the following:
-When resources such as fossil fuels, metals, minerals and precious jewels are depleted, tey will take a long time or cannot be replaced.
-If trees in forests are cut down faster than they can grow, forests can get depleted, reducing the amount and size of the forests.-
-When humans overfish, it cause the depletion of fishes. If overfishing continues, fishes may become endangered or extinct.
2.The living things on earth wil not be able to survive without the natural resources and habitats,
3.Humans can conserve natural resources by practising the 3Rs-reducing, reusing and recycling.]]> 2019-07-17 09:12:18 UTC https://padlet.com/Imelda/humansimpact/wish/371427675 Nabilah https://padlet.com/Imelda/humansimpact/wish/371431079 1.Global warming has a number of effects from a more hotter atmosphere to rising water levels. Global warming can also effect the weather, causing drought in other places or causing a change in rainfall patterns in other places.
2.The living things may not not have enough water to drink (due to a drought) or a flood may result from excessive rainfall. The living things in the arctic might also suffer. A more hotter atmosphere would cause the ice there to melt and lesser fish to live there as there is lesser oxygen in the hot water compared to other colder regions. Global warming may also cause islands to be submerged in water due to the rise of water levels.
3.Humans can plant trees to reduce the amount of carbon dioxide in the atmosphere. ]]> 2019-07-17 09:43:31 UTC https://padlet.com/Imelda/humansimpact/wish/371431079 Nabilah https://padlet.com/Imelda/humansimpact/wish/371431642 1.When trees are cut down, they release the carbon dioxide stored in them. More carbon dioxide in the atmosphere = global warming.
There would also be soil erosion where dirt is washed away as there are no roots to hold them in place.
2.Over 80% of the animals on earth live in forests. As more trees are cut down, most of them would lose their habitat and eventually go extinct as they are not able to cope with the new environment and there would be a shortage of food.
3.Humans can carry out reforestation efforts to help replace the trees cut down.]]> 2019-07-17 09:53:16 UTC https://padlet.com/Imelda/humansimpact/wish/371431642 Nabilah https://padlet.com/Imelda/humansimpact/wish/371432400 1.There are many examples of how the depletion of natural resources affect our environment:
-->Fish from the sea is one of our main food sources. If The fish in the sea are  not able to reproduce fast enough to replace the ones we catch, it may lead to a decrease in the population of fish and its predators.
2.The living things there might have lesser food to eat or lose their habitats.

The environment would be very dirty and smelly causing it to be very harmful for the animals living there.                                                       2. Land pollution- Land pollution caused by mining, farming and factories can allow harmful chemicals to enter into the soil. These chemicals can cause animals and plants to die, disrupting the food chain. Landfills release a green house methane, which may lead to global warming.                                  Water pollution- Water pollution is when waste/chemicals or other particles cause a body of water such as lakes or rivers to become harmful to the animals who live in the water body and drink from it. Water pollution can disrupt and negatively impact the water cycle.                           Air pollution-  When the organisms breathes in smog (which is made out of particles and other gases), it can cause respiratory problems and damage the lungs. Toxic environments are created with hard breathing adaptability. Furthermore, pollutants such as carbon monoxide can also lead to huge respiratory issues on animals.
Noise pollution- Loud noises are known to scare of certain endangered animals and can damage human's physiocological damage and cause hypertension and high stress  levels.
         3. Humans can practice the 3Rs. We can use reusable bags instead of plastic bags at the supermarket. We can take public transport instead of private cars. Throw rubbish into the dustbin and not wherever we like]]> 2019-07-17 10:09:53 UTC https://padlet.com/Imelda/humansimpact/wish/371432638 Hafiz https://padlet.com/Imelda/humansimpact/wish/371434056 1. Humans and animals face new challenges including
> More frequent and intense drought, heat waves and storms
> Rising sea levels
>Melting glaciers
> Warming oceans
2.Changes in the nature of global rainfall, evaporation, snow, steam flow and other factors that affect water supply and quality. Specific impacts include that warmer water temperatures affect the water quality and accelerate water pollution.
All that can directly or indirectly affect people livelihoods and animals habitats.
3. Reduce air pollution by
> Using public transports instead of private cars
> Using LED light bulbs which is more environmentally friendly and cheaper in the long run (Do not be mistaken, this is not an advertisement!)
> Take shorter showers. (This is because it takes a lot of energy to pump and heat up the water if you take a long bath which contributes to carbon pollution)]]> 2019-07-17 10:38:26 UTC https://padlet.com/Imelda/humansimpact/wish/371434056 Chew Yi Jun https://padlet.com/Imelda/humansimpact/wish/371434404 1. Deforestation may cause global warming as when the trees are cut down, the carbon dioxide they store will be released into the air. The carbon dioxide will trap heat and cause the temperature to rise. Deforestation may also cause soil erosion. Tree roots anchor the soil so without trees, their roots cannot hold onto the soil and the soil will be free to wash or blow away.
2. The living animals living there will lose their habitat.This also causes many species to go extinct.
3. Humans can:
- carry out reforestation
-practice the 5rs: reduce, reuse, recycle, repurpose and refuse (newly added)]]> 2019-07-17 10:44:46 UTC https://padlet.com/Imelda/humansimpact/wish/371434404 Hafiz https://padlet.com/Imelda/humansimpact/wish/371435770 1. Deforestation is clearing of large amounts of trees which contributes to global warming. The deforestation of trees not only lesssns the amount of carbon stored, it also releases carbon dioxide into the air. This is because when the tree dies, it releases the stored carbon.
 2. 70% of Earth's land animals and plants live in forests and many cannot survive the effects of deforestation which destroys their homes.
3. >Plant trees
> Use 2 sides of a piece of paper
> Practice the 3Rs ]]> 2019-07-17 10:55:53 UTC https://padlet.com/Imelda/humansimpact/wish/371435770 Tessa Ng https://padlet.com/Imelda/humansimpact/wish/371437043 1. Deforestation causes the carbon in the trees to go into the air again, and this causes more carbon dioxide in our atmosphere. Since carbon dioxide is a greenhouse gas , deforestation causes global warming. Tropical deforestation is responsible for about 20% of world greenhouse gas emissions. 
2 Deforestation affects wild animals, plants and humans in at least four distinct ways: via soil erosion, which can lead to clogged waterways and other problems; via water cycle disruption, which can lead to desertification and habitat loss; via greenhouse gas emissions, which contribute to global climate change; and via biodiversity losses, which can lead to extinctions and loss of natural beauty. 
3.   we can do it by reducing carbon dioxide emissions, waste, consumption of natural resources, creating a retreat for wildlife or any other way, it can be defined as sustainable. For, an example is recycling which is an important part of sustainable development. Households and industrial facilities cannot recycle if there is no separated waste collection .

Global warming also occur when trees are cut down, more carbon dioxide will be released to the Earth's atmosphere. With too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes Earth to warm up, leading to what we call 'global warming'.
2. Animals are changing migration patterns to avoid global warming. Plants are changing the dates of activity such as trees budding their leaves earlier in the spring and dropping them later in the fall. Some plants may either wither or die from lack of water. For us humans, we may die from dehydration and the heat as the temperature rises or may even feel very thirsty frequently. 
3. Everyone can play a part by starting with maybe powering our homes with renewable energy. We can also reduce water waste like taking short showers instead of long showers and turn off the tap when not in use. ]]> 2019-07-17 12:10:39 UTC https://padlet.com/Imelda/humansimpact/wish/371440844 BeRnICe Wu https://padlet.com/Imelda/humansimpact/wish/371446040 1.the environment would be hurt. For example , water pollution. When we dump harmful substances into the ocean such as plastic, oil or even soil. 
2.continuing with water pollution, the organisms living there will eat the plastic and will die . The oil can pollute the water and cause any living organisms to die as well. Soil can prevent most sunlight from entering the water. The plants cannot go through photosynthesis and will eventually have not enough food and will die.

The number one problem caused by deforestation is the impact on the global carbon cycle. Gas molecules that absorb thermal infrared radiation are called greenhouse gases If greenhouse gases are in large enough quantity, they can force climate change. While oxygen (O2) is the second most abundant gas in our atmosphere, it does not absorb thermal infrared radiation, as greenhouse gases do. Carbon dioxide (CO2) is the most prevalent greenhouse gas. Carbon Dioxide accounts for about 82.2 percent of all U.S. greenhouse gas. The deforestation of trees not only lessens the amount of carbon stored, it also releases carbon dioxide into the air. This is because when trees die, they release the stored carbon.deforestation releases nearly a billion tons of carbon into the atmosphere per year. Deforestation is the second largest human-caused source of carbon dioxide to the atmosphere (after fossil fuel combustion), ranging between 6 percent and 17 percent, according to a study published in 2009 in Nature. Carbon isn't the only greenhouse gas that is affected by deforestation. Water vapour is also considered a greenhouse gas. The impact of deforestation on the exchange of water vapor and carbon dioxide between the atmosphere and the terrestrial land surface is the biggest concern with regard to the climate system.  Changes in their atmospheric concentration will have a direct effect on the climate.

OTHER EFFECTS OF DEFORESTATION:


Loss of species: Seventy percent of the world's plants and animals live in forests and are losing their habitats to deforestation, according to National Geographic. Loss of habitat can lead to species extinction. It also has negative consequences for medicinal research and local populations that rely on the animals and plants in the forests for hunting and medicine.


Water cycle: Trees are important to the water cycle. They absorb rain fall and produce water vapor that is released into the atmosphere. Trees also lessen the pollution in water, according to the North Carolina State University, by stopping polluted runoff. In the Amazon, more than half the water in the ecosystem is held within the plants, according to the National Geographic Society. 


Soil erosion: Tree roots anchor the soil. Without trees, the soil is free to wash or blow away, which can lead to vegetation growth problems. Scientists estimate that a third of the world's arable land has been lost to deforestation since 1960. After a clear cutting, cash crops like coffee, soy and palm oil are planted. Planting these types of trees can cause further soil erosion because their roots cannot hold onto the soil.


Life quality: Soil erosion can also lead to silt entering the lakes, streams and other water sources. This can decrease local water quality and contribute to poor health in populations in the area.


2: Soil Erosion and Loss of Habitats will cause plants and animals living in forests to die as soil erosion can lead to soil falling into animals water sources, disallowing them to have a clean water source to drink from. Loss of habitat will also cause plants and animals to die as they no longer have a place to hunt for prey, protection from thunderstorms etc.

3.   Reforestation would facilitate:
  • Restoring the ecosystem services provided by forests including carbon storage, water cycling and wildlife habitat
  • Reducing the buildup of carbon dioxide in the atmosphere
  • Rebuilding wildlife habitats

However, reforestation won't completely fix the damage. For example,forests cannot sequester all of the carbon dioxide humans are emitting to the atmosphere through the burning of fossil fuels and a reduction in fossil fuel emissions. It is still necessary to avoid buildup in the atmosphere. Reforestation will not help with extinction due to deforestation, either. Unfortunately, humans have already diminished the population of many species to such an extreme that they might not recover, even with a massive reforestation effort.


In addition to reforestation, some other tactics are being taken to counteract or slow deforestation. Some of them include shifting the human population to a plant-based diet. This would lower the need for land to be cleared for raising livestock.


Global Forest Watch has also initiated a project to counteract deforestation through awareness. The organization uses satellite technology, open data and crowdsourcing to detect and alert others of deforestation. Their online community is also encouraged to share their personal experiences and the negative effects of deforestation.

Global Warming causes floods and droughts. Floods can destroy crops and droughts can cause crops to wilt due to a lack of water. 
Living things living on land which is near the ocean will have to find a new habitat because the rise in water level will cause floods, which can destroy their habitats and make it impossible to live in.
We could help reduce the negative impact on the environment by using the 3’Rs’ in our daily life and we can try reforestation to make trees grow back to where they used to be, so that they can photosynthesise and reduce carbon dioxide.]]> 2019-07-17 13:53:09 UTC https://padlet.com/Imelda/humansimpact/wish/371450360 Muhammad https://padlet.com/Imelda/humansimpact/wish/371451684
Pollution will change the environment by making it impossible to live in. We pollute the environment by dumping oil and other dangerous/toxic chemicals in water. This will cause the animals living in the water to die due to a lack of oxygen or other animals that are trying to drink the water to die due to drinking the harmful chemicals. We also pollute the environment in our daily lives when we drive or litter. 
The living things that are living in or near the water polluted will have to move to another habitat or they will die. Animals that live in the ocean can also die because we throw our trash in the ocean, and animals living in the ocean mistake it for food and eat it, causing them to die while other animals get stuck in the trash until they get eaten by a predator or die of starvation. 
We can help reduce the negative impact on the environment by using the 3’Rs’ in our daily lives and we can also help by donating to companies which use the money donated by cleaning the ocean. We can also reduce the negative impact by instead of using our personal vehicles which release smoke which contains harmful pollutants into the air, we can use the train and reduce the amount of smoke released into the air.]]> 2019-07-17 14:05:39 UTC https://padlet.com/Imelda/humansimpact/wish/371451684 Muhammad https://padlet.com/Imelda/humansimpact/wish/371453808 Deforestation will change the environment by increasing more carbon dioxide into the air, by causing Global Warming, by causing soil erosion and by causing the land to become dry due to less rainfall. When trees are cut down, they release carbon dioxide into the air, causing the amount of carbon dioxide in the air to increase, causing global warming. When trees are cut down, there are lesser trees photosynthesising, causing lesser carbon dioxide to be turned into lesser oxygen by the trees, causing there to be an increase in the amount of carbon dioxide in the air, causing global warming. When trees are cut down, animals lose their habitats, causing them to die or look for another habitat. When trees are cut down, soil  easily gets carried by water or wind into water bodies, causing the animals living in the water bodies to die or move to another habitat. Soil easily gets carried by water or wind when trees are cut down due to soil erosion, which occurs when there are no more or lesser trees holding onto the soil. When trees are cut down, there are lesser trees transpiring and releasing water vapour into the air, causing lesser water vapour to lose heat and condense into lesser water droplets, forming lesser and smaller clouds, causing lesser rainfall, causing the soil to become dry.
The living things living in water bodies will either die or have to move to another habitat due to the soil in the water bodies polluting the water. The living things living  in the forests will have to find another habitat or they will die due to the cutting down of the trees. Animals living in the soil under forests will either die or have to move to another habitat due to a lack of rainfall which caused the lack of water. 
Some ways we can reduce the negative impacts on the environment is by practicing reforestation and by spreading the awareness of what happens when deforestation occurs and how it can make many animals go extinct. We can also practice the 3’Rs’]]> 2019-07-17 14:25:05 UTC https://padlet.com/Imelda/humansimpact/wish/371453808 Muhammad https://padlet.com/Imelda/humansimpact/wish/371455102
  • Depletion of natural resources can change the environment by causing materials like metal and minerals to reduce until there are no more left since they cannot be replaced. Other things like fossil fuels, wood and more will either take a Long time to be replaced or they will never be replaced.
    Humans are over-fishing and causing the population of fish to decrease at an alarming rate. This can cause fish to go extinct and it can have a lot of effects on other animals that feed on the fish or other animals that feed on the animal that feeds on the fish and so on.
    We can reduce the negative impact on the environment by using the 3’Rs and conserving our natural resources. We can also help by using renewable sources of energy and other things instead of fossil fuels and other things.

Pollution is the introduction of contaminants into the natural environment that cause adverse change.Pollution can take the form of chemical substances or energy, such as noise, heat or light.Major forms of pollution include: air pollution, water pollution, noise pollution, plastic pollution, littering and more. Pollution will make our environment less healthy for not only humans, but also other living organisms like animals and food crops. Pollution will affect our health and diseases which may lead to death.
    2. Types of pollution include water pollution, air pollution, noise pollution, littering and more. Air pollution may cause asthma, lung cancer, damages to the immune system, endocrine and reproductive systems, and heart problems. Air pollution includes the release of carbon dioxide into the atmosphere which causes the Earth to become warmer and this leads to global warming. For children, poor air quality reduces oxygen levels, which impacts development. For the elderly, the small smoke particles that enter the lungs may be impossible to remove. Water pollution account for the deaths of 3,575,000 people every year and the majority of these are children. Water pollution may cause Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. It also causes marine animals to die, causing some of them to be close to extinction. For example, oil spillage in the sea causes many marine animals to die. Plastic pollution also affects animals. For example, sea turtles mistaken plastic bags thrown into the sea as jellyfish (their prey), causing them to eat the plastic bags and die. Many animals like seagulls and sea turtles mistaken plastic as food. This causes them to die. These animals may go extinct one day, affecting the food chain.
    3. As I am typing this, an estimated 217,360,000 tons of hazardous waste have been thrown out globally this year and 1,152,000,000 tons of waste have been dumped in oceans globally this year ( Yes, just to let you people know, don't ask). The good news is every positive action counts. Firstly, we can use less plastic by bringing a recyclable bag for groceries, recycle plastic bottles by planting plants in them and using fewer plastic straws. By practising the 3Rs, Reuse, Reduce, Recycle, we can also save the environment. Do NOT litter in the ocean and don't dispose of chemicals, paint, in water supplies and drains. Remember to read labels to ensure that the products you buy are sustainably sourced. Together, we can make our world a better place to live in in the future and I know I sound like some kind of person in a talk right now but SERIOUSLY, DO YOUR PART!

Global warming is caused by greenhouse gases which trap heat from the sun. Due to deforestation, burning of fossil fuels for energy and more, carbon dioxide (a greenhouse gas) is released into the atmosphere and the Earth will become warmer.
    2. Global warming will cause heatwaves to be more common, melting ice caps which contribute to the rising sea levels, floods and droughts to be more common and the number of wildfires to increase. Habitats may also be destroyed, causing animals to die. Right now, animals are already moving to colder and higher areas. Those who cannot migrate to more habitable areas may go extinct. Economies will also fall and billions of dollars will be spent repairing damages and sustaining people.
    3. The temperature of the world has increased by about 0.8 degrees Celsius for the last three decades and the sea level has increased by about 27 cm since 2000. We can use more renewable sources like wind mills and solar panels. Recycle glass bottles, jars, magazines, newspapers and tin cans or throw them into one of the recycling bins. Only fill the kettle with the amount of water needed. Take public transport or cycle more often instead of taking a car. Use both sides of a sheet of paper before throwing it away.

    2. it can cause  flooding and the living things such as turtles population will decrease as the eggs on the beach will be flooded before the turtles can hatch and will drown them.
    3.we can use lesser aircon and use more of the fan when the weather is not as hot. we can also remember to switch of the lights and fans when we leave a room , e.g. like in school. when we have to go home we can switch of the fans, light,...we can also place solar panels on the roofs of our house.

When we cut down trees, the trees release carbon dioxide that they contain before being cut down. the carbon dioxide then leads to global warming , causing the world to be warmer.
    2.the living things that lives the trees will lose their habits when we cut down the trees. they will not have a place to stay and that population of animals will decrease and could possibly go extinct! humans are also another living thing that could go extinct. 
    3. we can support reforestation and write on both sides of paper :)
    P.S. trees have life like us too! So, why should we cut them down just so we can be satisfied? ]]>     2019-07-18 08:56:38 UTC https://padlet.com/Imelda/humansimpact/wish/371556558     BeRnICe Wu https://padlet.com/Imelda/humansimpact/wish/371557567 when the our natural resources deplete, things will be harder to replace or may not be replaced again as we do not have enough resources for it to happen. If the trees cannot grow fast enough to replace the ones we have cut down, we would have not enough oxygen  and we & the trees could go extinct. We stop cutting down so many trees just for land and all.]]> 2019-07-18 09:09:02 UTC https://padlet.com/Imelda/humansimpact/wish/371557567 Hui En https://padlet.com/Imelda/humansimpact/wish/371557707 1.  Deforestation is the permanent destruction of forests in order to make the land available for other uses. People cut trees down in order to make paper and wood. They also do this to make space for buildings like houses. Deforestation destroys forests which are habitats of many animals. This will destroy the habitats of many species, leaving them exposed to danger. These animals will not survive and may go extinct if we continue this. When we cut down trees, carbon dioxide stored in the trees to photosynthesise will be released, contributing to global warming and the Earth will become warmer. Plants and trees take in carbon dioxide to photosyntesise and give out oxygen. When they are cut down, less carbon dioxide which traps heat and makes the Earth  warmer will be absorbed by the plants.
    2. Habitats will be lost. In fact, three million people live in forests and there are still many species in the forests that have not been discovered. Forests also create a place for recreations and pastimes.  Eighty percent of the world’s known terrestrial plant and animal species can be found in forests, and tropical rainforests are home to more species than any other terrestrial habitat. When these animals' habitats are lost, these animals who depend on the forests will die. These species may go extinct, affecting the food chain.
    3.  An estimated 18 million acres (7.3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year and about half of the tropical rainforests in the world have been wiped out, according to the United Nations' Food and Agriculture Organization (FAO). We can use both sides of a sheet of paper before throwing it away. When shopping, move towards buying recycled products mainly. Reuse wrapping paper by using it again. Recycle magazines and newspapers. Plant trees for animals who have lost their habitats.

Pollution will worsen the conditions for us to live in .for example rubbish thrown onto the floor will give off a bad smell and make the place look very dirty.
    2.for example , if rubbish is thrown into the water ,aquatic animals such as turtles ,dolphins and other tropical fish will mistake the rubbish as food and consume them even though it is actually not edible , if this continues to happen,the marine animals will fall sick and eventually die.
    3.we can not throw rubbish onto the ground ,instead , e[we can throw them into the rubbish bin or the recycle bin.we can also refrain from using too much plastic by not accepting plastic bags given to you when buying things from a store and not using one use items like wooden breakable chopsticks.we can use a recycled bag to save plastic.]]>     2019-07-18 09:34:35 UTC https://padlet.com/Imelda/humansimpact/wish/371559442     Hui En https://padlet.com/Imelda/humansimpact/wish/371560068 1.  The way we’re living, we are already using 2 to 3 times more of the Earth’s natural resources than what is sustainable. If we do not act now, we will see the consequences of depletion of natural resources.  The top 3 natural resources being depleted are: water, oil and forests.
    Water
      The depletion of our water resources is more serious that the current oil depletion. There are substitutes for oil but nothing can replace our drinking water.  Only 2.5% of the world’s total water volume is fresh water. Of that 2.5%, 70% is frozen. Yet,  70% of the available fresh water that remains in used in agriculture, 20% in industry and only 10% is being used for human consumption. The consequences are drinking water shortage and food shortage, which will lead to famine.
    Oil
    Nothing can be moved, manufactured, transported, built, planted, mined or harvested without the liquid fuels that we get from petroleum. Oil is a non-renewable source of energy and accounts for 40% of the energy we use. The consequences are less transportation, smaller economies and higher prices.
    Forests
     An estimated 18 million acres of forests are destroyed each year. Half of the world’s forest has been cleared.  Trees absorb greenhouse gases and carbon dioxide and produce the oxygen we breathe. Forests are the habitats of millions of species. The consequences are soil erosion, global warming caused by the rise of greenhouse gases,  extinction of species and loss of biodiversity and Flooding and drought.
    2. Humans, animals and plants will soon run out of these natural resources, causing us to die. If we do not act soon, more people will die of thirst in the future and more habitats will be lost which will cause extinction of animals.
    3. Estimated 30,000,000,000 tons of resources have been extracted from Earth globally this year. We can do the following to reduce the depletion of natural resources:
    - cycle, walk or use public transportation whenever possible
    - turn of all appliances when not in use
    - conserve electricity
    - fix leaky faucets and use recycled water for flushing your toilet
    - Harvest rainwater when you can. You can use it for cleaning or watering your plants
    - Shower within five minutes

When trees are cut down, the carbon dioxide stored in their trunks (which is taken in for photosynthesis).With it being released into the atmosphere and trapping heat, carbon dioxide can cause the rise of global temperatures, not to mention that without trees, we have nothing to take in our carbon emissions, leading to even higher temperatures.
    In addition, water vapour, another greenhouse gas, is also affected by the impact of deforestation and these changes in their atmospheric concentration will have a direct effect on climate. An example is  global vapor flows from land having been decreased by 4 percent, which can disrupt natural weather patterns and change current climate models due to the exchange of water vapor and carbon dioxide between the atmosphere and the terrestrial land surface. This might cause disruption in animal migration patterns, and wind and water currents.
    Yet another effect of deforestation is soil erosion. without the tree roots to hold the soil together, the soil will fall apart, and the worse effects are soil polluting both wind and water bodies/sources, and disallowing animals to have fresh air to breathe or clean water to drink ,both of which are essential for survival. This might not only affect animals, but humans too,    with soil erosion leading to vegetation growth problems in the long term as soil becomes less nourishing and weeds begin to reappear over years of use, even though the ash from the burned trees provides some nourishment for the plants and also ensures that land is weed-free at first.
    Together with the above stated, there is also habitat loss to consider.
