Deforestation is the destruction of natural forests, due to the felling or burning of trees, in order to obtain materials such as wood and paper, and others. Or to have land for construction or projects.
This affect the environment, extinct a lot of species of plants, and they take the home of many species of animals. To reduce deforestation, some things we can do are use recycled paper and also recycle it to be able to do it, talk more about this problem so that people are informed and more aware, we can also plant trees to try to recover the forest land. As the consequences of deforestation affect us all.

Water pollution occurs when harmful substances often chemicals or microorganisms contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment. with this liquids or chemicals the live things dead because the water is dangerous and if you drink some of this water you can dead or give you a strong infection or the fishes that they oxigen is the water

Water polution is one of the types of pollution that exist in all the planet  and this is affecting all the animals that live in the ocean Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.

The water pollution is a problem that we are causing because all the products or materials that we use for our necesities, this actions or things make the ocean dirty and toxic for sea animals that live there. One solution could be replace the plastic for organic materials so we prevent that sea animals eat that becasue they confused the plastic with food. An second solution could be recycle becasue with that we can stated using this materials with other porpuse.

The pollution is caused by man-made, because there are cars and littering. How to deal with it
Humans should use trams instead of littering

My idea to give a soluttion to this problem is lik in our house we can have trash cans to recycle, reuse, and reuse. You could also use the reusable things to do things like with tires, seats or bottle pots and go using the already used paper.
We could stop using both transport and cars since smoke also greatly affects climate change and the ozone layer.

I think that they should not kill endangered animals because most of them are very useful on planet earth, each one has a cycle and every cycle is important, so if they kill an animal they break their cycle and some animals would not have to eat and It seems to me unnecessary to kill animals for clothing because they do not need that type of material to make something beautiful, clothing brands overvalue clothing and that makes people think the more expensive the better and people also overvalue brands because of Example: Because all of Nike's things are necessarily better than a common clothing store, it may not make a difference but people make that brand raise its prices and have to kill more animals.

the massive extinction of animals is for the human being, all the problems of this world are for us, this world so rotten and horrible, you cannot look for the beauty of a stage in this world .. all the beautiful things are opaque and there's no hope. We kill all animals. More than 30 percent of animal species are becoming extinct and the solution that I give to this is, more education for minors about animals in danger of extinction and campaigning internationally to help them. make more rescue centers and make more zoos as shelters for these animals that no longer have a home to exist. the human being is a plague and must be exterminated. people have to be recruited to take care of the places and sanctuaries where these animals are instead of taking them to war. more education, more campaigns, the world will be solved thanks to us. the new generations.

Overpopulation is caused because there is many people in this world, this cause the global warming and the climatic change in the earth because this leads to consume more resources also the overpopulation make us to need more space making us to destroy more ecosystems, so after we know the problem we have to give solutions to it.

Some of the solutions we can have are:
Promove the family planification avoiding with this the more reproduction of humans in the planet another solution can be the legislation of just one children per family reducing the poblation and finally other one could be to teach childrens to raise awareness this big problem and finally investigate about the problem and know about more solutions.

The human activity produces 8 million metric tons of waste each year and all of it goes to the ocean. The bad thing is that the amount of waste is increasing. Several experts such as Emilio Muñoz Ruiz have determined that this annual amount is going to multiply by 100 in about 5 years. In my opinion and according to the information from the video, the solution is to make bacterias (sakaiensis) that have an accelerated metabolism, they can transform the plastic Pet into sugars and this is easy to make. As some people can say, it is evolution, but the advantage that we have using bacterias, is that they can reproduce so quickly, they are faster than any other living thing, appart from other micro organisms. On the other hand, many people think that these bacterias could be dangerous for us, but this is not true, the reality, is that those bacterias have been with us for a long time, the sad thing is that their process of work is really slow, so the way to help them is to use a process with Uv rays, that can make the plastic soft and then the bacterias are going to eat the plastic pet in an easier way.

The video that explains this topic in a better way is below.

Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface. Global warming, the gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere.

How we can prevent it?

1. Speak up!

2. Power your home with renewable energy.

3. Weatherize, weatherize, weatherize.

4. Invest in energy-efficient appliances.

5. Reduce water waste.

6. Actually eat the food you buy—and make less of it meat.

The Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund. The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors. Maybe if we can follow these alternatives we can stop this bad habit.

·         Seen another alternative, some good alternative is the hemp which is a plant that can grow in 8 months and we can make paper, plastic and other things but the best is that the hemp is biodegradable

·         Reforestation, the reforestation must be obligatory because that’s the way of preserving these habitats and the biodiversity that they contain

·         Start using less, if we start using less paper and start using the necessary they start producing less paper and giving an opportunity to trees grow again

·         Make most of these areas protected and forbid the deforestation in them

With these alternatives we are taking care of our planet and all the beautiful creatures that are in it.

I think this is a rare problem, but it does matter. The reasons are because for example: if the Spanish bring a tiger to America it would be stronger because the animal is not accustomed to the height of America, it could cause chaos for the habitat of animals that are from America, among others (Example) . And it could also damage the ecosystem and we would lose what we know today. And it is also because their skins are used to make coats and so on, and it is not correct. From my point of view I believe that you should not do any of that because wild, domestic animals deserve to live and be free, that is why you never have to take the animal to an unknown habitat because it is not known what actions would trend, what would it do, what harm would it do? ...

My idea to solve the pollution or a good alternative is that first that in the whole city there are garbage cans in the streets, second that people have the manners to vote the garbage in their place, third that people avoid going out with cars and go out in Walking or cycling, another thing to avoid contamination is that there are no factories and that instead of factories there are people who dedicate themselves to making artisanal things without the need to pollute.

I consider that a problem in our current society is the decline in biodiversity, this is due to the fact that human beings exploit natural resources and with this we endanger terrestrial and aquatic ecosystems and thus all biodiversity to the point of being able to disappear it. So taking all this into account we should pay more attention to this problem and look for alternatives or solutions, such as adopting a more sustainable and  friendly life with the enviroment since we also depend on biodiversity. A very good and interesting alternative is to carry out campaigns in schools, towns and in our own homes so that adults, children and young people become aware of the great damage we are doing to biodiversity, in these campaigns the importance of violence will be taught and what we lose by damaging it, alternatives will also be taught to guarantee a better life, one of these alternatives can be to consume sustainable products, not have exotic species and much less abandon them, act responsibly with what we consume, waste and use, among other things since human beings and all biodiversity depend of these small changes.

Plastic pollution, i think it is one of the most common, when it is discarded, it remains in the enviroment for many years. Also, when it is thrown in the streets, it can end up covering gutters and grates where the water must pass when it rains. When it reaches rivers and oceans, it can kill animals the are trapped inside the bags, among other problems caused bye this problem.
Some ideas that could be used to help reduce this problem: Avoid buying water in plastic bottles, I think stores should promote or sell those bottles and not  the common plastic ones. Forget the plastic straws: As I said before lol, there are straws but not all, so I think all stores should use it. Put up signs and stop selling food containting  plastic in school cafeterias, that would definitely help a lot... well lol, i think those would be some ideas to stop the plastic pollution.

I would think that a great idea would be cartboard day. Cartboard is used by many people, so much so its making a big problem. So, once a month, theres a big day called cartboard day, were kids make toys, puppets, boats, and more to make activities, like puppet shows, car competitions, or even a battle with cardboard. The youngest will use no harm materials like scotch tape, rulers and pencils, because the supervisor may cut those. Th older, they may even program their toys. You would leave with many toys, of course if you created them. The materials would be brougth by supermarkets waste, asking to your neighbors to give you cartom or maybe brougth by the participants to make their own thing they want.

I think that one of the most contamination problems is air pollution because we as human are producing a lot of it when we go in the car, burn things, fossils fuels, industries and many of our activities produce air pollution so I think that in our houses we can do an alternative to that problems, I propose a solution that is to do a vegetable patch in our houses because if you do one, you could help to absorb some the carbon dioxide gases that are produced in the streets, in your city or in the place you live and start recycling that carbon dioxide, as well when the vegetables and fruits are going to be rotten or are rotten sometimes this action produce carbon dioxide so in your vegetable path you could recycle that fruit or vegetable and use it as a fertilizer. Also, you can recycle bottles, cans or some recipients because in there you can plant some different types of vegetables and fruits, or flowers. In that way you can help to reduce a little bit this problem and start reusing the things you would throw, so help in many ways to the environment.

The main reason for the loss of biodiversity can be attributed to the impact of humans on the world's ecosystems. In fact, humans have profoundly changed the environment and territory, directly developed the species through fishing, hunting, etc., changed the biogeochemical cycle, and transferred the species from one area of ​​the earth to another.Threats to biodiversity can be summarized as follows:
1. Alteration and loss of the habitats
2. Introduction of exotic species and genetically modified organisms
3. Pollution
4. Climate change
5. Overexploitation of resources

The water is also a big problem that we are doing to the Earth, basically we waste the water and also we use damage products that when we finish to use them they go directly to the ocean. That cause that a lot of sea animals eat that garbage and also get stuck. Exist a lot of solution or forms to help to reduce this problem, one of that solution could be use reusable or organic products, it means stop using plastic and replace them with metal or organic materials. Other posible solution ould be that we can started using only the necesary water that we need, I mean to stop leaving the bathroom faucets open.

A good alternative to reduce environmental pollution for me would be to put plates on at least 40% of the cars in at least one country on each continent, at least 2 days a week. What should cause these plates is that people use less vehicles since they would be forced to use public transport, for example: The capacity of a public bus is approximately 46 people. If we could get those 46 people to use public bus instead of using 46 cars, the public bus would pollute less than 46 cars.

Think about the impact humans have on the environment: overconsumption, overpopulation, land loss, mass extinction, decline in biodiversity, acid deposition, ozone depletion, pollution.

1. Propose creative alternatives that we can implement (at home, our school, in the city, etc.) that will help us reduce our impact on the environment.

Be creative, you can use images on your post.

Write at least one paragraph.
