There are many different ways that an ecosystem can change.  One way an ecosystem can change is pollution.  There are many different types of pollution.  There is water pollution, air pollution, etc.  Another example is natural disasters.  Those include hurricanes, tornados, droughts, famines, etc.  A third way an ecosystem can change is by waste.  When we are done with things (trash) it will go to landfills.  Some of the trash is not biodegradable, which means that it will not break down naturally.  Another issue with landfills is that some of the trash like weed or bug killer is toxic, and can be very harmful to the environment.

Their are many ways to cause change in ecostems. Here are some examples . Pollution is a big way . People can pollute the water and it can change an ecosystems . A second way is construction it can  knock down trees that birds live in.Third way is storms that can ruin a lot of animals habitat.

# data[].attributes.body
Some reasons that ecosystems change is pollution, natural disasters, and people introducing and taking away animals from the environment.

# data[].attributes.body
#1 having a animal removed from the ecosystem and being kill till they had to move.
#2 natural disasters such as Tornados,Volcanos and floods
#3 people releasing palution in the water in the air and to the soil.

Ecosystems can change one because of Natural Disasters like earthquakes, floods, storms, hurricanes volcano's, drought's and other Natural Disasters. Another way is a tree dies in the forest soon another will grow back. People can try to replace the damage but sometimes it takes a while and some you just can't replace them. Another one is by organisms like beavers they build dams that can cause flooding, but the dams can also be beneficial by creating new habitats and food supplies, large animals like elephants, can cause changes by trampling trees and seeding and like in the picture lava and stuff like that can cause Ecosystem changes.

One way is that some people poaching which is the act of over killing, or illegally killing animal for game. Which means that they can endanger or make a animal extinct. That would drastically change a ecosystem. Other ways that can change ecosystems is natural disasters such as droughts,floods,tornados, and hurricanes. They can tear down trees and animals will no longer have homes and eventually they will have to find a place to live. And finally there is pollution. The air pollution can cause birds no to be able to see well. The water pollution is even worse because it kills all of the dead fish

# data[].attributes.body
#1. Water pollution is very bad, because everything depends on water.
#2. Poaching endangered species is very bad because other animals depend on it to.
#3. Cutting down trees is very bad to because a lot of animals live in trees and they would lose their habitat.

One way that an ecosystems ca change is that when people take bathes or showers we are washing of all the chemicals and waste that we produce and were does it go? To the ocean. Another way is that when people are throwing things away (witch is still bad) we throw away things with chemicals such as batteries, paints, cleaners, and oils are some of the most toxic ones. And the last one that I am putting is natural causes, such as earthquakes, floods, storms, hurricanes, volcanoes, and droughts. :D

*1 Toxic waste is the first thing on my list.
*2 Water and air pollution is the secound thing on my list because it improtnion but not much
*3 oil and smog is the third thing because it is can cause harm but not to much.
*4 Clear-cutting because that destogs anmails habbtes
*5 Natural events floods,droughts,and other natural disasters.

Ecosystems can change in many ways. One way is natural disasters, like a volcanic eruption. Another way is by the organisms that live in the ecosystem. Like a beaver building a dam.  The last way to change an ecosystem is by humans doing things like polluting the water, even if it is on accident.

# data[].attributes.body
3 ways that ecosystems can change are, natural disasters, also people can cause pulloution ,and the last way is if a new speices is introduced to the environment it can be harmful.

# data[].attributes.body
There are many ways an ecosystem could change. One way is natural disasters. Natural disasters consist of tornadoes, thunderstorms, volcano eruption, etc. Another way is pollution. Pollution is when the air is polluted, it means it is hard to breath  good and healthy air. The last one is poaching. Poaching is killing things that are illegle to kill. There are my 3 things that could change an ecosystem

# data[].attributes.body
Here are some ways a ecosystem can change natural disasters, oil spills, and invasive species. So those are some ways a ecosystem can change, but here are a lot more than just these three.

# data[].attributes.body
The ecosystems can change by pollution, natural disasters, and dams.

# data[].attributes.body
1. Natural disasters. Like tornadoes,earthquakes,volcano eruptions and so on. 2. Polution. say an incinerator making so much smoke it fills the sky.
3. Air and water polution. Man made building making smoke and smog.
4. Overpopulation.Or inbreeding is when an animal has too many of its own kind, so there would be nothing left for their food or other animals food.5. Poaching.Say elephants they are being illegally hunted for their ivory tusks and then left to rot.
6. Over-hunting.People hunting the animal almost to extinction
7. Habitat destruction.Like man made buildings killing all the trees that the birds live in.
8.  An animal going extinct. say the wolf went extinct all of the grass eaters would thrive and eat all of the grass leaving none for the other animals that need some of the grass.
9. An animal being taken away from its habitat.Say a(n) wolf the elk deer and bison would overpopulate. Therefore there would be no grass for the grasshopper so that would make the grasshopper population dwindle. Then the mice, and snakes, and the birds and so on.

If a new species is introduced, it can change the ecosystem drastically. Also, if a species dies out, other predators that mainly rely on that species have no or very little food. Another way an ecosystem can change is if a natural disaster occurs,  it can harm the land and habitat of a species.

# data[].attributes.body
There are many ways that ecosystems can change, and here are three. The first way is a wildfire. A wildfire can take out a certain organism in that area and that means that other organisms could die out or overpopulate. The second way is man-made structures. In order to make a lot of things, you have to clear things out. When you clear things out, animals lose there homes. The third way is pollution. when water or food is polluted, animals die of poisoning. Then other animals will overpopulate or die out.

# data[].attributes.body
There are many changes in a ecosystem like weather . If there was a storm like tornado or hurricane it might destroy a animals home. Also there is pollution like if there was pollution was in the water animals would be affected and might get injured. One other way is if a species gets overpopulated then a food chain will be disturbed because animals will either have less to eat or will become over populated because there are to many animals eating them and a species becomes endangered. Those are my three ways an ecosystem can change!

# data[].attributes.body
the first is hurrican and tornadoes . the next is beavers bulding dams and humans because the factors and even flushing a toilt.

# data[].attributes.body
1. Natural disasters can damage a habitat.
2. Dams can cause floods.
3. Air pollution is bad for the enviroment.
4. Water pollution can make all the fish die.
5. Building roads can seperate families.
6. Invasive species can eat another animal's food.
7. Soil erosion can effect the plant population.
8. Parasite spray is bad for the animals that eat that plant.
9.  Humans demolish habitats by chopping down trees.
10. Bridges can cut off water flow.
11. Oil can disable birds.
12. Population problems can effect the entire food web in an ecosystem.

# data[].attributes.body
Ecosystems can be change by man made buildings and roads.Also by air pollution and smog, which can kill animals and ruin the ecosystem.Mother nature can be a big factor  in animals if there is a wild fire caused by lighting can kill animals and destroy homes. or if a new species is  intoduced it can kill to many of the same animal and it can change the ecosystem.

Eosyststems can be changed by humuns, natuer, or animals. One way is an earthquake. Another example is a beaver dam. A third example is mining.

Ecosystems can change by man-made structures. They can also change by waste (radioactive, nuclear, etc.) The last way an ecosystem can change is water blockage/contaminated water gets into creeks or rivers, than the organisms that are living there can't live there and they have to find a new place to live.

# data[].attributes.body
There are many changes of ecosystem, and the possibilities have many varieties
1. Land/Air/Water Pollution (Humans)
2. Beaver Dams (Organisms)
3. Nuclear Elements (Humans/Mother Nature)
4. Fires (Humans/Mother Nature)
5. Development (Humans)
6. Natural Disasters (Mother Nature)
7. Warfare (Humans)
8. Invasive Species (Humans)
9. Viruses/Diseases (Humans)
10. Global Warming (Humans)
11. Chemical Releases (Humans/Mother Nature)
12. Poaching/Over-hunting (Humans)
13. Taking Animals (Humans)
14. Imbalance in Energy (Organisms/Humans)
15. Resources (Humans)
16. Habitat Deduction

Pollution is caused by Humans by adding harmful materials to the air, water, and land.
Beaver Dams made by Beavers can effect water flow and add habitats and food rations.
Nuclear Elements added by Humans or Mother Nature can effect the health of organisms.
Fires can take away homes and food rations. Can be caused by humans and mother nature.
The Industrialization of Cities or Buildings can take away habitats. But also add habitats for Humans
Natural Disasters are caused by Mother Nature and take away habitats and food rations. Can mend by Mother Nature.
Warfare is caused by humans and can cause destruction of food, habitats, land, for both humans and animals.
Invasive Species are caused by humans and can be good OR bad.
Viruses and Diseases can be carried by Humans or Mother Nature and can effect organisms, Nature, and Humans.
Global Warming causes destruction of Homes and Deaths of Animals and even Humans.
Chemicals Releases add chemicals to the air. Could be caused by Humans and Mother Nature.
Poaching and Over-hunting can decrease life and imbalance energy.
Imbalance in Energy can result in food being destroyed by humans and organisms.
Resources being taken from Mother Nature and Organisms can result in destruction in habitat.
Habitat Deduction can result in loss of homes and imbalance in Energy.

One way an Ecosystem could change is a hurricane . Another way could be Volcanoes erupting and could hurt a animals home .  Finally a earthquake could cause many homes could be destroyed . There are many ways that things could cause the Ecosystem to change here are just a  few . ( also people can by pollution ) .  Storms could destroy many things . There is flooding that could destroy something but also without any water  ( drought )could cause a  change .  Humans build thing like roads and other thing and by cutting down those trees could cause a animal to loose its home . and the last one out of the many is natural change . These are the few ways that the ecosystem could change .

Droughts can affect rivers and lakes by drying them up , Hunting can affect all species almost everywhere and to top it off... Pollution because in air pollution it hurts animals everywhere. A new species could be eating all the hemlocks and nothing eats it in the new country. So animals have a lot of stuff to worry about.
Here is my top 10 list...
1.Any Pollution
2.Natural Disasters
3 Beavers(It cuts trees and blocks water)
4. New Species
5. Extinction
6. Oil
7.Over Hunting
8.Mining
9.Soil Erosion
10.Virus

One way an ecosystem can change is air pollution. It says in the text, "Urban growth brings more vehicles that emit gases and leak oil, polluting the atmosphere and the ground."
Another way is dams. Beavers build dams out of mud, sticks/twigs, and stones. This decreases water in some parts of the river/creek, but it can also cause flooding.
Another is coral reef. They do create habitats for other living organisms, but they can also be really bad. "Red tides is a sudden explosive growth of single-celled algae in coastal areas. Red tides can occur when nutrient-rich deep water gets brought to the surface after a storm. With so many nutrients in the water, the algae keep reproducing. The toxins produced by the algae can cause organisms that eat the algae, such as small fish, to die. This reduces the food energy available for predators who eat small fish."

One way an ecosystem could change could be by a hurricane . Another way an ecosystem could change could be by pollution. One more way an ecosystem could change could be by an earthquake. A beaver dam could even change the ecosystem. Fires could change the ecosystem. Volcanoes erupting could change the ecosystem. Us humans building buildings could even change the ecosystem. Warfare could change the ecosystem.People that bring a new species to our country could even change the ecosystem. I named some of the things that could change the ecosystem, but there are many more things that could change the ecosystem in the world.
