Hello! Note: pictures will be at the end.
First.

I will be talking about the main causes to ecosystems destruction

Pullution

Pullution is very bad, it's caused by humans, they pullute the land, air, water and this is destroying ecosystems. Humans are producing 300 million of plastic each year. And over 5 TRILLION pieces of plastic in the seas. The plastic in the oceans has devastating effects on wildlife. In 2017, for example, a beached whale discovered off the coast of Scotland died because of the amount of plastic it had consumed – about nine pounds of plastic bags were found coiled in its digestive tract.

Global Warming

The majority of plants and animals live in habitats with specific climate conditions, so any change in the atmosphere can affect the plants and animals living there, as well as the makeup of the entire ecosystem. Climate change has been shown to affect animals and plants in a variety of different ways. According to John Wiens, professor of ecology and evolutionary biology at the University of Arizona, animals respond to climate change in a main way. Animal species can move to track their original climate. Or they might stay where they are, and possibly change their behavior or evolve to accommodate the new conditions.

Land Clearing

As the human population increases,so does the need to develop more land. Many ecosystems are destroyed in order to clear land for housing developments and roads.

Resource Exploitation

As more ecosystems are rich with resorces like nutrient-rich soil, water, trees and fossil fuels. Excessive efforts to extract these resources like mining, logging and oil drilling contribute to ecosystem destruction.

Population Decline

An ecosystem's animals are vital sources of food and population control. Many animal populations are declining due to overfishing and hunting. Animals are often hunted for their valuable skins, plumage, horns and meat.

Problems solved.

For Land clearing we should not use so much paper. To solve that you can use both sides to instead of two papers! And for pullution i think we should use eletric-powered stuff instead of gasoline cars, trains. For Resource Exploitation we can not destroy the whole ecosystem as it would destroy the animals habitats. For Population Decline we can use fake material for clothing, blankets etc. For Global Warming we can Reduce water waste, actually eat the food you buy—and make less of it meat. That's all the problems solved in my opinion, but i'm not done yet, i'm going to do who, what, when, why, where questions.

Who is dying?

Animals are dying from the humans. Not every human kills animals though, which is good and i would do the same.

What if every animal dies in the entire world?

Well, a lot of plants would then die off as well, because there are many plants which depend on animals for their reproduction, every human would die because plants make oxygen for humans.

When were humans destroying most ecosystems

This has been happening for about 25 years now.

Why do humans think this is fine to do?

Because they think destroying ecosystems will do nothing to the animals.

Where are ecosystems are located?

Ecosystems are located mostly in forests, parks, rivers and much more

Conclusion

Humans destroy ecosystems because they need rich material for blankets, clothing and much more to sell and make money. Now for some pictures as they're shown below.
