Unfortunately, it is humans who primarily cause enormous harm to the ecosystem. First of all, in order to preserve nature, it is necessary to protect the forest so that it is not planted later. There is an organization called Greenpeace that adheres to its goal of conservation. First of all, pay attention to yourself, do not litter, do not pour waste into river canals and do not pollute our atmosphere, and then there will be no disasters on our planet.
I agree with what you say, it is true that currently it is difficult for people to be aware that the environment is being polluted, perhaps in the next few years it will cause more damage and many areas of mountain slopes are barren with abandoned land, a good solution is to replant them with trees for save the earth from global warming because many trees are cut down.
