Lifetime of a Tree

Humans have impacted the world in positive and negative ways. Some good things humans have done are planting plants, recycling and most of the time respecting the animals. I must admit people do some debatable things with our wildlife. I believe one of the worst thing’s humans do is pollute, pollution is bad because it affects the air quality for animals, plants and for humans. Human’s also done many more harmful things to the environment like urbanizing an area which may overpopulate a certain area which causes skyscrapers and cutting down many trees. Humans do genetic modification, climate change, and acid rain, which is caused by when chemicals like Sulphur dioxide get released in the atmosphere.
