Can you please tell me the effects of human activities on ecosystems. Example Human Activity and Consequences....

Answer 1

We've mowed down the tall grass and cut a lot of trees to plant food crops. We've disturbed habitats by building homes and business buildings. We've paved over good land for roads and parking lots. We've spewed pollutants in the air, killing some vegetation and animals.

Here's a lot more information.
