Question

What is atmosphere and human impact on earths surface?

Answer 1

Our most obvious impact is on the land, where more than 80 percent of Earth's surface has been marked by human activity. Our terrestrial transformations go back at least to the beginnings of agriculture more than 10,000 years ago. Over the centuries, population growth and improved transportation have driven humans to control ever-widening tracts of land, with grave consequences for the species and habitats there.

Exhaust and emissions from transportation and industry have fundamentally changed our atmosphere. And oceans, lakes, and rivers suffer from our pollution and overfishing.
