Question

seminar on topic role of human activities in changing earth surface
​

Answer 1

Answer:

Humans build towns, cities, and roads. We make

farms out of prairies and forests. All of humans'

varied activities transforms forests, grasslands,

wetlands, river basins, etc. into less complex and

in many cases (e.g., pavement and lawns)

essentially sterile areas. These human

transformed areas are now roughly HALF of the

land area of the entire planet and are increasing.
