Answer:
A lot of use of agricultural land into non-agricultural land. Lots of trees are cut down thereby reducing vegetation for human needs. More and more fuel is used which causes the air to become hot.
Explanation:
South America has a population of more than 562,000,000 people (in 2010), a 3-fold increase since 1960.
The surge in population was due to high birth rates and improvements in the health system so that mortality rates also declined. It is estimated that 1/3 of the population of South America is under the age of 15 years.
The area of South America is 8 million km² with an uneven population distribution. Density of 27 people per km². The central and southern regions are populated with little or no inhabitation, covered by dense forests. Meadows, dry deserts, high mountains are also rarely inhabited. Population concentrations are on the banks of rivers, coastal areas and fertile highlands.
The impact is a lot of use of agricultural land into non-agricultural land. Lots of trees are cut down thereby reducing vegetation for human needs. More and more fuel is used which causes the air to become hot.
This warming of air will then have an impact on the natural destruction and melting of polar ice and then changes in the behavior of living things.
