Overall Human Influence Many types of human activities affect Desert biome If you run vehicles over desert you can scar soil and it can be scared for many years Car tracks can kill vegetation Animals that rely on desert can be harmed

Atacama Desert Location: Northwest Chile Landscape: Dry, Mountains, sandy, rocky, some valleys Human impact: This desert has a hand sculpture (finished in 1992) which COULD lead to destrohind ecosystems

Patagoian Desert Location: Argentina and a little in Chile Landscape: 7months winter 5months summer, rocky, valleys, cliffs, streams, sandy Human Influence: Some humans have lived here mostly to herd goats and sheep. Also for oil, gas, and coal. About 5% of Argentina's population takes over 28% of the territory of the desert.

Kalahari Desert Location: Southern Africa Landscapes: Sandy, rains ( frequently in winter and little in summer ) Total= 100-200 mm. per year Human Influence: Tourism can often get in the way of daily routines and animal ecosystems. In the end it only has minimal impact.

Aribian Desert Location: Egypt and Iraq Landscapes: sand dunes, some cliffs Human Impact: Humans haven't really affected this desert. Although the demand for more shopping malls around it could end up affecting the desert.

Taklamakan- Gobi Desert Location: Middle of Russia Landscapes: high mountain ranges, sandy ( partly ), mostly lowlands ( besides the mountains ) Human Influence: This area is usable for farmland. It is still affected from the Asian monsoon.

Thar Desert Location: Northwest India Landscapes: grass spots, few trees, sandy, hilly, some parts have bunches of plants Human Influence: Humans have not really affected this desert in any way.

Chihuahuan Desert Location: Southwestern U.S Landscapes: some plants, rugged ground, some hills, flat other than the few hills, very little rain fall Human Influence: Jas many human activities, tjis could potentially affect the ecosystems in the desert.

Sonoran Desert Location: Northwest Mexico and southwest U.S Landscapes: very full of plants, hills, boulders, and sand/rock mixed ground. Human Influence: There were native tribes in the pre-colonial times who lived in and around this desert. It has destroyed the desert with over harvested plants

Tanami Desert Location: Northern Australia Landscapes: very little plant life, sandy, muddy ( in some areas ), hilly ( UP AND DOWN) Human Influences: It ahs been unfavorable to humans living in these areas. But the human activities can still bring harm to the ecosystem's.

Sahara Desert Location: Sudan and Libya Landscapes: somewhat flat, has some dents in the ground, rivers, some plant life Human Impact: humans have been living in these areas for a long time. They hunt the animals which is bad for the ecosystem.
