just wanting to destroy things
Population moving from rural areas to cities

soil erosion, loss of ability of trees to remove CO2 from the atmosphere, loss of animal habitats
more mercury and cyanide released into rivers
Flash flooding often occurs in city areas because
Roads, pavements, and buildings reduce the infiltration of water into the ground
Ground water storage is usually very large
Runoff decreases during precipitation
The heat generated by city areas decreases evaporation
What is a negative impact of mining?
Material left after ore is extracted can release toxic chemicals into the groundwater
Mining can improve the air quality where miners work
Quarries attract new species to the area
Mining can decrease soil erosion
What are some ways humans can reduce the negative impact on the lithosphere? (Choose all that apply)
After mining, we can return the area to its original state
Mine near large bodies of water to wash away the harmful chemicals
We can only cut down a small number of trees at a time planting new ones as we go
Add green spaces in cities to help control runoff
Plant crops on steep hills to prevent soil erosion
What is a possible consequence of agriculture?
Water pollution caused by soil erosion & the use of chemicals (fertilizer, pesticides etc)
Decrease in animal's natural habitats
Increase of flooding due to less areas for water infiltration
Provides jobs for many people
What is one pro of mining?
Very safe conditions for miners
No chemicals are washed into nearby water sources
Many minerals and ores mined are needed to make electronics
No animals ecosystems are disturbed
What is one pro of urbanization?
Decreasing the amount of pollution generated
Creating jobs and access to modern technology
Decreasing overcrowding in the countryside
Feeding the worlds population
