What Can You Do?

Mineral Resources Minerals are mined to make a profit. Ores are deposits of minerals that are large enough to be mined for profit. Extraction of Minerals

Advantages and Disadvantages of Using Land Resources ?

Deforestation Cutting of large areas of forest for human activities.

Deforestation Problems Soil Erosion Loss of habitats (complex ecosystems that can take hundreds of years to be replaced) Global Climates – trees absorb carbon dioxide (CO2) from the atmosphere during photosynthesis. Increased atmospheric CO2 causes earths surface temperature to rise.

Pollution Affects water and soil quality. Runoff from mining and agricultural land use pollutes rivers and underground water supplies.
