Resources

• Identify different natural resources using the photograph at the right.

• Explain how humans have used each resource and then identify some negative impacts of this use

Resource : Water

• River: water– Fishing, – irrigation– Recreation– Domestic/industrial– Waste– transport

• Negative:– Flooding– Pollution, leached

chemicals from farming, urban and industrial waste, acid rain, oil from cars and boats

– Impact on fish, dams (ladders) habitat destruction

– Delta, less silt

Resource : Forests

• Housing, building material• Jobs, taxes, good for the

economy• Recreational, parks• Buffer zone, remove CO2

add O2• Stabilize soil, reduce

runoff, filter water• Cool urban area, climate

• Trees cut for human use

• Soil erosion• Increased run off• Silt from runoff enters

the river, impact on aquatic life

Resource : Soil, Flood Plain

• Agricultural use

• Roads

• Railroads

• Recreational

• Residential

• Industrial and commercial

• dams

Negative Impacts

• Irrigation , fertilizers and pesticides

• Salinization and pesticides enter ground water and adjacent river ecosystem

• Leads to soil degradation

• Oils, salts and other toxic substances enter air, soil and river system
