What You Need To Know
• Predict how the actions of humans may impact environmental systems and/or affect sustainability.
• Evaluate the possible environmental impacts resulting from the use of renewable resources & nonrenewable resources.
• Renewable & nonrenewable resources, environmental costs & benefits, monitoring of environmental parameters – why needed

Impact on Environmental Systems / Sustainability
• Soil 1. Agriculture (Monoculture)
- Loss of Nutrients in soil (Nutrient Depletion)
- Lead to soil erosion (Soil erosion is when no roots are left to hold soil in place, the soil can be easily washed away)
2. Deforestation
- The cutting down of trees.

Impact on Environmental Systems / Sustainability
• Soil3. Desertification
- Make fertile areas into deserts
• Water Pollution1. Biomagnification
- When concentration of toxins increase at higher
trophic levels.

Impact on Environmental Systems / Sustainability
• Urbanization- As modern society developed, urban areas
began to grow causing it urban areas grow into cities due to concentration of rural migration. Also cause of Industrial Revolution.
• Air pollution1. Smog
- Gray-brown haze formed by a mixture of chemicals.

Impact on Environmental Systems / Sustainability
• Air Pollution2. Acid Rain
- Rain containing nitric & sulfuric acids
3. Greenhouse Effect
- Burning of fossil fuels & forests releasing carbon dioxide into the air, a greenhouse gas.

Renewable & Nonrenewable Resources
• Renewable Resources- Air
- Water
- Sunlight
• Nonrenewable Resources- Fossil fuel
- Nuclear Energy
- Natural Gases

Impact of Renewable & Nonrenewable Resources
• Renewable Resources- Provide a healthier ecosystem- Can’t be used up- Provided by environment
• Nonrenewable Resources- Damages environment- May lead to crisis- Only a certain amount left

Why We Need Renewable & Nonrenewable Resources
We need renewable and nonrenewable resources because it’s what we use for power (Electricity), you may use it when you’re charging your phone, or the computer screen you’re looking at this every instant. These resources have taken a big part of our lives because we use it to power things.
