2 What You Need To KnowPredict 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

4 Impact on Environmental Systems / Sustainability Soil3. Desertification- Make fertile areas into desertsWater Pollution1. Biomagnification- When concentration of toxins increase at highertrophic levels.
5 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.
6 Impact on Environmental Systems / Sustainability Air Pollution2. Acid Rain- Rain containing nitric & sulfuric acids3. Greenhouse Effect- Burning of fossil fuels & forests releasing carbon dioxide into the air, a greenhouse gas.
8 Impact of Renewable & Nonrenewable Resources - Provide a healthier ecosystem- Can’t be used up- Provided by environmentNonrenewable Resources- Damages environment- May lead to crisis- Only a certain amount left
9 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.
