3. Human Activities and Impact on the Environment
Greenhouse Effect-
Causes- by burning of fossil fuels and loss of forests increasing the amount of trapped atmospheric gases.
Possible Results- Changes in climate, melting of polar ice caps, drought and flooding

4. Acid Rain
Causes- Burning fossil fuels releases sulfur into the air making it more acidic.
Possible Results- acid rain can destroy forests, poison lakes and kill wildlife. It can also erode statues and buildings.

5. Ozone Depletion
Causes- Use of certain compounds like CFCs that destroy the ozone layer in the upper atmosphere. The ozone layer blocks UV rays from the Earth.
Possible Results- Higher cases of skin cancer and possible mutations in organisms.

6. Air Pollution
Causes- Burning fossil fuels, wood, releases chemicals into the air.
Possible results- Increase in breathing problems and illness in humans and other organisms

7. Water Pollution
Causes- Waste, trash, heat, chemicals etc. contaminating rivers, lakes and oceans.
Results- Threat to species that live in or near water, less clean water for drinking , farming etc.

8. Soil Depletion
Causes- Soil erosion, overuse of soil, and pesticides threaten the quality and quantity of soil.
Results- Threat to agriculture, organisms that live in soil.

9. Habitat Destruction
Causes- Poisoning of lakes, deforestation, urban development
Possible Results- Threatens or destroys the species habitat and upsets balance of nature
