Study Notes
Environmental Issues
- Improper disposal of waste leads to contamination of soil, taking millions of years to recover
- Hazardous waste in dump or landfill can pollute the soil
Overpopulation
- Overpopulation occurs when there are too many people and not enough resources
- Results in shortage of water, food, and natural resources
- Leads to increased pollution, further polluting the earth
Deforestation
- Loss of trees leads to decrease in oxygen production, necessary for human survival
- Causes many animals to become endangered or extinct
- Humans are the leading cause of deforestation, mainly for farming or building
Ocean Pollution
- Chemicals poured into ocean create dead zones, killing marine life
- Dead zones lead to loss of biodiversity
- Similar to deforestation, ocean pollution causes loss of living organisms
Water & Air Pollution
- Chemicals in freshwater sources contaminate water, making it undrinkable
- Over 1 billion people lack access to clean drinking water
- Ozone layer depletion allows UV rays to pass through, causing global warming
- EPA refers to ozone layer as "Earth's sunscreen"
- Greenhouse gases from cars and human activities contribute to ozone layer depletion
Solutions
- Recycling can help reduce land pollution and garbage
- Conserving water by shutting off taps, taking shorter showers, and using rain barrels can help
- Reducing air pollution by riding bikes, carpooling, and reducing exhaust fumes can improve air quality
