1. Global Warming
It increases in the average temperature of Earth's surface.
It is caused by the gases produced (CO2) when humans burn coal, oil, etc. It affects the weather, natural resources, the health of people and animals around the world. The effects: increasing temperature, rising oceans, decreasing food and water, human health, economic. 2. Ozone Depletion
Ozone layer is a sun block around the earth.
Ozone reduces the amount of UV-B radiation that is harmful human health. It is thinner because there are lot of CFCs, Cl2, and pollution into the air. We prevent by many ways like forestation, Use of eco- friendly products, saving energy, public awareness about the dangerous effects. 3. Kyoto failed because there weren’t able to bridge the gap between developed and developing nations. The developed countries want to limit using non renewable resources that are harmful for environment but the developing still use them for economic benefit. Global warming effect than ozone depletion: By effecting on weather and human, global warming will accelerate ozone destruction. It makes the ozone depletion gets worse where the ozone layer becomes colder. 4. Indoor pollution: People spend most time indoor
Indoor air pollutants can cause discomfort, and reduce attendance and productivity. Sources: dust in air conditioner, dirty carpets, wall paints, cleaning products Solution: clean air conditioner, change new carpets, select wall paper, and wash carefully cleaning products. 5. Compare and Contrast Nuclear and Geothermal energy:
Geothermal energy is available energy in nature but nuclear energy has to produce. Both of two energies are harmful to environment, but nuclear energy affects more serious. Both are the good long term investment for large supply.
6. 3 main methods of waste disposal:
Landfill Get rid of trash take lot of land space
Be reused for other toxic waste
Capture methane gas pollution for air, water
