Extent of global warming
- Prolonged droughts in Africa and Asia
- Only 2 out of 6 glaciers are left in the Venezuelan Andes today
- 50% of the glaciers in the Glacier National Park (USA) no longer exist
- 20,000 people have died in Europe in 2003 due to the heat wave
-> global average temperature is expected to increase by about 4°C by 2100 if greenhouse gas emissions are not reduced

Save our Earth

Here are some out of the many things you can do to save our Earth
REDUCE GARBAGE
1. Precycle--buy things in packages that can be recycled or are made of materials that have already been recycled.
2. Wash, reuse, and recycle glass bottles and jars in the kitchen.
3. Instead of using paper towels, keep a cloth towel by the sink and use it to dry your hands or wipe up spills.
4. Reuse plastic bags. Wash them when they're dirty.
5. Recycle paper and cardboard items like empty cereal boxes, notepaper? newspapers, and magazines.
6. Use a lunchbox instead of a paper or plastic bag to bring your lunch to school.
7. Avoid using Styrofoam: it can't be recycled and is dangerous to animals if they eat it.
8. Donate old clothes, books, and toys to places like your local hospital, library, or Salvation Army.
9. Don't throw away cans of oil, paint, or gasoline. Save them for special garbage pickups called "toxic waste collections."
CUT BACK ON ENERGY
10 Turn out the lights when you leave a room.
11. Put on a sweater instead of training up the thermostat.
12. The next time you need to go somewhere, think twice before you ask for a ride. Walk or ride your bike whenever possible.
13. Open the fridge when you've decided what you want to eat--not while you decide.
14.Check the temperature in your fridge: it should be set between 38 [degrees]-42 [degrees] F. Any colder: it freezes food and wastes electricity.

Greenhouse Effect
Effects of global warming:
-> melting of ice/rise in sea level
- increased flooding and erosion
- loss of low-lying land to sea
- threat to aquatic life
Pollution
Industrialization has been the hallmark of human progress. However, with industries, have come a host of toxic gases that are being released into the atmosphere. The industries release gallons of liquid waste into the seas and rivers. Besides adding to air pollution, the innumerable vehicles running on the roads add to noise pollution that has lead to increase in stress, anxiety and problems related to hearing. Pollution of water has led to the decrease in a number of large number aquatic life forms. Respiratory diseases in human beings is the price we are paying for polluting the environment.
