Investigation

Introduction:

This project is to try  to convince  people to save our planet by explaining the main problem of global warming and how they  can help to save our planet. I think that all the population over the world is  involved  because of industrialization and the way of life we have today. What I will like to do is to aware people about this problem and to help them understand that if we don’t do something for it , in the future ours lives will be in danger!

What is Global warming?

Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth surface but trapping the heat as it radiates back into space. As the green house gases built up in the atmosphere the earth get hotter.

What is the green house effect?

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.

The Earth’s atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.

 

The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals

What can be done ?

It is important to slow down the warming as much as possible. This means using less fossils fuels, eliminating CFCs altogether and slowing down deforestation. This examples are much more useful in places were industralization is the main cause of global warming, but we can also help, by doing a series of things:

Join now!
  1. Turn off lights.
  2. Turn off other electric things, like TVs, stereos, and radios when not in use.
  3. Use rechargable batteries.
  4. Do things manually instead of electrically, like open cans by hand.
  5. Use fans instead of air conditioners.
  6. In winter, wear a sweater instead of turning up your thermostat.
  7. Insulate your home so you won't be cold in winter.
  8. Use less hot water.
  9. Whenever possible, use a bus or subway, or ride your bike or walk.
  10. Try to buy organic fruits and vegetables if you're concerned about pesticides. (Organic food ...
