What's the Big Deal with Global Warming?


It was reported that Earth has warmed by about 1 degree Fahrenheit in the past 100 years and scientists expect an additional increase of 2 degrees to 6 degrees Fahrenheit in the next century. You've guessed it wight. It's the global warming. So what's the big deal?

Let's define global warming first. According to the United States Environmental Protection Agency, global warming refers to the average increase in the Earth's temperature. Greenhouse gases (water vapor, carbon dioxide, nitrous oxide and methane) trap the energy from the Sun, preventing heat from e
scaping back into space. Without the greenhouse gases, Earth would be too cold for humans to survive.

But it's the rate of global warming that worries the scientists and environmentalists because of industrialization, more greenhouse gases are released in the a
tmosphere, resulting in rise in global temperature. This, in turn, leads to climate change. Indeed, climate changes all over the world have been recorded. There are heat waves and periods of unusually warm weather, ocean warming, rise in sea level and coastal flooding, melting of glaciers and Arctic and Antarctic warming.

Global warming can also upset the ecosystem. Living things which depend on the delicate balance of rainfall, temperature and soil will be in danger. With habitats destroyed, some animals and plants will cease to exist. With drought, people won't be able to plant crops.

BUT don't despair. It's not yet too late. Here are some things you can do to help.
  1. Plant trees.
  2. Recycle bottles, newspapers and tin cans.
  3. Reuse plastic shopping bags.
  4. Conserve energy. Turn off appliances when not in use.
  5. Inform others about global warming.
See. It's not difficult at all. If each and every one of us do our part, there's nothing to worry about.=)
