Global Warming

( http://voicethread.com/share/90740/ )

Global warming is the increase in the average temperature of the Earth. But Is global warming bad? ummm, some global warming is good. But if extra greenhouse gases are made, the thermal blanket gets thicker and too much heat is kept in the earth's atmosphere. That's when global warming's bad. In addition, Extra greenhouse gases are produced through activities which release carbon dioxide, methane, nitrous oxide and ozone CFCs (chlorofluorocarbons). These activities include: - Burning coal and petrol, known as 'fossil fuels'.

- Cutting down of rainforests and other forests

- Animal waste which lets off methane

Moreover, let's us ask our self what could happen, If Earth gets hotter:

- Water expands when it's heated and oceans absorb more heat than land, so sea levels would rise.

- Sea levels would also rise due to the melting of the glaciers and sea ice.

- Cities on coasts would flood.

- Places that usually get lots of rain and snowfall might get hotter and drier.

- Lakes and rivers could dry up.

- There would be more droughts making hard to grow crops.

- Less water would be available for drinking, showers and swimming pools.

- Some plants and animals might become extinct because of the heat.

- Hurricanes, tornadoes and other storms which are caused by changes in heat and water evaporation may get more common.

To sum up, all this issue is happing because humans activities, without thinking about the result or the futur of the Earth, just what they asking easy and good life.

So, what did you think a bout Global warming?

Are you agree with me this issue is happen cuz humans activities? (!__!)
