Global warming is one the most series challenges facing us today.To protect the health and economic well being of current and future generations,we must reduce our emissions of heat trapping gases by using the technology,know-how,and practical solutions alreadyat our disposal.
Tropical deforestation is the largest source of emissions for many developing countries,but slowing deforestation can’t solve the climate problem by itself.for years we have heard so much about the causes of climate change,that we’ve missed the fact that there are simple,practical solutions that can slow this growing problem.Thecnologies exist today that can cut emissions of heat-trapping gases and make a real difference in the health of our planet.and this solutions will be good for economy,reduce our dependence on foreign oil,and enhance our energy security.Global warming doesn’t just mean balmy February days in northern climes.it also means increasingly hot days in the summer ,and a host of negative impacts that are already under way and are expected to intensify in the coming decades.
· More heat waves will likely increase the risk of heat related illnesses and deaths.
· Cities and towns along the nation’s major rivers will experience more severe and frequent flooding.
· Some areas will likely experience more extensive and prolonged droughts.
The solutions to climate chanige are here and it’s time we put them to us.if we get started today we can tackle this problem and decrease the unpleasant outcomes that await us if we do nothing.
The scientific consensus is in.our planet is warming ,and we are helping make it happen by adding more heat trapping gases, primarily carbon dioxide (co2),to the atmosphere.the burning of fossil fuel (oil,coal and natural gas) alone accounts for about 75 percents of annuel CO2 emissions from human activities. Deforestation the cutting and burning of forest that trap and store carbon accounts for about another 20 percent.
Procrestination is not an option. Scientists agree that if we wait 10,20,or 50 years,the problem will be much more difficult to address and the consequences for us will be that much more serious.our atmosphere has limits too.CO2 remains in the atmosphere for about 100 years. The longer we keep polluting, the longer it will take to ricover and irreversible damage will be done.
That all my speech,if I have many mistakes please for give me. Thank you very much.
