(The World is presently facing a crisis called Global Warming. Global Warming is the result of increased Greenhouse Effect in the atmosphere due to numerous human activities.)
Have you noticed that the climate has been getting warmer and warmer in recent years, the place which used to be land now is covered by water, the birds which sings on your head now becomes less and less. Nearly all scientists agree that the planet is warming. What is still open for debate is how much of the warming is due to human activites, and what all the potential effects will be worldwide. The Pentagon commissioned a report on the possibility of rapid climate change-in particular examining the collapse of the north atlantic thermohaline conveyor (a process that delivers warmth from the gulf stream to Europe).
In terms of what we can do, everyone can work to reduce carbon emissions. But we need to realize that such a fix will not stop warming for quite some time. Current models show that even with a complete halt to human based carbon emissions, that the world would not stop warming for decades. This same lag effect has made it difficult for scientists to finally agree that long term warming was taking place. Now we have enough data to be pretty sure on that, but we don't have many solutions as how to significantly slow the warming.
Ultimately, it would be ideal for the human race to move toward energy and economic growth solutions that would sustainable in the long long term (centuries or more)... To reach that state we need to move entirely to renewable energy sources and close the loop on materials and toxics used in manufacturing. This will probably take at least 50-100 years, but we'll never get there unless we start... and not getting there is not really an option for the human race as a whole.
Cars and trucks are another significant source (25 percent) of carbon dioxide emissions. A serious effort to address global warming must therefore reduce emissions from cars and trucks. Many technologies already exist that can do this, while also creating new jobs in automotive sector and other industries throughout the country. In addition, Chinese consumers would save billions of dollars on gasoline, and we would reduce our dependence on foreign oil.
Scientists tell us that because of air pollution, the earth's heat can't escape which makes the environment hotter and hotter. And if we don't stop this situation, it will cause many tragedies in the future, we can't wait any more, but take action from ourself first, to fight for our next generation.
