Global Warming

Every one should realize about Global Warming.Because our world is going in a bad condition.So we have to realize the importance of that. The sun is getting hotter. It is also incredibly old about 5000 million years old. One day it will blow up but that won't be for another 5000 million years or so. But the Earth's climate seems to be heating up much much faster than can be explained by the sun making more heat. And the reason seems to be people and machines.The single largest problem posed by global warming would be if the seas rose and increasingly inundated Bangladesh, an extremely densely populated and low-lying region long vulnerable .

One obvious way to mitigate this vulnerability would be to increasingly encourage Bangladeshis to use birth control.people are burning fuels with carbon in (that's oil, gas and coal which you use in cars, aeroplanes, power stations and so on), all this carbon gets dumped into the air, mixed with the oxygen we all breathe, and so adds to our greenhouse gas problem. And the planet warms some more.A recent study of nearly 2,000 species of plants and animals discovered movement toward the poles at an average rate of 3.8 miles per decade. Similarly, the study found species in alpine areas to be moving vertically at a rate of 20 feet per decade in the 2nd half of the 20th century.The ocean will continue to become more acidic due to carbon dioxide emissions. Because of this acidification, species with hard calcium carbonate shells are vulnerable, as are coral reefs, which are vital to ocean ecosystems. Scientists predict that a 3.6 degree Fahrenheit increase in temperature would wipe out 97 percent of the world's coral reefs.

Diseases

Then there's disease. As the world warms, nasty diseases like malaria are starting to spread because the changing climate favors the mosquito that carries the disease. Air travel is not just a cause of global warming and aids in spreading diseases very quickly just about anywhere. Someone with an illness like TB may easily pass on the disease to others during an airplane flight of a few hours. Insects like mosquitoes which can carry disease can even 'hitch a ride' on flights from one country to another.

People who study earth's climate have found that as it warms up, the weather is going to get more violent and unpredictable. Hurricanes, for example, will become more powerful. Deserts are increasing and rain will be heavier in parts of the world so there will be more floods. These things have already started to happen. What can you do to stop it?Get active, why drive when you can walk?! If your family has a car, get them to use it less. Walk to the shops. Walking, running, skipping are all much more fun.
