Task 2


An Introduction to Global Warming

Global warming is the most severe problem that we are facing today. It affects people, animals, culture and weather. There is no doubt in my mind that global warming is one of the greatest threats facing humanity. This essay will discuss the causes and solutions of global warming.
Starting with causes, one of the greatest problems caused by global warming is when the sea level rises; the water covers many low lying islands. This is a big problem for many of the plants, animals, and people on islands. A second cause is electrical pollution. Every kilowatt-hour of electricity saved keeps 1.5 to 2 pounds of CO2 out of the atmosphere. Another cause is when people cut down trees. Trees and other plants collect carbon dioxide (CO2), which is a greenhouse gas. Burning carbon-containing fossil fuel produces carbon dioxide.


Turning to solutions, one is to use bus, bike or to walk as an alternative of using car a daily basis. This will reduce the percentage of pollution, because cars release a lot of greenhouse gases into the air. Another way in which we can reduce global warming is to plant trees, because trees absorb carbon dioxide from the air. A final workable solution is to recycle things like cans, bottles, plastics and papers. By recycling companies use fewer raw materials to create new products.
In my opinion, the most of the warming observed over the last 50 years is attributable to human causes.
My suggestion is that we should move towards the most effective possible steps to reduce carbon loading of the atmosphere and to do it urgently.

    We have to find any way to reduce the pollution and anything causes the global warming.

  2. Well you are truely right about whts happening and the solution for it is to use bus and bikes for transportation but not everyone likes to transport with bikes and buses especially rich countries.. i hope this problem can be solved.
