whassupwidis blog man? Well the least i can say is global warming is caused by pollution - mainly air pollution. some gases like carbon monoxide,CO, tend to warm up our planet casuing many problems to us! for example, the melting of the icecapes in the anatartica has increased the tides and water level in our world. its because of this that floodings occur. Not onli dat, the depletion of the ozone layer also layer also plays a part in global warming. our earth is protected by an atmospheric layer which helps prevent harmful rays from entering the earth. this is called the ozone layer. due to this depletion of the ozone layer, ultraviolet rays from the sun ten to hit the earth surface easier. this excess amount of ultraviolet rays would damage the humans skin - skin cancer for example is partly caused by global warming. All these factors play a part in global warming. the percantage of our greenhouse gases are reducing due to these unwanted gases. if carbon monoxide is breathed in, it can damage our lungs and dirty our bloodstream. but main reason for global warming is actually US! due to the excess usage of natural resources like the buring of petrol,crude oil and other fossil fuels, the by-product carbon monoxide is given out. the world is doing as much as possible to reduce this excess release of carbon monoxide which is actually the main factor for global warming.so...dats bout it la i guess. very little rit? I KNOW
