1.) Carbon dioxide is undoubtedly, the most important greenhouse gas in the atmosphere.<br />
Changes in l<strong>and</strong> use pattern, deforestation, burning fossil fuels, Power Plants, use of fertilizer<br />
in agriculture <strong>and</strong> other activities have all led to a rise in the emission of carbon dioxide.<br />
At first we want to talk about burning fossil fuels.<br />
a) Burning fossil fuels<br />
When fossil fuels like coal, oil <strong>and</strong> gas are burned, they release greenhouse gases. In 2005,<br />
burning fossil fuels sent about 27 billion tons of carbon dioxide into the atmosphere.<br />
People burn fossil fuels to create energy, which is used for many things including:<br />
� heating homes <strong>and</strong> buildings<br />
� growing, transporting <strong>and</strong> cooking food<br />
� travelling (for example, by car, plane, bus <strong>and</strong> train)<br />
� treating water to make it drinkable, heating it <strong>and</strong> piping it into homes<br />
� manufacturing, using <strong>and</strong> transporting products, from clothes to fridges, from plastic<br />
bags to batteries<br />
b) Deforestation<br />
Cutting down forests faster than they are replaced (deforestation) is a major contributor to<br />
climate change. It accounts for about 20 per cent of human carbon emissions – more than the<br />
entire global transport sector produces.<br />
Deforestation makes such a huge contribution to carbon emissions because trees absorb CO2<br />
as they grow. <strong>The</strong> more trees that are cut down, the fewer there will be left to absorb CO2,<br />
leading to it building up in the atmosphere.<br />
