With the development of economy,more and more greenhouse gases are being discharged into the air.CO2 makes up about 70% of the greenhouse gases,which is considered to be one of the greatest causes of global warming.It has harmful effects,causingthe sea level to rise and many natural disastersto strike.
So we must take effective measures to save our planet.FMy suggested answer:

Global warming is a growing problem in the world. Melting ice-caps in the Artics and Antartica, rising temperatures across the continents, increasing number of typhoons and tropical storms are just some of the effects of global warming.

It must be realised that humans activities are the causes of global warming. The increasing levels of carbon dioxide (CO2) have rose at exponential rates. It is therefore our duty to save the earth.

The task can be divided into a few levels: Individual level, national level and international level.

Starting from the individual level, we can begin by minimising the amount of carbon dioxide by taking public transport instead of driving and using energy-efficient electrical appliances.

At the national level, the government can probably limit the number of cars allowed on the roads by imposing fines on offenders and improving public transport systems. More trees can be planted too. Education to protect the environment should also be planned.

At the international level, countries around the world can hold meetings and conferences and decide the steps to take to limit the CO2 levels. Economic sanctions can also be imposed on countries that have violated the rules. The Kyoto Protocol is one such example.

It is important to cure the world, for the sake of ourselves and our descendants. We have to take action now.
