As the world is developing day by day, greenhouse effect becomes more and more serious. Greenhouse emissions from the developed countries and the fast-growing countries, have the responsibilities to cut down the effect of climate change.
To show a more significant result, we need the comparisons of different countries like the United Nations climate meeting. They can share their ideas and do some exchange on their results. If different countries have their own measures to deal with the problems, we will never succeed. Although there are some conflicts between the USA and other countries, they are still paired up to take the responsibilities and lead other less-developed to solve the problems. Many people are happy to see that different countries finally agreed to cooperate.
It's definitely not an easy task for all countries in the world to save the world, but if we, every citizen on the world plays our own role, be self-discipline, it's no longer a difficult task.
