Global Warmth
In these years, Global Warmth has been a serious issue around the world. Many scientists has raised different opinions and solutions , but No one could have the exact answer for this question. The cause of Global Warmth is said related to CO2 and a hole on the sky. What could we do to better our planet.
A scientist suggested that turning off air conditioning was not enough. it only reduce the output of CO2 but still make the situation worse if we do not reduce the CO2, which already exists. For short, we have to reduce more CO2 than the output. The scientist said plants, stone , soil and sea could absorb CO2 but took a long time to do it. One way we can do is not only turning off air conditioning but also plant more trees, keep our sea clean and reserve the nature as much as we can.
Some scientists said there must be some way to fill the hole on the sky to protect earth from exposing to the sunshine directly. They tried to use chemicals sprayed on the sky but did not have much success.
Global Warmth is a disaster from human beings. We try to build a convenient environment for ourself and sacrifice the nature. Now, we have to pay for it and hope that it is not too late!
