Climate change is one of the most important issues that people face nowadays. There's an opinion that climate change cannot be reversed at all.

In my opinion, climate change is somehow a natural phenomenon. Millions of years ago, the earth went through many periods of climate change for example the Ice Age - the time when the whole earth was covered with ice. Therefore, climate change is almost a must-happen phenomenon.

On the other hand, people activities are factored that make climate change happens faster. Activities such as transportation, manufacturing... releases a lot of CO2 into the environment, leading to greenhouse effect and climate change. So that, the things that contribute to limiting carbon emission into the environment such as reducing plastic bags, recycling waste... will help slow down the climate change process and save human lives.
