Global warming is one of the most pressing environmental issues today. Cars and factories release large amounts of greenhouse gasses into the atmosphere each year. These gasses trap heat and make our atmosphere warmer and warmer. If we do nothing about it right now, we will suffer growing consequences such as floods and droughts, and vast coastal areas will be under water.

Plastic pollution is becoming a harmful environmental problem. Plastic products, such as bags, containers, boxes, etc. have brought convenience to our life, but they have also brought disastrous problems to our environment. As it is difficult to dispose of plastic wastes, they will pile up on the earth for tens, or even hundreds of years. Besides, plastics are the cause of many deaths of animals and fish because they mistake them for food. We must find a solution to plastic pollution before our earth is covered with plastics.
