Marine plastic pollution
Decades of years ago, plastic came to people's daily life and brought a lot of convenience to people. Meanwhile, people overuse plastic in their daily life, leaving large amounts of waste. Due to lack of strict waste-collection systems, plastic waste enters rivers and oceans, causing
pollution.
It is estimated that marine plastic kills millions of animals every year. And it is reported that nearly 700 species have been affected by it.
It's time we took some measures to deal with the problem. First, we must limit the use of plastic products in our daily life.Second, alternative materials should take the place of
plastic. Third,plastic waste should be managed effectively. It's mankind's responsibility to find solutions that are good for us and our future generations.
