I think the most important issue on our planet now is polluting. Human pollutes environment and thereby kills the Earth. A lot of plastic waste are thrown away on the beaches. Every time a new plant is built, the planet's ecology worsens. This is popular problem in many countries and almost no one thinks how to solve it. People should to unite and decide what to do with this, otherwise the planet will continue to be littered with people and it will lead to more serious problems.
