  Nowaday, our environment are becoming more and more polluted. But in my opinion, water pollution is one of the most terrible pollution in the world. So what is water pollution? Water pollution is the pollution of water, such as trash in lakes, rivers, seas, the oceans or even groundwater. Not only that, it also is a problem for the species and ecosystems because it affects plants and organisms living in the water. There is wastewater from factories a lot and maybe this is one of the biggest problem of pollution of water.

Where I live, Hanoi's main natural problems are water contamination, air contamination, and contamination by disturbances. Pollution makes people here less healthy, and some even know the harmful effects of dangerous diseases. Eliminating the use of vehicles is the most ideal approach to reduce air contamination and clamor contamination. I believe that the best arrangement is to bring issues to light and teach people to ensure the climate. Therefore, the public authority should deal with this issue immediately.
