Do you know the polluted environment we live in is created by us? Vietnam is one of the most polluted countries in the world due to the low awareness of the Vietnamese people. This always leads to serious consequences due to environmental pollution. Vietnam has propagated a lot of measures to prevent environmental pollution. We can start with simple things like putting waste in the right place, not smoking in the public area or do not destroy trees. Please pick up trash if you see them on the street. Turn off the light if you go out. Recycle, reuse and reduce plastic bottles, plastic bags.... We need plant many trees and we shouldn't cut down trees. We should save water and don't use too much if you don't need or we can ride a bike to reduce the amount of smoke. Let save the planet for you and me!
