• List examples of biomes in Vietnam that are being changed by humans:

First, the Vietnamese government established the Environmental Law at the end of the 1993 which helped establish initiatives. These initiatives are helping to make the large population aware of environment, as well as teaching how to help the environment recover. These include replanting programs and slowing the land use cycle. Second, the problem is that many people throw plastic bags into the sea and the fish will eat the plastic. This not only pollutes the environment, but can kill the fish.She says it is a tradition for Vietnamese to release three fish seven days before the start of the Tet - the Lunar New Year. She says the fish are the Kitchen God, spirit that live in the home of every family. The problem is that many people release both the fish and the plastic bag they came in. The Carp Team's solution is to lower fish down to waterside so they can released there. The team also collects the plastic so it can be reused. Third, air pollution is a major concern for families in the big cities. Finally,  Deforestation is a major issue faced by Vietnam. Deforestation has had a major, yet negative effect on the environment, with native animals and flora becoming extinct.
