a. Explain the problem

- Environmental pollution is one of the hottest global problems of humankind, namely, the presence of toxins and harmful substances that lead to rapid changes and bad effects on human life. . The sea is a part of the environment, marine pollution is the existence of many harmful substances in the marine environment that prevent marine creatures from living and create bad problems for humans.

b. Reality

- Currently, the mass death of fish in all provinces from Ha Tinh, Quang Binh, Quang Tri every day is more complicated. The cause has not been officially publicized in the public opinion, so the confusion of society is increasing gradually.

Quote

- Abnormal dead fish was discovered in early April in Ha Tinh, spread to Hon La (Quang Binh, bordered by Ha Tinh) and then expanded into the waters of Nhat Le, Hai Ninh and Le Thuy. On April 18 and 19, Quang Tri and Hue also appeared in this situation.

- Particularly in Quang Tri, the total amount of dead fish recovered by farmers is from 2 to 4 tons.

Every day, tons of waste is dumped into the sea, toxic substances accumulate more and more and negatively affect the environment and marine life.

- 10 tons of waste "hits" Nha Trang Bay every day.

- In the past few days, the coast of Ha Tinh province has witnessed two incidents where the main factor comes from environmental pollution along the coast. From March 2 to March 2, more than 50 hectares of commercial clams on the coastal beaches of Ky Anh and Cam Xuyen districts died up to nearly 90% without remedial measures, right after that the cockles and snails died naturally. The waves flooded the sandy shore of Ky Anh district, it could not be cleaned.
