In many parts of the world, water sources are increasingly polluted. Their consequences are truly formidable. The use of disposable plastic bags in Southeast Asia is now very popular. A 2017 report by the Ocean Conservancy (USA) found that China, Indonesia, the Philippines, Thailand and Vietnam dump more plastic in the oceans than the world combined. Marine biologist Darrell Blatchley said that over the past 10 years, the number of whales and dolphins that have died from eating trash and plastic has increased. This is the case of the whale swallowing the largest amount of trash ever recorded. Last June, a whale in southern Thailand also died after swallowing more than 80 plastic bags. We must propagate, educate, and create conditions for businesses to overcome by measures such as funding support from the environmental protection fund, support for relocating establishments to remind about jobs. of employees, helping businesses maintain and develop production and business. Therefore, the treatment of environmental pollution is not only the task of the natural resources and the environment, but also of the political system and the whole society so that the living environment of Vietnamese people is constantly green, clean, and beautiful ... are urgent requirements to respond to the World Environment Day on June 5 every year.
