Seas and oceans are an extremely important source of life and survival space for humans and the basic foundation for sustainable development. However, currently the seas and oceans are facing many serious problems, especially the problem of marine environmental pollution.
Plastic waste not only pollutes the environment
About 100 million tons of plastic items are created every year, and 10% of them end up in the ocean. They include fishing hooks, pieces of fishing nets, even plastic car engine covers... coming from many sources such as drifting from cities, landfills, and in containers that fall off ships during strong storms.
In water, small pieces of trash gather into larger blocks, which are swept by ocean currents closer to the coast - where many animals live. There, aquatic animals, birds and fish often mistakenly swallow plastic waste because they accidentally mistake it for food and swallow it. As a result, they can die due to blockage of the digestive system, or more broadly, exposure to toxins contained in plastic.
Although garbage does not cause immediate death, this is a warning about marine pollution as well as alarming environmental pollution.
Noise pollution is pushing many marine animals to extinction
Pollution does not necessarily have to be tangible. Sound created from ships, ultrasound equipment, and oil rigs can spread for kilometers. They disrupt the migration, communication, hunting, and reproductive activities of many marine animals.
The simultaneous deaths of hundreds of dolphins or whales have been attributed to the effects of extreme noise pollution, and many of them are on the brink of extinction.
Agricultural chemicals are the source of “red tides
Chemical residues from agricultural activities will seep into streams, rivers, groundwater... and then flow into the sea. If sea creatures eat it, they die en masse.

Oil and gas exploration and exploitation activities cause sound wave disturbance
The extremely loud noises created during gas and oil exploration are the most destructive, because they disturb the sound waves of marine life, causing them to lose the ability to find food, become stressed, and even become "lost". way" drifted to shore.
Garbage from cruise ships
Due to legal protections, cruise ships around the world operate with almost no environmental protection regulations and as a result cause much damage to the lives of sensitive aquatic species. have a cold.
Cruise ships dump about 1 million liters of wastewater into the environment every day
Need to act today
At the World Economic Forum on January 19, according to experts, the only solution to avoid the above disaster is to apply recycling initiatives. That means encouraging people around the world to collect and recycle plastic waste, use recycled packaging, and encouraging countries to significantly improve waste collection infrastructure to avoid the possibility of waste. Plastic leaks into nature.
