Marine debris not only causes visual pollution, but also water pollution and deteriorates water quality.
The biggest plastic waste in the ocean is discarded fishing nets, some of which are several kilometers long and are called “ghost nets” by fishermen. Under the action of ocean currents, these fishing nets intertwine and become “death traps” for marine mammals. They entangle and drown thousands of seals, sea lions and dolphins every year. Other marine organisms tend to mistakenly swallow certain plastic products for food. For example, sea turtles particularly like to eat plastic bags that look like jellyfish; things are vomited up to feed young birds, weak young birds often die of suffocation. Plastic products cannot be digested and broken down in the body of animaux. If consumed by mistake, they can cause stomach upset, abnormal movements, reduced fertility and reproduction, and even death. The death of marine life ultimately leads to disruption of marine ecosystems.
Plastic waste can also threaten navigation safety. Plastic waste can get tangled in ship propellers, especially various plastic bottles called “magic bottles.” They can damage ship hulls and machinery, cause accidents and shutdowns and cause heavy losses to shipping companies.
The blue waters, white sandy beaches and good ecology of the vast South China Sea are heartbreaking. However, marine debris such as fast food boxes, plastic bags and fishing nets float on the sea from time to time, polluting the beautiful South China Sea.
The oThe organization "Greenpeace" found that at least 267 species of marine life suffered from the ingestion of marine debris or became entangled in marine debris, resulting in their death, which is fatal to marine life. Additionally, marine litter can harm humans through the biological chain. For example, heavy metals and toxic chemicals can accumulate in the body when ingesting fish. Consumption of these fish will inevitably pose a threat to human health.
Human coastal activities and recreational activities, shipping, fishing and other maritime activities are the main sources of litter on beaches. According to statistics, plastic and polystyrene products account for 90% of floating trash in the ocean.
Experts say marine debris is devouring the oceans on which humans and other creatures depend. If no action is taken, the ocean will not be able tosupport its load and humans and other creatures will not be able to survive.
To this end, experts strongly call on the public to become more aware of protecting the marine environment, refrain from dumping waste into the ocean at will, and reduce the amount of marine waste at source to reduce impact. of marine litter on the marine ecological environment. Protect our “blue house”.
