About the early 20th century, my country's economy was at a time of vigorous development and the glorious rise of major industries. The prosperity at that time was the era that was most talked about after 70 years and 80 years later. But at that time, people's environmental protection concepts were not prosperous, they had no relevant knowledge and abundant experience. Therefore, in addition to the unscrupulous discharge of waste gas and sewage, even the waste from many manufacturing and traditional industries was often invisible and evaded.
Many unwritten "tactic understanding" allows shoe manufacturers, clothing factories, textile industries, electronic factories and other industries to dump the waste and eliminated inferior products directly into the river. These garbage will eventually merge into the vast Yangtze River , Yellow River , Heilongjiang, Pearl River , Liaohe , Haihe , Huaihe , Minjiang, Qiantang River , Lancang River and other tributaries. They will eventually spread to all parts of the world with the drift of the ocean currents.
Don’t think that this is fine, because humans hurt the earth, but every action will leave scars.
. Environmental protection regrets like the early years of our country actually happen in every corner of the world every day.
Pacific garbage belt : 16th of my country's land area
Such innocent fish, seabirds, sea turtles , and mammals have become victims of selfish scrutiny. Perhaps they are ingested by mistake, may be entangled, and may even lead to sudden death due to infection. In addition to the countless drifting garbage you and I can clearly see on the beach, there are actually terrible "garbage islands" that you don't know on the sea...
According to a research report published by scientists in a journal, garbage islands called "Pacific Garbage Patch" have been increasing and expanding in recent years. These garbage that drives drifting and finally stationary in the subtropical high-pressure zone have accumulated over the years and have become exaggerated "cloud-like" vortexes, extending from the coast of California to Hawaii, spanning 1.6 million square kilometers in size, which is three times that of French territory, and about one-sixth of my country's land area.
Such a continuous extension of garbage belt is the most exaggerated gathering area for plastics in the ocean on Earth. Through a three-year survey, scientists said, "There are at least 1.8 million plastic waste in the area, with a total weight of more than 9 million metric tons, and the situation has been deteriorating again."
The "masterpiece" of human beings is flooded on the island of
In order to analyze how large the Pacific garbage belt spans, the research team conducted comprehensive sampling work, and at the same time, 30 ships directly entered the plastic area to explore, collecting some garbage by collecting some garbage; in the air, there were several flight missions, scanning the ocean surface of more than 300 square kilometers in the air.
On these stretching "garbage islands", experts found that 92% of the mass is mainly composed of larger objects, such as plastic waste, computer case, tire, mobile phone, shoes, clothes, plastic bottles, plastic bags, etc. accumulated; 8% of the mass is plastic particles, which are plastic debris produced under the exposure of the sun and the erosion of sea water - it is very easy to be swallowed by marine organisms .
. Since the observation of the Pacific garbage belt in the 1970s, the rate of garbage increase has not decreased. The amount of people discarded is much higher than that of nature that can naturally decompose, and has grown by nearly 16 times.
2050 plastic waste may be more than fish
Environmental protection groups have also found that 300 million tons of plastic are produced every year around the world, of which 5 million to 13 million tons of plastic waste debris are dispersed into the ocean and are then ingested by seabirds, fish and other organisms.
What’s terrible is that by 2050, the weight of plastic in the sea will be heavier than the weight of fish. As the food chain continues to accumulate, it is the humans who finally eat these plastics into their stomachs.
Scientists have also recently estimated that people who eat seafood will consume about 11,000 more plastic fragments every year; among all fish caught in the UK, more than one-third of the fish species contain plastic, including cod , salmon and shellfish. Researchers stress that recycling does not prevent the environmental impact of plastic waste, it only delays entry into landfills or natural environments.
In marine garbage, the most common thing to find is plastic bottles, and plastic bottles are also the main culprit of human infringement on the earth. Experts estimate that by 2021, the annual consumption of plastic bottles will reach 50 trillion bottles, far exceeding the number that can be achieved by recycling.
The terrible fact is: a total of 1 million plastic bottles are purchased every minute around the world, and this number will increase by another 20% in 4 years, and environmental protection issues are at stake. Experts also estimate that the severity is no less than that of the disaster of climate change.
first understand the problem and then solve the problem
research team emphasized, "In order to solve the problem, we think it is crucial to understand it first. These results provide key data to develop and test our cleaning technology. The research highlights the urgency of dealing with the plastic pollution problem. If it is so uncontrollable, we may never have a day to recover."
They said that they are planning a "floating wall of oil cables" that can be blocked, intercepting the area where the ocean current is painted, so that the garbage will not float to the windless belt again. This is the most effective way to deal with the garbage before it is decomposed into plastic debris. However, considering the overall scale and severity of garbage, this challenge is huge.
