choking the oceans - oil containment boom
The big garbage patch in the Pacific Ocean is expanding-there is only one way to make it smaller.
Plastic is everywhere in the world.
It's on our cars and carpets and we wrap it around the food we eat and almost all the other products we consume.
It has become a key lubricant for globalization-but it has killed our future in a way that most of us barely realize.
I just came back with a team of scientists from the sea for six weeks, study in the Great Pacific Garbage belt-this is the latitude of our land Desert, one of the five main garbage belts drifting north and south of the equator.
While this was my tenth voyage to the area, I was very shocked to see a sharp increase in the amount of plastic waste since my last trip in 2009.
A wide variety of plastics, from toothbrushes to tires, to illegible debris, floating hundreds of miles above our marine research ship Alguita
We even came across a floating island with dozens of plastic floats for oyster farming that you can walk on the island.
Plastic is now one of the most common contaminants in the world's marine waters.
Driven by wind, tides, and water flow, plastic particles, together with other debris, form a huge vortex-like viscous accumulation zone, which oceanologists call gyres, which accounts for 40% of the surface of the Earth's oceans, about 25% of the Earth.
No scientist, environmental activist, entrepreneur, national or international government agency is able to establish a comprehensive way to recycle the plastic waste that covers our land, which will inevitably scratch into the sea.
In a 2010 study I conducted on the Los Angeles and St. Gabriel River, we inferred about 2.
In just three days of sampling, 3 billion pieces of plastic-from polystyrene foam to tiny pieces and particles-flowed into coastal waters from the city center of Southern California.
There are many harmful consequences of human "plastic footprint", some are known, some are not yet discovered.
We know that the degradation of plastic is very slow and will break down into tiny pieces in a few centuries. long process.
We know that plastic debris will wrap around and slowly kill millions of marine life;
Hundreds of species mistake plastic for their natural food, consuming toxic substances, causing liver and stomach abnormalities in fish and birds, often choking or starving them.
We know that one of the main bait fish in the ocean, the lantern fish, eating a large amount of plastic debris threatens their future as a source of tuna, salmon nutritious food, and the other ocean fish we eat increases the amount of synthetic chemicals that we now carry in our bodies that were unknown before 1950.
We suspect that stray plastic waste kills more animals than climate change-a hypothesis that needs to be tested carefully.
On a recent voyage, we studied the effects of pollution, and when looking for invasive species and plastic, we took blood and liver samples from fish
Related contaminants that cause abnormal protein and hormones.
While we hope that our research will make an important contribution to scientific knowledge, they cover only a small part of the broader problem.
The reality is that only humans are prevented.
First, the debris generated from reaching the ocean-most of which are disposable plastics-will significantly reduce the plastic load of the ocean. Clean-
The Up plan is quite a bit, but has never been implemented at the garbage station.
No matter how complicated the technology is, the spenders and the doers will never be able to clean up the remote garbage cycle: the chaotic ocean is scattered and mixed too much.
We should use the oil purifier at the estuary, where there is a lot of stuff going into the ocean every day, but this is not a problem that can be compared to encircling huge fritters with a containment boom.
Aquaculture uses a large amount of plastic in its fish floats, nets, fish lines and fish tubes, making the problem more complex.
The most common floats and tubes I found on the deep sea and the Hawaiian beach come from the huge ocean --
Sea urchins and oyster farms like creating oysters-
The floating boat island we found
However, there is no regulatory remedy for accidental loss and the large amount of plastic equipment in the storm.
Despite dozens of pages of standards, government and industry organizations claim to certify sustainably farmed seafood without mentioning lost and floating equipment.
Government support for aquaculture that is properly concerned about the depletion of marine food sources should include funding for marking, monitoring and research in order to make all plastics used benign, if it's flooded by our precious ocean
But, in the end, the real challenge is to crack down on an economic model based on waste of products and packaging and leave relevant cleaning issuesup costs.
Changing the way we produce and consume plastics is more challenging than limiting the production of carbon dioxide.
Plastic recycling is a nightmare.
It's hard for them to clean.
They can melt at low temperatures, so impurities do not evaporate.
There is no difference between whether synthetic polymers like polyethylene come from oil or plants;
It is still a persistent pollutant.
Marine degradation plastics are present, but the manufacturer quickly noted that marine degradation does not mean "one-off oceans ".
Scientists in Britain and the Netherlands have proposed reducing plastic pollution through a "circular economy.
"The basic concept is that the product must use Terminal design. of-

Provide incentives to eliminate the possibility of products becoming waste.
In the United States, especially in California, the focus has been on
Known as structural control, for example, to cover ditches and catch pools with 5mm screens.
This reduces the amount of debris flowing from the river to the sea.
Activists around the world are lobbying to ban the use of the most polluted plastics-bottles, bags and containers that provide food and drinks.
Many people have succeeded.
In California, nearly 100 cities have passed a ban on garbage throwing.
The Senate is considering a state --wide ban.
Before we turn off the stray plastic faucet that flows to the sea, we will continue to play a game of hide and seek
The latest global threat to the human age we live in.
