Engineers are deploying a trash collection device. It is designed to corral plastic litter floating between California and Hawaii. This is an attempt to clean up the world's largest garbage patch. It is in the heart of the Pacific Ocean.

The 2,000-foot (600-meter) long floating boom is being towed from San Francisco to the Great Pacific Garbage Patch. The "patch" is an island of trash. It is twice the size of Texas.

The system was created by The Ocean Cleanup. It is an organization founded by Boyan Slat. He is a 24-year-old innovator from the Netherlands. He first became passionate about cleaning the oceans when he went scuba diving at age 16. In the Mediterranean Sea, he saw more plastic bags than fish.

"The plastic is really persistent. It doesn't go away by itself. The time to act is now," Slat said. He added that researchers with his organization found plastic going back to the 1960s and 1970s bobbing in the patch.

The buoyant, U-shaped barrier is made of plastic. It has a tapered 10-foot (3-meter) deep screen. It is intended to act like a coastline. It is designed to trap some of the 1.8 trillion pieces of plastic. Scientists estimate the pieces are swirling in that gyre, but they believe it is allowing marine life to safely swim beneath it.

The cleanup system is fitted with solar power lights, cameras, sensors and satellite antennas. It will communicate its position at all times. This will allow a support vessel to fish out the collected plastic every few months. Then it can transport it to dry land where it will be recycled, said Slat.

Shipping containers will be filled with the fishing nets, plastic bottles, laundry baskets and other plastic refuse. All will be scooped up by the system. It was deployed Saturday and is expected to be back on land within a year, he said.

Slat said he and his team will pay close attention to whether the system works efficiently. They want to know whether it withstands harsh ocean conditions, including huge waves. He said he's most looking forward to a ship loaded with plastic coming back to port.

"We still have to prove the technology. It will then allow us to scale up a fleet of systems," he said.

The Ocean Cleanup has raised $35 million in donations to fund the project. These include funds from Marc Benioff, chief executive of and from PayPal co-founder Peter Thiel. Ocean Cleanup will deploy 60 free-floating barriers in the Pacific Ocean by 2020.

"One of our goals is to remove 50 percent of the Great Pacific Garbage Patch in five years," Slat said.

The free-floating barriers are made to withstand harsh weather conditions and constant wear and tear. They will stay in the water for two decades and in that time collect 90 percent of the trash in the patch, he added.

George Leonard, chief scientist of the Ocean Conservancy, a nonprofit environmental advocacy group, said he's skeptical Slat can achieve that goal because even if plastic trash can be taken out of the ocean, a lot more is pouring in each year.

"We at the Ocean Conservancy are highly skeptical but we hope it works," he said. "The ocean needs all the help it can get."

Leonard said 9 million tons (8 million metric tons) of plastic waste enter the ocean annually and that a solution must include a multi-pronged approach. This includes stopping plastic from reaching the ocean and more education so people reduce consumption of single use plastic containers and bottles.

"If you don't stop plastics from flowing into the ocean, it will be a Sisyphean task," Leonard said, citing the Greek myth of a task never completed. He added that on September 15 about 1 million volunteers around the world will collect trash from beaches and waterways as part of the Ocean Conservancy's annual International Coastal Cleanup. Volunteers last year collected about 10,000 tons of plastics worldwide over two hours, he said.

Leonard also raised concerns that marine and wildlife could be entangled by the net that will hang below the surface. He said he hopes Slat's group is transparent with its data and shares information with the public about what happens with the first deployment.

"He has set a very large and lofty goal and we certainly hope it works but we really are not going to know until it is deployed," Leonard said. "We have to wait and see."

The system will act as a "big boat that stands still in the water" and will have a screen and not a net so that there is nothing for marine life to get entangled with. As an extra precautionary measure, a boat carrying experienced marine biologists will be deployed to make sure the device is not harming wildlife, Slat said.

"I'm the first to acknowledge this has never done before and that it is important to collect plastic on land and close the taps on plastic entering into the ocean, but I also think humanity can do more than one thing at a time to tackle this problem," Slat said.

    How this trash pile up is from the people that don't listen to the law or is that it went on accident.There could be more ways on how this could happen.It could be like from dump trucks,animals might even be from the moon.This could also kill animals in the ocean making them extinct from our world.This is why we need to clean up the oceans so animals in the ocean don't become extinct.

    According to the text, I think all of this trash accumulated because when there are storms on the ocean the plastic flies around and sticks to other plastic. So they keep sticking to each other and become a big lump. I think this because in the text it says the harsh weather conditions might break the barriers. Plastic is also really light so this could easily happen.

    So much trash can be accumulate by people stop putting trash in the ocean. People put trash in the ocean every day because they are to lazy or they just don't care about what will happen to the ocean and the life that is in it. When people around the world put trash in the ocean the life in it can die because of plastic then the fish that's eat the smaller fish won't have anything to eat and they could starve to death and then it would do it again and again until there are no more fish in the sea because people put plastic in the ocean. So that is why we need to pick up our trash and throw it away or recycle it.

    the trash gets in the water because of boats the stuff may fall of.or may be when they go fishing it might get stuck (the fishing net).they have an island that has all the trash on it.the trash is on an island that is twice the size of Texas.when he went diving he thought how can i fix this and now he is.

    I feel like when there is trash in the ocean that it hurts the animals because it is really bad and I think that people don't understand hat they are doing when they litter.
