"The problem we have chosen to tackle is plastics and micro-plastics in the oceans. We chose this problem because we believe that if we don't act soon then it will be too late. It takes 450 years for a plastic bottle to degrade and our seas are full of them. Marine life is being massively affected. Not only this but it affects the human food chain because we are consuming fish with microplastic in it which can cause serious diseases. Another impact of the plastic in the ocean is that marine life is becoming entangled with it. This causes injury and death. We don't want our marine life to become extinct for future generations."

"Our big idea is the sea saver, a device that uses hydro power to collect plastic from the sea. This product uses natures energy to take plastic out of the sea. At the front of the sea saver there is a nozzle which has been designed to stop blockages. On UK beach lines we have tides that flow in and out. To make our product as sustainable as possible we decided to use the seas natural tides rather than power the sea saver. There is a net, made out of the nylon to avoid erosion in the salt water, that catches the plastic and releases the sea water. The net is clipped on using clips which local fisherman can then remove to empty the plastic and clip back on. To ensure that no fish get caught in the sea saver, we have attached a radar to the bottom of the machine which the fish swim away from."

"Our big idea is beneficial because if we don't take the plastic out of the sea it will take more than 450 years to biodegrade. By this time the damage to marine life through entanglement and consuming plastic will be catastrophic. Our idea will also help to protect people who are eating the fish that has been infiltrated with the plastic. By taking the plastic out of the sea we are also protecting the reefs so that fish can continue to thrive. Our big idea is also beneficial to fisherman. The ocean is the world’s seventh largest economy and if we don’t try to reverse the damage that is done to it now, there will be millions of people around the world, some of them in the poorest countries, that have their livelihood stripped for them and will be unable to eat and survive."
