The charm of the ocean lies in its sparkling. Under the light, the ocean seems to be a cheerful child, full of vitality. However, with the continuous accumulation of garbage, the ocean gradually becomes dark, and those lights are also swallowed up by a large number of floating marine garbage. A large amount of garbage destroys the homes on which marine life depends, and the light of their lives is eroded by garbage. Therefore, we hope to return those lost lights to the sea and those marine life, so that the sea can be revitalized!Maldives, an archipelago country famous for its beautiful natural environment in the Indian Ocean, will attract tens of millions of people to come for vacation every year. Because of this, the garbage on the island is difficult to be reasonably treated. A large amount of garbage is put into the sea, and is gradually forming a marine garbage Island larger than Japan.At the same time, the garbage problem is also affecting the quality of life of local residents in Maldives, especially the plastic garbage that is difficult to decompose, causing many beaches to be difficult to go to sea.At the same time that the environmental problems in Maldives are becoming more and more serious, the garbage floating with the waves is becoming a worldwide problem. Due to the special characteristics of the Indian Ocean, the garbage entering the ocean from surrounding countries will circulate with the ocean current and eventually converge in Maldives, making the situation worse there. Moreover, the area of the marine garbage island is growing at a rapid rate. If it cannot be treated in a timely and effective manner, In the near future, the Indian Ocean coast will be covered with plastic garbage and cannot be carried away by ocean currents.We use simple green environmental protection materials to make the main body of the device, use the potential energy brought by the wave fluctuations to provide energy for the whole device, and gather the ubiquitous sunlight in nature to provide high-energy ultraviolet and temperature for the reaction device. In the chemical reaction with titanium dioxide as a catalyst, the plastic garbage floating on the sea surface can be decomposed into harmless carbon dioxide and water faster and more efficiently, Address the growing garbage islands in the Indian Ocean and Maldives.Finally, the connecting line between the sea level and the sky is no longer white garbage, but a blue, shining ocean.
