Marino Morikawa, a Peruvian scientist, has set his eyes on removing the pollution in Lake Titicaca after reviving some polluted wetlands in fifteen days. Morikawa uses nanotechnology to answer the problem of pollutions, something that’s becoming more and more popular. El Cascajo, the ecosystem in which the revived wetlands were positioned in, began its renewal using Morikawa’s own funds. The wetlands he had restored were filled with waste from illegal dumping. It was home to many aquatic plants and migratory birds, all of which had to cope with the tainted environment. Morikawa set out to cure the problem, first, using a micro-nanobubble system that trapped viruses and bacteria (and eventually destroyed them). In addition, he used biological filters which caught effluents such as heavy metals. The filters, which consisted of bacteria that could decompose the contaminants, would then continue to get rid of the pollution. Since then, the wetlands has seen its biodiversity increase. By 2013, the migratory bird population in the area had returned to the pre-pollution levels. Morikawa believes that all he is doing is giving nature a “boost” on what it normally should do.
As such, he has helped recover over thirty habitats around the world, and now sets his wheels toward Lake Titicaca, the largest river in South America. Like the wetlands, the lake is heavily polluted by sewage. As officials state, the sewage seems to come from industries nearby that fail to follow safety guidelines or manage to find loopholes in them. Along with sewage, the lake’s shores sport discarded plastic bottles, soda cans, old tyres, rubbish, clothes and animal waste. Because of the above reasons, Lake Titicaca is suffering quite badly, along with the creatures it supports. Read more about Morikawa’s expenditures here.
