According to a study jointly conducted by IO-USP and Plastivida, more than 95% of beach waste in Brazil is made of plastic products such as bottles, straws, fishing nets and the like.
Brazil's "BBCBrasil" reported on January 23 that IO-USP and Plastivida monitored the three beaches in São Paulo State, the three beaches in Bahia and the three beaches in Alagoas. The staff cleaned the beach first Out of a piece of sand, and then go back some time for garbage collection.
The investigation revealed that the pollution in the beaches of São Paulo State was caused mainly by fishing activities, while the pollution in Bahia and Alagoas in the northeast was due to tourism.
Alexander Turra, an IO-USP biologist, said the goal of the project was to educate the environment on the proper understanding of the waste and to keep the oceans and beaches clean. "This research has led us to discover that the issue of marine litter is not a problem in coastal cities and involves all states and cities, including basic sanitation, environmental education and social culture," he said.
Miguel Bahianse, president of Plastivida, said the issue could only be solved by the various departments. "We are conducting publicity and education, which requires the participation of the whole society, including the power sector, all industries and the general public, because we all share a common goal of protecting the sea and the environment," he said.
There is not much research on marine litter either in Brazil or abroad. More than 80% of marine litter comes from land, such as trash generated by economic activities, municipal waste, poor management of port and tourism trash, as well as the indiscriminate disposal of rubbish on streets and rivers, causing so-called diffuse pollution. There are still 20% of the garbage from the ocean, such as people's fishing, diving, cruise ships and so on.
Brazil ranked 16th in a list of marine pollution released in 2015. It was pointed out in the report that the annual amount of plastic trash discarded by the beaches in the world's coastal countries is between 70,000 and 190,000 tons.
