Rio Beach Pollution BY: kaitlyn p and melissa

Rio has been having troubles with sewage leaks and beach pollution that can hurt the coastal economies.

This is happening in Rio de Janeiro (Guanabara Bay)

The environment is being effected with financial impacts because economists have estimated that a typical swimming day is worth approximately $35 for each beach visitor.

Polluted beach water affects humans because swimmers get sick with which includes stomach flu, skin rashes, pinkeye, respiratory infections, meningitis, and hepatitis. Also animals affected because they are killed by the ingestion of plastic, rubber, or foam they mistake for food. For example both sea birds and sea turtles are affected do to this.

1-The biggest source of pollution in the ocean is directly from land based sources, such as oil, dirt, septic tanks, farms, ranches, motor vehicles, among larger sources. Thousands of tons of waste and trash are dumped into the ocean on a daily basis.

2-Each day thousands of tons of trash and waste are dumped into the oceans of the world.

3-Radioactive waste and industrial waste such as acids and toxins often reach the ocean adding to the pollution and substantial loss of marine life.

4-One key issue is that it can develop in areas near pollution sources after a heavy rainfall or when a sewage treatment plant malfunctions. So these problems need to be fixed so it's not likely to happen often.

5-"Swimmers need to ingest only three teaspoons of water to be almost certain of contracting a virus" is another key issue. The AP's survey of the aquatic Olympic and Paralympic venues concluded consistent and dangerously high levels of viruses from the pollution. The first results showed viral levels at up to 1.7 million times what would be considered worrisome in the United States or Europe. At those concentrations, swimmers and athletes who ingest just three teaspoons of water are almost certain to be infected with viruses.

When they took a testing of the antibiotics people took to prevent the virus and found it was 90 percent Dr Valerie Harwood, chair of the Department of Integrative Biology at the University of South Florida said "That's a very, very, very high percentage" and "Seeing that level of human pathogenic virus is pretty much unheard of in surface waters in the US. You would never, ever see these levels because we treat our waste water. You just would not see this."

-As part of the latest ‘Clean Guanabara’ plan announced by the government, when planning for the 2016 Olympics, seven new sewage treatment plants were promised. Disappointingly though, only one plant is in operation.

-Previous promises from Rio officials to “regenerate Rio’s magnificent waterways” through investment in sanitation have not delivered results.

- Some of the country’s leading waste experts pulled together, including businesses and NGOs, to propose a variety of innovative solutions under the name Clean Urban Delta Initiative.

-In the future we can do beach clean ups before the trash gets to the ocean and also check on the sewage's to make sure they don't spill.

-Students and adults can prevent this problem by getting involved in programs and helping out by doing cleanups, making sure to not litter, etc.

Do you really want animals to die and more people to get sick? I wouldn't think so. But what you should do is act now and get involved in a beach clean up program. Because in the end pollution hurts the environment, kills animals, and puts harm to many things.
