Look. We need to stop damaging our only life support system. A system on which, factually, we all depend (whether you recognize it or not).We need to share our world with all the other species that live on it. Respectfully. Harmoniously.And we must stop being the cause of their disappearance. Their extinction.We must also learn to live with what natural resources are available to us. It's not hard. It's not rocket science. It just means that in living, we must stop polluting. And poisoning. And being so outrageously wasteful. Let's take a look at one of the main reasons why animals living in the coral reefs are endangered-pollution. Over 80% of marine pollution comes from land-based activities A staggering amount of waste, much of which has only existed for the past 50 years or so, enters the oceans each year. From plastic bags to pesticides - most of the waste we produce on land eventually reaches the oceans, either through deliberate dumping or from run-off through drains and rivers. This includes: -oil -fertilizers -solid garbage -sewage -toxic chemicals OIL SPILLS cause huge damage to the marine environment - in fact, oil spills are responsible for only around 12% of the oil entering the seas each year. According to a study by the US National Research Council, 36% comes down drains and rivers as waste and runoff from cities and industry.Fertilizer woesFertilizer runoff from farms and lawns is a huge problem for coastal areas. The extra nutrients cause eutrophication - flourishing of algal blooms that deplete the water's dissolved oxygen and suffocate other marine life. Eutrophication has created enormous dead zones in several parts of the world, including the Gulf of Mexico and the Baltic Sea. Several years ago a minke whale was found on a Scottish beach with 800kg of plastic bags in its stomach. SEAS OF GARBAGE Solid garbage also makes their way to the ocean. Plastic bags, balloons, glass bottles, shoes, packaging material - if not disposed of correctly, almost everything we throw away can reach the sea.Plastic garbage, which decomposes very slowly, is often mistaken for food by marine animals. High concentrations of plastic material, particularly plastic bags, have been found blocking the breathing passages and stomachs of many marine species, including whales, dolphins, seals, puffins, and turtles. Plastic six-pack rings for drink bottles can also choke marine animals.This garbage can also come back to shore, where it pollutes beaches and other coastal habitats. SEWAGE DISPOSAL In many parts of the world, sewage flows untreated, or under-treated, into the ocean. For example, 80% of urban sewage discharged into the Mediterranean Sea is untreated.This sewage can also lead to eutrophication. In addition, it can cause human disease and lead to beach closures. What are you waiting for? SAVE THE CORAL REEFS! JuneSu=P
