Eighty per cent of ocean pollution is caused by human activity on land. Billions of litres of untreated sewage flow into our waterways, and contaminants are then passed along the food chain. For many marine species, the sea is turning into a deadly obstacle course, as plastics and other waste become unwelcome travelling companions.<\/p>\n
Approximately 260 million tonnes of plastic is produced every year, 10 per cent of which finds its way to our oceans. Nearly 80 per cent of marine litter is ushered into the sea via wind and runoff \u2014 litter from our roadways make its way to our streams and rivers and eventually gets dumped into our oceans. The remaining debris that enters our waterways comes from ships.<\/p>\n
So what happens to the plastic once it gets in the water? The carbon dioxide in the water and the sun\u2019s heat and rays cause the plastic to break down into tinier and tinier pieces. But don\u2019t be mistaken. The plastic doesn\u2019t go away. It just gets smaller. These pieces can weigh as little as a tenth of a paper clip. That\u2019s mini!<\/p>\n

But don\u2019t be mistaken. The plastic doesn\u2019t go away. It just gets smaller. These pieces can weigh as little as a tenth of a paper clip. That\u2019s mini! From rubber duckies to tampon applicators, everything we toss in the trash has a gravesite. If it doesn\u2019t end up in a landfill, it inevitably finds its way to the ocean. And as the plastic breaks down into smaller and smaller bits, it often ends up in the bellies of wildlife. Fish, for instance, are unable to distinguish these pieces of plastic from plankton, and readily chow down on it. According to the U.S. National Oceanic and Atmospheric Association, up to 100,000 marine mammals have trash-related deaths each year. Moreover, upwards of 50 per cent of marine reptile species are affected by plastic litter, and a million seabirds become entangled in plastic nets or choke on plastic debris every year.\u00a0Plastic bags, fishing gear, six-pack rings and glass bottles and other marine debris can remain in the environment for years, killing or injuring right whales, leatherback turtles and many other migratory species that become entangled in the garbage or mistake it for food.<\/p>\n <\/p>\n
\nA \u201cgarbage patch\u201d is created when marine litter<\/a> is whirled together by a vortex of currents. There are currently five gyres in our oceans: the North and South Pacific, the North and South Atlantic and the Indian Ocean. These gyres make up 40 per cent of the sea.\u00a0 That\u2019s 25 per cent of our planet where plastic garbage is accumulating!<\/p>\n
