Except all almost all of the plastic in the ocean comes from 3rd world countries. It does not come from Canada. So anything we do here will make no difference to that problem.
Actually, countries from the far corners, including India, as well as corporations who do business in the far corners, are taking steps to deal with the problem. So your approach of hiding under your bed and pointing fingers fails yet again.
Canada, which has 151,019 miles of coastline–the world’s longest–and a quarter of the world’s fresh water, joins a growing list of nations taking steps to reduce the use of disposable plastics.
More than 60 nations have taken steps to reduce single-use plastics by imposing bans or taxes, according to a United Nations report published last year. In March the European Union’s parliament voted to ban the top 10 single-use plastic items found on European beaches by 2021. The EU measure also calls for 90 percent of plastic bottles to be recycled by 2025. Member states must work out the details of bans before the 2021 deadline.
India’s prime minister, Narendra Modi, who was overwhelmingly reelected last month to a second five-year term, declared in 2018 that India would eliminate all single-use plastic by 2022, an ambitious plan for the world’s second most populated country.
