Canada Wants to Ban Single-Use Plastics"
by Vicky Stein
From Vancouver to Halifax, plastic plates, plastic bags and plastic straws may be on their way out. But a possible country-wide prohibition on certain single-use plastic products may not address the spread of the most insidious plastic litter, some scientists say.
According to Canadian officials, the potential bans — which could go into effect as early as 2021 — would not only curb litter but also cut nearly 2 million tons of carbon pollution. They claim the policy would also stimulate the economy by creating 42,000 jobs.
“I am, like a lot of scientists, excited, with a lot of caveats,” said Max Liboiron, an environmental scientist at Memorial University in Newfoundland.
Plastics can persist for hundreds, if not thousands of years in the environment. Plastic litter can entangle and kill wildlife, or break down into tiny particles — microplastics — that collect and leach out heavy metals or harmful chemicals. While recycling can repurpose plastic materials into other products, fewer than 10 percent of plastics are actually recycled. The bulk of recyclable plastic is currently in limbo, as countries in Asia have shut their doors to shipments of other nations’ trash.
