Discarded plastic will outweigh fish in the world’s oceans by 2050, according to a report from the Ellen MacArthur Foundation. That is, unless overfishing moves the date up sooner.
The study, a collaboration with the World Economic Forum, found that 32 percent of plastic packaging escapes waste collection systems, gets into waterways, and is eventually deposited in the oceans. That percentage is expected to increase in coming years, given that the fastest growth in plastic production is expected to occur in “high leakage” markets—developing countries where sanitation systems are often unreliable. The data used in the report comes from a review of more than 200 studies and interviews with 180 experts.
Since 1964, global plastic production has increased 20-fold—311 million tons were produced in 2014—and production is expected to triple again by 2050. A whopping 86 percent of plastic packaging is used just once, according to the report’s authors, representing $80 billion to $120 billion in lost value annually. That means not only more plastic waste, but more production-related oil consumption and carbon emissions if the industry doesn’t alter its ways.
