By 2050, the amount of plastic "will far exceed" the weight of all fish in every ocean, the EIA said. Humankind's "addiction to plastic" and failure to prevent the material from contaminating the food chain directly undermines human health, drives biodiversity loss, exacerbates climate change, and risks "generating large-scale harmful environmental changes", the agency said. EIA ocean campaigner Tom Gammage said that if the "tidal wave of pollution continues unchecked", plastic discharges into the oceans alone will triple by 2040, in line with growing plastics production.
