For almost a century Big Tobacco fooled smokers into believing that cigarette filters were made out of cork or cotton. We now know that cigarette filters are made out of plastic. As the world’s most littered item, it is crazy that the act of littering them remains socially acceptable. Once tossed onto our streets – these pervasive little things get washed down drains as run-off when it rains. Traveling through water-systems, into rivers, and eventually into our oceans… it’s a problem at horrific scale. Over time, the sun’s UV rays break up a cigarette butt into tiny pieces of plastic (micro-plastic). As a result: cigarette butts are estimated to be the biggest contributor to micro-plastic pollution in our oceans. Yes – even worse than straws and plastic bags! A healthy marine eco-system is perhaps our best weapon against climate change. This should make plastic cigarettes – and the companies who make them – enemy number one.
