Spotlight: 'Plastic is more dangerous in the oceans than on land’

Malcolm Doyle is as mad as hell about plastic pollution on our beaches and oceans and, what's more, he's prepared to do something about it. Last year, the 28-year-old spent his annual leave cleaning up 60 beaches from Adelaide to Port Douglas. He estimates two-thirds of the litter was plastic, especially flimsy takeaway bags, beverage bottles and coloured bottle tops that some sea birds mistake as food. "I never felt so positive from the community support and disheartened by the level of waste at the same time," he recalls.

Recent headlines warning that our oceans will have more plastic than fish by 2050 may seem incredible, but in reality it may be worse, observes Doyle. The throwaway society has gone global, with plastic production predicted to double in the next 20 years, according to Science magazine. The Plastic Vortex, the swirling mass of garbage bobbing in the north Pacific Ocean, is already twice the size of Texas, according to Greenpeace. Now scientists, who have got better at detecting chemicals in our bodies, are finding that even tiny quantities of plastic toxins can have potentially serious impacts on human health.
