Ecologists want plastics declared hazardous

Despite efforts to reduce and recycle plastic, the planet is still awash with wayward wrappers, bottles and bags.
Almost half of the world's marine animals and a fifth of its seabirds are at risk of becoming entangled or eating the stuff, which has now prompted an international group of ecologists to call for the worst plastics to be declared hazardous materials.
Without action, they estimate, the planet could have another 33 billion tonnes of plastic by 2050.
