Drowning in Plastic (BBC1, 8.30pm)

AT least eight million tons of plastic waste enter the Earth's oceans and seas each year.

One million sea birds and 100,000 marine mammals are killed annually from plastic in our oceans, while it is estimated that more than 50 per cent of sea turtles have consumed plastic. In conclusion, plastic is devastating our oceans, but can the tide be turned back before it's too late? In this one-off documentary, Liz Bonnin travels to a remote island off the coast of Australia where newly hatched shearwater chicks are filling up on deadly plastic. She also visits the Coral Triangle that stretches from Papua New Guinea to the Solomon Islands to find out more from scientists trying to work out why plastic is so lethal to the reefs. Finally, she looks at possible solutions, such as a monumental 600-metre construction that will travel across the ocean's 'garbage patches' collecting millions of pieces of plastic pollution.
