Plastic seas

The plastic seas are a real environmental problem caused by man that should concern us.

plastic debris causes the deaths of more than a million seabirds every year,
as well as more than 100,000 marine mammals. Syringes, cigarette lighters and
toothbrushes have been found inside the stomachs of dead seabirds, which mistake
them for food.

Plastic is believed to constitute 90 per cent of all rubbish floating in the
oceans. The UN Environment Programme estimated in 2006 that every square mile of
ocean contains 46,000 pieces of floating plastic,

Dr Eriksen said the slowly rotating mass of rubbish-laden water poses a risk
to human health, too. Hundreds of millions of tiny plastic pellets, or nurdles –
the raw materials for the plastic industry – are lost or spilled every year,
working their way into the sea. These pollutants act as chemical sponges
attracting man-made chemicals such as hydrocarbons and the pesticide DDT. They
then enter the food chain. “What goes into the ocean goes into these animals and
onto your dinner plate. It’s that simple,” said Dr Eriksen.
