Read the passage given below :
Millions of tons of small waste from plastic bags, bottles and clothes in the world’* oceans present a serious threat to human health and marine environment. This is the stark warning issued by the U.N. in a report on the most dangerous environmental problems facing the world today. Global plastic production has increased considerably in recent years nearly by 3 8%.
A poor waste management means when we have finished with our takeaway containers, **** butts and party balloons, they are worn down into trillions of even smaller particles by the waves. Therefore, there is a growing presence of these micro plastics in the world’ oceans.
It was estimated in 2010 that millions of tons of plastic was washed into the seas and has since shown up in the stomachs of whales, plankton and other marine life. Richard Thompson, professor of marine biology said that in laboratory experiments there is proof that micro plastic can cause harm to organisms.
More than a quarter of all fish now contain plastic, according to a recent study which analysed the guts of fish sold in California.
Scientists **** that chemicals in plastics and also chemicals which attach themselves to plastic in natural environment could cause poisoning and many disorders in marine life if consumed in huge quantities.
Even humans could be adversely affected by the plastic. People could even be breathing in plastic micro particles suspended in the air with the risk of harmful effect on the lungs similar to car fumes.
Boyance Slat, a Dutch student has developed a technology that could sift dangerous plastic particles out of the ocean and sell them for profit or re-cycling. Richard Thompson recommended that people avoid using products with micro beads and to make sure they dispose of all plastic products in an appropriate way by re-cycling if possible.
