Plastic bags are very popular in our life. Everyday, plastic bags are used for variation purposes because plastic bags are convenient, as they are waterproof, light and inexpensive compared to other kinds of bags. Nevertheless, the using without control makes the quantity of plastic waste becoming alarming and can lead to a serious environmental hazard. This is the reason why the plastic bag is one of elements contributing to environmental damage especially the marine environment.
Ocean polluted by plastic bags is the result of human awareness. People use plastic bags all the time, however, they just do not concern about what happens to the millions of plastic bags which they throw away. Although plastic waste can go to landfill but it still stay for long period of time. Because of their light weights and difficulties in containing, plastic bags fly easily in wind, float along readily in the currents of rivers and oceans. Ocean polluted by plastic bags is often also the result of human laziness. People go to the beach with lots of plastic bags of essential items or food, afterwards, they hardly collect bags and simply allow the bag to disappear into the wind and waves (Harrison, 2014). Consequently, millions tonnes of plastic bags is dumped into the world’s oceans per year. However, plastic bags are not easily disappear in the water because most plastic bags take up to 1,000 years to degrade on land and 450 years in water (BBC news, 2002). Plastic bags can not disintegrate like natural materials under the effect of sunlight and wave. They float on the ocean’s surface, spread even further afield and are easily eaten by fish and other marine species (Greenpeace, 2014). These reasons can explain why more and more plastic bags appear in the ocean every passing year without decomposition.

Plastic bags floating on the ocean are killing so many marine species every
