Plastics are used because these are easy and cheap to make and they can last a long time. Unfortunately these very useful qualities make plastic a huge pollution problem. Because the plastic is cheap it gets discarded easily and its persistence in the environment can do great harm. Unbanization has added to the plastic pollution in concentrated form in cities.
Plastic thrown on land can enter the drainage lines and choke them resulting into floods in local areas in cities as was experienced in Mumbai, India in 1998. It was claimed in one of the programmes on TV channel that eating plastic bags results in death of 100 cattle per day in U.P. in India.
In stomach of one dead cow, as much as 35 kg of plastic was found. Because plastic does not decompose, and requires high energy ultra-violet light to break down, the amount of plastic waste in our oceans is streadily increasing.
More than 90% of the articles found on the sea beaches contained plastic. The plastic rubbish found on beaches near urban areas tends to originate from use on land, such as packaging material used to wrap around other goods.
On remote rural beaches the rubbish tends to have come from ships, such as fishing equipment used in the fishing industry. This plastic can affect marine wildlife in two important ways: by entangling creatures, and by being eaten.
Turtles are particularly badly affected by plastic pollution, and all seven of the world’s turtle species are already either endangered or threatened for a number of reasons. Turtles get entagled in fishing nets, and many sea turtles have been found dead with plastic bags in their stomachs. Turtles mistake floating transparent plastic bags for jellyfish and eat them.
In one dead turtle found off Hawaii in the Pacific more than 1000 pieces of plastic were found in its stomach. A recent US report concluded that more than 100000 marine mammals die every year in the world’s oceans by eating or getting entangled in plastic rubbish, and the position is worsening world-wide, 75 marine bird species are known to eat plastic articles. This includes 36 species found off South Africa.
A recent study of blue petrel chicks on South Africa’s remote Marine Island showed that 90% of chicks examined had plastic in their stomachs apparently fed to them accidentally by their parents. South African seabirds are among the worst affected in the world. Plastics may remain in the stomach, blocking digestion and possibly causing starvation.
Since the development of plastic earlier this century, it has become a popular material used in a wide variety of ways. Today plastic is used to make, or wrap around, many of the items we buy or use. The problem arises when we no longer want these items and we have to dispose off them, particularly the throwaway plastic material used in wrapping or packaging.
Plastics are used because they are easy and cheap to make and they can last a long time. Unfortunately these same useful qualities can make plastic a huge pollution problem. The cheapness means plastic gets discarded easily and its long life means it survives in the environment for long periods where it can do great harm.
Because plastic does not decompose, and requires high energy ultraviolet light to break down, the amount of plastic waste in our oceans is steadily increasing.
