Polythene which became very popular within about 25 years has now become the world's biggest problem. We all know that it is harmful not only to human life but to animal life and the environment as well.
Polythene became very popular because it made our daily tasks very easy. It was used for carrying things, wrapping, decorating, as coverings and even in making artificial ornamental items. It came in various colors, shapes and sizes as bags, squares, sheets and rolls of polythene.
However, the common polythene bags and lunch sheets became the biggest problem in Sri Lanka. As students we are also guilty of using them for anything and everything. We did not know how to dispose them properly and carelessly threw away in drains, waterways, on roadways, in parks, in forests, on beaches and so on. So now we have to face the effects. The danger is that polythene is not bio - degradable. That means it does not rot easily. If it is buried it can harm the soil. Burning it causes air pollution. The worst effect is that animals, birds and fish have died after eating thrown away polythene.
Now most people and even children are aware of the dangerous and use other materials like clothes and paper which are bio - degradable. So, all of us must to be responsible in everything we do because this is our beloved country.
