Then we did a research on the different types of pollutants, shared our findings in class, and agreed that nowadays plastic is one of the greatest water pollutant. It is basically made of natural materials such as cellulose, coal, natural gas, salt, and oil through a polymerization or polycondensation process. 

Plastic is non-biodegradable, and it is estimated to take between 100 and 1,000 years to decompose, which is why it is considered a very slow and long-term decomposition material. A plastic bottle takes up to 500 years to disintegrate, although if buried this time is even longer. 

There are several solutions to avoid plastic: REDUCING, REUSING and RECYCLING.
