There are four major kinds of pollution:
i) Air pollution
ii) Water pollution
iii) Land (soil) pollution
iv) Noise pollution

Old cloths and some plastics are the recycleable things.

(i) Learning food chain help us to understand the feeding relationship and interaction between organisms in any ecosystem.
(ii) Understanding the food chain also helps us to appreciate the energy flow and nutrient circulation in an ecosystem.
(iii) The food chain can be used to understand the movement of toxic substances and their impacts.

i) Do not pour leftover oil, old medicines or waste down the drain or into the toilet.
ii) Reduce the use of chemical pesticides and fertilizers to grow crops.
iii) Use waste water for garden in home.
iv) Do not litter or dump waste - always use a waste bin.

AVOID:
Avoid the usage of unwanted materials which create more debris.
(e.g) (i) Avoid buying packaged foods.
(ii) Refuse to buy use and throw plastic products.
REDUCE:
We can reduce the waste by using durable goods that last longer instead of things that are used once and thrown away.
(e.g) (i) Write both sides of papers.
(ii) Instead of unnecessary printing use electronic facilities.

(i) If we remove an organism from the food chain leads to lack of energy transfer to higher trophic level organism and it will become to die.
(ii) So the entire ecosystem will affect.
