Question

Pond water pollution protection technique in medicine

Answer 1

The water in a pond must remain clean if it is to provide a healthy environment for the organisms (animals and plants) living in it. The natural waste from the living and dead organisms is ‘recycled’ by special tiny organisms called bacteria. Plenty of oxygen is needed for the bacteria to ‘break down’ the waste. The pond can take care of its own waste – it’s people who cause pollution!
