Dumping of waste material made up of metals and non-metals leads to environment pollution. Do you support the statement? Give your justification with suitable examples.

I totally agree with the statement. Following points support my argument :

a) Metals such as Iron, copper are not bio-degradable and takes thousands of year to get decomposed that leads to soil pollution,

b) Metals such as Lead and Mercury should not be thrown away directly as they are poisonous and leads to air and water pollution.

c) Oxides of Carbon and sulphur (non-metals)contribute to acid rain and thus lead to water pollution.

d) Excess of Nitrates (non-metal) in the soil helps in the growth of disease-causing germs which ultimately leads to water pollution.

e) An excess amount of calcium ( non-metals) decreases the alkalinity of water which increases the growth of certain microbes and thus leads to water pollution.
