If all the waste we generate is biodegradable, will this have no impact on the environment.

Explanation

Even the biodegradable wastes cause the environmental pollution. Accumulation of biodegradable wastes are responsible for:
(i) The excess of domestic sewage and nitrates from fertilizers cause excessive growth of phytoplanktons called algal bloom, which in turn kills the aquatic animals.
(ii) The heaps of biodegradable solid wastes destroy the natural beauty of the landscape and make the surroundings unhygienic.
(iii) The decay and decomposition of such wastes produces foul gases and causes air pollution.
