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

Biodegradable wastes are decomposed by the microorganisms into simpler substances which can be used by the producers as raw materials. But the following are the effects of too many biodegradable wastes:

• As the decomposition of biodegradable wastes is slow, they produce an awful smell, and when inhaled by humans, it can be harmful.
• The dumping areas can be a place where harmful organisms may start to breed, which can be harmful to humans as well as plants and animals.
• An increase in the number of aquatic organisms may result in the depletion of oxygen.
