If all the waste we generate is biodegradable, will this have no impact on the environment ? [CBSE 2011, 2013]

If all the waste we generate is biodegradable, it will also have impact on the environment. If it is disposed off properly, the problem of air, water and soil pollution can be lessened to an extent. There would be less health problems and humans would be disease-free. But if it is not disposed off properly, it will affect the environment adversely.
