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

If all the waste we generate is biodegradable, it will have an environment friendly impact as pollution by non-biodegradable substances will reduce but it will definitely have an impact on the environment. This is because a lot of biodegradable waste cannot be decomposed all together by micro-organisms at once which will lead to piling up of the wastes and thus giving out foul odor. The place will also become a breeding ground for mosquitoes thus leading to spread of diseases.
