Solution

As we know that 3 R are very important to keep our environment with less pollutants. These 3 R are reduce, reuse and recycle.
If the waste segregation is not done it would hamper the process of recycle and reuse of recourses and in this way it would increase the extra burden of pollutant on environment.
