Answer 1

2. To keep the body's internal environment in balance.
If the body didn't eliminate waste, that would be bad. Imagine if you never took out the trash in your house and trash bags were lying everywhere. Not only would it overflow your house at some point in life, but it would be messy and your house would never be clean. It's the same with eliminating bodily waste.
