I disagree with just about everything you said. The ecosystem is worthless without an intelligence to experience it. For self-aware species, death is a disease despite the fact that it maintains a consistent ecosystem. As a self-aware being, we all should have the right to live and die on our own terms.

I doubt you would speak as you did if were, in fact, next to a loved one on their death bed.

But then again, this is all a matter of opinion. We're all entitled to our right answers :)
