1. These are not even comparable dangers. Reduction in infant mortalty by 98% versus what.. some hormone issues sometimes in some people??
2. The laws of physics have so far prevented us from making technology like a tiny portable button that blows up a planet. Id assume a universe with weak energy constraints like that would have yielded much larger scale organisms, or perhaps none at all.
1 is you get a scratch then die because your body rots and you can do nothing about it. May want to spend some time learning about antibiotics resistance.
