There is a whole range of metrics as we are looking at the span of human life. The most easiest to measure is life span.
Like any scientific measurement you have a +/- range attached and in some countries that data is going to be more fuzzy... And probably a correlation to how dangerous that country is as not even birth records are viable.
Greenpeace can whine until they choke on their on anti scientific hubris. 3% of the worlds energy budget goes into fixing nitrogen into the worlds soils. The science of agriculture and chemistry have allowed a true green revolution that has tripled our ability to feed people. Greenpeace is blocking as much of this as possible in the GMO sphere.
Anyhow lots of data for human life can be used. Main thing is to look at the trends and vectors. Human lifespan has doubled for most people in the last hundred years.
