Ecological footprint and expetancy of life

The only species that can do anything to save others is mankind. But only if mankind goes on on the way to progress. No cat, no snake, no hen can save bears, only mankind can. We need to love mankind, and progress.
Some people told us men are guilty, and progress is guilty, and we should stop progress, and reduce mankind. But progress means a longer life. In ancient times life expetancy was very poor, and progress increased it very much. Was it a fault, or a merit ?
Compare life expetancy in different countries:
http://en.wikipedia.org/wiki/List_of_countries_by_life_expectancy
with that unscientific index called "ecological footprint"
http://en.wikipedia.org/wiki/Ecological_footprint
and you will understand what progress mean... more life, and what ecological footprint means...less life !
In my opinion
