Jesus told us that the poor will always be with us. That fact has nothing to do with "sustainable development". Instead, we all need an individual change in our hearts to effect a permanent and real improvement to the inequalities in our world. That can be accomplished only by Jesus as we each ask Him to enter us and do what we are incapabale of achieving by our own efforts. 

I'm sorry, Francis, new scientific rules and regulations are only window dressing for a sinful world.
