Why do "We" in the West have to do anything for these poor impoverished starving countries?
Give me a compelling rational reason - not your emotional rubbish about morals or Christian attitude. I don't care about any of the places you mention - let them breed or starve themselves into extinction - there are far too many on the planet now and some parts ( the parts you fret over) are causing most of the problems - pollution etc.
You need to curb your condescending nonsense - it fools no one. Simply an empty vessel making lots of noise.
By the way I am very specific in who I blame for much of the planet's problems - just look where all the population growth has occurred and that's where all your pollution is.
Ever been to a beach in Indonesia - al the crap along the beaches is locally produced and consumed products - and they have the hide to charge tourists for the clean up.
