Colonisation is OVER

European countries have colonised and used Africa's land and people for some time, from the Portuguese to the British, and yet we've stopped trying to "take over" African countries.  Contemporary times seem to be focused on reparations or dealing with the consequences of colonisation, instead of continued use and exploitation of the land.  Why?  Is the land that shitty that agriculture won't continue to thrive?  Are the people that lazy that they can't force everyone to work towards industrialising civilization? 

Also, how can we terraform dry and arid land into fertile soil in order to grow crops?  This applies to Africa, the middle east, and parts of asia.  There is so much unused land, so why can't it be infused with nutrients, fertilizer, nitrates, etc.

Alot of the problem in the third world are a direct or in-direct result of the west's "smash and grab" mentality.

It's been several decades since the West left most of Africa to its own devices. Unlike Asia, Africa has very little to show for it. The problem lies within.
