It's no secret how Africa can feed itself - grow more food.
That sort of naïve statement is fine for environmentalists who were born as part of the Agricultural 1%, but it falls apart in the real world that exists outside fundraising campaigns. A large chunk of Africa doesn't grow food all that well, which historically has meant relying on the patronage of rich countries and cycles of famine - but that also has made it a political football.
As most culturally astute people of a certain age know, 2015 is "The Future" of "Back To The Future II." "Back To The Future" was, of course, a seminal comedy in 1985 - a time when terrorists were from the Mid-East and you could do a time-travel experiment on your dog without getting protests outside the theater.
Artificial hearts were invented at a time when progress in science couldn't come fast enough.

In George R.R. Martin's "A Song of Ice and Fire", a wall separates two very different people - think England and Scotland. South of The Wall, the people of Winterfell are always preparing for the worst. North of The Wall, they are just living their lives and rolling with the punches. And there is a lot more (consensual) sex. These two groups live in the same world but approach it in very different ways.
