How can Africa, with ballooning population, achieve food sufficiently while at the same time keeping an eye on the environment.
I'm half African so permit me to give you my humble opinion.
The first thing would be to prevent foreign nations and corporations out of Africa from exploiting the rich natural resources of the continent and exploiting the African population.
Second, the African nations need a common central bank and its own currency complete with a trade strategy to rival the rest of the world.
Third, the continent of Africa needs its own military and peace-keeping force independent of all other nations, complete with a counter-terrorism task force and a central intelligence worth its name.
Fourth, Africans need to vote on a council representing an African Block that would oversee those above measures.
Fifth, that council needs to have a clear and enforceable term limit to ensure full democracy and freedom for all.
Sixth, that African council needs to draft a constitution common to all the African nations, approved by all native Africans and free from foreign interference.
Seventh, the African block needs to develop a strong manufacturing base to rival with foreign imports and create jobs.
Eighth, the African block needs a clear and practical outlook of its destiny and develop a continent-wide technological program to propulse it into the future, complete with an independent space and viable health programs.
Ninth, quit selling each other out to foreign nations.
Tenth, quit thinking in tribal terms.
