If only the answers were as simple as the question.
Refugee populations trying to escape from corrupt governments, tribal conflicts, religious persecutions ... they can't farm and raise crops while living in refugee camps where they have to depend on trucked in water and food. Just one source of a decline in global food production.
And, then there are natural disasters - like droughts, floods and typhoons. They wipe out crops - and delay replanting.
Money from developed countries does little to help if there is no excess food to buy.
And, there are cultural differences ... what one culture eats - and what may be a surplus in another. I remember hearing that a religious group in a country was telling people that the peanut butter being dropped by the US to help relieve the food shortage was made from "pork" - which was a no-no in their culture - the devout would rater die of starvation, and see their children die of starvation, than defile their bodies.
We can refuse to eat endangered species ... and refuse to eat at restaurants that include them on the menu - like Chilean Sea Bass ... but it does little good if you don't tell the owner why you are not going to eat there before you get up and walk out.
Globally - rice production is down due to natural disasters. The late spring and heavy rains in our "corn belt" region is going to cause a shortage in corn production in the US this year - depending on the rains in July and August - if could be even worse.
Several countries have programs that send people into 3rd world countries to help them increase their agricultural production. But, it doesn't do much good if they are being chased off the land.
And, there is the Catch-22 of the Amazonian tropical rain forests being cut down to clear land for farming - to grow food.
So, seans - you started this thread. What are you doing and what is your answer????
I think we should increase our consumption of beef so that the demand exceeds supply ... that way there are less cows in the field producing methane gas via bovine flatulence .... this will decrease the imapct on the ozone layer ...
FWIW - global warming began the day following the end of the last ice age - just like in the previous cycles.
