Famine has been known since records of human population exist.
As has poverty.
To an extent both are a relative measure, in that very few people die of famine but millions do not attain a diet that allows a fullsome life. And whilst people can be classified as 'poor' it is always relative to someone else.
An absolute measure is no food or water, ergo death in 8 to 21 days or, in the case of poverty having control over nothing, ergo having no choices.
All the writers on this forum have food, water and are able to make choices and, mercifully, we are all grateful for that. I also know that many give something out of their surplus (or necessities) to the benefit of those less fortunate.
Because both these terms are largely relative in meaning famine/starvation and poverty will exist until the sun goes out.
We are not saying nothing can, or should be, done to alleviate starvation or poverty, but that what is needed is a level of support up to the point where people have choices to make.
For example I wholly support those farmers who donate cows and teach husbandry etc and do not support those charities that dump vast quantities of commodities on local populations thus destroying markets for local growers.
Despite knowing that none of us will live for ever. Security of anything including food, is dependent on the number of options we have and the choices we make, and, to push the point a little, that is why the notion of 'free trade which increases options, is better than protectionism which limits them.
