This is like going to the animal shelter and wanting to take home all the puppies to save them, but ya know you can't. Sorry if that's too blunt for some folks.
The trick is to learn to harness Mother Nature, to learn to use your environment. You can accept famine, which is cyclical as you point out, or you can learn to build with the building blocks your environment affords, or you can migrate. Death is not inevitable if you don't accept it as such.
Its not only a matter of developing technology, its also a matter of developing cultural habits of collaboration that tend toward the modification of the environment rather than living at its mercy. It can be taught, it can be learned. Charity is not enough, it has to be combined with development or we will be right back here in another decade doing it all again.
