This month's National Geographic has an interesting article about food waste, I read it on the flight home from LA a few weeks ago. It opened my eyes to how I purchase food for home, I pay more attention to quantity, especially with fruit and veg and anything that will spoil quickly.

According to National Geographic, by 2045 the population will likely have grown from 7 billion to 9 billion people.

Julian Cribb, author of The Coming Famine, says higher yielding crop varieties and more efficient farming methods will be crucial. So will waste reduction.
