"Yet food is something that is taken for granted by most world leaders despite the fact that more than half of the population of the world is hungry." - Norman Borlaug
"Our population and use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill." - Stephen Hawking
