Greenpeace is campaigning for safe, ecological agriculture that's good for the planet and good for people. China has one of the world's greatest agricultural dilemmas: it must feed over one-fifth of the world's population on just a fraction of the world's land.

Unfortunately, China has adopted an unsustainable solution: a chemical-intensive system of agriculture, with high levels of chemical pesticide and fertiliser use. What's more, our food supply is also threatened by genetically engineered foods – a move that would gamble with the health of millions of people.
