Sir Paul Callaghan said getting rid of the pests was essential, but it would be our Apollo moon shot, and he was right. The late Sir Rob Fenwick, who I first met on a television garden show 30 years ago, and who had a profound influence on my thinking, was a visionary who made an enormous contribution and helped convert our distant moon shot prospect into something down to earth and well within reach. We are, of course, only the custodians of this land. We are the kaitiaki, the guardians, of our grandchildren's natural heritage. We owe it to them to do better and to try harder to save our kiwis and our other endangered native species. I encourage people to put aside their prejudices about genetic modification and also prejudices about 1080. There is no time to waste.
