But the so-called balance of nature is constantly changing, with or without human influence. At present humans are changing it faster than in the past, mainly because our population is growing so rapidly. The pigeons were shifting seeds around long before humans reached NZ but their population numbers had probably stabilised to some extent within two or three hundred years of their arrival. The moose could just as likely been frightened by a wolf.

Canuck. Have you any suggestions as to how we could "Help the undeveloped become developed"?
