I am most happy to be associated with CHASE Africa because they address one of the most important topics for the future of both humans and the conservation of all biological species. Our planet has a certain carrying capacity which we are already far exceeding in the developed world and to improve the situation for the less developed world we need to stabilise population. CHASE is tackling a problem that few conservation organisations dare to touch. All the work I and others do to conserve the plants species of the world will be of no avail if we do not do something about population growth.
