Complicated subject, subject to many varying assumptions. Just went through with Smithee in PM.
users.rcn.com

That shows that is present growth rate were to continue, we would hit a population of 46B in 2150. Supporttable? Very doubtful.

At the bottom. it shows population plotted against time assuming diffrent total fertility rates (TFRs). Stability is achieved (surprise!) at about 2. Below that, popuulation declines. Right now it is 2.8.

If population control is NOT achieved, disaster is unavoidable. Malthus WILL win.

Another interesting graph which basically shows the effect of prosperity on population:

IF you can come up with the resources to get the world pop to first world standards, it would likely stabilize and decline. If.

Chicago Botanic Garden, Royal Botanic Gardens
Partner in Global Seed Bank Program
Millennium Seed Bank Project, Kew, London

Armed with technologically efficient laboratories and botanists having nearly 75 years of combined training in plant conservation science, the Chicago Botanic Garden has signed on as the latest partner in the Millennium Seed Bank Project with Royal Botanic Gardens, Kew, London.

Other members of the international collaborative represent Western Australia, Burkina Faso, Chile, Egypt, Jordan, Lebanon, Saudi Arabia, Kenya, Madagascar, Mexico, Namibia and South Africa. U.S. participants include the Ladybird Johnson Wildflower Research Center in Texas and the U.S. Bureau of Land Management, Washington, D.C.

Seed is collected on expedition “in the field” according to strict scientific protocols after botanists first locate the plants. The Garden’s botanists are experts with knowledge of temperate plants of the region, and are familiar with the area’s locations of specific species. The seeds are then sent to England, where they are stored at minus 20 degrees Celsius, deep in huge underground vaults in the Wellcome Trust Millennium Building at Wakehurst Place in West Sussex. This preserves each seed’s unique characteristics and ensures its prolonged viability.
