The biggest and heaviest seed in the world is that of the Seychelles coconut. It can weigh as much as 30 kilograms (66 pounds).
Forget rainforests
Forget rainforests Rising levels of greenhouse gases have led to
faster tree growth in arid regions due to the larger amounts of
carbon dioxide available to trees in the atmosphere. Trees combine
water with carbon dioxide to grow and the abundance of carbon
dioxide is making this process more effective. Planting forests in
dry areas to combat the effects of global warming is now being
considered. Although desert trees grow slowly, at between one-tenth
and one-quarter of the rate of tropical rainforests, the large
amounts of land available for tree planting in arid countries
should not be ignored. Planting more trees could help to reduce the
amount of carbon dioxide in the atmosphere, helping to balance the
Earth’s carbon budget. 2 OCTOBER 1999, P. 25
