The findings could have serious implications for the environment. Scientists made their discovery when investigating the effect of de-forestation of the Amazon basis on carbon dioxide levels. ——————————————————————————————————1/6—— by Serena Hennessy WIN A HOME CINEMA TV p465 Poison?

The vast areas of Amazon forest destroyed in the past 30 years should have meant sharp rises in the levels of carbon dioxide. But it seems the remaining trees have been slurping up more carbon dioxide - and growing bigger and faster on it. ——————————————————————————————————2/6—— Fun and Games 150 Bamboozle 152 ARE YOU BEING POISONED? p163 Poison?

Dr Yadvinder Malhi, of Edinburgh University, said the trees' increased growth was almost certainly due to higher levels of carbon dioxide. ——————————————————————————————————3/6—— WIN a home cinema TV 465 CHEESY POTATO TORTILLAS p164 Poison?

Researchers found the remaining trees in the Amazon forest were sucking up huge quantities of carbon dioxide.

"Each acre would have to absorb an additional 20 tons of CO2 to increase that much." ——————————————————————————————————5/6—— Eco Scene 148 Love Stars 418 WIN A HOME CINEMA TV p465 Poison?
