Trees and Pollution, Continued
Not only do trees cause pollution, but pollution causes trees.
Acid rain from Britain has caused Norwegian forests to spread.
Apparently, pollution is even better when it's globalized.
British acid rain is good for Norway's trees, says a Norwegian scientific study.
It wipes out damage caused by pollution from local industry and has helped the country's forests spread by a quarter in recent decades.
The report, by the state-run Norwegian forestry research institute, says that acid rain has been unfairly demonised.
Svein Solberg, of the institute, said: "After 15 years' research, it is now clear to us that, as far as forests are concerned, our fear of acid rain was totally unfounded.
"What we have found is that Norwegian forests have had a growth rate of some 25 per cent over the past 15 years and that acid rain is the reason."
