Talk:Amazon Rainforest
From Academic Kids
I thought the total surface of the amazonian forest was around 7 millions of km² (around 2% of emerged surfaces).
This article says 1.2 billions of acres. Given that an hectare is 2.47 acres. 1.2 billions acres is 480000000 hectares2, this is 4 800 000 km². Right ? Which is about half my value...
But I found numbers that indicated surface of the bresilian forest was about 60% of the amazonian forest, about 4 000 000 km² (with about a 10% destruction in the past 20 years).
I think there is a mistake in the article, and that the surface indicated is more the one of the bresilan forest rather than the whole surface. Ideas ?
- Amazonia and Amazon Rainforest are not the same thing. Although the rainforest is today the prevalent biome in the ecossistem, there are parts or cerrado and other forms of vegetatioin.
- Amazon rainforest is 7 million km² in size, Brazil is 8,5 million km² in size, and Brazilian amazon rainforest is 49% of Brazilian territory. Source: MRE (http://www.mre.gov.br/cdbrasil/itamaraty/web/port/meioamb/ecossist/amazon/)
Lígia (http://pt.wikipedia.org/Usuário:Ligia) In a book i read it said the complete opposite everyone says and believes in. The book states that trees relise carbon dioxide not oxygen if this statement is true the how come we are still living???
Number of tributaries
User:216.100.95.40 changed the number of tributaries of the Amazon from 1100 to 2200. I don't know the source for either number, but based on that anon's edit history, I reverted the change. Guettarda 17:13, 6 May 2005 (UTC)
And I reverted it again.Well, I thought I reverted it again - I didn't get an edit conflict but apprently you beat me to it. The same anon user had vandalized several articles within the space of a few minutes, then came back and reverted your revert. -- Gyrofrog (talk) 20:31, 6 May 2005 (UTC)
Economic value
One square kilometer in the Peruvian Amazon has been calculated to provide potential earnings of $682,000 per year if intact forest is sustainably harvested for fruits, latex, and timber..... If it was true it seems you would have to build a huge road network in the forest to get the income. In fact, wouldn't work on a huge network of roads be underway now?
- http://www.ecologyandsociety.org/vol6/iss2/art9/main.html this article questions these figures.KAM 16:34, 20 May 2005 (UTC)
- Also shouldn't it be vaule not yearly income?
