What do people no about tribes in the Amazon rainforest?

Hello if you go to www.google.com and type in - tribes in the Amazon rainforest - you will come up with lots of answers. including this one - http://www.amazon-rainforest.org/indigenous-tribes.html - By the way the word spelled "know" comes from the word "knowledge". The word spelled "no" means yes or no. Enjoy your homework maybe someday you might like to go and see the amazon. There is also a movie called "At the End of the Spear" It shows neat pictures of the Amazon. Hope this helps.
