The PlanetXingu Project
Pt 1 • An Introduction to the project by Julian Dignall and its supporters want to raise cash to fund scientific research into the biodiversity of this region before its too late. The aim is to record the biotope and biodiversity before the river is permanently changed by man's activities. This may be a matter of months, not years. We may not know what we have lost if this research isn't carried out. The last remaining specimens may end up being those in captivity, so we want to find out as much about them in the wild as possible before it's too late. The clock is ticking, please help.
