What will the world be like for your grandchildren - and their grandchildren - if tigers disappear from the planet? Or sharks? What will their planet be like if Nectophrynoides asperginis goes the way of the dodo?

That last was a trick question; N. asperginis - the Kihansi Spray Toad...

The fishers of the world are fighting mad. Rivers and the lakes they feed are drying up, partly due to climate change and drought, but also because large dams are holding back their waters.

These formerly self-sufficient people want their rivers back, and they're making noise about it around...
