You live in a village but your original source of water have diminished.
There is a river just through a jungle, it is possible to divert it for your own benefit and draw it closer to the village. Closer to the village means less danger for the villagers but it also means that the natural life near the river will die.
What is more right, to divert the river so that you and your own can live safer? or to let it stay where it is and travel to it with the risk of loosing members of the village?
A third question is: Change is inevitable, but ought one to seek it? or let it fall where it may?
Why do you think the animals will die? They are capable of finding water.
