Story : In the ninth episode of SuperQuark, the second documentary of the BBC series Monsoon Land. Just as the sea continually wets and dries the shore, the monsoon, after having discharged a large quantity of rain, changes direction and brings dry air (and drought) to the same areas. Animals have had to deal with this sometimes sudden change of season for millennia, and the lack of water creates crisis situations every time, where the weakest succumb. But men have also had to adapt to this pendulum for millennia, with their crops and their relationship with nature, and which today clashes with a development that is taking more and more territory away from certain animals threatened with becoming homeless: orangutans and Bengal tigers. Water, the most precious resource, is the molecule of life, but also one of the most critical resources on the planet.
