Rationing possible, but outright ban may hurt local population's income, so difficult for any political party to implement. Also, sadly in India, human capital and ecology has no value. Such a big disaster in uttarakhand and we are back to the same old practices. If a few hundred people perish due to over commercialization, we will do some lip service and continue the old way. I remember a meeting with a pharma supplier a few years back. On the outbreak of some virus, he told me that your government is inhumane. He told me, When a few people died in France, the government initiated some national emergency, halted all negotiations and procured the vaccine at whatever was the quoted price, whereas, the indian government stuck to its stance, wanted a lower price, higher kickbacks for the procurement of the medicine. We have such a huge supply of human capital, that a few deaths won't budge the government, unless its the uber rich, who are at risk.
