A little story. :) In my world Barubah appointed, we would never have done any harm to nature. Indeed, we will use anything to destroy it even if sometimes our crops failed, they were natural. In the other world with a lot of people and little room, people destroying forests to make fields. As if this were not enough, for better crops in record time, there was a ritual that was to use science to improve agriculture. However, there are consequences that do not seem to scare people in this world. We, the baruhiens do not confuse science with the environment as it is ridiculous. Even if that persons of the other world were still had benefits such as vaccines without injections, useful for those who were afraid of needles. There was also organ transplants from animals to humans. Unfortunately, it was not only the advantages and disadvantages are also numerous. We could include genetic pollution, the worst problem because it is irreversible as it is transmitted from plant to plant without that we can find a solution without seeing the naked eye.
