People are capable of doing horrible things to each other, this is seen in recent wars. Sometimes, we think we are immune from such horrors. But human nature is that people will act on instructions from above to harm others. They will also do what it takes to survive. It is important, therefore, that we do not create a resource shortage on this planet, lest those propensities become more demonstrated. Protecting the environment is the best way to shield future generations of your family from such violence.
