    The Green Revolution was established in the 1960's as a plan to increase crop yield by using technology to grow and cultivate crops.

    The Tragedy of the Commons is when a person or persons degrade an environment by overgrazing and overexploiting resources for their own advantages and usually at the expense of others and future generations.
