In 2016, the Harvard biologist emeritus and naturalist E.O. Wilson (TED Talk: Advice to a young scientist) published Half-Earth: Our Planet’s Fight for Life, in which he proposes that half the earth’s surface be designated and protected as conservation land. Just since 1970, human beings have destroyed more than 30 percent of forests and the marine ecosystem, according to the World Wide Fund for Nature. The destruction has been an unintended consequence of population growth, the desire for increased material wealth and comfort, and the associated need for more energy. It’s also been driven by the inexorable imperative of capitalism and the powerful desire of certain individuals to increase their personal wealth. Wilson’s proposal might be difficult to achieve, but it represents a recognition of the importance of our natural environment and the forces that threaten it.
