Answer:
The quote "if you are fearful of the destruction of the environment, then learn to quit being an environmental parasite" simply means to be ready to sacrifice some of our usual necessities for the issues we feel strongly against.
Explanation:
The given quote "if you are fearful of the destruction of the environment, then learn to quit being an environmental parasite" is said by a farmer and environmental activist Wendell Berry in his book "Think Little". By this, he meant to imply that one must be ready to give up some of the pleasures of life if one wants a change in some issues that we strongly feel against.
For instance, if one wants to save the environment and make it better, then we must make an effort to not cut trees or burn wood, and also reduce the frequent use of our vehicles or fuels. By saying "quit being an environment parasite", Berry meant to say that to save the environment, a person must sacrifice the comforts of dependence on the environment like the destruction of trees or using fuel to produce more poisonous gases in the environment. This is like saying 'to save water, one must make sure to not unnecessarily wastewater and also make sure to preserve the water bodies while at the same time work in improving the water systems'. Like prevention or reduction of air pollution will require not only asking the government for better measures, but also an effort on our part to use less of our vehicles.
