As a reminder of that important point, here’s Don Boudreaux:
What we almost never hear from self-proclaimed “environmentalists” is recognition of the upside of contemporary life. The commerce and industry that produce all the things that environmentalists ecstatically despise also produce incredible amounts of wealth, health and cleanliness — not to mention the leisure necessary for modern people to reflect upon and enjoy nature.
Also, too many environmentalists condemn people who don’t share their creed. For example, I don’t recycle my trash because my time is too precious for me to spend it sorting such items into different containers. I never criticize those who do recycle, but environmentalists point accusing fingers at us nonrecyclers. In environmentalists’ eyes, those who unquestioningly disregard the value of one resource (time) in order to spend it on the conservation of other resources (wood, plastic and glass) are righteous while those of us who value and conserve time are sinners.
