“When people enjoy problem-solving as a means of self-validation and accomplishment, we must be watchful. What if they frantically construct situations to concoct solutions for problems they like to create? What if their solutions appear to make conditions worse than before? The white knights of the world improvers, who don’t hesitate to destroy nature and cultural heritages, can be a threatening problem on their own when they deteriorate the quality of our lifestyle and environment. ("Why step out of nature" ?)”
