A reasonable reading of these results is that a lot of environmentalists experience many aspects of the modern world as chaotic and thus seek to compensate for their perceptions of disorder by engaging in ritual behaviors that make them feel like they are exerting more personal control. It is not much of a leap to conclude that by imposing those rituals on others, some environmentalists seek to reduce their dread of disorder even more.
Why call them rituals? Because it is not all that clear that they actually do anything much for the natural environment. For example, the costs of curbside recycling often outweigh purported benefits, and lower organic crop yields mean more land taken from nature. But as Meijers and Rutjens have shown, partaking in such rites is much like reciting the Rosary, in that they, too, reduce participant anxiety.
Environmentalists are nuts
