Thomas Szasz has a (good) theory that we all need something to worry about. This may or may not be true or true at different levels depending, or could be called creative tension or whatever else. Just like stereotypes and rumors. Isnt there alot of (but no absolute) truth to the things we say and believe?
Environmentalists of course worry about the environment. And of course some environmentalists are 'leftists' because they want to take money from some people and give it to causes they believe in, in of course this case, the environment. And to put this redristribution ahead of the rights of others to keep the fruits of their labor. This takes form in asking the government to do things against "polluters". (But dont we all pollute and is not repeting the obvious or exagerating the truth pollution as well?).
Ok then, well it seems like now the market is helping to solve the problem of regulation oftentimes keeping the prices of resources too cheap which then leads to an over depletion of these resources. Point is people are asking for factories that dont pollute or waste water and or energy. Companies are hearing the demand (and reacting to the high price of oil), witness Frito Frtito Lay's prototype Net-Zero factory. Don't worry about it and be sure to buy their potato chips if you like the idea, and well, like potato chips.
