Is a promoter exempted from any liability arising out of his actions?
They engage in business to survive as a livelihood, to make money to provide services and merchandise to others etc.
Obviously in a free market economy unless a business provided something that was needed they would not survive.
For every action there is a reaction. The question is how harmful or beneficial the outcomes are.
Truthfully the environmentalist are probably going to end up leading this country into the next great depression, that could be global at the rate environmentalist are going. And they do not care, it seems they care more about Polar Bears who have actually more than tripled in population than they do man. The same thing aplies to a particular fish, or turtle etc. and what is the worst about these special interest groups is that they DO NOT use actual scientific evidence but media hype instead. All the while they set a back drop for governments to have excuses to take land rights away from people. Throughout history it has always been about LAND and money. Controlling LAND as in individual property or continents, is the driving force behind theenvironmentalists. Sure the environmentalist wish to control how land is used, but governments see the opportunity from that to further control not only use but value. Once VALUE is diminished because use has been forbidden government can get the land back for either a song or a donation )to avoid taxation on non-usable land by the owner). Than government can re zone and do what they like. So all this hype really has economic gain, and environmentalists are as in on it as Government officials. The sad part is that the average person does not understand what is really going on. Before you make up your mind about what I have said why not take a read of these links?
