How can you say that you do not contribute? Maybe not to this specific reserve in canada. Every single thing you own, every single tool you use, every single source of energy you consume had to come from the environment and its resources. So tell me how you can be so sure that,for example, in the processing of your keyboard that you type this shit on a squirrel wasn't killed?
I hate destroying of the environment also, but you seem to only equate it to those who produce the oil, not those who consume it. Humans are not the only species who change the course of nature. What about a beaver colony who builds a massive damn and destroys the eco system down stream? Or destroys what used to be a marsh land, but now its a pond or a lake. Do you hold them accountable for killing thousands of spotted frogs? Or do you say its okay because they need a place to live, just like humans?
