If those with the power to make a difference don't make one, how can we make them?

I agree with Professor Maniates that books entitled "The Green Book: The Everyday Guide to Saving the Planet One Simple Step at a Time" are dangerously misleading since the environmental crisis we are facing currently has no simple solution to it. Still, I see a value in them in that they are a good way of raising awareness in people uneducated on the topic.

I also agree with Professor Maniates' when he says that "we need to be looking at fundamental change in our energy, transportation and agricultural systems rather than technological tweaking on the margins." However, this is a hard task, mostly because positive efforts and good intentions are choked by the socio-political system in place. Therefore, even though "a slowing of the growth of environmental damage" by "tweaking on the margins" is " hardly enough," it is also essential as it will save us precious time that is needed to find a realistic drastic solution to the crisis.

I have a hard time imaging how a drastic solution can be adopted considering there is still a large portion of the population that is unwilling to make small changes such as driving hybrid cars, installing solar panels in their households or even the smallest change such as switching to energy efficient light bulbs. That being said, I still think we should change the system so to stop people from destroying the planet. I'm just not sure how at this point. And with so many "lazy" people in developed countries, it's hard to be positive on the topic.

How can we get to the political and corporate giants and get them to put in place the fundamental changes we want to see happen??
