Will you help Mother Nature save the Earth?

Environmental advocacy is going beyond the activists rallies. Individual responsibility and contribution to greenhouse gas emissions and climate change is being recognized. Will
consumer behaviour change to reduce consumption? Reducing the consumption of goods and services is a goal of environmentalists to achieve sustainability. What is the economic impact of the reductions? Who will set the global greenhouse gas budget? Will it be based on today's consumption per country or some future ideal "equitable" allocation of carbon dioxide equivalents.

Will we be forced to purchase carbon offsets as a new tax? Will the do-it-yourself crowd be allowed any thoreauvian-lifestyle deductions for their vegetarian diet or backyard garden?
