Same thing applies to CO2: dumping it in the atmosphere is cheap right now because the policies to deal with that externality aren&amp;#x27;t quite there.&lt;p&gt;An obvious example of a policy that might help would be a carbon tax that makes more carbon-efficient things more economically appealing.</text><parent_chain><item><author>deltree7</author><text>Capitalism and Free Market.&lt;p&gt;On an individual basis, apart from zero-cost sustainable habits, if you are capable, become a master of science, attempting to solve energy, material, carbon and climate issue at a physics level.
