Food quality dips as greenhouse gases increase
Science Daily says a field test conducted by the University of California-Davis "has demonstrated that elevated levels of carbon dioxide inhibit plants' assimilation of nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies."
Are Iowa’s proposed CO2 pipelines a legitimate climate mitigation tool?
Iowa environmentalists say the plan to build three pipelines to move liquified carbon dioxide — collected from the smokestacks of ethanol refineries — to North Dakota and Illinois, where the carbon would be pumped underground, will simply prop up the fossil fuel industry and shower their agribusiness investors with tax credits.
