The Arctic seas are being made rapidly more acidic by carbon dioxide emissions, according to a new report. Scientists from the Arctic Monitoring and Assessment Programme (AMAP) monitored widespread changes in ocean chemistry in the region. They say even if CO2 emissions stopped now, it would take tens of thousands of years for Arctic Ocean chemistry to revert to pre-industrial levels.
Producing a barrel of oil from the oil sands produces 3.2 to 4.5 times more greenhouse gases than conventional oil produced in Canada or the United States [1]. Extracting crude from the oil sands is incredibly energy intensive and consumes significant quantities of natural gas, electricity and diesel.
EWG partnered with CleanMetrics, an environmental analysis firm, to assess the greenhouse gas emissions associated with 20 types of meat, fish, dairy and vegetable proteins, as well as these foods’ effects on health.
