Burning fossil fuels (coal, oil and gas) is the main driver of global warming, which increases extreme weather events (heat/heatwaves, bushfires, floods, cyclones, dust storms); air pollution; food and water insecurity; impacts the spread of vector borne illnesses; and disrupts health care delivery, all of which, directly or indirectly, increase the risk of CVD, writes Dr Fiona Foo, a clinical and interventional cardiologist and Co-Vice Chair Doctors for the Environment Australia NSW Committee.
