An editorial published in a special issue for the upcoming COP26 climate summit in Glasgow, Scotland states that treatment contributes significantly to "greenhouse gas emissions" and that this carbon footprint can be reduced if only "health professionals" can learn how to reduce "overdiagnosis" and "overtreatment".

Health care accounts for 4-5 percent of global greenhouse gas emissions. In the NHS, 62% of these emissions are associated with supply chains and 24% with health care. Healthcare professionals can be facility leaders that drive hospital decarbonization by reducing overdiagnosis and overtreatment in healthcare, eliminating waste, streamlining services, and better managing supply and procurement. All of these efforts will bring us closer to making health care more sustainable.

The desire to diagnose cancer as early as possible is another important factor affecting the carbon footprint of modern medicine. For several years we have been told to continually lower the cancer suspicion threshold, and we are calling for earlier and more thorough screening. In primary care, most patients with moderately high or even normal platelet counts are currently undergoing a flurry of tests in case thrombocytosis is an early sign of cancer. What should be the performance of these tests to make this approach acceptable? And shouldn't we take into account the environmental impact of having so many patients on the pipeline for various examinations as part of our cost-benefit calculations?

Isn't it nice? To make them get perfect life by "fighting for low CO2" you need to die from cancer.

Eating a predominantly plant-based diet, walking more, cycling and using public transportation will significantly reduce our greenhouse gas emissions and improve our health.

Animal products (meat, dairy products, fish) typically use much more land and water and generate more greenhouse gases than plant products. Sustainable and healthy diets consist primarily of a variety of plant foods that are low in animal products, unsaturated fats, and limited amounts of refined grains, highly processed foods, and added sugars. The nature and extent of the changes needed will depend on the existing dietary patterns of the local population. For example, to meet global dietary guidelines, the average meat consumption in Africa may increase slightly (2 percent), while in North America and Europe it should decline by 79 percent and 68 percent, respectively.

I propose to start eating capitalists, it will solve lot of problems, and it also will reduce CO2 emissions.
