Global Environmental Problems: A Nexus Between Climate, Human Health and COVID 19 and Evolving Mitigation Strategies

Global warming has increased the frequency and intensity of some extreme weather and climate events, and will continue to increase if no mitigation strategies are undertaken urgently. Climate change poses unprecedented threats to human health by impacts on food and water security. The increasing air pollution is promoting diseases. Water pollution and increasing secondary soil salinization is reducing agricultural production. There is a nexus between climate and COVID and there is urgent need to understand this nexus and act swiftly. Political and business leaders throughout the world have recognized that global climate change is real as evidenced by Paris Accord. However, there is urgent need of increased public engagement in adaptive and mitigative behavior. Moving the fossil fuel-based economy to decarbonization is major goal for achieving zero carbon emissions by 2050. Besides obtaining first-, second-, and third-generation biofuels, the agricultural and municipal wastes can readily be converted to bioenergy. Evolving green economies will result in human health benefits for mankind. This mini review will discuss nexus between climate change, health, and evolving mitigation strategies.
