Abstract

The ongoing coronavirus pandemic has killed hundreds and thousands of people and led to the astonishing lockdowns which have relentlessly pushed the world economy into recession. We find that the origin of coronavirus is related to the increasing marine viruses with ecological evolution and natural selection. The marine viruses have already killed their hosts every day, reduced marine biodiversity and affected marine ecosystem and food webs. The “intermediate host” could be bats, pangolins, rats or other animals which passed the marine RNA viruses to humans. The climate change has already posed threat to the harmony and balance of natural ecosystem. Although the coronavirus pandemic has helped to reduce the carbon emissions temporally, we discover that the air pollution and climate change could still make significant contribution to the outbreak and high mortality rate of COVID-19 pandemic. It is urgent and necessary to improve the climate, ecological and epidemiological models with including viral processes for the better predictions of future emerging virus pandemic, air pollution and weather extremes.
