According to a research at Cambridge University supported by the European Research Council there is a correlation between the emergence of Covid-19 and Global Warming. 

As a matter of fact the climate change in the forests of southern China would have caused some ideal conditions both for bats and for  the outbreak of the SARS COV2 and its spread.

In the south of China, in the  regions of Myanmar and Laos, the global warming has completely changed the environmental conditions. Many species of animals have been forced to migrate to other areas in search of more favourable conditions. This is what exactly happened to bats, for example.  The increase of temperatures, sunlight and carbon dioxide have made those places ideal habitats for bats: the number of bats has increased  by 40% in those areas compared to the previous century.

Actually, in the world it seems that there are about 3000 different types of Coronavirus carried by bats.

The loss of a natural habitat forces animals to migrate and contact other animals or people and share germs and, for this reason,  the migration of bats has increased and modified interactions between animals and pathogens which have led to the development of the virus and to the Covid-19 emergence. . 

According to these theories , the Chiroptera (the scientific name for ‘bat’) and the climate change  may be the causes of the spread of such a dangerous virus that has left the whole world immobilized.

However, there is not a real conclusive evidence that weather and climate have a strong influence on transmission: in fact the SARS-CoV-2 virus which causes COVID-19 disease has been transmitted in all regions of the world, from hot and wet  to cold and dry climates. On the other hand, climate change is an important element to consider because it is true that it alters  the way we relate to other species on Earth and this influences our health, too. 

For this reason we have several reasons to take climate action to improve our health and reducing risks for infectious disease emergence is one of them.

What could we do then?

It is important to  take climate action to prevent the next pandemic. For example, preventing deforestation can be useful to keep biodiversity loss under control as well as slow animal migrations that can increase risk of infectious disease spread.

Moreover, reducing air pollution caused by burning fossil fuels like coal and oil, for example, helps keep our lungs healthy, which can protect us from respiratory infections like Coronavirus.

We may be more or less sceptical about  the ‘link’ between climate change and Coronavirus disease but what we do know for sure is that guaranteeing and ensuring  the environmental elements of health (for example, safe and nutritious food, clean water and air, sanification) leads to an essential protection against all health risks. 

For all of us.
