The COVID-19 pandemic has had a significant socio-economic impact internationally, with countries around the world being called upon to deal with uncertainty and fear in the face of an invisible threat.

The declaration of quarantine and confinement was the tactic followed in most countries, in order to achieve control of the disease. With the reduction of human activity, however, in just two months, an unprecedented impact on the natural environment was observed, which could teach us some things about tackling the phenomenon of climate change and reducing greenhouse gases.

During the quarantine, in major urban centers there was a reduction in air pollution, the sky seemed clear, the fauna was strongly present in public places with the appearance of animals and even wild species, while the noise was reduced to unprecedented for our time flat. At the same time, there has been a dramatic drop in greenhouse gas emission prices, given the huge cuts in travel, both on the road and by air.

But as life returns to normal, these prices rise again. In fact, there is a strong concern for a sudden launch at larger sizes than what we have been through so far. At this point, then, it is crucial to follow some critical lessons we have learned from this extremely difficult and unprecedented period.

One could say that the COVID-19 pandemic was a powerful shake-up reminding people that they are not omnipotent, and that climate change is perhaps the most important challenge to sustaining life on the planet with huge immediate economic consequences.
