ABSTRACT
According to physics principles, any action produces a reaction and generates consequences. Under this premise, it is essential to reflect on the actions we have in our relationships with other animals in current times. Our actions always bring implications, in many cases, affecting the welfare of animals, humans, or the planet. A unique virus, COVID-19, caused a pandemic, with more than 50 million cases in 188 countries as of November 2020. Evidence indicates its spread was a consequence of the human relationship with wild animals used for marketing and consumption, generating radical changes in social and economic dynamics, and significantly impacting animals. The lockdowns slowed down daily life, forced stop using vehicles, and reduce our excessive consumption of things. In just a few months, nature has shown that fauna can return to places where it had not been present for decades, the water cleared, the air cleaned, and a kind of natural balance returned. During the forced human quarantine, the outlook for production animals showed the fragility and low resilience of high-density industrialized systems. The excess of animals in contrast to the low number of processing plants (large in size, and therefore fragile when facing a problem like this) resulted in the emergency slaughter of millions of animals on farms. In the case of companion animals, they have suffered collateral damage due to conscious or involuntary relinquishment due to cities' surprise closures;additionally, humans' constant presence at home has generated multiple behavioral problems. For animals in zoos, the situation is also difficult, as visitors' absence reduced incomes;it has put many zoos around the world at risk of closure. The impact of the COVID-19 pandemic on animal, environmental, and human welfare is clear. Hence, the objective is to analyze the impact of the pandemic on global welfare.
