Last December, in the city of Wuhan, China, a virus usually linked to animals was transmitted to a human for the first time. The coronavirus COVID-19 comes from the same family of viruses that usually affects the respiratory tract. It is in the same family as the common cold, the flu, and other more serious respiratory illnesses. When humans are infected with COVID-19, they experience symptoms such as fever, coughing, and difficulty breathing similar to pneumonia.

In 2019 and 2020, the south of Australia faced wildfires that destroyed everything on their paths. Between September 2019 and January 11, 2020, 28 people have died in those fires and many more have gone missing. According to a study by the University of Sydney, 480 million animals have also perished in these fires.
