The COVID-19 pandemic has been a nightmare for all of us. As vaccines are deployed across the world, many hope we’ll soon be able to return to our previous lives. But before we rush to resume ‘business as usual’, we should pause to consider where COVID came from.
Like many infectious diseases, COVID-19 has its origins in the encroachment of human activity into the natural world. As countries have sought to grow their economies, activities like logging, mining, road building, agricultural expansion and urbanisation cause massive habitat destruction.
This in turn has brought people into ever closer contact with wild animal species, many of which carry dangerous pathogens and diseases. When humans venture into ecosystems and destroy the habitats of wild species, these diseases can jump from animals into the human population.
