HIV, Ebola, SARS and Now COVID-19: Why Some Scientists Fear Deadly Outbreaks Are on the Rise

The social upheaval and death caused by the new coronavirus has awoken many to what some infectious-disease experts have been warning about for more than a decade: Outbreaks of dangerous new diseases with the potential to become pandemics have been on the rise — from HIV to swine flu to SARS to Ebola.

Many experts now believe that this surge in new infectious diseases is being driven in part by some of humanity’s most environmentally destructive practices, such as deforestation and poaching, leading to increased contact between highly mobile, urbanized human populations and wild animals.

“The evidence is clear; we’re driving disease emergence through less sustainable use of nature,” said Dr. Aaron Bernstein, interim director of the Center for Climate Health and the Global Environment at the Harvard School of Public Health.
