COVID-19: Should we care about the environment in the midst of an economic crisis?

Our planet may be fittingly compared to the 1994 film, Speed: A bomb is planted on a bus and rigged to explode when the bus slows to less than 80 kilometres per hour.

I discovered neither fanaticism nor nervousness, neither doubt nor ideological speech in Roth, an octogenarian who still looks in detail at each new subject appearing on the agenda of the debate between evolution and creation.
