Climate change and the 8 million people who die per year from fossil and renewable biofuel combustion products (WHO numbers) are far more concerning. Nuclear solves wayyy more problems than it causes.

Oh and nuclear fission used in breeder reactors is just as renewable as the fusion fuel in the sun that powers wind/solar/hydro/bio. We can make 100% of the world's primary energy for 4 billion years with nuclear before running out of fuel.
