One thing I struggle with, with regard to leftist/pop-leftist approaches to environmentalism, is:
Our modern medical supply chain is dependent on fossil fuels to a boggling extent. Single-use sterile items; packaging for same; pharmaceutical precursors; etc. Obviously, defossilization of these supply chains is mandated --
but it's a hard problem. There are no quick or absolute fixes. So when I hear "just shut it down," I hear "my disabled brother is an acceptable casualty."
