The Sierra Club was famously pro-nuclear back in the river damming days for hydroelectric power.
They were also decidedly anti-immigration. Their major donors put a stop to that, and they have been silent on that elephant in the china shop ever since.
So it’s interesting “environmental” groups are now in the business of importing more people - who increase the need for services, roads, electricity, and impact our “carbon footprint”.
If you really dig down, everything the leftist does is total BS.
Yep, the Sierra Club is now a quiet but very extreme radical communist organization.
