Any person that is irrationally obsessed with 'climate change', 'saving the planet', and reducing carbon emissions for Mother Gaia as soon as humanly possible via deindustrialization, even and perhaps especially at the expense of the production of any necessary goods or services (such as transportation and energy), that are reliant on the extraction of fossil fuels / natural gas / coal etc. It does not matter to them that these goods and services can not easily, if ever, be adequately replaced by 'green' renewables, and that any concerted attempt to transition to them while they remain unviable will cause a worldwide Great Depression as well as a massive drop in individual living standards.
They do not seem to know or care about furthering research into nuclear energy which is actual green energy by comparison to renewables, and have not bothered to do any research into molten salt thorium reactors which take the byproducts of uranium fission reactors and convert them into much less radioactive waste with a half-life of only 300 years instead of tens of thousands.
They are obsessed with recycling, and are usually activistic or at the very least tend towards some kind of climate activism, either by being outspoken about climate change, being a part of a climate group or green party of some kind, or both.
