European restaurants (in any EU country, even Germany) absolutely do use gas, and it's fairly common.
Depending on the restaurant, i'd go as far as to say "all" of them use it. At least the ones worth mentioning. Heating up hotdogs can probably done one something other than gas.
Fewer natgas stover in Germany, more in Italy. Netherlands has like 92% of households hooked up to natural gas. Restaurants are mostly gas or induction.
Populations of insects have collapsed, fish stocks have collapsed, biosphere is polluted by millions of tons of forever chemicals dumped into the Pacific ever year. Chemicals that keep accumulating in every life form.
Earlier puberty in girls by several years, lower testosterone in men by more than 50% in two generation. Intersex fish. Some species are even reproducing asexually which for some was thought impossible.
This is NOW. TODAY.
CO2 has become such a convenient misdirection device that the industry uses to keep your attention away from rather current things that can very well implode life as we know it well before any "climate problems" actually become disruptive as these all other pollutants are today.
Why else do you think Exxon is rated 100% ESG compliant? Yes! They bought some credits or whatever, but still dump a few million tons of actual pollutants that destroy life TODAY.
Just keep everyone spinning on the carbon hamster wheels.
