Von Wissenschaftlern ergriffene Maßnahmen zur Verhinderung des Klimawandels: Mit Politikern zusammenarbeiten, Interessenvertretung betreiben, Briefe an Politiker schreiben, zivilen Ungehorsam leisten, protestieren.

More than 1 in 3 researchers follows a mostly vegan or vegetarian diet?

That gives me doubt about the numbers.

Reversing it, rather than simply slowing the rate at which it is happening, requires everyone on the planet to stop producing and using a significant subset of the following conveniences:

* fire
* refined metals
* concrete
* electricity
* electrical appliances
* electronics
* health care
* mechanized farming
* mechanized animal husbandry
* mass-produced industrial chemicals
* synthetic medicine
* synthetic materials
* houses built with synthetic materials
* processed foods
* internet
* automobiles
* water treatment
* wastewater treatment

People and societies that already produce and use these conveniences must continue to produce and use them in order to prevent their infrastructure from decaying, their populations from rebelling, and their societies from collapsing. It is an unsustainable combination of a [tragedy of the commons](https://en.wikipedia.org/wiki/Tragedy_of_the_commons) and [arms race](https://en.wikipedia.org/wiki/Arms_race). It is a tragedy of the commons because everyone can sees the advantage of having it, can see that the barrier to entry is very low, and cannot see (or is unconcerned with) the collective long-term effects and costs. It is an arms race because those who have it are immeasurably more successful at survival than those who do not have it… in the short term.

No different than people with addictions that cause cumulative long-term damage. The short-term rewards are immediate, the short-term disadvantages for stopping are unpleasant, the long-term negative effects are crippling or lethal. No different than people smoking. No different than people drinking alcohol. The effects are gradual, but cumulative. Few people who start smoking, start drinking alcohol, start sun tanning, or do any other activity that causes permanent cumulative damage ever assume that they’ll get cancer, cirrhosis, or truly understand the emotional, financial, and social toll that those activities will have on them. They’re told that it’s bad for them, but they don’t understand it, intuitively. It’s a future problem to them that may never actually affect them as far as they are concerned, but the damage is there and is cumulative nevertheless, even if the effects are never so extreme that they are inconvenienced by them.

The problem is that as soon as you have some, you need more, and more, and it’s never enough are you are either unwilling or unable to go back because you’ve forgotten how, or because your society is not built to support such things, or because those who are willing to put up with the negative consequences and outlast the others will come out on top. It’s brinkmanship.
