> I get pushback on this opinion from my friends, so I expect this to be an unpopular opinion here also: the cost of meat should be priced to also cover external costs of water and harm to the environment.

Maybe that would have some kind of effect, but what exactly?

Greenhouse gas emissions by sector:

https://ourworldindata.org/ghg-emissions-by-sector

> Energy: 73.2%

> Agriculture, forestry and land use: 18%

> Waste: 3.2%

> Industry: 5.2%

Each piece of the pie is further broken down and so you can see that, for example:

> Agriculture etc > Livestock & manure: 5.8%

> Energy > Food and tobacco: 1%

The majority of emissions comes from burning fossil fuels. Additionally, fossil fuels produce gases that were buried in the soil for aeons, whereas meat production produces gasses most of which are re-absorbed by the soil. See carbon cycle:

https://en.wikipedia.org/wiki/Carbon_cycle

To be more specific, as the article says:

> Livestock & manure (5.8%): animals (mainly ruminants, such as cattle and sheep) produce greenhouse gases through a process called ‘enteric fermentation’ – when microbes in their digestive systems break down food, they produce methane as a by-product. This means beef and lamb tend to have a high carbon footprint, and eating less is an effective way to reduce the emissions of your diet.

So cutting down on meat is an effective way to reduce the contribution to greenhouse gas emissions of your diet. Your largest contributions are your (direct or indirect) use of fossil fuels.

Furthermore, the majority of eemissions in meat production come from ruminants. Chicken and pork should are not ruminants and you should probably exclude them from your taxation suggestion.
