Well, equally if you've no intention of cutting down any further, why are you here? It's almost as though no one is here because they plan to cut down, which is the point of the thread, isn't it?
I think there are a lot of issues here. It doesn't easily reduce to a tweet-length answer.
1. Regarding health:
Cutting down on the absolute amount of meat (and I include fish in that). Changing the kind of meat you eat - not just red vs white, but perhaps more importantly, fresh vs processed. Changing the way you eat that meat - it's not just about frequency of meat consumption. And of course, dietary health isn't all about meat - what of all the other things we're eating.
2. Regarding animal welfare:
Clearly, issues of free range/battery, but also realism about how embedded and intertwined our animal-product-consuming systems are. As funky monks was keen to point out, the dairy industry and the beef industry are aspects of the same industry. Whether you eat free range or barn-kept chickens, male chicks still get put through the shredder. Regarding transport and slaughter, what levels of knowledge or control can we have over these?
3. Regarding the environment:
The question 'how should we farm?' What can and can't be sustained long-term? What does sustainable farming look like and realistically what would our 'fair share' look like within that system? How do we balance potentially competing interests and make healthy, sustainable diets something everyone can achieve?
Number 1. is ultimately largely within our own agency, allowing for the limiting factors of income, time and energy to devote to food, living in food deserts, etc.
Numbers 2. and 3. are only partially under our control, mostly not, even with our best efforts. What kinds of changes would we like to see and how do we get them? What is the place for individual action vs collective action? What does that collective action look like? And lastly, not unimportantly, what alliances are we prepared to make with others to effect change for the better? Who are the common enemies here?
