Culling Cows?

Eire (Ireland) has 7.3 million cattle. In recent years, that country's 'greenhouse gas' emissions have continued to climb. 37.5% of Ireland's national emissions come from agriculture. This is the highest proportion in the EU. Highly potent 'greenhouse gas', methane, from belching cows, makes a major contribution. Ireland's emissions cannot consequently be effectively reduced, without agriculture making a major contribution (https://www.theguardian.com/world/2022/aug/29/irish-farmers-cull-cows-meet-climate-targets). By 2030, the Irish government wants cuts of emissions from agriculture; transport and commercial/public buildings, to be respectively 25; 50 and 40%. Irish farmers are not at all happy. They claim a cut this size, will drive many farms to bankruptcy. They may even be forced to cull some cows. The Irish farmer's objectionss are emotive (and understandable) but the world cattle population will have to be substantially reduced, if this planet is to remain a viable option for humans and many other lifeforms. There actually seems little option for Ireland, other than cutting back on cows!
