Re eating meat. My husband is a farmer whose family gave up their beef farm 40 years ago, so he has never farmed animals. They only have crops.
there is a huge decline in soil quality after 40 years of not rotating cattle or sheep on it. There is less actual soil and less nutrients in the soil.
they try adding manure, but all the farmers with animals use it themselves for their own fields and human manure has it’s own issues with medication etc so isn’t suitable either.
so they have to resort to fertilisers which are made using fossil fuels. And they do not put organic matter into the soil.
they also try other things with cover crops etc that I won’t blabber on about, but they are seriously considering getting a roaming sheep farmer to add into the rotation.
other benefits of grazing livestock is the grass they eat is a fantastic carbon store, their hooves also trample the ground to lock in the moisture and encourages the grass to grow (farmers replicate this through rolling) and we are only just beginning to understand the benefits of the micro biome relationship in their gut and the roots of the plants they eat and the soil. Taking animals out of the equation is not good for the environment.
other reasons why we need livestock to benefit the environment:
-if a crop is bad due to bad weather or for other reasons, it cannot be sold for human consumption, but it can be given to animals, turning a crop that would have ended up in the bin into food. (If you eat the animal)
-food waste like uneaten salad leaves and slightly off veg can be given to animal’s too.
-there are many areas that are unsuitable for cropping, like lots of areas in Devon/wales/highlands due to the terrain, but perfect for sheep and cattle.
-meadows where livestock is grazed is often wonderful for the environment, biodiversity etc. monocropping, while necessary is not good for biodiversity.
just some things I never knew if you’re interested x
