Veg*nism simply pushes the killing to where it can't be seen! There is still death and destruction with modern arable farming practices.
Go look at a farmed piece of monocropped land. It is a chemically cleansed monoculture (and that is at the height of growth prior to harvest). After the harvest the soil is exposed, eroded and leeched of nutrients which (in intensive Western farming) requires amonium nitrate fertiliser to redress. The toxins used to cleanse the land kill bug life and wash off (along with the soil) to kill aquatic life in the water cycle.
In contrast look at arable pasture. Biodiverse and rich in life. The animals are drought/flood tolerant (unlike crops). Larger animals with large fat stores can tolerate famine. If the weather turns nasty, animals can be herded to safer areas (unlike crops).
More interestingly animals can be used to restore the land - implemented as part of the life cycle and general health of the land.
Two examples of this can be found here:

Here is a recommended reading list that shows how animals can be used as part of your food cycle:
- "Meat a Benign Extravagance" by Simon Fairlie
- "We Want Real Food" by Graham Harvey
- "So Shall We Reap" by Colin Tudge
- "The Power of Duck" by Takao Furuno
- "The Carbon Fields" by Graham Harvey*
