In some parts of the world, marginal quality land is used for monocropping of animal feedstock using intensive exogenous inputs (fertiliser and pesticide).

Raising animals for meat on meadowland, depending on the level of intervention used on that land, can actually be good for biodiversity although if those animal are excreting larvicides everywhere they go, it's not so good.

In the English context, the richest habitat with the best biodiversity is a complex mix between meadows, hedgerows, and woodland. The exact historical balance, especially between meadows and woods is hotly contested and an open research topic.
