Steps to sustainable livestock
Global food security has become an increasingly important issue as climate change further reduces the amount of land available for farming. Coupled to this is the higher demand for animal protein as developing nations become wealthier, and a higher demand for cereals, making them less attractive as animal feed at both an economic and social level. This has resulted on a greater emphasis on ruminant farming (e.g. cattle and goats) because these animals are capable of converting feed unsuitable for human consumption into high-value protein.
