We identify sustainable sizes for a multi-agent system that consists of two classes of agents: one class is responsible for searching an area; the other for providing perimeter security for that area. In this context, sustainability means the ability of the system to accomplish the task while balancing shared resources. Bio-inspired rules based on the pride structures of African lions are devel...

The idea of sustainable cities is linked to an older concept of sustainable plant communities. The theoretical basis for both is a closed system where everything is continuously recycled. Natural resources are renewed rather than depleted. In undisturbed natural areas a kind of sustainability is achieved through the natural cycles of the biosphere. However, this kind of sustainability for trees...

Regulatory agencies and citizens have placed great emphasis on sustainability of natural resources. Individuals involved in animal husbandry should understand the basic components associated with air and water quality issues. An increase in regulations governing land, air, and water resources increases the need for educators, researchers, and producers to realize impacts of current and potentia...
