YES. If you consider the condensed explanation of sustainability related to ranching and agricultural practices, your definition would be; From Wikipedia: Sustainability is the ability of an ecosystem to maintain ecological processes, functions, biodiversity and productivity into the future. From the Commission on Environment & Development: In short, sustainability is “to meet the needs of the present without compromising the ability of future generations to meet their own needs”. We participate in sustainability by; putting abused lands back to native grass, returning the native buffalo back to its homeland, which in turn rejuvenates the ecosystem, as well as other native species, and we use limited fossil fuels in our ranch operation. It is our attempt at leaving our small piece of this world a little better then what we found it.
