The document discusses several key aspects of agricultural sustainability. It first discusses definitions of sustainability from the Brundtland Commission as meeting needs of the present without compromising future generations' ability to meet their own needs. It also discusses the concept of intergenerational justice and whether current generations' use of resources unfairly burdens future generations. Additionally, it outlines Aldo Leopold's land ethic which argues people should regard land as a community we belong to rather than a commodity and should use it with love and respect for all parts of the land community.
