Which is the best description of how an environmentally sustainable society manages its resources? 

A)  it satisfies the needs of its people by harvesting without depleting Earth's capital 
B)  it focuses on all levels of society having sustainable incomes 
C)  it satisfies all society's needs by not harvesting any new materials 
D)  it focuses on today's society's needs and the needs of endangered species

An environmentally sustainable society manages its resources by satisfying the needs of its people while ensuring that the resources are harvested without depleting Earth's capital. This approach ensures that the needs of the current generation are met without compromising the ability of future generations to meet their needs. Option B is a part of sustainable development but not the best description of managing resources. Option C is unrealistic as a society cannot satisfy all its needs without harvesting any new materials. Option D is insufficient as it only focuses on the needs of today's society and endangered species, not the long-term sustainability of resource use.
