What Does Sustainability Mean?
Sustainability is a landscape or plant environment
that can completely care for itself independently with the available natural
resources. Sustainable biology includes
enough diversity that it can continue indefinitely.
Marshes, forests, or wetlands are all considered
sustainable biological environments.
Sustainable biology is able to thrive without any
human intervention for decades or centuries.
Maximum Yield Explains Sustainability
Sustainability requires a biological system rich with diverse plant life that all perform a specific function in order to
sustain an environment. A marsh, for example, includes cattails for filtration
of groundwater, grass which provides the biological material for the marsh when
it dies and rots, and flowers to attract bees and other insects.
Sustainability requires the diversity of plant and
animal life to endure the many environment conditions that occur throughout the
year. A biological system that is sustainable is able to survive and thrive
during the wet, rainy months, and endure long periods of drought.
Sustainability in residential landscapes requires
careful planning to select a variety of plants so the garden will be able to
collectively care for itself and thrive without human intervention or
artificial watering and fertilizing.
