Depending on human actions, the life cycle of an aluminum can may be linear or circular.
If we throw away our aluminum can in the garbage, that can has reached the end of its life. Instead if we recycle, that aluminum is used again creating a completely closed loop cycle.
Compare the closed loop of the recycled aluminum can to the closed loop of the zebra longwing butterfly life cycle.
Consider other natural cycles impacted by our daily lives. Learn more about these systems to find ways you help to make cycles circular instead of linear.
The Water Cycle
The Everglades ecosystem has been impacted by changes to the water quality, quantity, timing and distribution throughout the region. The South Florida Water Management District
is responsible for protecting the water cycle of the Everglades.
The Phosphorus Cycle
The Everglades are naturally a nutrient poor ecosystem. Humans have added excess amounts of phosphorus to the ecosystem indirectly. The use of large amounts of phosphorus for farming and landscaping has had serious consequences in this fragile ecosystem. Learn more at Friends of the Everglades
. This foundation was created by Marjory Stoneman Douglas, the mother of the Everglades.
