Week 9 - Strong & Fragile Ecosystems

Ecosystems support generations of many different organisms. They make life possible for everything on earth excluding humans. They are fragile because they can be destroyed easily. in order to support that much life, they require a natural balance within. If a road is built through the middle of a forest or the ground is dug up to extract phosphate, it will destroy the balance and chance for life of the tiniest bug to the tallest trees. It is analogous to pulling one thread and unraveling a sweater but much more severe and once the sweater is unraveled it can't be knit back together.
