Ecosystem Population and Pollution
Although much of the Everglades is a protected national park, this has
not been always the case. Hazards caused by humans in the
Everglades are historical as well as an ongoing issue for its varied and
fragile ecosystem. Several of the hazards that affect the stability of the
Everglades’ ecosystem are environmental pollution, extracted resources,
habitat loss and destruction, and the biomagnification of toxins. Because
the Everglades is predominantly a marsh, these wetlands are an
enormous resource of fresh water. For nearly 200 years, humans have
been extracting fresh water from the Everglades for consumption and
agriculture. The irrigation of commodities such as oranges and sugar
cane can account for pollutants. Habitat destruction and loss can be
attributed to the introduction of non-native species as well as the
agricultural practices of humans. In addition, biomangnification increases
the prevalence of toxins throughout the food chain that can affect the
stability of the Everglades’ ecosystem.
Fresh water is the foremost extracted resource from the Everglades.
South Florida’s human population growth is putting pressure on the
Everglades to serve its increasing demands for fresh water. Building
dams and digging canals for agriculture and homes are a hazard to the
stability of the ecosystem. A great deal canals have been built, so the
natural flow of water is interrupted. “These changes in the natural water
flow as well as runoff from farmland brought about radical alterations in
the natural habitat, producing toxic algae, killing sea-grass beds,
