The
Dynamic Great Lakes
The five Great Lakes: Lake Superior,
Lake Michigan, Lake Huron, Lake Erie and Lake Ontario
with their connecting waters are the worlds' largest
system of water. They hold twenty per cent of fresh
surface water on this planet. Each lake differs from
the other and yet these connected lakes are one flowing
system connected to the Atlantic through the St. Lawrence
River. Unique ecosystems evolved in these lakes since
the last Ice Age but in the last 200 years commercial
fishing and the Lamprey Eel wiped out larger fish.
Shipping on the Great Lakes from all parts of the
world has brought exotic species that threaten to
topple food pyramids. Pollution carried through the
air and water damages life in and around these lakes.
Through knowledge, and the democratic process, The
Dynamic Great Lakes encourages us to appreciate and
understand these lakes and to get involved in finding
answers to their problems.
