Big business- Lake Erie

Because of its social, environmental and economic importance, shouldn’t you know more about Lake Erie and how you can protect it? By joining us here each Tuesday, you can learn about avoidable problems and what others are doing to protect our freshwater resources, including Lake Erie. The Lake Erie watershed is home to about 13 million people, supports one of the largest freshwater fisheries in the world and provides many recreational and tourism opportunities.

Act now: limited supply

A closer look at Earth from space reveals an immense shared system of freshwater lakes that are connected to each other and to the world ocean by the water cycle. The Great Lakes — Superior, Michigan, Huron, Erie and Ontario — and the rivers, channels, and smaller lakes that feed or drain them make up the largest surface freshwater system on Earth.

Into the deep end

Pinpoint where you live. Whether it’s near a coast or hundreds of miles inland, the water cycle connects you to the ocean and all the water in rivers, lakes, under ground and in the atmosphere. A fixed amount of water goes around the Earth in a perpetual cycle to keep us alive but the activities of an exponentially growing population are bringing this complex water system to the brink of collapse.

The water cycle

However infinite our water resources may seem, there is only a fixed amount. Water goes round -and-round the earth in a perpetual cycle, connecting all life on earth past, present and future. The water that makes all life possible today is the same water that kept dinosaurs alive. Only 3 percent of the earth’s water exists in reservoirs, outside of the ocean – in ice, the atmosphere, groundwater lakes, rivers and living things.
