Question

give the importance of the Great lakes of North America

Answer 1

The Great Lakes are a chain of five North American lakes containing the second largest accumulation of fresh water on Earth. Only the polar ice caps contain a larger percentage worldwide fresh water. This makes the Great Lakes an important freshwater ecosystem. Approximately 150 species of native fish reside in the Great Lakes, and because of this, the lakes have historically been an important part of North America's fishing industry. Unfortunately, fishing in the Great Lakes has greatly reduced as pollution and invasive species have depleted native commercial fish populations. This decrease in fish harvest is an important indicator of the overall health of the lakes themselves.
