Freshwater Ecosystem
Freshwater is a precious resource on the Earth's surface. It is also home to many diverse fish, plant, and crustacean species. The habitats that freshwater ecosystems provide consist of lakes, rivers, ponds, wetlands, streams, and springs. Use these classroom resources to help students explore and learn about these places.

Sustainable Development Goal 6: Clean Water and Sanitation
In 2015 the United Nations General Assembly adopted 17 sustainable development goals designed to transform our world by 2030. The sixth goal is to ensure the availability and sustainable management of water and sanitation for all. According to the United Nations, one in three people live without sanitation. A lack of sanitation and sanitary waste management systems can reduce a community's access to clean water, and lack of access to clean water can allow diseases to run rampant, sometimes creating epidemics of water-borne infectious agents. Learning about how freshwater systems work in the wilderness, rural communities, and urban centers can help us better understand the challenges of providing clean water and sanitation to people around the world.

Freshwater Resources
This entry describes the unequal distribution of freshwater resources on Earth and how it impacts populations’ access to water, their economic development, and global geopolitics.

Using Fresh Water
Students explore maps to discover the distribution of fresh water resources on Earth, and they examine graphs to discover how fresh water supplies are used by humans.

Earth's Freshwater
Most people have heard Earth referred to as "the water planet." With that name comes the rightful image of a world with plentiful water. In photographs taken from space, we can see that our planet has more water than land. However, of all the water on Earth, more than 99 percent of Earth's water is unusable by humans and many other living things - only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers and swamps.The teacher guide describes our current understanding of water cycling and freshwater issues that affect natural and human communities.
