- The remaining 1% of freshwater is what humans and animals rely on for survival.
- Freshwater is found in lakes, rivers, and wetlands, with the largest concentration in the Great Lakes, which hold about 20% of the Earth's freshwater.
- The majority of the Earth's water, about 97%, is saltwater, making freshwater a rare and precious resource.
- Humans and animals need freshwater to survive, which is why they often live near freshwater sources like rivers, lakes, or wetlands.
- Without access to a natural freshwater source, humans must adapt to their environment by bringing water to them.
- Freshwater is essential for human and animal survival, making conservation crucial.
- The importance of freshwater conservation cannot be overstated, as it is a limited resource that supports all life on Earth.
