Thoughtful Thursday: Putting Freshwater in Focus

Published April 24, 2014

Every living thing requires freshwater to survive—and there’s not much of it. While a staggering 97.5 percent of our planet’s water is saltwater, only 2.5 percent is freshwater. And if you think that’s a small number, brace yourself, because it gets even smaller: We can access less than 1 percent of that freshwater. The rest of it is frozen and chilling, literally, in places like Antarctica and Greenland, or so far underground that we can’t get to it. water defines our world The freshwater we use exists in lakes, rivers, wetlands, reservoirs and in our soil. It’s replenished through rain and snowfall, making it a sustainable resource—if we use it wisely. This may come as a surprise, since many of us have seemingly unlimited water flowing out of our home faucets, but we have been taking advantage of it. Global water use doubled between 1960 and 2000, and the number of people living in water-stressed countries is expected to increase from approximately 700 million today to more than 3 billion by 2025. Half of the planet’s wetlands that supply our freshwater have been drained or destroyed, and less than half of the world’s longest rivers are free-flowing, meaning they’re not blocked by dams or other barriers. The good news is that there’s still time to change the future of our freshwater. If everyone pitches in, we can ensure there’s plenty of it for generations to come. Don’t believe you can make much of an impact on your own? Consider this: A bathroom faucet runs at approximately 2 gallons of water every minute. By simply turning off the tap while you brush your teeth, you can save 200 gallons of water a month. That’s enough water to fill five bathtubs! Turn the tide today. Use the 48 days between Earth Day (April 22) and World Oceans Day (June 8) to make a difference. All it takes is one small change in your routine, starting today.
