Everyone on earth should have access to safe and affordable drinking water. That’s the goal for 2030. While many people take clean drinking water and sanitation for granted, many others don’t. Water scarcity affects more than 40 percent of people around the world, and that number is projected to go even higher as a result of climate change. If we continue the path we’re on, by 2050 at least one in four people are likely to be affected by recurring water shortages. But we can take a new path – more international cooperation, protecting wetlands and rivers, sharing water-treatment technologies – that leads to accomplishing this Goal.
