WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
Globally, agriculture uses the highest percentage of freshwater, accounting for about 70% of total water withdrawals. While most of the water goes to irrigation, it also helps provide the energy and ecosystem services required for farming. 随着地球人口的增长和消费模式的改变，经济繁荣, global demand for food will increase. 淡水鱼也是世界各地数百万人蛋白质和生计的重要来源.
Nearly every business is water-dependent in one way or another. In 2014, 世界经济论坛的年度全球风险认知调查将水危机列为全球十大最令人担忧的风险的第三位. 水资源短缺和水质差的问题已成为严重和日益严重的社会问题, environmental and economic consequences. And although water risk is rising quickly on the agenda of business and investors, many businesses are just beginning to understand what fresh water means to them, their profits, and their company’s long-term viability.
Clean, fresh water is an essential ingredient for a healthy human life, but 1.1 billion people lack access to water and 2.4 billion don’t have adequate sanitation. 水不安全和卫生设施不足导致的疾病每年造成的死亡人数超过所有形式的暴力, including war. The situation is predicted to get worse: by 2025, two-thirds of the world’s population may be facing water shortages. 可持续地获得淡水和卫生设施可以使人民更健康，促进经济增长, which facilitate improved environmental management. In other words, healthy communities help preserve a healthy planet, and a healthy planet is the foundation for healthy communities.
Energy and water are interdependent. Energy is required for pumping, storing, transporting and treating water, and water is essential for producing almost all kinds of energy. While the role of water in hydropower is obvious, water also irrigates biofuels, plays an essential role in fracking, and cools thermoelectric power plants like coal, nuclear, natural gas, and oil. 所有这些能源生产方法都可能造成严重的环境和社会后果.
Freshwater ecosystems cover less than 0.01% of the planet’s total surface area but they support more than 125,000 species, from fish to terrestrial animals. They also provide a myriad of ecosystem services, including helping to regulate the temperature of the land and sea, creating clouds and affecting the weather, transporting nutrients and minerals, and keeping nature clean and healthy by dissolving pollutants and sediment run off. However, more than half of the world’s wetlands have disappeared since 1900, 在世界177条最长的河流中，只有不到70条河流没有人为的障碍.
