Water is essential to life, and while we usually take it for granted, it is a precious commodity with a limited supply. Population growth, pollution, and climate change are leading to shortages of clean and accessible freshwater.

Water shortages have caused drought in California, rationing in South Africa, deadly protests in Iran and clashes among African countries. Water scarcity is already a big problem in countries with high population density. Per United Nations Environment Program, almost half the global population will be living in areas of high water stress by 2030.

President Biden’s infrastructure bill includes $55 billion for water infrastructure and other water system related investments. Investing in water could be a good long-term bet for those concerned about its sustainability. It is also a good option for environmentally focused investors.
