This week marks the 19th year of World Water Day. The United Nations Conference on Environment and Development designated this day as an annual international event focusing on the importance of sustaining and managing fresh water resources. This year’s theme is water and food security. This is such a critical issue to not only to our international friends, but also for U.S. farmers, ranchers, growers, consumers, and conservationists.
