Water quality

Water is a critical resource for life on earth!

We use water for many purposes, not just drinking and washing. The stewardship of water rests on all of us, but especially those who grow our food. Inputs to food production systems may not always stay put. Growers are continuously addressing concerns of fertilizer run-off and soil erosion. This set of materials helps illustrate how water is affected by human activities, one of which is food production.

Aquaculture

How are fish benefiting from soy feed? The global demand for protein is rising due to increasing urbanization, rising incomes and the growth of the middle class. Seafood consumption is increasing, as seafood is a comparatively inexpensive source of protein. Learn how a new type of soy-based feed decreases the environmental impact of aquaculture, making it more sustainable.
