Freshwater uses and problems

UsesHow do we alter water/ Solutions:Steps to Water Conservation

In your groups… Brain storm a list of at least 5 uses for water (Be specific) Categorize your list into agriculture (*), industry(-) and household (___) uses.

Uses Agriculture: ** on your poster rate these from being most sustainable, 5 being less sustainable. 4. Furrow (65% efficent- oldest, easiest, cheapest) – 3. Flood: More disruptive but 80% efficent – 2. Spray irrigation: more expensive % – 1. Drip: over 95% efficent (reduces weed growth – 1. Hydroponic: uses 95% less water (water can be reused) more expensive.

Industry: generating electricity, cooling machinery, and refining metals and paper. ( use and return vs use and turn to steam) Housholds: toliets, bathing, laundry, cooking and drinking
