Millions of Americans enjoy playing golf, but golf courses are not known to be environmentally-friendly. They demand a lot of fresh water, fertilizers and herbicides to keep them looking green. That's true of most golf courses, but let's look at one that is trying something different. This is the Miami Beach Golf Club. The grass used here is called seashore paspalum.

It's the most environmentally-friendly grass in the world.

Doctor Ron Duncan is a turf researcher at the University of Georgia and a leading expert on seashore paspalum.

And environmentally friendly from the standpoint that you can save the potable water used for the human side and utilize 1 all other alternative water sources like brackish 2 water or water out of sewage plants to irrigate 3 this grass. Also you have a reduced management budget because it requires about half the fertilizers that you normally use on the other grasses. Also you can save on pesticide 4 use.

What makes seashore paspalum so special is that it can survive and thrive in high-salt environments. So brackish water or partially 5 salty water can be used to irrigate this grass. This translates into big savings 6 for the golf course.

We estimate at this point we are gonna reduce our dependence 7....
