I’m roaming the floor at the National FAA Foundation annual convention in Indianapolis today. I’ve had fun visiting with students and educators in agriculture. They love my school materials. Here I am, making the rounds. http://www.youtube.com/watch?v=Q83Wachb0yg
Turfgrass can boost your oxygen footprint.
Compared to bare ground, non-green areas, and lawn substitutes, such as painted concrete or even artificial turf, actual grass and green areas generate oxygen. For example, a turf area 50′ x 50′ produces enough oxygen to meet the everyday needs of a family of four and each acre of grass produces enough oxygen for 64 people a day.
