A few weeks ago I went to a monthly free environmental movie showing at a near by theatre and saw a movie called “Dirt” http://dirtthemovie.org/. It was really interesting to learn how dirt is made and how thin a layer of dirt on this Earth is useful for crops. In the movie it showed some machines harvesting trees and other vegetation, some of the machines were HUGE! It makes me wonder can we develop machines on the same scale to manufacture soil. Can we do it with natural energies? We really need to put food security as a number one priority for all people. We cant do anything until we do that. I’m a big advocate for lower global population even for Canada but we can’t do this until we have food security.
Check out “Dirt”
definition of food security according to wikipedia “Food security refers to the availability of food and one’s access to it. A household is considered food-secure when its occupants do not live in hunger or fear of starvation.”
