Grasses like this may be part of a solution, where it will be need to be part of a new approach to agriculture, which will involve a combination of measures, that will allow us to be more compatible with the environment.
Things like putting back into the soil what is taken out, with fewer chemicals like pesticides, and herbicides, which nature cannot digest, being left behind.
If we try and compete with nature, we lose, we need to learn to work with nature, and the resources it has available - how nature and mankind should be on the same team, but we spend too much time banging our heads against the immovable object that is nature.
We often seem to be trying to replace what is natural with our own ideas, but the time that we can run a show as well as nature, is a long way off.
It's about time we tried to learn.
