That is the idea my friend @lemouth, both my husband @amestyj and I, in the scenarios in which we share knowledge with producers or students, we try to show our vision about the field, it is a controversial issue, as it affects largely the economic factor, however we can improve production models in search of the survival of our species on the planet.
It is a pleasure to exchange ideas through this medium, happy day!
