Clemson's onside kick went out of bounds. Coker took a knee and after a two-year drought that felt like eternity in Tuscaloosa, Alabama was back on top. The Crimson Tide became the second team in college football's poll era, dating back to 1936, to win four titles in seven seasons.
The Problem With Monocultures The problem with monocultures, Wetzel said, is that if an insect likes the crop, that insect has a large food supply to draw from all in one place. Conversely, a field containing a variety of plants does not offer a large block of food for the insect, so it will not get the nutrients it needs to survive and thrive.
Monocultures are not forests/ecosystems and do not stand long enough to lock-in carbon in the soil. Moreover, monocultures inhibit soil carbon up-take by frequent tilling and pesticide use. The no-till or low-till methods often advocated by biotech companies as crops deserving climate subsidies are not a solution either because of all of the problems associated with GM crops.
