Which came first, the moth or the cactus?
... populations increase, more flowers are destroyed, fewer new cacti appear, and the spiral continues until both species disappear. Yet that hasn't happened, and Holland, assistant professor of ecology and evolutionary biology, spends several months each year observing moths and cacti in the Mexican desert...Conventional plowing is 'skinning our agricultural fields'

No-till farming can build soil fertility even with intensive farming methods, he said, and it could prove to be a major benefit in a warming climate.

There were fewer RIF due to gamma rays than the model predicted, and they appeared more gradually.
