Dicamba Drift and the Monsanto Merger

March 15, 2018 -
A lesson in evolution: When farmers spray weed killer on their fields, there will always be a small number of weeds that survive. They have a natural resistance to the weed killer in their genetic makeup. Those are the weeds that go to seed that year, their children producing a crop of herbicide-resistant weeds the following year. By the next year, the farmer's fields are producing more and more herbicide-resistant weeds. What's a farmer to do? For those unwise enough to remain on the chemical treadmill, there's only one solution. Buy a stronger weed killer - to which a small number of weeds will, inevitably, be resistant.

This is precisely what happened to farmers that use Monsanto's weed-killer, RoundUp.  Monsanto's low-cost, highly ineffective solution to RoundUp-resistant weeds was to sell these farmers Dicamba, an old chemical weed killer with a tendency to drift. When pesticides travel on the wind, or drift, they damage crops and human health…

A Carbon-Free Grid

March 3, 2018 - Scientists at the University Of California, Irvine; the California Institute of Technology; and the Carnegie Institution of Science recently published an article stating that the United States could meet 80 percent of its electricity needs with solar and wind power. To sweeten the deal, the price of solar and wind have been dropping rapidly. The remaining 20 percent could be provided by alternate sources of energy such as hydropower, geothermal, and biomass. These sources currently meet 8.5 percent of electrical demand, and can be expanded. The remaining deficit would be met by managing demand.

The larger grid required for transmission of solar and wind power would have to be continental in scale, or 12 hours' worth of the energy would have to be stored in new facilities. This degree of expansion would require hundreds of billions of dollars in investment. Storing the electricity with today's cheapest batteries would cost a trillion dollars, although the price …
