Moore warns that we are facing seemingly insurmountable problems: rising energy costs, escalating competition for arable land for agrofuels, the grow of invasive species, the herbicide / glyphosate - resistant superweeds effect, aquifer depletion, and end of cheap water as global warming melts glaciers, and the weakening effectiveness of fertilizers on yield growth.

The property firm Colliers International argued in a white paper this week that locating marijuana greenhouses on the least arable portions of B.C.'s Agricultural Land Reserve (ALR) would be «a viable alternative» to the province's dwindling supply of industrial land — particularly in the 148,000 - acre South Coast Panel Region that includes Metro Vancouver and the Fraser ValLand Reserve (ALR) would be «a viable alternative» to the province's dwindling supply of industrial land — particularly in the 148,000 - acre South Coast Panel Region that includes Metro Vancouver and the Fraser Valland — particularly in the 148,000 - acre South Coast Panel Region that includes Metro Vancouver and the Fraser Valley.

When the earth's temperature rises on average by more than two degrees, interactions between different consequences of global warming (reduction in the area of arable land, unexpected crop failures, extinction of diverse plant and animal species) combined with increasing populations mean that hundreds of millions of people may die from starvation or disease in future famines.

The natural variation that has led us out of the Little Ice Age has a bit of frosting on the cake by land use; and, part of that land use has resulted in a change in vegetation and soil CO2 loss so that we see a rise in CO2 and the CO2 continues to rise without a temperature accompaniment (piano player went to take a leak), as the land use has all but gobbled up most of the arable land North of 30N and we are starting to see low till farming and some soil conservation just beginning when the soil will again take up the CO2, and the GMO's will increase yields, then CO2 will start coming down on its own and we can go to bed listening to Ave Maria to address another global crisis to get the populous all scared begging governments to tell us much ado about... nothing.

You are unable to demonstrate based on empirical data that these temperatures will be harmful — and there are some indications that a slightly warmer temperature (especially in the higher latitudes, where GH warming is supposed to oiccur) will increase arable land surface across N. America, and Eurasia, lengthen growing seasons and result in higher overall crop yields.

One example is improving yield on lands already deforested to produce crops, thereby preventing additional deforestation driven by increasing demand for arable land.
