As far as food and agricultural crops are concerned with variables thus far imposed, most growth responses to elevated levels of atmospheric CO2 are favourable. They include increases in total dry weight, root growth, higher root/top ratios, leaf area, weight per unit area, leaf thickness, stem height, branching and seed, and fruit number and weight. Organ size may also increase along with root/top ratios…Important for agriculture is that there is an increase in the harvest index and the marketable product, and a shortening of the growing season with earlier maturity resulting in reductions in both water and pesticide requirement.
There has been, and still remains, a great reluctance on the part of many climatologists and ecologists, and especially environmentalists, to accept the concept that the rising level of CO2 could be more beneficial than harmful for plant growth, food production, and the overall biosphere (Rozema et al, 1993). Yet the scientific evidence is overwhelming.
One of the remaining mysteries of modern science and technology, and presumably an educated and enlightened generation, is that in the majority of studies of global food security (FAO, 1981, 1984, 1986; Meadows et al., 1972; Crosson and Anderson, 1992) there is a failure to factor in any climate variables, even though climate is the most determinative factor in agricultural productivity (Oram, 1989
Furthermore, seldom, if ever, in textbooks and other documentaries on agricultural food production, are the fertilizing effects of atmospheric CO2 acknowledged. This was true over 30 years ago (Norman, 1962). Now, after more than a century [of controlled experiments, and the evidence of the benefits over the whole twentieth century], and with the confirmation of thousands of scientific reports, CO2 gives the most remarkable response of all nutrients in plant bulk, is usually in short supply [note well!], and is nearly always limiting for photosynthesis [i.e. its shortage rather than other factors usually sets the limits on the rate of photosynthesis]. Moreover, in some of the latest reports and projections on world food production and security, the rising levels of atmospheric CO2 as a contributing plant growth factor do not receive mention (Crosson and Anderson, 1992; Edwards et al., 1990; Per Pinstrup-Andersen, 1994; World Food Council, 1992.)

Religion is the root of any culture, and environmentalism has become a full-fledged religion in its own right. It is the most comprehensive substitute in the world today for Christianity so far as world view, theology, ethics, politics, economics, and science are concerned, and you need to understand it in order to counter it effectively, from presuppositions to policies, from classroom to movie theater, from evening network news to Internet and local newspaper.
And because environmentalism—the word coming from French meaning “surroundings,” that is, “everything,” and so meaning literally “everythingism”—because environmentalism is inherently totalitarian, demanding to define and control every aspect of life, it aims to take control of our entire political and legal structure, and indeed has already advanced far in that direction over the last three decades. You, as an individual, have a tremendously important role to play in the church’s battle against this impostor, with its alternative world view, its substitute doctrines of God, creation, man, sin, and salvation, and its lethal mix of bogus science and Marxist economics that threaten to fulfill the radical environmentalists’ and deep ecologists’ dream of ending industrial society and forcing humanity back into a primitive lifestyle—in which, as Thomas Hobbes put it, life was solitary, poor, nasty, brutish, and short.
