Cattlemen still do, depending on which beef you're referring to. Quite a bit of beef comes from Latin America, where rain forests have been replaced with grazing land whose products feed just one industry: Fast food. On the other hand, recently released studies indicate that the negative impact of cutting down forests, including tropical rain forests, have been greatly overestimated in the past. The total amount is insignificant in the grand scheme of things and, surprisingly, cutting down old trees allows new trees to grow that have much greater positive impacts on the atmosphere and environment. The overall effect is positive. Another case of over-zealous doomsayers? Eisboch Maybe, but new trees do not grow on grazing land. Otherwise, it would not be useful as grazing land. Agreed, but the amount that has been cut down is, according to the study, "insignificant" in terms of negative effects on the environment. Something like 90 percent of the forests remain, even after 40 something years of creating new grazing land. And the older, abandoned grazing land is supporting growth of new forests that convert more CO2 to O2 than old forests as they grow. Eisboch OK. |
