In Oz farming is on the nose and considered by some environmental groups as the industry that should be eliminated ASAP because of its impact. Environmental costs of farming are no more costed than those of any other industry. If mineral fuel sources are replaced by renewable combustion then the only environmental saving is in the release of CO2. The arguments against global warming are mostly social or humanitarian since the rate of warming is likely within the parameters of natural change. Given the apparent attitude of some environmentalists to humanitarian issues this spells hypocrisy.
