Meat is fine.
Its putting food into gas tanks I am objecting to.
I'm curious as to how you make that distinction, as its an issue that I've been mulling over recently.
Take an area of arable land. Grow some
non-edible crop on it which can be turned into bio-fuel. Arguably, you're not putting food into gas tanks, so that should be fine.
Replace the non-edible crop with an edible crop, and its not fine? Why? You're using
the land to the same effect, so surely the base objection is that against arable land-usage which is not going towards feeding people.
Taking that reasoning a bit further...lets say I use my arable land to grow grain, which I then feed to my cattle. You say this is fine. But, I could stop feeding cattle, and use the same amount of land to grow enough grain to feed the same mouths as the cattle, and use the rest for bio-fuels. Now, although I'm feeding the same number of mouths, things are apparently not fine any more, because I'm using arable land for a purpose other than feeding people.
Strange, eh?
It would seem that
inefficient usage of arable land to produce calories is fine, but
efficient use is only acceptable as long as we don't convert from inefficient-to-efficient and put the reaminder to an alternate use!
Of course, someone will take this reasoning to its conclusion, and determine that I would appear to be suggesting that the only acceptable use of land is the most efficient production of food possible. Of course, I don't accept that for a second. Sure, it would allow today's population to be fed, which in turn would allow it to grow, until we reach the point where the population hits a ceiling in terms of the numbers we can feed...at which point it will grow some more and attrition will come back into play. With a greater base population, the numbers affected by attrition will be larger.
By such a line of reasoning, it would seem that the whole "arable land for efficient food production" is only leading us to a situation where
more people will ultimately suffer.
I would suggest that rather than arguing against the use of land for this purpose or that purpose, because it doesn't stave off the inevitable for a short period of time, we argue against the conditions that
lead to the inevitable regardless of how the land is being used.
