It is becoming
increasingly common for people to take up a vegetarian or even a vegan diet.
The numbers are muddled. Far more claim to be vegetarians than actually are. Roughly
5% claim while maybe 1-2% really are. The discrepancy seems to arise with
people adopting a generally vegetarian diet but occasionally eating meat. This
is sometimes called a flexitarian diet.
I must say I
prefer the American usage of describing vegetarian food as plant based. This is
clear when choosing and avoids the tinge of “weirdness” particularly around
vegans.
The evidence
that plant based diets prolong life appears somewhat thin. Some studies show an
effect, some don’t. It does appear that red meat particularly in quantity has a
life shortening effect. Some categories such as smoked meats appear definitely
harmful. On the other hand oily fish are positively recommended. One clear
peripheral benefit is reduction in obesity. While this is not an integral part
of plant based diets they certainly help. It
isn’t as simple to take in the excess calories which is all too easy
with a normal diet.
It would appear
that the main motivation for veggies is aesthetic or moral. Certainly if you
stop and think eating the dead flesh of animals isn’t very nice and also
objection can be made that meat production is cruel. There is some movement
towards more humane animal treatment such as legislation on chicken cages.
The main
objective reason for supporting the vegetarian movement is the health of the
planet. This has in two aspects; the production of greenhouse gases and energy
efficiency. Firstly the main red meat is beef and cows produce a lot of methane
in their digestion. This methane is belched or farted into the atmosphere and
is a major contributor to the greenhouse effect behind global warming. Grazing
takes up a large area ( some suitable as arable land ). This links to energy
efficiency. A cow is a very inefficient way of producing protein; vegetable
crops produce far more per unit energy applied.
It is
increasingly clear that climate change is here. Far from being a future problem
it is certainly having effects here and
now. The main effect is that extremes of climate are getting worse with some organisms
are struggling to adapt. The toll of extreme weather on human life and
prosperity is increasing. The adaption problem is perhaps best exemplified by
coral where increases in temperature can kill. It is estimated that all coral
will die before the end of the century.
I have slowly
come to understand the visceral rejection of climate change by some because it
is seen by them as some kind of “liberal” plot to change their way of life. I
see that even terminally stupid Trump is now starting to acknowledge that
climate change is real. However many deniers , including Trump, see climate
change as uncomfortable and inconvenient. Far too many see it as depressing the
economy. This is quite untrue as it is quite possible to have economic growth
and adjustments to emissions. This simply means doing things in different ways.
I wonder if
many of the objections to things like wind turbines which have puzzled me are
simply those who object to any change which may affect their routine or the
ways they have grown accustomed to. To be quite personal I have had a solid
fuel fire for over 30 years but I am coming to the realisation that is probably
not very healthy and although I burn some wood it is not good to the
environment. In principle growing wood takes up carbon dioxide from the
atmosphere which is released back when burnt so is carbon neutral. The
practical problem is that an open fire releases small particles of carbon which
are unhealthy if breathed into the lungs. It is also very inefficient as much
of the energy goes “up the chimney”.
This digresses
somewhat from the main point that climate action and economic growth are by no
means incompatible. Far too many “green” supporters also take a hair shirt
approach and seem to relish throwing away much of modern living. It is a fact
that the energy needed per unit of economic growth has been steadily falling.
In summary it
appears that vegetarianism is marginally good for the individual and definitely
good for the planet. However it may well be that the sizzling steak may have be
largely replaced by an equally attractive vegetarian option.
