The inventor of the Gaia theory
Transcript of an online chat, Friday September 29, 2000
One of the (if not the) main initiator of the modern Green movement, James Lovelock discusses with some internet correspondents, his friendship with William Golding who named the Gaia theory, the end of our civilisation, and the benefits of nuclear power for the environment.
starling:
Are you prepared to accept an ethical dimension to your Gaia theory
whereby all lives have equal value? Or are we, as humans, entitled to
favour ourselves as we must in everyday life?
James Lovelock:
So far as Gaia is concerned, humans are not special. We're just
another species. There is a strong ethic attached to Gaia, and that
is that the species that lives well with its environment favours it
for its progeny and the species that fouls the environment spoils it
for its progeny and goes extinct.
nsalt:
Your thoughts on nuclear power are refreshing. For so long it has
been singled out as the evil amongst energy sources while
conventional power stations the world over continue to belch their
polluting gases. But there is a risk factor with nuclear power even
if it's smaller than that of coal etc. Renewable fuels, particularly
biomass, used locally on a small scale seem better still. Should we
be putting more effort into this research?
James Lovelock:
Large-scale nuclear power is the only practical way that we have
to solve the greenhouse gas problem. Of course we should do
everything else as well including renewable fuels, windmills, but we
should recognise that these are no substitute.
greenday:
You probably get asked this a lot, but how did you come to know
William Golding, who gave Gaia her/its name? What was he like and
what did he think of the theory?
James Lovelock:
I knew Bill Golding as a neighbour when I lived in Wiltshire. He was
a good friend and we would often talk as we walked to the village
post office about half a mile away. When it was something exciting,
like Gaia, we would walk well beyond the post office. He liked the
theory, perhaps because he had been trained in physics as a student
as well as in the arts. He said that if you would put forward a big
theory about the earth, you'd better give it a good name and he would
call it Gaia. We walked on for 20 minutes talking at cross-purposes
because I thought he meant 'gyre' (I have no classics). Then Bill
said no, I meant Gaia - the Greek goddess.
jjjeremy:
You say that nuclear power plants may be useful in supply electricity
without worsening global warming. But doesn't it take generating
extra greenhouse gases to be able to build and then dispose of one
nuclear power plant. A nuclear power station also has to be very big
to work with a centralised power grid and we would need to build a
lot of them across Europe. Wouldn't we just end up with big,
inefficient plants and lots more greenhouse gases? Wouldn't it be
better to decentralise the grid, build efficiency into useage and the
grid, use renewables and take away the subsidies from nuclear power
generation and give this to alternatives?
James Lovelock:
It's true that building a nuclear power plant will require a lot of
concrete and release a lot of carbon dioxide into the atmosphere.
However, a plant runs for 50 years or more, and in that time release
vastly less greenhouse gas than fossil fuel-burning power stations. I
believe that in Sweden small-scale nuclear power stations have now
been designed for public use.
kudra:
What are your thoughts on the recent fuel 'crisis' and the way that
it was/is being handled?
James Lovelock:
The public response to the recent fuel crisis appalled me. They
seemed to have no idea whatsoever of the dangers that lie ahead and
thought only of their immediate personal needs. I should not have
been surprised because in China, with its truly powerful government,
they have admitted that they cannot hold back the personal
aspirations of the people where burning fossil fuels is concerned. In
a survey during the Suez fuel crisis, people interviewed claimed to
be prepared to pay so much for fuel that their families would be in
danger of privation. They valued personal mobility above all else.
This is a human characteristic. I think the Chancellor is right -
you've got to be tough on this one.
nisaac:
I think that Gaia is a great metaphor for processes in the biosphere.
However, I've been disappointed to find that other ecologists
instinctively recoil at the idea of the Planet Personified. Whilst
they are right to argue in favour of rigorous hypothesis testing, we
all need some kind of bigger picture. What do you make of this? Where
is the halfway house?
James Lovelock:
I think the biologists fight dirty. You have to use metaphor to
explain science to people. The biologists have the wonderful metaphor
of the selfish gene. No one challenges them, saying 'how absurd - how
could a gene take thought and be selfish?' So why do they dislike my
metaphor of a living earth? It's very expensive to experiment with
the earth - as we shall soon find out, for that's exactly what we've
been doing with C02s.
rgsharp:
How would you sum up the concept of 'Gaia'?
James Lovelock:
Gaia is a theory about the earth. It sees it as a self-regulating
system. It keeps its climate and its chemistry always comfortable for
whatever is the contemporary biosphere. Its major difference from
older evolutionary theories such as Darwinism is that it sees
organisms not just adapting to the environment, but changing it as
well.
rabbit:
How far do you consider the name 'Gaia' to be responsible for the
popular attraction to your theory? Equally, how far do you consider
the name to be responsible for popular misunderstanding of the
theory?
James Lovelock:
Folk need a good metaphor and 'Gaia' has helped establish herself
by her nice short name. Naturally, many academic scientists do not
like this way of presenting science.
buttercup:
If you were prime minister for a day, what would be the one law you
would pass to try to restore our relationship with Gaia?
James Lovelock:
A few years ago, I published an article in Science,the American
equivalent of Nature. In it, I considered what might happen in the
21st century. Perhaps we would go on slowly getting a little more
crowded and a little more polluted, but still civilisation would be
much as before. Alternatively, we could suffer any one of several
catastrophes, such as a volcanic eruption no more severe than
Tamboura in 1815 or Laki in Iceland in 1783. These two volcanoes put
so much dust into the air that the sun's rays were enfeebled, the
earth grew cool and there were two years without harvest. There were
then far fewer people in the world, so there were famines, but not
enough to destroy civilisation. Just imagine what would happen now.
It is said that we have no more than 15-50 days' grain stocks in
store at any one time. Two years makes this seem a very short time.
So what can we do about it? One thing we can do is to make sure that
our successors in the next Dark Age know what we did wrong and have
encapsulated in a simple book all the hard-won key facts of science,
philosophy, art, etc that would enable them to start the new
civilisation. I would like to see the book as a primer for
primary-school use to make children familiar with what our
civilisation really was. It would be as well-written as the Tyndale
bible and kept in every home - thus available, should disaster
strike, for our successors.
blackbird:
The greenhouse effect and the potential damage to the ozone layer has
only entered the public consciousness in the last 10 years. With the
onset of unleaded petrol and 'environmentally friendly' products, is
it really a case of too little too late?
James Lovelock:
Too little too late? It may be too late to save civilisation, but
people will survive and there will be another one. There were 30
before the present, so why should this one be so special?
blackbird:
And what are your views on GM Crops, how do they fit into the gaia
theory?
James Lovelock:
My feeling about GM crops is that we are straining at a gnat
while swallowing the camel of greenhouse-gas accumulation.
That's all I have time for - thanks very much and goodbye.
