The impact of these extra millions of people has spread even beyond the space they physically occupy. Their industries have changed the chemical constituency of the atmosphere. The oceans that cover most of the surface of the planet have been polluted and increasingly acidified. We now realise that the disasters that continue increasingly to afflict the natural world have one element that connects them all - the unprecedented increase in the number of human beings on the planet.

I don't see how you can be saying this. Look. You want to take...you want your god to take responsibility for the huge number of collapsing stars and imploding galaxies and destroyed universes and failed solar systems that have left us in this tiny corner on the one planet in this petty solar system that can support life some of the time on some of its surface. And you want a creator who filled this earth with species, since life began 99% of which are now extinct already...and this is some design, isn't it?
Christopher Hitchens
When we attempt to conceive the number of particles in an atmosphere, it is somewhat like attempting to conceive the number of stars in the universe; we are confounded with the thought. But if we limit the subject, by taking a given volume of any gas, we seem persuaded that, let the divisions be ever so minute, the number of particles must be finite; just as in a given space of the universe, the number of stars and planets cannot be infinite.
John Dalton
For generations, we have assumed that the efforts of mankind would leave the fundamental equilibrium of the world's systems and atmosphere stable. But it is possible that with all these enormous changes (population, agricultural, use of fossil fuels) concentrated into such a short period of time, we have unwittingly begun a massive experiment with the system of this planet itself...the increase in the greenhouse gases...has led some to fear that we are creating a global heat trap which could lead to climatic instability.
Margaret Thatcher
It stems from the loss of the election and the growth of the 'cowboys'. The Labour Party has got out of the way of losing elections. We are now the natural party of government... These cowboys are absolute Trots. The number of Communists in the party is very small but the Trots are much more sinister. They are negative and have no policy. There is a fairly high number of- not intellectuals but let's say intelligentsia element there, stemming not least from the growth of sociology as a discipline in the universities.
Harold Wilson
What right do we have to claim, as some might, that human beings are the only inhabitants of our planet blessed with an actual ability to be "aware"? ... The impression of a "conscious presence" is indeed very strong with me when I look at a dog or a cat or, especially, when an ape or monkey at the zoo looks at me. I do not ask that they are "self-aware" in any strong sense (though I would guess that an element of self-awareness can be present). All I ask is that they sometimes simply feel!
