David Attenborough quotes - page 6
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.
David Attenborough
We keep putting on programmes about famine in Ethiopia; that's what's happening. Too many people there. They can't support themselves - and it's not an inhuman thing to say. It's the case. Until humanity manages to sort itself out and get a coordinated view about the planet it's going to get worse and worse.
David Attenborough
Very few species have survived unchanged. There's one called lingula, which is a little shellfish, a little brachiopod about the size of my fingernail, that has survived for 500 million years, but it's survived by being unobtrusive and doing nothing, and you can't accuse human beings of that.
