Ecological Limits Quotes

Because the global ecosystem is a connected whole, in which nothing can be gained or lost and which is not subject to over-all improvement, anything extracted from it by human effort must be replaced. Payment of this price cannot be avoided; it can only be delayed. The present environmental crisis is a warning that we have delayed nearly too long.

It's coming home to roost over the next 50 years or so. It's not just climate change; it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.

Throughout all of human history we've enjoyed certain benign circumstances: an envelope of atmosphere, an envelope of temperature. A kind of resilience that if you cut down trees, then they'll grow back. You take fish, they recover. You put stuff into the atmosphere that you know is not good for us, but we can still breathe. We haven't awakened, generally, to the sense of urgency that does exist.

The greenhouse crisis is the bill coming due for the Industrial Revolution. It's not an accident. It's the logical outcome of our world view - the idea that we can control the forces of nature, that we can have short-term expedient gains without paying for them, that there are no limits to exploitation of the environment, that we can produce and consume faster than nature's ability to replenish.

The Government needs to recognise that we live on a planet with finite resources - and start measuring our progress as a society by the quality of our lives, not the expansion of our GDP.

As a global community, we have to start thinking more seriously about whether there are limits to what our earth can bear and if we're willing to cope with the struggle for limited resources, which only seem to increase as our population does.

Almost all systems of economic thought are premised on the idea of continued economic growth, which would be fine and dandy if we lived on an infinite planet, but there's this small, niggling, inconvenient fact that the planet is, in fact, finite, and that, unlike economic theory, it is governed by physical and biological reality

You can print money to bail out a bank, but you can't print life to bail out a planet.

What happens is all these things we're seeing – campylobacter, E coli, mad cow, listeria, salmonella, that weren't even in the lexicon 30 years ago – that is the industrial paradigm exceeding its efficiency. So these Latin squiggly words that we're learning to say – bovine spongiform encephalopathy – are nature's language screaming to us: ENOUGH! And the question then is: what will it take for us to listen? And my contention is that Wall Street is still wearing conquistador mentality and uniforms, and nobody is listening to the pleadings of nature saying: 'Enough.'

We don't even know what species are out there, for the most part, particularly when you get down to the microbes and very small invertebrates. They make up the mass of the organisms around us, including the soil we depend on, the soil of cornfields as well as hardwood forests. We haven't taken ecology to the point where we can even make a crude prediction of what's going to happen when we've reduced the living world down to a certain level.

Economic growth tends to require the taking of resources from the Earth. So something has to change on a debt-based economy.

Humans have occupied a position in nature that they should not. It is impossible for humans to conquer nature.

Capitalism can no more be 'persuaded' to limit growth than a human being can be 'persuaded' to stop breathing. Attempts to 'green' capitalism, to make it 'ecological', are doomed by the very nature of the system as a system of endless growth.

People always underestimate the ability of earth to increase its carrying capacity.

Despite our very recent appearance on the planet, humanity combines arrogance with increasing material demands, even as we become more numerous. Our toughness is a delusion. Have we the intelligence and discipline to vigilantly guard against our tendency to grow without limit?

Modern economic thinking...is peculiarly unable to consider the long term and to appreciate man's dependence on the natural world.

We're at peak oil, peak water, peak resources, and so either we figure it out and let science lead or we head down a very bad, dark trail to where a lot of people aren't going to make it.

You probably need 1/10 of the world's population for us to continue to exist. There's just too many damn people. You have to somehow get us from 7 billion people to... I don't know what the magic number is, but I imagine at some point, that will happen. And I don't know about you, but I don't think I'm making the cut.

Our economy is at war with many forms of life on earth, including human life. What the climate needs to avoid collapse is a contraction of humanity's use of resources; what our economic model demands to avoid collapse is unfettered expansion. Only one of these sets of rules can be changed, and it's not the laws of nature

In any race between human numbers and natural resources, time is against us.

I do believe this period of the 1980's will be remembered as the time the planet struck back. The planet is telling us we can't treat it this way anymore.

I don't believe in messing with mother-nature too much.

Our most serious problem, perhaps, is that we have become a nation of fantasists. We believe, apparently, in the infinite availability of finite resources.

We see an entire planet which has many limitations.

Wilderness is a resource which can shrink but not grow.
