Humans are remarkable: the first species in almost four billion years of life on earth that dominates the biosphere. This gives us the power, in principle, to build societies in which everyone flourishes. But it also creates great dangers because it is not clear that we really understand how to use our potentially devastating powers.

American Historian

Robert Zubrin

By enriching the carbon-dioxide content of the atmosphere from its impoverished pre-industrial levels, human beings have increased the productivity of the entire biosphere - so much so that roughly one out of every seven living things on the planet owes its existence to the marvelous improvement in nature that humans have effected.

American Scientist

David Grinspoon

Certainly for me, as an astrobiologist, science fiction has played an important role. One of the quandaries of our field is that we are trying to study and search for something - life - that we can't define in a rigorous way. We only have one example of a biosphere, so we can't really give a good definition.

Meat consumption is a part of our evolutionary heritage; meat production has been a major component of modern food systems. Carnivory should remain, within limits, an important component of a civilization that finally must learn how to maintain the integrity of its only biosphere.

Czechoslovakian Scientist

Gregory Benford

Very little useful science got done in the space station. NASA never did the experiments needed to develop the technologies required for a genuine interplanetary expedition: centrifugal gravity to avoid bodily harm and a truly closed biosphere.

American Physicist

David Suzuki

This is suicidal... our home is the biosphere. That's a very thin layer of air, water and land where all life exists. It's fixed, it can't grow, and yet we cling to this idea that the economy can grow forever. And it must. Well, it can't.

Canadian Scientist

Tristram Stuart

It feels like an easy sum to gauge the balance between forests and, say, the proliferating free newspapers that litter our public transport. This noxious combination of words and paper represents a clear-cut crime against the biosphere.

English Author

Greta Thunburg

I mean, people aren't continuing like this and not doing anything because they are evil, or because they don't want to. We aren't destroying the biosphere because we are selfish. We are doing it simply because we are unaware.

Swedish Environmentalist

E. O. Wilson

It's always been a dream of mine, of exploring the living world, of classifying all the species and finding out what makes up the biosphere.

Jacques Monod

Chance alone is at the source of all novelty, all creation in the biosphere.

French Scientist

The biosphere includes all ecosystems, from the deepest ocean to the highest mountain where life exists.

Living Layers

'Biosphere' refers broadly to life on Earth, emphasizing the interconnection of air, land, and sea life.

Broad Concept

When 'biosphere' is used, it often involves discussions of environmental science and ecology.

 we had to ask ourselves some pretty basic questions. I mean, what is a biosphere? Back then, yes, I guess we all know now that it is essentially the sphere of life around the Earth, right? Well, you have to get a little more specific than that if you're going to build one. And so we decided that what it really is is that it is entirely materially closed --

 That's why we call it a biosphere - bio, meaning life and sphere, meaning circle. And there you go! When you break it down to each level, a very complex concept and phrase becomes easy to understand. All life starts with a single cell. When cells join together,
