Neil deGrasse Tyson Quotes

We actually have 10 times as many cells of microbes on us as we have human cells... We are literally a teeming ecosystem of microorganisms.

You live in intimate association with bacteria, and you couldn't survive without them.

Am I simply a vehicle for numerous bacteria that inhabit my microbiome? Or are they hosting me?

Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.

You think of yourselves as human beings, but I think of you as 99 percent bacterial.

We inherit every one of our genes, but we leave the womb without a single microbe. As we pass through our mother's birth canal, we begin to attract entire colonies of bacteria. By the time a child can crawl, he has been blanketed by an enormous, unseen cloud of microorganisms - a hundred trillion or more.

We are inhabited by as many as ten thousand bacterial species; these cells outnumber those which we consider our own by ten to one, and weigh, all told, about three pounds - the same as our brain.

One bit of advice someone gave me - which I haven't yet tried - is that if you go to an area where you might pick up a tummy bug, you should seek out the local probiotic yogurt. Eating it will introduce you to the local gut flora, apparently.

If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)… Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.

We should not be living in human communities that enclose tiny preserved ecosystems within them. Human communities should be maintained in small population enclaves within linked wilderness ecosystems. No human community should be larger than 20,000 people and separated from other communities by wilderness areas. Communication systems can link the communities.

The living environment is the biosphere, the thin layer around the world of living organisms. We're part of that. Our existence is dependent on it in ways that people haven't even begun to appreciate. Our existence depends not just on its existence, but its stability and its richness.

We have to create a sustainable environment, worldwide, and we're not doing it. The best thing we can do with the rest of this century is aggressively acquire - and put aside - the richest natural reserves that we can, and then do our best to manage the needs and desires of the 11 billion people we expect to have by the end of the century. This is where biology is headed. For that reason, the sooner we get on with mapping biodiversity on Earth, the better off biology will be - not to mention the whole subject of saving it before we carelessly throw it away.

Some of us believe humanity should be in divine partnership with nature, some people believe that man has been given by God the right to have dominion over nature. But since even they say that we should be good stewards, that right there should be the common ground.

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.

It is the abiding concern of thinking people to preserve what keeps men human-to save our contact with nature of which we are a part.

In other words, people should be placed in parks within ecosystems instead of parks placed in human communities. We need vast areas of the planet where humans do not live at all and where other species are free to evolve without human interference. We need to radically and intelligently reduce human populations to fewer than one billion.

Certain people always say we should go back to nature.I notice they never say we should go forward to nature. It seemstometheyare more concerned that we should go back, than about nature.

People today have forgotten they're really just a part of nature. Yet, they destroy the nature on which our lives depend. They always think they can make something better... They don't know it, but they're losing nature. They don't see that they're going to perish. The most important things for human beings are clean air and clean water.

There are more microbes per person than the entire population of the world. Imagine that. Per person. This means that if the time scale is diminished in proportion to that of space it would be quite possible for the whole story of Greece and Rome to be played out between farts.

To exist as a nation, to prosper as a state, and to live as a people, we must have trees.

Many people feel small because they're small and the universe is big, but I feel big.

I'm willing to engage or indulge real ideas, but if we don't do something [about global warming], we're all going to die! What's it going to take, a big f--ing disaster with all kinds of people dying? We need to change our priorities fast.

While I am a great believer in the free enterprise system and all that it entails, I am an even stronger believer in the right of our people to live in a clean and pollution-free environment.

Eat a plant-based diet - which act like prebiotic and probiotics in the gut.
