A team of 30 scientists across the globe have determined that the nine environmental processes named above must remain within specific limits, otherwise the "safe operating space" within which humankind can exist on Earth will be threatened. Amid some controversy, the group has set numeric limits for seven of the nine so far (chemical pollution and aerosol loading are still being pinned down). And the researchers have determined that the world has already crossed the boundary in three cases: biodiversity loss, the nitrogen cycle and climate change.
Jon Foley, director of the University of Minnesota's Institute on the Environment, and a leader of the group, lays out the limits and their implications for human action in an article in Scientific American's April issue.
He also discusses the issues in a podcast with our own Steve Mirsky.
Foley's team was so moved by the research effort that it put together a compelling video (see below) dramatizing the situation, generated entirely with typography, graphics and energizing music. You can learn more about the team's work at its research site, too.

It's sort of irrelevant. Humans will die out eventually, with or without change, and the planet will heal itself.

i do believe the earth has an equilibrium and if we change this it (being the earth) will write itself. This is not a convincing argument either way. It is not worth getting worked up about. There is no science here.

Belief has nothing to do with this. The only place science is absent is in your logic. It's not about the Earth you moron its about the human race (ie. survival); the Earth is a fucking rock.

It has to be us who decides to take responsibility for what we have done to strip her of life in order to preserve this planet for the future. If you want a planet that is liveable you have to work at it.

There is a video at this link that shows just one way we can revitalize soil and bring back carbon to it naturally in order to bring down carbon emissions and increase yields naturally. Industrial fossil fuel intensive agriculture is responsible for much of the degradation this planet currently suffers from, and that was brought on by us. It isn't going to go away by just waiting for it to happen on its own. Humans have trashed this planet and it is our responsibility to fix it.

Time is becoming the luxury we do not have enough of. People who stand in denial and obsfucation are the guiltiest of all. Those who see the truth and speak are derided as tree huggers, or alarmists. But the truth is we all will suffer the consequences of doing too little or nothing at all. To claim we shouldn't because the Chinese won't is the most warped logic of all. Our trade policies should back the commitment to fight global climate change with countries that do not endorse climate change legislation. Those who fail to act should lose most favored nation trading status with the United States. We as a country had better act fast as without our commitment no other country will feel the compelling reasons to work for reduction in greenhouse gases and fossil fuels as the choice to fuel our economies. Subsidies for big oil and coal must end, the prices must rise to impact the economy for without a rise in price of fossil fuels it becomes less attractive to invest in alternitive fuels and energy sources. End the susidies and impose a carbon tax that is steep in its price only then will we see the entrepenures emerge with the ideas to save the enviornment.

Just enjoy everything as much as you can before things get worse. Sadly this is the path we've taken and all the tech in the world isnt going to solve it. And human beings arent going to change.

Humans are indeed the main drivers of ENVIRONMENTAL change and the main exacerbaters of climate change. Who is poisoning the air and water? Cutting down the forests? Destroying the land with toxic organisms? Overfishing the oceans? Filling them with plastic swirling waste? Trashing it with wars? Sucking the lifeblood out of her? In the end then what we will have are people still spewing about how they are INNOCENT of anything on this planet and that they have no responsibility for it while they continue to spit on it. It seems human nature has hard wired many for ignorance and selfishness on this planet. And just as an aside: even if you don't think it is humans who are the main dirvers of environmental change because some invisible force is what is dumping toxic chemicals into our air, land, and water, and it is the polar bears cutting down all of the trees (yes, sarcasm), we are already at a tipping point on biodiversity and THAT alone should concern you.
But far be it for me to think this site would ever have a truly relevant discussion on that and solutions. Alll we ever get on Current anymore are the same trolls with the same BS responses.

I think it's naive to assume that an intricate collection of interacting systems has no point where it all falls apart. I try not to be pessimistic about the future of our planet but there is certainly an imbalance between what we need and what can be taken from the earth. The is little accountability on behalf of any organization or government. The key enemy of the earth is two words: plausible deniability. It's not right to say that it's an absolute fact that humans are the sole culprit of climate change but a little humility goes a long way. We have health insurance, auto insurance, home-owners insurance. Why? Just in case right? It's not unreasonable to scale up that comfort for the benifit of the entire world. If the facts weren't obscured by politics, we would perhaps achieve a greatness that is monumental. That is what I feel will mark the human race as a sucessful, respected, miracle of evolution.

I wonder if the sci-fi writers are on to something when people may have to live in domes or possibly in a lake or on the shelf of the Atlantic to survive the environment. The way global warming is going we are creating more moisture in the air causing more pronounced storms every year. Pretty soon the water will rise in the oceans, the ice will keep melting and the sun will not deflect off the ice caps. This isn't a cyclic type event either. We are tipping the scales. We are putting to much Carbon in the atmosphere. The ocean is releasing more, ugh. I just get depressed thinking about what we are doing to the earth. I think I will be safe while I am alive. I wonder how many generations it will take before something catastrophic takes place. There have been several movies produced that makes it look like it happens in a matter of weeks or months, that is a little over the top. But still it is sobering to think about.
I think Al Gore's Inconvenient Truth really opened my eyes to what is going on. I wish there were an update to the stats he produced in his slide show.

I also like numbers. It couldn't hurt. Some sort of countdown until our environment really turns on us. But hasn't it already. Why haven't the earthquakes hit in the U.S.A. Has the United States' ties to Christianity saved it from the wrath of the true god question mark
Still, why haven't electric cars become prominent with a power infrastructure built on renewable resources? How is it possible that the profitability of selling petrol is still dominating the earthly need to reduce carbon emissions?
ln a world where it is easy to make money on destruction, money becomes evil, but it controls us. Evil controls us. End the Fed. Default on all debts and tell the Rockechilds to go f themselves. and remember that gold is functionally worthless - 2 years ago

I'm going full dork...what you just described is the state of the planet in the Mass Effect series. According to the in-game codex, Earth is now beset by numerous storms due to the environmental damage we doled out.
Just thought I'd mention that.
Back to topic, the planet and it's living denizens are in serious danger. We need to take action and stop denying what's all around us.

Well, in retrospect it isn't as clean as say the Caribbean, Hawaii, or the Mediterranean. Kamino was akin to the Atlantic ocean. So I guess it could be cleaner. We pollute so much in our oceans that I am concerned about the heap of plastic that floats in the Pacific off the coast of California. It is huge and floats right under the surface for hundreds of miles. It is affecting our ecology at every level. We spill oil in the oceans and nuclear waste and chemicals that I cannot even pronounce. There are not enough regulatory authority. We need more to reign in these companies, not to prevent them from making a profit, but to hold them accountable for their illegal waste practices.
Ugh. I get sick thinking about it.

I think we are comparing planets, albeit that one of them only exist in our imagination, haha.
Global warming is occurring and it angers me that people deny it. People are completely ignoring the litter that is amassing in the Pacific ocean. There are so many chemicals being dumped into the environment. I think you and I are safe and have a chance of getting cancer. I think cancer will be something that is more prevalent as time goes on. Especially skin cancer from the sun as well as the chemicals we spill and pollute the the earth with.
It saddens me. As much as when Anakin was manipulated by Senator Palpatine (republican), hahaha.

We nerds fear natural light, so the skin cancer thing isn't a problem for me. I get my Vitamin D from Flintstones tablets. lol
Joking aside, the dumping in the oceans is just stupidity on humanity's part, let alone littering anywhere else. The Wal-Mart about five minutes up the street from me has garbage drifting about not only in the parking lot, but strewn all over the surrounding wooded area and for at least half a mile outward in any direction. My friends and I are going guerilla and bringing garbage bags and recycling bins and just cleaning up.
Can't ya just learn to look for a trash bin? Or better yet, just not shop at Wal-Mart?

Amen about not shopping at Walmart. Although, not an easy task. We are boycotting Walmart after seeing several documentaries about the corporation.
I just hope they will be held accountable for their abuse and also to allow unions to actually help the people that work for them.

That will be the day we achieve world peace, Cap'n. Regrettably, not likely to happen. Ugh. Sometimes humanity confuses me.
Don't get me wrong. I'm eternally optimistic about this sorta thing. But humans need a wake-up call, and it will likely have to be something drastic.

I don't think world peace is possible, unless there is one world government that can impose peace. Mention that though and people become unglued.
I see many problems spring from nationalism and different countries being rivals against one another. Religion doesn't help things either. Racial and cultural differences are like adding a match.
No easy answers, wars make money though so peace bears no profit.

I was in Rome last year and there was a huge peaceful protest, I almost ended up in the middle of a protest that if I would have had my photo taken I would have been in trouble, ahhaha. Fortunately, I talked to the police around the event and asked what it was about.
Can you imagine if tear gas would have broken out and they would have started beating people and arresting people. It is difficult to explain that away to the embassy staff, hahaha. Seriously, I was just walking through this large crowd and all of a sudden...hahaha.
