Aldo Leopold Quotes

Many of the earth's habitats, animals, plants, insects and even micro-organisms that we know to be rare may not be known at all by future generations. We have the capability and the responsibility to act; we must do so before it is too late.

That's what the best global conservation organisations and the American government (and other environmentally inclined governments, such as Sweden and the Netherlands) are doing: protecting the remaining wild environment. This is the equivalent of getting a patient to the emergency room - keep them alive and then figure out how to save them.

We should not knowingly allow any species or race to go extinct. And let us go beyond mere salvage to begin the restoration of natural environments, in order to enlarge wild populations and stanch the hemorrhaging of biological wealth. There can be no purpose more enspiriting than to begin the age of restoration, reweaving the wondrous diversity of life that still surrounds us.

The very fact that the jaguar can become extinct while the Pekingese survives indicates to me that someone hasn't thought this thing through.

If you can unify the public mind saving an iconic species like the tiger, like they did with the panda, that means you have to protect their habitat and everything that they hunt. And that means saving massive, thousands of acres for them to be able to roam and breed. So it's more of a land effort.

I believe in helping the planet survive, and that includes reaching out to help some of the disappearing creatures whose habitats we're destroying. It's up to us to somehow reverse that trend. I don't know how we'll achieve it, but we need to.

If my grandchildren were to look at me and say, 'You were aware species were disappearing and you did nothing, you said nothing', that I think is culpable. I don't know how much more they expect me to be doing, I'd better ask them.

For the most part we don’t have an immediate impact on the species that surrounds us. But we do have an immediate impact on their habitat which determines whether they survive on in some cases shift their ground.

The value of biodiversity is that it makes our ecosystems more resilient, which is a prerequisite for stable societies; its wanton destruction is akin to setting fire to our lifeboat.

So I think as a biologist I would like us to focus on this planet and finding solutions to sustaining humanity, to improving people's lives globally, but doing our absolute utmost to preserve as much biodiversity as we can, knowing that we have already been responsible for the loss of thousands of species.

We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.

Biodiversity is the totality of all inherited variation in the life forms of Earth, of which we are one species. We study and save it to our great benefit. We ignore and degrade it to our great peril.

What other species now require of us is our attention. Otherwise, we are entering a narrative of disappearing intelligences.

What they [Jim deMint and the oil lobby] do care about is the precedent. If they open up ANWR (Arctic National Wildlife Refuge), they'll think they can do anything to the environment - anything at all. Drilling in Yosemite? In the Grand Canyon? What's next?

We have a responsibility toward the other life-forms of our planet whose continued existence is threatened by the thoughtless behavior of our own human species. . . . Environmental responsibility – for if there is no God, then, obviously, it is up to us to put things right.

Looking around the world at these wildlife, it's abundantly clear that humans have benefited from nature in so many ways but have also brought many species to the brink of extinction...The American people that I interact with through my IS Foundation work do not want to allow this to happen; they do not want to let these species go without a fight; and they see the way in which nature provides for people around the world.

Humans are a great survivor species but our survival will be pretty grim if all of the plants and animals we depend on die out. That's why any human survival strategy has to include a plan to maintain our environment roughly in the state that it's in now.

We must be certain that the repair to the environment is sufficient to allow wild species to recover and survive.

We human beings are not only the beneficiaries but also the stewards of other creatures. Thanks to our bodies, God has joined us so closely to the world around us that we can feel the desertification of the soil almost as a physical ailment, and the extinction of a species as a painful disfigurement. Let us not leave in our wake a swatch of destruction and death which will affect our own lives and those of future generations.

Even if we act immediately, the world is doomed to lose many of its animal and plant species and this inturn will reduce the ability of ecosystems to deliver vital services to human populations. The Red List gives all of us a practical tool for raising awareness of the biodiversity crisis and for forging new partnerships within the international community.

The preservation of biodiversity is not just a job for governments. International and non-governmental organisations, the private sector and each and every individual have a role to play in changing entrenched outlooks and ending destructive patterns of behaviour

When I was very young, biology, the diversity of life, was one of my main interests. I know there's this image people have that I'm this spoiled, cocky punk of an actor. Honestly, that's not who I am. I really care that so many species have been wiped out, like genocide of entire races. I believe in the divine right of all species to survive on this planet. So I decided I want to be active as an environmentalist. I learned. I asked experts. I got active.

Having studied biology really helped me a lot because I quickly understand how biological systems work, and how they fail, and the tragedy of when they fail, because we are dealing with life systems, and when we hear that a species has become extinct, or is threatened, you realize that this could mean that this species will disappear from the face of the earth forever! So that understanding really gives you energy to do something to save it.

On an overcrowded planet where more species slip toward extinction every day, should one species have the right to multiply and consume at will, even as it nudges others to oblivion?

Dr. S. Dillon Ripley, secretary of the Smithsonian Institute, believes that in 25 years, somewhere between 75 and 80 percent of all the species of living animals will be extinct.
