The production of natural resources in agriculture, forestry and fisheries, stable natural hydrological cycles, fertile soils, a balanced climate and numerous other vital ecosystem services can only be permanently secured through the protection and sustainable use of biological diversity.
To emotionally accept impending disaster, to attain the gut-level understanding that the power elite will not respond rationally to the devastation of the ecosystem, is as difficult to accept as our own mortality. The most daunting existential struggle of our time is to ingest this awful truth-intellect ually and emotionally-and continue to resist the forces that are destroying us.
We need to start looking at having a way of managing the whole ecosystem, because you can't pick away at it piece by piece, you have to truly start being coordinated and managing our resources as a system. We haven't gotten to that point yet.
Basically, I think 21st century conservation is moving toward preserving ecosystems by dealing with the needs of people.
Now is not the time to repudiate environmental balance, but rather it is the time for all of us to work together - politician, advocate, rancher, scientist, and citizen. Only by doing this will the United States move forward and be a leader in environmental issues and ensure sustainability to our delicate ecosystem.
The agriculture we seek will act like an ecosystem, feature material recycling and run on the contemporary sunlight of our star.
I would remind people on the planet that this is the only one we have, and we need to take care of it. I would want people to truly consider what we do and how we treat the earth, the ecosystems, and animals we share it with, and think about the legacy we want to leave behind.
The First Amendment has the same role in my life as a citizen and a writer as the sun has in our ecosystem.
To achieve true sustainability, we must reduce our "garbage index" - that which we permanently throw away into the environment that will not be naturally recycled for reuse - to near zero. Productive activities must be organized as closed systems. Minerals and other nonbiodegradable resources, once taken from the ground, must become a part of society's permanent capital stock and be recycled in perpetuity. Organic materials may be disposed into the natural ecosystems, but only in ways that assure that they are absorbed back into the natural production system.
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.
For me the protection of Planet Earth, the survival of all species and the sustainability of our ecosystems is more than a mission. It is my religion and my dharma.
The most important thing we can do to save our oceans is to dramatically expand our efforts to establish new marine protected areas and make sure that critical fish spawning sites and ecosystems remain undisturbed.
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.
We don't know nearly enough about the complexities of Nature. If we think we can eliminate natural ecosystems and substitute prosthetic devices, i. e. clean air or water with fusion energy - we are kidding ourselves.
All of a sudden, if you think about the entire ecosystem of connected devices that can pull down information, access content and allow me to share and work and communicate, the vast majority now are not Windows computers. They are iPhones. They are iPads. They are Android devices.
We are all together in this, we are all together in this single living ecosystem called planet earth. As we learn how we fit into the greater scheme of things, and begin to understand how the system works, we can plan ahead, we can use the resources responsibly, to show some respect for this inheritance that goes back 4. 6 billion years.
The great ecosystems are like complex tapestries - a million complicated threads, interwoven, make up the whole picture. Nature can cope with small rents in the fabric; it can even, after a time, cope with major disasters like floods, fires, and earthquakes. What nature cannot cope with is the steady undermining of its fabric by the activities of man.
The raising of animals for food and all that it entails is the single most destructive force impacting our planet's fragile ecosystems. Our planet simply cannot sustain the greed of billions of human beings who are eating other animals.
You can't start with imbalance and end with peace, be that in your own body, in an ecosystem or between a government and its people. What we need to strive for is not perfection, but balance.
If you want a cow to be not just a cow but a milk machine, you can do a very good job at that by creating new hormones like the Bovine Growth Hormone. It might make the cow very ill, it might turn it into a drug addict, and it might even create consumer scares about the health and safety aspects of the milk. But we've gotten so used to manipulating objects and organisms and ecosystems for a single objective that we ignore the costs involved. I call this the "monoculture of the mind. "
