After all, sustainability means running the global environment - Earth Inc. - like a corporation: with depreciation, amortization and maintenance accounts. In other words, keeping the asset whole, rather than undermining your natural capital.

Environmental activism against the resource industry is widespread all over the world, but at the same time we have to realise that these are basic materials on which civilisation depends. We need to tap natural resources in a sustainable manner.

Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.

Sustainability, ensuring the future of life on Earth, is an infinite game, the endless expression of generosity on behalf of all.

It angers me when sustainability gets used as a buzz word. For 90 percent of the world, sustainability is a matter of survival.

Humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel. This has resulted in a substantial and largely irreversible loss in the diversity of life on Earth.

When sustainability is viewed as being a matter of survival for your business, I believe you can create massive change.

When we realize that something as primal as the food that we choose to eat each day makes such an important difference in addressing both global warming and personal health, it empowers us and imbues these choices with meaning. If it's meaningful, then it's sustainable - and a meaningful life is a longer life.

The industrial processes in use today were developed at a time when no one had to consider what the environmental impact was. Who cared? But making ecological concerns matter to a company's bottom line will help it do the research and development that will reinvent everything we buy.

Sustainability makes good business sense, and we're all on the same team at the end of the day. That's the truth about the human condition.

Sustainability is not just about adopting the latest energy-efficient technologies or turning to renewable sources of power. Sustainability is the responsibility of every individual every day. It is about changing our behaviour and mindset to reduce power and water consumption, thereby helping to control emissions and pollution levels.

The care of the Earth is our most ancient and most worthy, and after all our most pleasing responsibility. To cherish what remains of it and to foster its renewal is our only hope.

Environmental concern is now firmly embedded in public life: in education, medicine and law; in journalism, literature and art.

Transparency, accountability and sustainability have become the slogans of the market leaders. Companies carry out environmental and social audits to court the consumer, and even the bluest chips woo organisations such as Greenpeace and Amnesty.

In a few decades, the relationship between the environment, resources and conflict may seem almost as obvious as the connection we see today between human rights, democracy and peace.

Environmental concerns and feminism are locked together. Generally, women have closer connections to the organic nature of our lives.

Beyond reducing individual use, one of our top priorities must be to move from fossil fuels to energy that has fewer detrimental effects on water supplies and fewer environmental impacts overall.

If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.

Our food is safer and our diets are more diverse than ever before; production methods are becoming increasingly sustainable, clean and efficient; and we are constantly becoming better at protecting biodiversity.

There's a rising tide of environmental awareness and activism among consumers that's going to continue to swell in the 21st century. Smart companies will get ahead of that wave and ride it to success and prosperity. Those that don't are headed for a wipeout.

There should be more attention paid to scientific research in the ecology area, and I think that such attention to proper environmental concerns would make the public feel much better about it.

As to the Amazon itself, the transition from conservation to sustainable development was a huge awakening since conservation was a western concept and strategy to encourage the developing world to protect biodiversity resources for the sake of future generations and the wellbeing of the planet.

We're saying environmental stewardship and jobs in the economy. We can do both together.

The education of women is the best way to save the environment.

Our challenge for the future is that we realize we are very much a part of the earth's ecosystem, and we must learn to respect and live according to the basic biological laws of nature.

In a few decades, the relationship between the environment, resources and conflict may seem almost as obvious as the connection we see today between human rights, democracy and peace.

Yet, despite our many advances, our environment is still threatened by a range of problems, including global climate change, energy dependence on unsustainable fossil fuels, and loss of biodiversity.

Environmental policy must strike a balance between the earth's best interests and our citizen's pressing needs.

What is now called 'green architecture' is an opportunistic caricature of a much deeper consideration of the issues related to sustainability that architecture has been engaged with for many years. It was one of the first professions that was deeply concerned with these issues and that had an intellectual response to them.

Nature is not simply a technical or economical resource, and human beings are not mere numbers. To suggest that one can somehow align all the squabbling institutions of science, environmental management, government and diplomacy in an alliance of convenience to regulate the global climate seems to me optimistic.

Global sustainability is now the only avenue to future inclusive progress that can deliver the Sustainable Development Goals and the Paris climate agreement.

Sustainability is the key to our survival on this planet and will also determine success on all levels.

Conserving energy and thus saving money, reducing consumption of unnecessary products and packaging and shifting to a clean-energy economy would likely hurt the bottom line of polluting industries, but would undoubtedly have positive effects for most of us.

Journey with me to a true commitment to our environment. Journey with me to the serenity of leaving to our children a planet in equilibrium.

Sustainability goes across everything I do with Adidas and everything I do with my own house, so the Olympic kit is no exception. It is incredibly environmental in the way that it is manufactured. For example, there's no leather; it's free from PVC. There's lots of woven materials, which means a lot less waste.

Momentum is building for the creation of a shared future, one that is more egalitarian, inclusive, and respectful of the environment - a future that ultimately offers greater possibilities for personal development and control over our individual lives.

A very Faustian choice is upon us: whether to accept our corrosive and risky behavior as the unavoidable price of population and economic growth, or to take stock of ourselves and search for a new environmental ethic.

Design, if it is to be ecologically responsible and socially responsive, must be revolutionary and radical.

A fascinating challenge facing today's environmental movement is how to best approach the reversal of past decisions that altered once-pristine environmental spaces for the sake of urgent man-made needs.

Moreover, the practical recommendations deduced from ecological principles threaten the vested interests of commerce; it is hardly surprising that the financial and political power created by these investments should be used sometimes to suppress environmental impact studies.

There is an old belief that solving environmental problems can only be achieved by first building enough economic wealth so we can 'afford to save the environment.' This 'Kuznets Curve' thinking has never been correct and must be abandoned once and for all if we are serious about economic development for a thriving humanity on Earth.

By uploading 40 years of 'Ecologist' editions online, we will be creating the world's most extensive ecological archive. 'The Ecologist' will continue to set the environmental and political agenda here and abroad.

Sustainability is no longer about doing less harm. It's about doing more good.

To cherish what remains of the Earth and to foster its renewal is our only legitimate hope of survival.

Somewhere down the line I'd like to create a foundation that brings awareness to environmental protection, sustainability, the effects of pollution, and all of those things related to protecting nature.

I hope my work contributes to understanding long-term patterns of human behavior and how we survive, thrive, or fail during times of environmental, social, and economic crisis.

I think the Greens are posing some of the most important questions of our time, for example how we live sustainably on a planet of finite resources and a rising population, and how do we do that in a way that doesn't exceed environmental limits and which is fair.

As an environmental scientist, I think our first need is to feed and shelter and nurture. That has always required the exploitation of plant life, and it always will.

Sustainable development is a fundamental break that's going to reshuffle the entire deck. There are companies today that are going to dominate in the future simply because they understand that.

Sustainable South Bronx advocates for environmental justice through sustainable environmental and economic development projects.

Addressing the climate and biodiversity crises requires us to radically change our economic models, moving away from economic growth as the over-riding measure of progress and moving instead towards improving health and wellbeing for people and nature. That means a different economic model taking us towards a sustainable economy.

The future of food security will depend on a combination of the ecological prudence of the past and the technological advances of today.

In particular, for younger researchers on whom the future of mankind may depend. We believe that they are working with all the scientific wisdom at their disposal for the preservation of the inheritance of the earth and for the lasting survival of mankind.

With increasing fervor since the 1980s, sustainability has been the watchword of scientists, environmental activists, and indeed all those concerned about the complex, fragile systems on the sphere we inhabit. It has shaped debates about business, design, and our lifestyles.

One of the most important lessons we can glean from the environmental movement is to 'think globally and act locally.'

Sustainability includes how you run your business, and my bottom line includes how you treat your people. Sustainability starts with your staff.

I'm into environmental and ecological issues, so maybe that is an avenue to go down.
