Some people think that our planet is suffering from a fever. Now scientists are telling us that Mars is experiencing its own planetary warming: Martian warming. This has led some people, not necessarily scientists, to wonder if Mars and Jupiter, non signatories to the Kyoto Treaty, are actually inhabited by alien SUV-driving industrialists.
There are still so many places on our planet that remain unexplored. I'd love to one day peel back the mystery and understand them.
I theorize that there is a spectrum of consciousness available to human beings. At one end is material consciousness. At the other end is what we call 'field' consciousness, where a person is at one with the universe, perceiving the universe. Just by looking at our planet on the way back, I saw or felt a field consciousness state.
We owe it to each other - and to our children and grandchildren - to leave our planet in a better state than when we found it.
Hundreds of millions of human beings on our planet increasingly suffer from unemployment, poverty, hunger, and the destruction of their families.
With about a dozen assorted ongoing conflicts in the news every day, and with the stories becoming more horrific, the level of sadness becomes unbearable. And what becomes of our planet when that sadness becomes apathy? Because we feel helpless. And we turn our heads and turn the page.
Growing hemp as nature designed it is vital to our urgent need to reduce greenhouse gases and ensure the survival of our planet.
Wilderness is harder and harder to find these days on this beautiful planet, and we're abusing our planet to the point of almost no return.
The strongest signals leaking off our planet are radar transmissions, not television or radio. The most powerful radars, such as the one mounted on the Arecibo telescope (used to study the ionosphere and map asteroids) could be detected with a similarly sized antenna at a distance of nearly 1,000 light-years.
We need happy, productive citizens on our planet for us to survive.
Energy is one topic on which different countries can work together collaboratively. If we can all produce energy from an element that's available in abundance on our planet, that would be a good thing, but we have to learn how to produce energy in large quantities, cheaply, efficiently and without detriment to the environment.
Saving our planet, lifting people out of poverty, advancing economic growth... these are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women's empowerment. Solutions to one problem must be solutions for all.
I am joining the hundreds of thousands who shall be marching in the Virtual March on Washington to Stop Global Warming in order to demonstrate the concern that we all hold for the future of our planet and all the living things - flora, fauna, human and animal - that exist upon it.
As the great grandchildren of the industrial revolution, we have learned, at last, that the heedless pursuit of more is unsustainable and, ultimately, unfulfilling. Our planet, our security, our sense of equanimity and our very souls demand something better, something different.
I grew up loving X-Men, Spider-Man and Batman. Those are obviously the key big ones, but there's always something kind of cool about Aquaman still, the idea of creating a huge world that is on our planet.
All the conservation efforts in the world won't be enough to make a dent in the oncoming sustainability crisis our planet faces.
Evolution isn't just a story about where we came from. It's an epic at the center of life itself. Far from robbing our lives of meaning, it instills an appreciation for the beautiful, enduring, and ultimately triumphant fabric of life that covers our planet. Understanding that doesn't demean human life - it enhances it.
The ability to collect, analyze, triangulate and visualize vast amounts of data in real time is something the human race has never had before. This new set of tools, often referred by the lofty term 'Big Data,' has begun to emerge as a new approach to addressing some of the biggest challenges facing our planet.
If we take into account the existence of our planet, we have to recognise that we are guests that spend a short and very determined period in this world, and all we leave behind is nuclear waste.
Maybe it's because I look into the future professionally, but I see great possibilities for both humanity and our planet. I don't believe the thriving of one has to come at the expense of the other, and I'm deeply concerned to find out whether other people do think that.
It has only been within my lifetime that asteroids have been considered a credible threat to our planet. And since then, there's been a focused effort underway to discover and catalog these objects. I am lucky enough to be part of this effort. I'm part of a team of scientists that use NASA's NEOWISE telescope.
If a gigantic asteroid were barreling toward impact with our planet, you can bet there would be at least a few members of Congress who would insist on leaving it alone, either because they would see it as a warning shot from the Almighty or because a mining company with a savvy team of lobbyists had laid claim to the big rock.
I'd love to be an astronaut. I bet you get a better understanding of our planet seeing it from a distance.
Health and well-being, as well as how we can live in harmony with our planet, is something I'm passionate about.
I am aware of the sufferings of women in India, which is also the suffering of women in many, many countries on our planet. My heart is filled with empathy and love for them.
What's happening to our world? Imagine the year 2000 and our ozone layer has vanished... Our planet has a fever and she is burning up - what will you do?
Life is fragile: it thrives only in a narrow range of temperatures between freezing and boiling. How lucky that our planet is just the right distance from the sun: a little farther, and the death of the perpetual Antarctic winter - or worse - would prevail; a little closer, and the surface would truly fry anything that touched it.
Imagine what our planet would look like with an increase in temperature of two degrees or four degrees, given that at 0.8 degrees we already have serious problems in the world.
'Plan Nine From Outer Space' for a new generation, 'Battlefield Earth' is set in the year 3000, after the beings from the planet Psychlo have conquered our planet in only nine minutes.
If we each take responsibility in shifting our own behavior, we can trigger the type of change that is necessary to achieve sustainability for our race or this planet. We change our planet, our environment, our humanity every day, every year, every decade, and every millennia.
I think having toured the world and seeing many places, I've just been blown away by how we've really scarred our home. I'm as guilty as the next person if not more so. I travel a lot. The damage we do to our planet is huge.
We must preserve our planet and grow our economy simultaneously. We cannot become more prosperous without the living systems upon which our prosperity depends.
I believe that climate change represents one of the greatest threats to our national security and our planet.
Protecting our Great Lakes and conserving this resource for the next generation is critical both for surrounding communities and our planet as a whole.
What is our destiny? Does it matter? Is it bound up with 'our' planet? In my opinion, yes.
Shelters, conservationists, those concerned about unnecessary cruelty toward the animals we eat, and people working against species extinction fight to preserve the true riches of our planet, our real inheritance. These are big, critical goals.
