I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.
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.
You cannot look up at the night sky on the Planet Earth and not wonder what it's like to be up there amongst the stars. And I always look up at the moon and see it as the single most romantic place within the cosmos.
Of all celestial bodies within reach or view, as far as we can see, out to the edge, the most wonderful and marvellous and mysterious is turning out to be our own planet earth. There is nothing to match it anywhere, not yet anyway.
We can pay the ecological debt by changing economic models, and by giving up luxury consumption, setting aside selfishness and individualism, and thinking about the people and the planet Earth.
Hello from above our magnificent planet Earth.
The planet Earth, though not threatened with destruction by man-made global warming, is by no means indestructible. There are many unpredictable events within our solar system, and still more outside it, that could make Earth uninhabitable by humans.
What the fossil record does do is to force us to contemplate our place on the planet. We are but one species of several hominids that inhabited Planet Earth, and like our distant cousins who went extinct fairly recently, our time on Planet Earth is also finite.
Our meaning is to make our little planet Earth a better place to live, to stop wars, disarm nuclear missiles, to stop diseases, AIDS, plague, cancer and to stop pollution.
