I see a world in the future in which we understand that all life is related to us and we treat that life with great humility and respect.

And that, quite simply, is the issue. We live in a finite world with finite resources. Although it may sometimes seem quite big, earth is really very small - a tiny blue and green oasis of life in a cold universe.

Humans are now the most numerous mammal on the planet. There are more humans than rats or mice. Humans have a huge ecological footprint, magnified by their technology.

With an estimated population of nine billion people by 2050, we cannot continue to consume resources at the same rate and maintain our quality of life.

But human borders mean nothing to air, water, windblown soil or seeds or migrating fish, birds or mammals.

The failure of world leaders to act on the critical issue of global warming is often blamed on economic considerations.

The event of creation did not take place so many eons ago, astronomically or biologically speaking. Creation is taking place every moment of our lives.
