We have much to learn by studying nature and taking the time to tease out its secrets.

Nature surrounds us, from parks and backyards to streets and alleyways. Next time you go out for a walk, tread gently and remember that we are both inhabitants and stewards of nature in our neighbourhoods.

The question is whether we're going to start taking the steps now to avoid the really big jumps that are in store if we don't do something now.

Scientists are being portrayed by much of the power structure in politics and business as having a vested interest - that they're just out to get more grant money by exaggerating the threats.

As parents, grandparents, uncles and aunts we need to start getting out into nature with the young people in our lives. Families play a key role in getting kids outside.

We emerged out of nature, and when we die, we return to nature. We need to know there are forces impinging on us that we will never understand or control. We need to have sacred places where we go with respect, not just looking for resources or opportunity.
