I have just been moved, angered, saddened and inspired by the BBC's Natural World on Hawaii - Message in the Waves.
The programme itself was easy to follow, had a very strong message and reminded us about the importance of, not only understanding issues ourselves, but also passing on this ownership to children too.
We all know how hard it can be to convince young people to do things, and try things, that they don't think is cool, that their friends don't do and that they would normally give no thought to. But we need to keep going and teach, engage and inspire them at every opportunity, celebrate every little success and never give up on anyone. Only by doing this can we hope to make a difference and, even if that difference is only part of our own small back yard then we have done our 'job'. Lots of small back yards make many vast plains.
