I imagine you are all familiar with the game of Jenga, in which a load of wooden "bricks" are stacked up into a tower.
Then players have to take it in turns to remove one brick at a time without the tower collapsing.
The other day (or rather night) I woke up in the wee small hours and switched on the radio: if there's something on that catches my interest, I am guaranteed to fall back to sleep before it finishes.
There was a programme on BBC World Service in which the presenter was being shown around London Zoo by one of the keepers. They talked about the tigers and gorillas I often show pictures of. The topic, though, was extinction of species. The keeper made an analogy that I found compelling.
Imagine, she said, a game of Jenga, but what we are removing are species of plants, insects, reptiles, mammals, fish. We don't know which will be the one that causes the rest to collapse - like the brick that collapses the Jenga tower - and we may suddenly find that our appalling stewardship of this magnificent planet has destroyed a vital ingredient and has finally led to its irreversible decline.
If humans are not causing climate change, but we behave as if we are, and clean up our act, the worst scenario is that we will have a cleaner planet.
If humans
are causing climate change, but we behave as if we are not, and do nothing, we will have destroyed the planet.
There is NO excuse for doing nothing.
