Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.
I have always preferred to liken the championship to a marathon. You have to know how to start the race, how to take the strain when problems come along and to make sure you don't give any potentially dangerous rivals an advantage. My policy is to ideally have five or six men around the age of 26, a couple of youngsters, a couple round the 28 mark and one or two in their 30s. But the nucleus of the team should be experienced and not too old.
