Even the respiratory protein haemoglobin, present within the blood cells, is at ﬁrst an embryonic haemoglobin optimally suited to aquatic gas exchange, to be replaced later by a different adult haemoglobin better suited to life on land and breathing with lungs and skin. Huge numbers of tadpoles are eaten by ﬁsh, newts, water-beetle larvae and dragonﬂy nymphs with which they share the water. When the time arrives for the amazing metamorphosis from tadpole to froglet, the tadpole grows legs, ﬁrst rear and then fore legs, and learns to swim with the webbed rear legs.

Much of the original forest was cleared to provide ﬁrewood and allow space for pastoral farming. It is therefore likely that forest species such as red squirrel, pine marten, crossbill and honey buzzard gradually found life less easy and much more conﬁned, and the plants and insects that thrived in forest understorey would also have declined. But it would not have been all bad news for wildlife.
This can be seen from space around the globe, especially in North America and Europe, and is often called the ‘green wave’. Hurricanes and tropical storms Although there are many predictions that the intensity and frequency of hurricanes and other tropical storms will increase in future as a result of global warming, it appears that claims that such an effect is already detectable are open to question. So I think it is premature to conclude that recent hurricane activity and strength, in themselves, provide evidence for world climate change through global warming.
