So our wildlife is ever more caught between not just the devil and the deep blue sea, but many another threat to its continued survival. 3 CLIMATE CHANGE As was emphasised in Chapter 2, climate change is by no means new to Planet Earth. However, what seems special about the present scenario is that increasingly evidence indicates that we humans are playing a major role in its inception and persistence.

As agriculture became more mechanised and intensive, the requirements for hedges and field margin strips disappeared, as did most of the common weeds of farm crops. Farm animals would spend more time indoors and less time providing the once-widespread crop rotations of alternate grass and grain or potato crops. Also, just as Rachel Carson so accurately predicted, the reliance of advanced agriculture on synthetic insecticides and herbicides would put paid to previous insect abundances, and also lead to the rapid decline of species such as kestrels and sparrowhawks, whose position at the top of the food chain led to their accumulating lethal concentrations of organochlorides in their tissues and eggs.
