You're right Stu, and it's a very gloomy picture of financial gain at the expense of natural diversity of species.
Our Norfolk Wildlife Trust strives to educate and intervene wherever possible. Some farmers do, as you say, understand the precariousness of our wildlife. But most are in it for profit and nothing else.

However, when a livestock farmer finds his lambs massacred or his chickens slaughtered, his dairy cows failing their TB tests due (perhaps) to badgers transferring the disease, his crops gobbled up by crows and so on, he/she must feel beleaguered.

I have no answers to all that. But if some wildlife has to be controlled, let it be done humanely.
