Naturalist Bill Oddie has said Britain's wildlife is suffering "one dip after another" and the Government is partly to blame.
The Goodies star, 72, blamed "very greedy humans" for destroying many species but added: "I think this Government is stunningly ignorant and arrogant.
He told the Radio Times:"The badger cull has had a lot of publicity but basically what you've got is scientific research that suggests this is not the way to curb bovine TB.
"But the Government turn round and say, 'Right, I see, we did this survey but it hasn't come up with what we want to hear so we'll ignore it'. And that seems to be the general attitude to just about everything."
Bill Oddie accused HSBC of funding the desecration of rainforests at the banking giant's annual general meeting.
HSBC's board members were confronted by the 71-year-old birdwatcher and broadcaster over its links to firms operating in Borneo.
Oddie, who used his position as a shareholder to raise the issue, said, "What's happening is that the logging companies have got the confidence and power and reputation because they have been funded by HSBC to expand and they are expanding across the world".
He added, "There's a huge desecration which at the root is funded by HSBC".
HSBC said it requires those banking with it to operate "legally and sustainably to protect the environment and local people" and has stopped providing services to 68 clients who failed to meet its standards.
Chief executive Stuart Gulliver urged Oddie to work with HSBC to tackle the issue, saying, "Give us the chance to be a force for good".
TV presenter and bird lover Bill Oddie has launched an online tirade against the Environment Secretary Owen Paterson.
Writing on his Twitter account, Mr Oddie voices a long list of grievances against the Secretary which include his alleged support of the badger cull, pesticides that harm bees and the hunting act.
Mr Paterson, who does not have a Twitter account, does not appear to have responded to the accusations so far.
Scientists have estimated that the number of nesting birds in Britain has plummeted by a fifth in the last fifty years - dying out at a rate of one pair every minute.
Figures compiled from volunteers' observations show that some 44 million birds have been lost from Britain since 1966.
