Prince Charles said yesterday that he faces 'unbelievable abuse' every time he opens his mouth to speak his mind.

In a wide-ranging speech, he stressed on a greener economy, saying it was immoral to construct buildings without eaves for nesting birds.

He said we must consider other species who share this planet with us.

Prince Charles was speaking to delegates at the annual conference of the Prince's Foundation for the Built Environment at St James's Palace, London.

The Prince of Wales also said that he was accused of being the enemy of the Enlightenment. But, he added that he felt rather proud on being accused of being an enemy of Enlightenment, which was started 200 year ago.

Expressing his views, he said, “It might be time to think again and review it and question whether it is really effective in today's conditions, faced as we are with huge challenges all over the world.”

Prince Charles’ a number of views on agriculture and health have been described as ‘positively evil’ or ‘dangerous’.
