Stop unsolicited mail being sent to people's homes and businesses

I want the government to ban the sending of unsolicited mail to peoples homes and businesses in the UK. Unsolicited items are causing avoidable environmental damage by adding to the mountains of recycling. I feel they are an intrusive and a waste of paper. People should have to 'opt in' and register to receive unsolicited mail as opposed to having to 'opt out' as the process is now. I think removing unsolicited items in the mail will reduce waste and help protect vulnerable people from being scammed.
