If you're in the UK, please take the time to sign this Not Dead Yet petition. It's asking MPs to take the time to sign up and say they support the Resistance Charter. By signing the charter they will be declaring that they will support palliative care and independent living services and also that they will maintain legal protection for disabled and terminally ill people.
There is also the option on the website to e-mail your MP about the issue - which I've done
Basically a lot of people are concerned about what might happen to the rights of disabled and terminally ill people - and the services a lot of people rely on if euthanasia was legalised. Personally I see it as potentially being a bit of a step backwards in terms of awareness, inclusion and disability rights.
