What's been changed by campaigning?

Over the last few months some have suggested that charities in the UK shouldn’t be involved in campaigning and influencing.
Charities have a proud role in mobilising public pressure for a good society and a safe planet.
Charities have successfully campaigned to protect public health from smoking; to protect the UK’s finest wildlife; to maintain liberties and freedoms; to achieving greater equality for women, and for lesbian and gay people; to enabling the UK to show global leadership on issues such as climate change or tackling disease, and so much more.
Many charities have a long histories of campaigning for change, but while the stories and examples of successful change brought about campaigning are passed down within organisations they aren’t collated together in one place.
Changed by Campaigning aims to change that. 
Working with campaigning colleagues from across the environment and development sector I’m trying to collect together in one places a list of issues that have been Changed by Campaigning over the last 100 years.
Can you help by adding any examples from your organisation or work of issues that have been Changed by Campaigning here?
It shouldn’t take more than 10 minutes to complete the form – and we’ll use the examples to help make the case for why charities should continue to have the freedom and space to campaign.
We’re aiming to get a first list of what’s been Change by Campaigning in the UK together by early June, and I’ll try to make the material available to those who read the blog.
