Has anyone been an activist regarding environmental issues?

I used to have a blog in 2007/2008 about renewables and environmental issues, got about 50 unique visiters per day on average.

My aunt is also the co-founder of the Oxfordshire green construction network https://www.renewableenergyhub.co.uk/Forum/general/uk-to-lose-0-5gw-of-capacity-in-the-new-year/ and is a frequent speaker on BBC Radio Oxford about environmental issues.

I've never been politically/environmentally active in this sense, but I have every intention of raising awareness in the future. I'm pretty new on the scene, so I'm still learning quite a lot as I go. I like to know everything there is to know before I go preaching a gospel to climate change naysayers. For example, I still don't fully understand Micro CHP or biomass boilers, but I'm getting there

I would never class myself as an activist as such, but at the same time I do certainly try my best to spread the word about issues whenever I can. I would actually like to have more to do with campaigning, but unfortunately I'm so busy at work that it just isn't something that I am able to do at the moment really.
