When considering the issues surrounding climate change one can easily become overwhelmed and conclude that the solutions are out of reach and beyond their control. However, communities in the UK and US can be found which empower local communities and restore faith in the future. Aside from international movements such as FridaysForFuture, more local groups can be sourced if you know where to look.
If you live somewhere in the UK, websites like Climate Action can be a great source of finding a local group near you. Or if you would like to join a more national body, The Conservation Volunteers is a great way to get involved.
If you live in the US, organisations such as Bioneers or OceansGlobal may be more for you. There are obviously a lot more groups out there, you may want to refer to the this list. However, being from an unreliable source you may want to take this list of recommendations with an eye of scrutiny.
Unfortunately, local climate change groups was not easy to find for other countries based in places such as Asia or Africa. However, from a broader more international standpoint this website article was a great source for examining climate change in different areas of the world and also providing the names of the international bodies focused on climate change in those areas.
