Middle Class Climate Activism?

The report from the head of Natural England claiming that the creation of new national parks in England will help us counter climate change seems, to me, unduly optimistic (https://www.theguardian.com/environment/2019/jul/31/englands-new-nature-reserves-will-help-us-tackle-global-heating). It may make a minor improvement (perhaps reduced somewhat by more folk driving their 4x4s to visit the locations) but I really think that the scale of required action is considerably greater than that.
