I think environmentalism is a dynamic thing, and is influenced by many different factors. I googled environmentalism to see the definition and these are some things that came up: the activity of protecting the environment from pollution or destruction; the philosophical doctrine that environment is more important than heredity in determining intellectual growth. From these definitions it seems clear to be that environmentalism is based on beliefs or morals. However, I don’t think these beliefs or morals necessarily have to be related to religion or a specific religion. Christians, Jews, Muslims, paganisms, atheists, etc can be environmentalists. I think these basic ethical views are a major part of environmentalism. But science most definitely has a part in environmentalism too. There is a ton of scientific evidence relating to the environment and humans affect on it. This scientific evidence alerts environmentalists and clashes with their beliefs. Basic facts don’t have an affect on a person unless they have an opinion or beliefs to analyze these facts. I guess it can become complicated when opinions differ or class, but I think these core values of protecting the environment lie at the core of environmentalism. Science can provide solid evidence to go with these beliefs.
