What does Scientology do to protect the environment?

In accord with a precept in the moral code they subscribe to, Churches of Scientology and their parishioners are very active in local environmental campaigns. Chief amongst their activities are: recycling projects, public park cleanups, graffiti removal, mural projects to beautify inner-city streets and highways, Earth Day educational campaigns and community clean-up campaigns. Scientologists in cities across Europe additionally dispose of hypodermic syringes discarded by drug addicts in parks. Care for the environment further extends to the use of environmentally friendly materials in the construction of new Scientology Churches.
