Is Environmentalism a Religion?

An interesting outcome from a court case in the UK which I first mentioned a while back:

In a landmark ruling, Mr Justice Michael Burton said that "a belief in man-made climate change ... is capable, if genuinely held, of being a philosophical belief for the purpose of the 2003 Religion and Belief Regulations".

The ruling could open the door for employees to sue their companies for failing to account for their green lifestyles, such as providing recycling facilities or offering low-carbon travel.

I wonder if this will open the door to other "science-based beliefs" such as having to do with GMOs, illegal drugs and so on receiving legal protection. This will be discussed in depth I am sure.

UPDATE: The ruling strikes Ben Hale as "strange".
