Attitude change starts with awareness and can grow with time even if it seems to do so slowly.
As for some scepticism about organisations environmental or not, fair enough, but it seems odd to spend "many many years" researching in depth into their backgounds. Guess the French secret service did that when they blew up Greenpeace's Rainbow Warrior, in the name of national security. Still a job is a job. Nudge nudge wink wink say no more.
