eco-everything

i haven’t been in the US for three months, and one observation i have is it seems like the number of companies advertising their products in association with some kind of social or environmentally-conscious cause has exploded. mind you, it seemed like it was on the rise before, but my impression is that american marketers and advertisers are greenwashing practically any product, no matter how obviously inappropriate. how did people become so desensitized to doublespeak?
