Talk is cheap, boasting, braggart. “But seeing this made me much more conscious about my plastic footprint and the need to reduce it — something everyone can attempt doing.”

Oxford Dictionary of Proverbs: Talk is cheap

Cf. [c 1600 A. Munday et al. Sir T. More (1911) 23] Woords are but wordes, and payes not what men owe; [1639 Chapman & Shirley Ball v. i.] You may heare talke; but give me the man That has measur'd 'em: talkes but talke.

Seying goes good cheap.
[1668 R. B. Adagia Scotica 47]

Talk is cheap, it don't cost nothin' but breath.
[1843 T. C. Haliburton Attaché I. ii.]

Talk's cheap. You could never make me believe that.
[1929 K. C. Strahan Footprints i.]

‘Talk is cheap‥because the supply always exceeds the demand.’
[2002 Washington Times 16 Mar. F15 (Herb & Jamaal comic strip)]

“The website enables many comparisons that, once seen, can no longer be unseen,” he said. For instance, humans outweigh wild animals 10 to 1, a fact that surprised Dr. Ménard. (“In my experience, most people expect the opposite.”) But we weigh only half as much as the livestock herds we maintain to eat. Perhaps more ominously, humans use 100 times their own mass in plastic.

“I knew the numbers,” Dr. Ménard said. “But seeing this made me much more conscious about my plastic footprint and the need to reduce it — something everyone can attempt doing.”
