In shows, such as Big Brother where humans are seen literally parading about and behaving in a manner really befitting a human zoo enclosure (a lot of the time), we could have a Big Brother for animals entitled The Big Critter, where the animals compete to outdo each other - eg the giraffes compete to see who gets the most attention from the zoo-keepers (who's prepared to stick their necks out furthest) and the male tigers compete as to who has the cleanest teeth. The male birds would also get to flaunt their amazing plumages for the benefit of the females, of course. The animals and birds could compare notes about their skills ... who is fastest/flies the furthest, and the trees could even compete as to who gives out the most oxygen, and takes in the most CO2S, the plants that perform the best in terms of bio-filtration. This would be a fun animated quiz show.
Perhaps, tone it down, Nicolle, you are getting too carried away, again with your ideas for environmental media. There is bound to have been a satire done of Big Brother in this way! And a far more intelligible discussion of green humour occurs here.
