In 30 minutes of yapping about how joke-hova is going to heal the environment, one could have gone into a forest infested with Chinese wisteria vines and cut down enough of those vines to save perhaps 15 or 20 trees. Or one could fill a trash bag with plastic that otherwise would have ended up in the ocean. (And not wasting all the gas driving to the boasting session.)
In 30 minutes, someone could have gone to a supermarket and helped an elderly or house-bound friend or relative getting their groceries. One can help repair a bicycle (especially if said repair is a cable replacement, brake adjustment, a flat tire, or tightening loose bolts) for a friend. (Or your own, so you can take it out to the store for a short errand instead of the car.) You could also do some work on your own yard, if you own a house, to make it look more attractive.
And if the prayers are excessively long, add that to the amount of time you could be doing something constructive instead of wasting time asking that beady-eyed abomination to do anything.
