If you wanted to convince people that human reproduction is killing the earth, you would convince them that their worship of phallic gods was actually just worship of the sun's rays, festivals, wine, or any other seemingly non-threatening characteristics. This is also why so many cultures worshipped animals like bulls, goats, and lions, since they all are known for their fecundity. And this is probably why King Tut was found with his penis embalmed in an erect position, yet you only hear about the gold. It represented Osiris' reproductive energy, and that's why you often see murals depicting Osiris with an erect penis. I wrote a lengthy paper about this in college, so I have tons of examples.
