Yahiya and Sai Mohan are meeting after quite a while. They discuss, among other things, the plight of trash pickers, recycling of waste, land dump, Great Stink, fast world, human intervention, clean India, future generation, extinction. Depictions sandwiched between the dialogues shed light on the subject.
What happens when a (rationalist) professor meets his (religious) student outside the classroom?
Earth and Mars videoconference. Both planets are depicted as young men. Earth says, "I think my scrotal hair represents atrocities committed by United States during the Vietnam War." This signifies the U.S. military's massive aerial spraying of herbicides, called Agent Orange, tainted with a highly toxic dioxin, a long-lived chemical linked to many human health problems. Perhaps Earth tells Mars that it has become unliveable. Mars says, "I think my morning wood represents all the dreams I can't remember." Mars implies it is in seventh heaven, since no humans have ever been to Mars. The next image is of Mars with an erect penis in its upper part. This excites Earth which says, "I think we should make love without hurting your nature." Earth doesn't want humans to harm Mars, its newfound love. The next image is of both planets starting to have intercourse for the first time. Perhaps the erect penis will merge into the hairy scrotum, dance in the dark and they live happily ever after.
