“Insect slime is only one of the problems facing the monument … The once mighty Yamuna — after being dammed upstream to provide electricity for the region surrounding India’s capital, New Delhi — now runs low and thick with trash and untreated waste, and blooms with insect-attracting algae. Auto emissions, deforestation and crop burning have contributed to heavy smog that experts say has dimmed the tomb’s pearly exterior to a jaundiced yellow.” Says one environmental activist, “The Taj Mahal has never looked as fatigued, pale and sick as it does now.”
