Hoggish Greedly introduces "dynamite-fishing" to the Philippines, since fishing by placing explosives in the water quickly kills fish...and is the perfect cover for him to dig in the coral reef their ocean ecosystem thrives on and steal and sell its remains. The Planeteers arrive to caution the locals to stop using explosives before the reef, and ultimately their way of life, is destroyed. They have trouble convincing Marcaria, a fisherman's wife, that any gains made will be overshadowed by the losses of sea-life and the length of time the reef would take to grow back, which Greedly's lies didn't mention. When they try to prove the damage to her while diving through the reef, Greedly captures Gi and the others are caught in an underwater cavern when coral struck from her torpedo against his blocks the opening. The other four must free themselves, since Captain Planet cannot stay thanks to Greedly's toxins, and release Gi and convince Macaria's husband Tacio and the other villagers ... Written by
