Ben Zand travels to the northern coast of Borneo, where reefs once famed for their biodiversity are being blown apart by fishermen using homemade explosives to stun and kill fish in bulk. He talks to the bombers themselves about why the practice persists despite wrecking the coral their communities depend on, and to those watching the fish stocks and their traditional way of life collapse in real time. The second report moves to Karachi, Pakistan's wealthiest city, where thousands of families face chronic water shortages driven by climate change, official mismanagement, and criminal control of the supply. The crew follows residents who spend up to half their salary buying water illegally from tanker gangs, and others who stay up through the night waiting to see whether a community tap will be switched on for even a few hours. Together the two reports show environmental and infrastructure crises playing out at street level, told through the people losing the most.
