In conjunction with Earth Hour 2015, World Wide Fund Singapore is holding an interactive exhibition along the pedestrian path outside ION Orchard and Wisma Atria. The trail showcases three possible scenarios as a result of global warming: a HDB flat facing an uncomfortable heat wave, a supermarket affected by food shortages and inflated prices and a shelter equipped to handle extreme weather caused by climatic changes. The trail is open 5pm-8pm on weekdays and 2pm-9pm on weekends.
