LettersThis Earth Hour, Hong Kong should resolve to switch to lasting change
Readers discuss the decisive collective effort needed to protect the environment, the culling of wild boars, and littering in country parks
WWF’s Earth Hour marks 20 years since its Sydney inception and 18 in Hong Kong. What began as a symbolic lights-off event has grown into one of the world’s largest environmental movements. As we prepare to switch off on March 28, the message must evolve from symbolism to urgent action. Our Earth doesn’t just need an hour of darkness; it needs a decisive, collective effort.
The science is dire: the goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels is slipping away, and the next five years are critical.
WWF-Hong Kong’s “State of Biodiversity report” warns that over 25 per cent of assessed species are at risk of local extinction – a crisis driven by climate change and biodiversity loss.
The Hong Kong government’s updated Biodiversity Strategy and Action Plan (BSAP) is a welcome step. It outlines four strategic areas and commits to encouraging nature-based solutions in major developments. However, a blueprint alone builds nothing. The difference lies in implementation over the next five years.
Earth Hour’s 2026 theme, “Give an Hour for Earth”, challenges us to move beyond the switch. It is a call to rethink habits, reconnect with nature and demand accountability. The symbolic act of dimming our skyline must translate into sustained commitment to the BSAP and the 1.5 degrees Celsius target. The next five years are our window of opportunity. Let’s ensure future anniversaries mark when we stopped just switching off lights and started switching on lasting change.
