Event Details

During the pandemic, Plastic Trasher went on a rampage, leaving behind rubbish all over the countryside. To restore the environment to its original state, Eco-Rangers have repeatedly gone to country parks and beaches to engage in hill and beach cleaning. They not only remove litter from mountains, fields, and coastlines but also recycle recyclables left behind by humans, allowing the recyclables to enter the realm of a circular economy.


As COVID-19 subsided, the littering problem of the countryside remained unresolved while the threat of global warming crept ever closer. The greenhouse effect has led to rising temperatures on Earth; nowhere is safe from the attack of heatwaves. The Hong Kong Observatory has also added the “Extremely Hot” weather warning, evidence that the issue is right at our doorstep.


Extreme weather has brought disasters to all parts of the world, including severe wildfires in Canada, Hawaii, Greece, Australia and more. Prolonged high temperatures have evaporated water from the Earth’s surface and vegetation, causing forests to become dry and highly flammable. This creates the perfect conditions for wildfires, where even a tiny spark can trigger a massive blaze, engulfing entire woodlands. Large trees provide shade for humans and play a crucial role in mitigating climate change by absorbing carbon dioxide from the atmosphere. The bigger and older the trees are, the more carbon can be stored. If forests around the globe shrink significantly, there will be far fewer trees to take up carbon; at the same time, carbon stock in trees will be released into the atmosphere, increasing the carbon dioxide and worsening the impact of global warming.


Our countryside is no stranger to man-made hill fires. In the face of such challenges, Eco-Rangers must gather at once to defend the environment!

How to Play



Flame Thrower moves swiftly and fiercely, ready to set the whole forest ablaze with the tiniest ember. To repair the burnt forest and prevent further damage, Eco-Rangers (participants) must use a compass and the map provided to finish tree conservation missions in the designated area within 2 hours. Let’s join forces to protect our environment!



Scoring Method:


Family Team (include tree conservation missions)

Eco Rangers will carry out tree conservation missions in the designated area. Eco Rangers who can act quickly and accurately to complete missions will earn the title of "The Strongest"!


Other categories

Points will be awarded according to the number of conservation traces (check points) visited as an orienteering competition.


The team which earns the highest score within the given time limit wins. Teams that exceed the given time limit will have their score deducted accordingly. Should there be a tie with more than one team having the same score, the team with the shorter time wins.
