01. The problem with exotic tree species

Although exotic species can grow rapidly, they don’t offer an ideal food source or habitat for native wildlife, such as birds and insects. Plus, exotic trees even suppress the growth of surrounding native trees.


To improve Hong Kong’s long-term biodiversity level, we must take action for our country parks.


In addition, every plant has a life span. So you can imagine problems such as aging and tree falling as exotic trees grew over the years. These problems have emerged lately due to the recent super typhoons.



The health of people is interconnected and interdependent with the health of trees and the wider eco-system. We need to look after one another, whilst taking care of the environment.

From today till 31 July, The Green Earth, together with Bupa and our Bupa4Life members* will 'plant' a virtual One Health woodland for Hong Kong through a step challenge.

We aims to promote the concept of 'One Health' – the relationship between the health of humans and nature.

Let's learn more about Hong Kong's woodlands and their biodiversity, and discover the positive impacts through walking!

Let's work out for more steps!
Build a local woodland in four - stages.

Transform your steps into (virtual) trees and rewards.
