On this week, we've learnt the basic concepts, concerning the environment, health and human being, include the definitions, determinants of health and the linkage behind. 
	When it comes to humans' constant interaction with the environment, environmental greening is a must to be mentioned. I'm fascinated by the concept of Vertical Forest. Vertical Forest is an anti-sprawl measure which aims to control and reduce urban expansion. It's a really nice idea of having home for trees that also houses humans and birds in a city. 
	After this lesson, I've searched more information related to the environmental greening. One of the well-known example outside Hong Kong is the Bosco Verticale. It is a pair of residential towers in the Porta Nuova district of Milan, Italy, between Via Gaetano de Castillia and Via Federico Confalonieri near Milano Porta Garibaldi railway station. I appreciate that most of the foreign countries place the Vertical Forest in the locations which are accessible to most of the citizens. Hence, it reminds me to think about the situation of greening inside Hong Kong. 💭 
	The GovHK(2020) has outlined the Hong Kong Government‘s greening policy, benefits of greening, Government's greening work, tree management and ways in which we can take part in greening Hong Kong. It clearly stated that our government is striving to uplift the quality of our living environment through active planting, proper maintenance and preservation of trees together with other vegetation. But is it really enough to just plant trees to green our city? 
	The article "Tree planting = greening? There are ways to add value to green cities" is thought provoking. It has stated the benefits of greening towards children's development. Three methods to maximize the environmental greening and highlight the value of greening the city, including having innovative design to add green elements, encouraging related industries to carry on greening jointly and improving the urban planning for green development, are also provided as well. As a pre-service kindergarten teacher, the mentioned resources are very practical and essential for my teaching in the future. 
	PS: I have a dream. A dream of having more green buildings in Hong Kong, especially in the urban area that are accessible for everyone!💚
