We are team GREEN from Shenzhen College of International Education. We realise that many vegetables and fruits in the Shenzhen market are imported from other provinces and countries. While transporting the products by planes or vehicles, there are many CO2 emissions. We build vertical urban gardens in the neighbourhood balconies to reduce carbon footprint and create a food source for the city. We also hold educational activities to promote the ideas of eliminating carbon emissions and maintaining city sustainability. We believe, through every single step of our action, we will achieve our final goal and make the city better.
