Green Gurus launched the “Bring Butterflies Back” Signature Campaign on 13 Nov 2020 (Fri) on campus. With a rich flora and fauna, the current butterfly checklist in Hong Kong contains 245 species including one endemic subspecies, representing about 11% of species recorded throughout China. Besides being aesthetically pleasing, butterflies also play important roles in ecology, science and economy. However, butterfly populations are rapidly declining due to habitat loss, climate change and illegal collection. Through this campaign, Green Gurus hope to inspire CFSS students’ interest in butterflies and raise the awareness about butterfly conservation.
