Singapore observed the annual Earth Hour on 25th March 2017. Thousands of lights were turned off for an hour in a show of support for environmental awareness and protection. 

Yet, a billion people did not switch off their lights last night. Not because they were forgetful; they simply had no access to light. 

On a separate note, I have the privilege of attending Meet The Future, an exhibition organised by Shell in Singapore a fortnight ago. Many exciting and innovative ideas were showcased and I was most impressed with the idea of processing used coffee powder into energy-rich fuel pellets. 

Do you or your community adopt any practice(s) on a regular basis? If you do, would you like to care? 

If you are keen, you may want to share your thoughts on any environmental issue in your city.
