One of my hobbies is golf – a wonderful game. (Not quite tennis, but better suited for my age.) However, a golf course can be very environmentally unfriendly: chemicals particularly but also energy consumption,, etc. The FFG (France Federations de Golf) has a broad program on making golf courses as environmentally benign as possible, reducing use of chemicals and operating in a much more sustainable fashion. The program is linked here: https://www.ffgolf.org/Transition-ecologique. So I have joined a club that participates in this program – one benefit, and is also geographically much closer – a reduction in car/Uber miles. Perhaps the second benefit will be greater than the first, but we will have to see. In any case, I encourage my golfing friends and colleagues to consider this theme.
