Sir, – Artificial snow has been used in the Winter Olympics but only to top up the natural snow to ensure the optimal conditions for the games. Unfortunately, the Winter Olympics next month will be conducted almost entirely on man-made snow, which is not sustainable ecologically.
Similarly, hosting the Fifa World Cup in Qatar is predicted to produce up to 3.6 million tonnes of CO2.
A space-age stadium is built with an unprecedented energy-hungry cooling technology that is too expensive and notoriously unsustainable for the environment.
Although the sporting events are important for healthy socio-economic development, it is equally important to focus on environmentally friendly and cost-effective games for a sustainable future. – Yours, etc,
