4 . Usain Bolt burned about 10kcal of energy to win his gold during the 200 metre spring final at the Olympic Games, which could roughly power an old 60W light bulb for 11 minutes. If you could make use of all the power generated by all the athletes during the Games, you would still be nowhere close to reaching the 29.5 billion Watts consumed overall by the athletes, spectators and organizers over the event. We take sport for granted, but do we ever consider its cost to the planet?
From the water required to maintain the golf course during The Masters tournament to the hundreds of flights it takes to bring football fans to a World Cup, major sports events are not helping much in the fight against global heating. What’s more, there is a lack of recognition within sport of its responsibilities and little discussion about possible solutions.
This is strange, given that the effect works both ways: the climate crisis is not just affected by sports, but it is already having a negative impact on many sports. When ice-climber Will Gadd set out to conquer the world’s glaciers, he didn’t realize it would become a race against climate change. “I thought glaciers are there forever.” When he arrived at the summit, Gadd was shocked: “The ice…wasn’t there. The things I planned to climb were gone.”
Global heating is noticeable in other sports. Amy Steel played professional netball until she suffered from heatstroke after playing in 39℃ conditions and unfortunately, the damage was permanent. Not only that, but extreme weather events made more frequent as a result of global heating mean sporting events are more often delayed or canceled. This has cost sport billions in potential earnings.
Yet sport can be a powerful motivator: it can unite whole nations behind its teams. Could sport have a role to play in driving climate awareness? Will Gadd and Amy Steel are among many athletes who think so? One thing is certain. Sport must put climate change at the top of its agenda and decarbonize at a Usain Bolt-like pace to make a difference.

10 . When you are lying in bed, every single noise-from the creak(嘎吱声) of the bed to a whistle in your partner’s nose-may keep you awake. You may find it hard to get a good night’s sleep. Actually, you may just need more noise. While it may sound strange, it is scientifically proven that certain types of noise can help you sleep well. Specially white, pink and Brown noise can mask(掩饰) these sounds, creating a more harmonious background.
White noise contains sounds of all frequencies(频率) that humans can hear. But it comes across as a high-pitched buzz(声调高的嗡嗡声). That’s because of the way your ears hear it. Basically, your brain strengthens sounds in higher-pitched frequencies. So while you are hearing sounds from a variety of frequencies, the highest frequencies tend to drown(淹没) the lower-pitched ones.
The pink noise balanced out the noise so that sounds of all frequencies are heard equally. The higher the frequency, the more its volume is decreased. To your ears, the sound is deeper and softer than white noise. Think of rain falling on the sidewalk or a gentle wind in the trees.
In a study at China’s Peking University, researchers found that when people hear either pink noise or no noise during the sleep, 75 % reported more restful sleep with the pink noise. Brain activity monitors proved that people had 23 % more restful brain activity at night with pink noise and 45 % more restful sleep during naps.
Brown noise takes this concept to the next level, further weakening higher frequency noise to produce an even deeper and richer sound.
The color of noise that will help you get more sleep is the one you like the best. While pink and brown noises are deeper and more balanced than white noise, your personal sleep preferences will decide which one gives you the best sleep.
