With the 2024 Olympics Games underway in Paris, new environmental efforts are coming into play. Observers will sit on chairs made of plastic recycled from local bins. This decision was made due to a lack of unused raw materials to make new seats, so the eco-construction firm Le Pave turned to make the seats out of waste. Around 11,000 seats will be made from recycled materials.

The plastic collection for Paris 2024 has been carried out in the region's schools, and over five million coloured bottle caps have been recovered. Moreover, 80% of the 100 tons of recycled plastic needed to make the seats come from the yellow bins collections. This is all part of the Paris 2024 "zero waste" strategy to limit single-use plastic usage and encourage a circular (循环的) economy.

The Olympic Games organizers are planning to make the Paris 2024 Games the greenest Olympic Games yet. They intend to employ acarbon-neutral approach that will reduce the climate impact of the Games by avoiding, reducing and balancing emissions and encouraging others to get involved. The Summer Games have emitted 3.6 million tons of carbon emissions in previous years. The Paris 2024 Games has set a carbon budget of 1.5 million tons which includes the emissions from construction, transportation and operations of the Games.

These plans are ambitious but are achievable. If Paris 2024 successfully reduces emissions and promotes a circular economy, it might set the standard for future Olympic and Paralympic Games, regardless of where they are held.

The machine uses cameras and sensors (传感器) to sense its environment. It is able to recognize (辨认出) traffic lights which traditional guide dogs are unable to recognize. The robot can communicate by listening to and speaking with a blind person. The robot also uses artificial intelligence (AI) to recognize voices and plan ways to go from place to place.

The robot dog is about the size of an English bulldog but a little wider than a real dog. It has six legs instead of four because the researchers say the extra legsenhanceits safety, making its movements smoother.

41-year-old Li Fei and 42-year-old Zhu Sibin are among the people with eye problems who are helping the Jiao Tong University team. They are testing the dog using Chinese-language instructions and providing their feedback (反馈) for the researchers to further develop the dog.

Li is completely blind while Zhu has little eyesight. Li normally uses a walking stick to walk. He said, "If this robot guide dog comes onto the market and I could use it, at least it could solve some of my problems in traveling alone."

Robot guide dogs are also under development in Australia and Britain. But China needs a lot of traditional guide dogs. There are just over 400 guide dogs in China for nearly 20 million blind people.

Many workplaces, restaurants and public areas do not welcome a usual guide dog like a Labrador. The supply of real dogs is limited (限制) by feeding and training needs. The production of robot guide dogs could be increased to an industrial level, especially in a center of making industry like China. The researchers think there could be a large market for robot dogs as there might be tens of millions of people in the world who need guide dogs.

But surprisingly, with the loss of his legs, Leykin gained a new passion for racing. Before his accident, he wasn't really that athletic. He would just occasionally play basketball. But that all changed after he was introduced to hand cycling. "When I saw it, I was like, ‘Oh, this is great. You don't even need legs to use it. This is perfect.'" he said. "So, I got on it, I rode and fell in love with it right away."

Within a few months, he completed the TD Five Boro Bike Tour, a 40-mile ride through New York City. After that, he did his first marathon in 2021. He fished that race in 2 hours and 11 minutes, placing 12th out of 38.

"I'm going to attend this year's marathon and take on challenges. My hands are on the wheel, my eyes are focused, and I think my time is going to speak for itself." he said. He's made a significant commitment to training. He hand cycles at least 13.1 miles a couple times a week and spends a lot of time in the gym.

And he plans to keep pursuing his athlete goals. He wants to complete the Abbott Six-the world's six largest marathons. One day, he said, he'll maybe even make the Paralympics.

For those who might be following his journey, he hopes they will take some lessons from his story. "There will be ups and downs but the trend is what's important. Focus on the good," he said. "And also, take your big problems and split them into small solutions. And then all of a sudden, your big problems turn into many small wins."
