Hey there! 😊 Have you ever thought about how clean the air is in big cities? Well, here’s some great news from Beijing, the capital city of China! In 2024, Beijing had 290 days of good air quality—the most since they started keeping track! That’s a lot of blue skies! 🌤️
That means that in 2024, almost 80% of the days had clean air, which is 19 more days than the year before and a whopping 114 more days than back in 2013! Isn’t that amazing?
You might be wondering, what about the days when the air wasn’t so good? Well, the number of days with heavy air pollution went down a lot—from 58 days in 2013 to just 2 days in 2024! That’s a huge improvement! 🚀
But how do they know the air is cleaner? They measure something called PM2.5. These are tiny particles in the air that are so small, you can’t see them. They’re smaller than a speck of dust! 🌬️ In 2024, the average amount of PM2.5 in the air was 30.5 micrograms per cubic meter, meeting the national standards for four years in a row!
Not only PM2.5, but other pollutants like PM10, nitrogen dioxide, and sulfur dioxide also went down a lot compared to 2013. Here’s how much they decreased:
- PM2.5: down by 65.9%
- PM10: down by 50%
- Nitrogen dioxide: down by 57.1%
- Sulfur dioxide: down by 88.7%
That’s a big step towards a cleaner and healthier environment! 🌳
So, what’s the big deal? Well, cleaner air means better health for everyone—people, animals, and plants. It means more days to play outside without worrying about pollution! 🏃♀️🌞
Isn’t it awesome to see cities working hard to make the air cleaner? Maybe one day, all cities will have clean air every day! Let’s hope for more blue skies in the future! 💙
