这些数字意味着什么
每张卡片都标明数据年份。历史数值是估算,不是个人预测。
In 1990, about 5.33 billion people lived on Earth. The value comes from the UN annual series; the latest comparison uses 2024.
This is life expectancy at birth under the mortality conditions of that year—not a prediction of one person's lifespan.
This counts people who used the internet within the previous three months. Early birth years use the nearest available estimate.
Area includes naturally regenerating and planted forest. A larger area does not necessarily mean biodiversity or forest quality recovered.
