这是2026年2月24日，农历正月初八，年后口语粉碎机打卡《Our Planet》主题第一天。
Just 50 years ago, we finally ventured to the moon. For the very first time, we look back at our own planet. Since then, the human population has more than doubled. This series will celebrate the natural wonders that remain, and reveal what we must preserve to ensure people and nature thrive.

For generations, this stable Eden nurtured our growing civilizations. But now, in the space of just one human lifetime, all that has changed. In the last 50 years, wildlife populations have, on average, declined by 60 percent.
