Let us not, however, flatter ourselves(自命不凡,自以为是) overmuch on account of our human victories over nature. For each such victory nature takes its revenge [r vend ] on us.
—Friedrich Engels / fri dr k e ɡ lz/
但是我们不要过分陶醉于我们人类对自然界的胜利。对于每一次这样的胜利，自然界都对我们进行报复。

Now is the time to sound the alarm.
We want to live in a world that’s clean;
We want to live in a world of green.
The human race has done much harm;
Now is the time to sound the alarm.
Let’s be thankful for the skies above;
Let’s plant new trees and stop pollution;
Let’s work together to find the solution;
The Earth’s our home to protect and love.
