Three side-by-side cards build up one at a time. In a forest, trees are cut and replanting puts seedlings in their place. In the sea, a boat keeps only some fish under a catch limit, and the fish left have young. At a lake, a tap lowers the water until saving water and rain refill it. The video ends on the recap "Take no more than nature can replace", with each card labelled with the practice and the way nature replaces what was taken.

Transcript
What the lesson says
Forests, fish and fresh water are resources we all need.
How can we keep using them, so they last for the future?
People cut down trees to get wood.
Replanting means planting seedlings where trees were cut.
Over many years, the seedlings grow into new trees.
People also catch fish for food.
A catch limit is a rule that lets people take only some of the fish.
The fish that are left have young, and the young fish grow up.
We pipe fresh water from lakes to our taps, so the lake gets lower.
Saving water, like turning off the tap, means less water is taken.
Rain refills the lake, but that can take a long time.
Replanting, catch limits and saving water are all sustainable practices.
Sustainable practices take no more than nature can replace, so our resources last.
