Earthling — Renewable Living Resources Timber Trail

Hi!

I'm Earthling.

Welcome to Timber Trail!

Will you help me investigate renewable living resources?

The Grumblies have mixed up our clues.

Let's check the evidence!

Living resources such as trees and crops can regrow.

They are renewable only when the conditions

and time needed for renewal are available.

What makes trees a renewable resource?

  • A. They can never run out locally
  • B. They grow instantly
  • C. They can regrow

The answer is C: They can regrow

Living resources such as trees and crops can regrow.

They are renewable only when the conditions

and time needed for renewal are available.

That clue helps us make sense of this place.

Using a resource faster than it regrows can reduce the supply.

Renewable does not mean unlimited or impact-free.

What happens in the given 10-in, 20-out model?

  • A. The count stays unchanged
  • B. The counted supply declines
  • C. The supply grows

The answer is B: The counted supply declines

Using a resource faster than it regrows can reduce the supply.

Renewable does not mean unlimited or impact-free.

Hmm...

how does that connect to our first clue?

Our simplified forest record adds 10 trees

while 20 are harvested during the same period.

That pattern reduces the counted trees;

a better plan considers regrowth and habitat needs.

What should a harvest plan consider?

  • A. Regrowth and habitat conditions
  • B. Only today's demand
  • C. Only the label color

The answer is A: Regrowth and habitat conditions

Our simplified forest record adds 10 trees

while 20 are harvested during the same period.

That pattern reduces the counted trees;

a better plan considers regrowth and habitat needs.

Nice investigating!
