## Facts Of Life

You know there are a lot of things we can fix in this world; we can do something about…”

David Suzuki is a scientist, environmentalist, broadcaster, and co-creator of the David Suzuki Foundation.

But some things are facts of life… those are things we have to accept and work ourselves around.”

## Exponential Growth

One of these facts, Suzuki stresses, is exponential growth:

If something is growing at 1% a year it’ll double in 70 years. 2% a year it’ll double in 35 years; 3% a year in 24 years… anything growing exponentially will double in a predictable length of time. Now I’m going to show you why all this stuff about… ‘We got to keep the economy growing’… is ultimately suicidal.”

## A System Analogous To The Planet

**1 test tube full of food**=*the planet.***Bacteria who eat the food**=*humans*.

## The Experiment:

- 1 bacterial cell is introduced into a completely full test tube.
- According to exponential growth it will divide every minute.

So at times zero there is 1 cell (bacteria). 1 minute there are 2 (cells). 2 minutes there are 4. 3 minutes there are 8. 4 minutes 16.”

## 60 Minute Growth Cycle

At 60 minutes the test tube is completely packed with bacteria and there’s no food left. So we have a 60 minutes growth cycle. When is the test tube only half full?”

**59 minutes:***50% full.*

Even though it’s been chugging along for 59 minutes it’s only half full but one minute later it’ll be completely filled. So that means that…”

**58 minutes:***25% full.***57 minutes:***12.5% full.***55 minutes:***3% full.*

## Living In The 59th Minute

Our home is the biosphere. It’s fixed and finite. It can’t grow. And we’ve got to learn to live within that finite world. Every scientist I have talked to agrees with me: We’ve already passed the 59th minute.”
