When in Doubt: The Power of Subtraction

POSTED ON July 28th, 2021 BY

“When in doubt, take it out” is a rule I apply as often as possible when editing my own writing and that of others. By removing words or seeking simpler vocabulary or constructions, writing often becomes more clear, comprehensible and even beautiful.

Subtract book cover
The suitably simple cover design for Klotz’s Subtract.

A new book by Leidy Klotz, professor at the University of Virginia, takes the idea of ‘taking away’ to a whole new level.  Subtract: The Untapped Science of Less posits that humans are programmed to solve problems by adding stuff – elements, ideas or things – whereas subtracting them often clarifies and eases a problem. One of the book’s first examples is the removal of the Embarcadero Freeway in San Francisco. The project was opposed by a majority of citizens and politicians on a number of operational and economic grounds. Yet once the freeway, damaged in the Loma Prieta quake, was removed, the benefits became obvious – and huge. Klotz notes “The decade after removal saw a 50 percent increase in housing and a 15 percent increase in jobs around the waterfront. (p. 3)  A beautiful space was created, businesses thrived, people flocked and … traffic became less snarled.

Are there environmental problems that can be addressed by removing rather than adding? Klotz addresses this possibility and gives some examples. He suggests applying subtraction to the 3Rs: “When the current situation exceeds planetary boundaries, we need to subtract first. Remove must become the first R.” (p.210)

Klotz’s research is introduced in the video below. While subtraction is not the answer to every problem, it’s another tool we can use when approaching environmental outreach…and everyday life.
