How to measure atmospheric oxygen depletion

This article is more for scientists and field researchers. A practical step forward in determining global oxygen depletion rates. A conclusion to decades of research.

How long before the Earth runs out of oxygen?

Have you ever wondered how much breathable air is on Earth? And if we will ever run out? Our atmosphere is paper-thin relative to a basketball, and we use its oxygen to power internal combustion engines, like planes, trains and automobiles, and there is a 60% chance that the electricity you are using to read this post came from fossil fuels combined with oxygen.

How much oxygen do plants produce?

I calculate how much oxygen a tree breathes and how much excess oxygen a tree produces in three different ways. Spoiler alert: It’s not a lot.

How much oxygen is in the atmosphere?

I demonstrate how to calculate the mass of oxygen in the atmosphere. And I talk about ten reasons why the accepted values may be wrong.

Human Population Growth Chart

This graph illustrates the exponential growth of the human race and the consumption of non-renewable resources. The question isn’t if the population will stop growing/consuming, but when?

Is the oil spill a good thing?

Here’s an exercise in thinking positive using the BP oil spill as an example. Also, it seems one of the byproducts of traveling the world is a desire for social activism, because I never imagined thinking of stuff like this.

How much oxygen does a car burn?

We are all aware of our reliance on fossil fuels and their byproduct of greenhouse gases and poisons. But have you ever wondered about the oxygen needed to burn the fuel?

Introduction to global oxygen depletion

As mankind burns more and more fuel, we are also burning more and more oxygen. Simultaneously, the Earth’s ecosystem is being destroyed. At what point does the Earth reach a tipping point? And, how long before we run out of air to breathe?

Sustainable Futures

I recently did an in-depth interview in Vancouver for Sustainable Futures with Ryan Fletcher. This two part episode features stories of my travels framed in the context of creating a sustainable future and the rise of a global consciousness.
