One Finite Planet

Environment: Journey to grok One Finite Planet.

Environment: Journey to grok One Finite Planet.

While throughout history there have been people who realised the Earth was finite, too few have stopped to fully contemplate grok the concept. Grok that the area of the Earth is finite, that the resources of the Earth are finite, and the time the Earth will exist is finite.

It was not until the 1700s that a significant number of people in different countries could even accurately picture the planet entire planet and appreciate the surface was finite, and not until the 1900s that the term 'sustainability' attracted significant attention, and people started to appreciate how resources are finite.

This missing piece in this picture is still time, with most people still having a time horizon that allows time for our planet can be considered infinite, even though finite, and there is less than 2% of time remaining for life on Earth.

One Finite Planet: Beyond Sustainability.

One Finite Planet: Beyond Sustainability.

Our planet is finite. There is a finite surface, finite resources, and even finite time. On a planet without humans, there would be as little as 25 million years remaining for any complex life. It took until around the 1700s for many to know the finite surface, and until the 20th century for many to consider implications of finite resources and think sustainability. One finite planet is about the next step: recognising that time is also finite and, even provided humanity does nothing to end things prematurely, there is as little as 2% of the time Earth can support now remaining. Sustainability alone, is a death sentence.

Births Per Woman: Not quite what you would expect.

This is an exploration of what ‘births per woman’ means, and how it is measured. Key to discussion about population is population growth, which is most commonly analysed from ‘births per woman’, which is also called ‘fertility rate’. But what is ‘births per woman’? Answer: not quite what you might expect, which means a small adjustment is required for interpreting births per woman when predicting population growth.
