When Science Gives Trends Purpose

cornfield

I, among fellow students in my graduate program, have had the recent pleasure of learning about the ‘ecology of managed ecosytems’ from the most cited ecologist in the world: Dr. David Tilman. What is it about Dr. Tilman’s science that has propelled him to the top of the ecologist’s food chain? According to him, it was [...]

Is Sustainable Development an Oxymoron?

In a recent post on the Rio +20 Summit, Nick said “Getting so many people together in one room to decide how to continue increasing economic growth without damaging the planet may not be possible.” Indeed there are numerous barriers, both physical and ideological, to getting all sides to the table to discuss a future [...]

EIA Releases 2012 Annual Domestic Energy Outlook

In June the Energy Information Administration (EIA) released its 2012 Annual Energy Outlook (PDF). According to the press release, the report includes various “assumptions regarding market, policy, and technology drivers affect projections of energy production, consumption, technology, and market trends and the direction they may take in the future.” Among the most pertinent projections for [...]

Are Cities Really More Sustainable?

In the most recent Five Friday Facts, Justin provided information on the growth in cities outside the developed world. He points out that increasing populations pose challenges for sustainability. How can we support a global population in denser cities? The argument tends to go that cities are more sustainable since they use less land to [...]

How to Feed Our Growing Population

The world just reached (and flew by) the day when the 7 billion people inhabited the Earth.  7 billion people, that is hard to imagine or comprehend.  The crazy thing is, people are not going to stop reproducing anytime soon; current speculation is we will reach 9 billion by 2050.  2050 is not very far [...]

While it is not possible to know when, who, or where exactly the seven billionth member of our current population will be born (it may or may not be today, this month, [...]

Carrying Capacity: The Missing Link in Sustainability

Carrying Capacity

A few of our previous op-ed pieces have touched on keys to sustainability (including resilience and durability) and where sustainability is today. Often sustainability is conflated with the “green” movement. However, rarely does anyone discuss weak vs. strong sustainability. The former is largely where we are today, substituting human capital for natural. One could argue [...]

Five Friday Facts: Bottlemania Water Facts

While in between books for school, I picked up a copy of Elizabeth Royte’s Bottlemania. I had previously read (and reviewed) her book Garbage Land. Through two chapters, I have thoroughly enjoyed Royte’s writing and introduction to bottled water. This first set of Five Friday Facts from the book provides an overview of water issues [...]

Five Friday Facts: The Nature of Design

A friend recently lent me her copy of David Orr’s The Nature of Design. I read and reviewed his 1994 book, Earth in Mind several months back. In the first few chapters there were a number of interesting facts. I culled a few from Earth in Mind for a past Five Friday Facts and noted [...]

The False Promise of Efficiency

Energy efficiency is not enough. While it is an integral part of an energy management plan and an essential first step to reducing energy consumption and increasing economic savings, a look at the overall consumption of energy, especially from non-renewable sources, indicates that society has failed to make a significant dent in the total energy [...]
