Study highlights snowball effect of overfishing

Study highlights snowball effect of overfishing | Sustain Our Earth | Scoop.it

Tallahassee, FL (SPX) Jan 14, 2014 - Florida State University researchers have spearheaded a major review of fisheries data that examines the domino effect that occurs when too many fish are harvested from one habitat.

 

The loss of a major species from an ecosystem can have unintended consequences because of the connections between that species and others in the system. Moreover, these changes often occur rapidly and unexpectedly, and are difficult to reverse.

 

You don't realize how interdependent species are until it all unravels," said Felicia Coleman, director of the Florida State University Coastal and Marine Laboratory and a co-author on the study.

Why EIA, IEA, and Randers' 2052 Energy Forecasts are Wrong

Why EIA, IEA, and Randers' 2052 Energy Forecasts are Wrong | Sustain Our Earth | Scoop.it

What is correct way to model the future course of energy and the economy? There are clearly huge amounts of oil, coal, and natural gas in the ground.  With different approaches, researchers can obtain vastly different indications. I will show that the real issue is most researchers are modeling the wrong limit.


Most researchers assume that the limit that they should be concerned with is the amount of oil, coal, and natural gas in the ground. This is the wrong limit. While in theory we will eventually hit this limit, because of the way fossil fuels are integrated into the rest of the economy, we hit financial limits much earlier. These financial limits include lack of investment capital, inability of governments to collect enough taxes to fund their programs, and widespread debt defaults.
