History of Economic Thought 2
To maintain economic wealth (roads, hospitals, power
lines, etc.) power needs to be consumed. The same applies to economic activity,
since any activity requires the consumption of energy. According to the Environmental Protection Agency, the burning
of fossil fuels was responsible for 79 percent of U.S. greenhouse gas emissions
in 2010. So whilst economic
activity takes place fossil fuels will be burned and CO2 emissions are
unavoidable - unless we use exclusively renewable energy resources, which is
not likely to occur very soon. However, the increasing CO2 concentrations in
the atmosphere will have negative consequences, such droughts, floods, crop
failures, etc. These effects represent limits to economic growth. The CLD
illustrates some of the more prominent negative feedback loops that act as a
break on economic growth and wealth. As the negative feedback loops (B1-B4) get stronger, an interesting question is, 'will a sharp reduction
in economic wealth and unavoidable recession lead to wide-spread food riots and disturbances?'

The World3 model is a detailed simulation of human population growth from 1900 into the future. It includes many environmental and demographic factors.

BY SETTING THE NEW ECOLOGICAL POLICIES TO 2015 WE CAN SEE THAT SOME POPULATIONS CAN BE SAVED BUT CITIES WILL SUFFER MOST.

Use the sliders to experiment with the initial amount of non-renewable resources to see how these affect the simulation. Does increasing the amount of non-renewable resources (which could occur through the development of better exploration technologies) improve our future? Also, experiment with the start date of a low birth-rate, environmentally focused policy.

Healthcare Economic System
A Tragedy of the Commons situation exists whenever two or more activities, each, which in order to produce results, rely on a shared limited resource. Results for these activities continue to develop as long as their use of the limited resource doesn't exceed the resource limit. Once this limit is reached the results produced by each activity are limited to the level at which the resource is replenished. As an example, consider multiple departments with an organization using IT resources, until they've exhausted IT capacity.
Environmental economics Niger Delta oil polluted case study
Modern industrial civilisation has created massive
interdependencies which define it and without which it could not function. We all
depend on industrial farming to produce the food we eat, we depend on gasoline
being available at the gas station, on the
availability of electricity and even on the bread supplied by the local baker. Naturally,
we tend to support the institutions that supply the amenities and goods to
which we have become accustomed: if we get our food from the local supermarket,
it is likely that we would be opposed to it’s closure. This means that the economic
system that relies on continuous growth enjoys implicit societal support and that
nothing short of environmental disaster or a shortage of essential raw
materials will impede it’s growing indefinitely. It is not hard to work out the
consequences of this situation!
