Tragedy Of Commons Flashcards
tragedy of the commons
Understanding the degradation of our environment
If a resource is held in common for use by all, then ultimately that resource will be destroyed freedom in a common brings rolling tall. To void the ultimate destruction, we must change our human values and ideas of morality.
“Held in common”
The resources on by no one, or owned by a group, all of whom have access to the resource
“Ultimately”
After you many years, maybe centuries the time interval is closely tied to population increase of who have access to the resource the greater the number of people using a resource the faster it is destroyed.
How can we avoid tragedy ?
By altering our values, by changing the way we live. There is no technical solution
Examples of common resources
Air. No one owns the air it is available for all to use.
Water. Water in the seas in the ocean is a common resource.
Fish of the sea.
No Technical solution
The tragedy of commons is an example of this it may be defined as one that requires a change only in the techniques of the natural sciences, demanding little or nothing in the way of change in human values or ideas of morality.
Solving common problems involves two distinct elements:
- Distracting access, and
2. creating incentives (usually by signing individual rights to, or shares of, the resource)
Our ability to notice changes determined by our?
Baseline
Shifting baseline
It colors or ability to notice environmental change because changes often slow, spanning generations.
Examples of shifting baselines
- People were once uncommon. It was possible to walk for days without meeting another person. Now, it is possible to walk for days without getting out of an urban area.
- Fish were once extremely plentiful.
- Streams and rivers were crystal-clear.
- There was clean.
- Our skies are polluted by like we once stood in all of the night sky with millions of stars but across the back vastness of space.
Climate
Has been defined as the average weather: temperature, precipitation, cloudiness, and how these variables change throughout the year.
Why is the ocean and important part of the earth system?
It influences the transformation of energy and materials important to the climate system. How did the most basic level of the ocean has shaped your atmosphere. Over millions of years the concentration of gases in the atmosphere is determined by life if life did not exist especially life in the ocean earth would be very different.
Before photosynthesis, the air and oceans were?
Anoxic.
Anoxygentic and oxygenic
(Not producing oxygen) and then of oxygenic producing oxygen photosynthesis, sharply increased the productivity of the biosphere
certain forms of bacterial photosynthesis
Oxygen and that must feel led to the formation of the Stratospheric ozone layer… which protects all life from?
Solar ultraviolet radiation
