As A Lifeboat : The Metaphors Of A Lifeboat

Good Essays

The metaphor of a spaceship is discarded by the metaphor of a lifeboat in Hardin’s writing; each nation on Earth is considered a lifeboat. The wealthy are living in the lifeboats. The poor are drowning in the waters. Poor nations are unable to let people on their lifeboats. There needs to be a solution for this issue. The nations with wealth have limited resources, so they cannot afford to let the number of poor people on their lifeboat. The poor nations have already reached their capacities. If the wealthy nations let the poor into their boat, then their resources would get used up, resulting in the sinking of their lifeboats.
A lifeboat has a limited capacity. When the capacity is reached, incoming passengers will be forced to swim.

The imagery serves as a good metaphor for Earth when used to convince others about the importance of our Earth’s sustainability, because there are those who have not recognized the Earth as a lifeboat.

In the metaphor, these nations have to throw people off of their lifeboats. People feel the need for responsibility to look after their belongings, such as private property. If they have no responsibility for their belongings, then they would eventually lose them due to lack of maintenance. “Tragedy of the commons” is a group behavior that derived from Hardin’s analysis on the flaws of the “spaceship ethics.” For example, if there is a property that belongs to a large group of people, then according to the “tragedy of the commons,” there will be people who have different priorities. The “tragedy” will reveal people who will feel different amounts of responsibility. The easiest examples of shared property are the air and the oceans. Both of them are the easiest to name, because we know they are
