Global warming affects most people in the world,
especially those living in low-lying areas near the
sea. It has been predicted that the melting of polar
ice may cause the sea to rise by as much as twelve
metres by 2050. This would cause flooding in many
major coastal cities, such as Tokyo. It has been
suggested that the best solution to this problem may
be for mankind to become amphibious, like frogs. It is
argued that life was originally found in the sea, and so
it would merely be a return to our original habitat.
