With example shows an organism that cannot reach home ocean in cases through eternal changes
One example of an organism that cannot reach its home ocean due to external changes is the loggerhead sea turtle. These turtles have a strong homing instinct and use Earth's magnetic field to navigate back to their natal beaches when it's time to lay their eggs. However, with increasing human development along coastlines, artificial lights and other disturbances can disorient the turtles and prevent them from finding their way back to their nesting sites.
For instance, if a coastal area where loggerhead sea turtles typically nest undergoes significant changes such as the construction of buildings or roads, the turtles may not be able to recognize their usual nesting grounds. This can lead to them laying their eggs in unsuitable locations or becoming disoriented and failing to return to their home ocean after nesting.
In such cases, conservation efforts are crucial to help protect and preserve the habitat of these turtles and mitigate the effects of human development on their ability to successfully navigate back to their home ocean. This can include implementing measures to reduce light pollution, creating and maintaining safe nesting beaches, and educating the public about the importance of conserving loggerhead sea turtle populations.
