Coastal erosion has depleted a large portion of South Louisiana's wetlands along the coastline in swamps and marshes mainly due to storm surges. But other factors also contributed to this erosion. Canals and waterways dug through the marshes and swamps for the oil industry is one factor. Man-made levees erected to provide protection to residents living adjacent to the river is another major cause. Large scale logging especially in the early 1900's also damaged the wetlands.

First, we need the distance of Europe and Wolf-359 from Earth.
- The distance of Europe from Earth is:

- The distance of Wolf-359 from Earth is instead 7.795 light years. However, we need to convert this number into km. 1 light year is the distance covered by the light in 1 year. Keeping in mind that the speed of light is

, and that in 1 year there are
365 days x 24 hours x 60 minutes x 60 seconds =

, the distance between Wolf-359 and Earth is

Now we can calculate the time the spaceship needs to go to Wolf-359, by writing a simple proportion. In fact, we know that the spaceship takes 2 years to cover

, so

from which we find

, the time needed to reach Wolf-359:
