According to the article, jellyfish are invading the oceans near JAPAN. Fisherman in the area assert that the amount of fish and jellyfish in the waters have shifted drastically during their lifetime. There is a large abundance of jellyfish (making it difficult or impossible to fish some days) and a small number of other kinds of fish.
Humans may have caused this problem by over-fishing disrupting the balance of the underwater ecosystem. Jellyfish are eaten by some fish and compete with other species of fish. Also humans building docks, bridges, and other water infrastructures have led to a decline in habitat availability for jellyfish.

hope this helps
Answer is 1/4 of the atoms
at 0 years it would be the full amount (X)
at 10 million years you have half: X/2
at 20 million years you have 1/4 because: (X/2)/2 will equal 1/4
Will the dam stops water and fish to pass thru so it kinda messes with the ecosystem(?)
