The U.S. Department of Defense has plans for 5,000 marines to train on Pågan, as part of the Obama administration's move towards the Asia-Pacific.
The island is located just 1,600 miles off the coasts of the Philippines
Not only will the military exercises make human settlement impossible, but it could destroy the ancient cultural monuments and endangered wildlife that remain on Pågan.
The move is part of a plan to reduce and relocate U.S. military presence in Okinawa, Japan.
Dozens of families and former residents of Pågan teamed with environmental activists to launch a lawsuit against the Pentagon's plans.
Few Americans are aware of the disruption U.S. military drills involving artillery and bombs have had on the 3,000 residents Pågan Island and nearby Tinian Island.
Activists hope to preserve their home and culture that has existed for 1,300 years.

The Burj Kahlifa, the world's tallest building in Dubai, United Arab Emirates.
Situated in downtown Dubai, the building was completed in October 2009. The building stands 829.8 metres tall, 2,722 feet. Visitors to Dubai can visit the buidling, with an observation deck on the 124th floor, named 'At the Top'. The views from the deck are stunning and give an amazing view of the surrounds of Dubai. The lift taking visitors to the deck hurtles guests at top speed and then allows them space outside to view the surrounds. There are 24,348 windows in the building. The building dominates for miles around and is truly a spectacular building of our day.
