Why The Lagina Brothers Couldn't Dig Up The Entire Island
By Robert King
The first and most obvious reason that the Laginas can't just dig up all of Oak Island is the cost, as such an undertaking would be incredibly expensive. While the Lagina brothers have certainly made their fair share of profit over the years and get funding from various sources, it would still take a ludicrous amount of time and money to excavate the entirety of the island.
However, the main reason they can't just dig up the entire island is because such an operation would wreak havoc on the ecosystem of the island and its surroundings. To dig up everything would mean tearing down the 140 acres of forest on Oak Island and endangering all of the animals and plant life that call the island home (via History). This kind of destruction would also have long lasting effects on the ocean life surrounding the island and would be an environmental nightmare, as well as a PR crisis for the series, which is possibly the brothers' main source of income.
The Lagina brothers would never be able to secure permission for this kind of a project, and it's clear that they don't plan to try such a drastic measure anytime soon. So for now, it appears that they will keep to their predictable method of throwing darts at the map and hoping they land on the treasure they've spent their whole lives searching for.
