Explique por que as passagens maritimas possuem importancia economica e geopolitica

The economic and geopolitical importance in the maritime passages is in the fact that they control the trade.

Explanation:

There are many maritime passages around the world, and all of them are very important, though some more than others. The reason as to why these passages are so important is that they control trade, be it regionally or globally, so the countries that control them have enormous power.

The power is main in the economic and geopolitical aspect. By controlling the trade, not just that there are huge amounts of money going into the budgets of these countries, but they also have the ability to damage the other countries if they strip them of the right to use the passages, which in turn gives them even larger geopolitical power.
