What is the aim of the first 'High Seas Treaty' signed by the United Nations?
I. To allow deep sea mining without environmental regulations
II. To protect the ocean bodies lying within national boundaries
III. To protect against potential impacts like deep sea mining

Explanation: The first 'High Seas Treaty' signed by the United Nations aims to protect the ocean bodies of the world that lie outside the national boundaries and form almost two-thirds of the world's oceans. The treaty aims to protect against potential impacts like deep sea mining. The International Seabed Authority that oversees licensing any future activity in the deep seabed will be subject to strict environmental regulations and oversight to ensure that they are carried out sustainably and responsibly. The aim is not to allow deep sea mining without environmental regulations.
