Step 1: Read the question.
Regarding Marine Genetic Resources (MGRs) under the High Seas Treaty, what is a major point of legal dispute?
Step 2: Understand MGRs.
MGRs are genetic materials from marine life. The BBNJ or High Seas Treaty governs areas beyond national jurisdiction.
Step 3: Spot the debate.
Developing nations say these resources are the common heritage of mankind, so the benefits, including profits from genetic sequences, should be shared fairly.
Step 4: See the other side.
Industrialised nations, which fund the costly research, prefer to keep the intellectual property and profits. This clash is the core legal contention.
Step 5: Eliminate the others.
Building artificial islands, submarine depth, and the launching state definition are not the main MGR dispute.
Step 6: Conclude.
The main point of contention is the equitable sharing of benefits from genetic sequences.
Answer: The equitable sharing of benefits derived from genetic sequences.
