What are some potential challenges or conflicts that could arise from the vesting of resources within India's exclusive economic zone to the Union under Article 297?
Some potential challenges or conflicts that could arise from the vesting of resources within India's exclusive economic zone to the Union under Article 297 include:

1. Balancing national interests with those of individual states: Since all resources in the exclusive economic zone are vested in the Union, there may be conflicts between the central government and state governments when it comes to managing these resources. State governments might feel that their interests are not being adequately represented or protected by the Union's decisions regarding the utilization and management of these resources.

2. Environmental concerns: The exploitation of resources within the exclusive economic zone may lead to environmental degradation, which could cause conflicts between different stakeholders, including industries, local communities, and government agencies responsible for environmental protection.

3. International disputes: As India's exclusive economic zone overlaps with those of neighboring countries, there may be potential for international disputes over the management and utilization of shared resources. This could lead to diplomatic tensions and even military conflicts if not managed carefully by both parties.

4. Economic disparities: The vesting of resources within the exclusive economic zone in the Union might create economic disparities between different regions, as some states may benefit more from these resources than others. This could lead to social unrest and calls for greater autonomy or resource allocation at the state level.

5. Overexploitation and depletion of resources: With all resources vested in the Union, there might be a tendency towards overexploitation and unsustainable use of these resources, leading to long-term environmental damage and depletion of valuable assets for future generations.
