should aquatic creatures be completely disappeared after the appearance of terrestrial creatures

The concept of aquatic creatures disappearing after the appearance of terrestrial creatures is not a beneficial or appropriate notion from an ecological or ethical perspective. Both aquatic and terrestrial life forms are integral components of Earth's biodiversity and play irreplaceable roles in the planet's ecosystems.

1. Biodiversity: The variety of life on Earth, including both aquatic and terrestrial species, contributes to a stable and healthy environment. Each species has a unique genetic makeup that can adapt to changing conditions, which is crucial for the resilience of ecosystems.

2. Ecosystem Services: Aquatic ecosystems provide essential services such as water purification, nutrient cycling, and climate regulation. These services are vital for the survival of all life forms, including terrestrial creatures.

3. Interdependence: Terrestrial and aquatic ecosystems are interconnected. For example, rivers flow from land to sea, carrying nutrients and organisms, highlighting the interdependence of these environments.

4. Food Chains: Aquatic creatures are a significant part of marine food chains and support a vast array of other species, many of which are also utilized by humans for food.

5. Cultural and Spiritual Value: Many cultures around the world have a deep spiritual connection with aquatic environments and their creatures, which adds another layer of importance to preserving these life forms.

6. Scientific and Medical Knowledge: Aquatic species contribute to our understanding of evolution, genetics, and ecology. They also serve as a source of new medicines and treatments.

7. Ethical Considerations: From an ethical standpoint, the idea of allowing one group of living beings to disappear simply because another group has evolved is not supported. Each species has value in its own right and contributes to the richness of life on Earth.

8. Environmental Stewardship: It is our responsibility to protect and conserve all forms of life, ensuring that future generations can appreciate the diversity of species that exist today.

Therefore, instead of considering the disappearance of aquatic creatures, we should focus on conservation efforts that ensure the continued survival and prosperity of all life forms, both aquatic and terrestrial. This approach aligns with the principles of sustainability and biodiversity preservation, which are essential for maintaining the balance of our planet's ecosystems.
