• • Sustainability: The technology minimizes the use of harmful chemicals, making it an eco-friendly solution.

Significance of the Initiative

Why is Clean Water Important for Zoos?

Zoos, especially those with aquatic species, require pristine water conditions to mimic natural habitats. Polluted water can lead to:

• • Algal Blooms: Excessive growth of algae that depletes oxygen, endangering aquatic life.
• • Health Hazards: Accumulation of harmful bacteria and pathogens.
• • Aesthetic Concerns: Dirty water impacts the zoo’s visual appeal and visitor experience.

With Nano Bubble Technology, the National Zoological Park can maintain cleaner water bodies, ensuring better health for aquatic animals and enhancing biodiversity within the zoo ecosystem.

Trial and Testing of Nano Bubble Technology

The technology will undergo a 15-day trial period at the National Zoological Park. This phase will:

• • Assess Effectiveness: Determine the technology’s ability to clean water and remove algae.

• • Measure Impact on Animals: Ensure that the aquatic species exhibit improved health and activity.

• • Identify Scalability: Evaluate its potential application in other water bodies across zoos nationwide.

What is a Zoological Park?

A zoological park, commonly referred to as a zoo, is a facility where animals are housed, cared for, and displayed for public education, recreation, and conservation purposes. Key features include:

• • Biodiversity Conservation: Zoos protect endangered species and conduct breeding programs.

• • Research and Education: They facilitate research on animal behavior and ecology while educating the public on wildlife and environmental conservation.

• • Recreation: Zoos serve as recreational spaces for visitors to observe and appreciate diverse wildlife.

• The National Zoological Park in Delhi, established in 1959, is a prominent facility housing over 1,300 animals and birds from around the world. It is asignificant site for education and wildlife conservation in India.

How Nano Bubble Technology Aligns with Sustainable Goals?

This initiative reflects India’s commitment to integrating modern technology with environmental conservation:

• • Sustainability: By reducing chemical dependence, it aligns with eco-friendly practices.
• • Improved Animal Welfare: Healthier water ensures the well-being of aquatic species.
• • Global Leadership: Adopting innovative solutions positions India as a leader in wildlife conservation technologies.

The Broader Implications for Environmental Conservation

• If successful, the deployment of Nano Bubble Technology could pave the way for its application in other areas, such as:

• • Cleaning polluted lakes and rivers.
  • Enhancing aquaculture practices.
  • Revitalizing urban water bodies.

Conclusion

• • The launch of Nano Bubble Technology at the National Zoological Park in Delhi marks a significant milestone in combining technology with environmental conservation.

• • As it undergoes testing, this initiative has the potential to redefine water management practices in zoos and beyond, ensuring cleaner habitats and healthier aquatic ecosystems.

• For UPSC aspirants, this development serves as a case study in sustainable environmental practices, technological innovation, and the role of modern zoos in biodiversity conservation.

Which of the following best explains the principle behind the self-collapsing functionality of Nano Bubble Technology?

Thermal expansion of gas bubbles leads to chemical reactions.

Surface tension causes the collapse of nanobubbles, releasing energy that dislodges impurities.

Nanobubbles absorb contaminants directly and burst to trap them in microplastics.

Pressure from the water column compacts bubbles, which dissolve toxins.

Correct Answer: B) Surface tension causes the collapse of nanobubbles, releasing energy that dislodges impurities.
