Environment & Ecology MCQs

The technology combines advancements in material science (bio-concrete) with a deep understanding of marine biology and coral ecology to create a substrate that actively supports reef restoration.

Initial trials of the new bio-concrete technology have been conducted in the Great Barrier Reef and the Maldives, demonstrating significant improvements in coral recruitment and growth.

While coral reefs are incredibly biodiverse and provide crucial ecosystem services, their direct contribution to atmospheric oxygen production is minimal compared to phytoplankton and terrestrial plants.

The bio-concrete is engineered to be a living substrate, mimicking natural calcium carbonate and containing microbial communities that actively encourage coral larval settlement and growth, thus accelerating the reef-building process.

While other factors contribute, ocean warming leading to coral bleaching is the most significant and widespread threat to coral reefs globally, driven by climate change.

Ensuring sufficient power for autonomous drones to operate for extended periods at sea is a significant technical challenge.

The drones are equipped with sensors to monitor water quality and marine biodiversity, providing data for scientific research.

Initial deployments have been conducted in the Great Pacific Garbage Patch, a major accumulation zone for marine plastic debris.

The drones utilize advanced AI-powered visual recognition systems to accurately identify plastic waste while distinguishing it from marine organisms.

The 'Ocean Sentinel' drones are specifically designed for large-scale ocean plastic cleanup, identifying and collecting plastic debris.
