Q & A

What is the Earthshot Prize and what does it aim to achieve?

The Earthshot Prize is an environmental award that remains optimistic about repairing and regenerating our planet this decade. It sets out five challenges to drive essential solutions for the Earth's most pressing issues.

How does climate change impact the Great Barrier Reef?

Climate change impacts the Great Barrier Reef by causing an excess of carbon dioxide in the water and a rise in ocean temperatures, leading to widespread coral bleaching and devastation for marine ecosystems.

Who are the Indigenous Australian women contributing to the conservation of the Great Barrier Reef?

The Indigenous Australian women contributing to the conservation are led by Larissa Hale, an Indigenous Land and Sea Ranger in Archer Point, Cape York, Australia.

What is the Queensland Indigenous Women Ranger Network and what is its purpose?

The Queensland Indigenous Women Ranger Network is a group supported by the government to provide culturally appropriate training for women to manage their land and sea country using technology.

How does the Great Bubble Barrier project in the Netherlands address ocean pollution?

The Great Bubble Barrier project catches plastic pollution in rivers before it enters the ocean using a perforated tube that creates a curtain of bubbles to bring plastic to the surface, where it can be collected.

What is the significance of seaweed forests in the context of climate change?

Seaweed forests, particularly kelp forests, are significant because they can absorb CO2 at least five times more efficiently than tropical forests on land due to the rapid growth of algae.

What is Seaforester and how does it propose to restore seaweed forests?

Seaforester is a solution that aims to restore seaweed forests using innovative seaforestation techniques, such as 'green gravel,' which involves seeding small stones with seaweed spores and deploying them at sea.

How would winning the Earthshot 2022 Prize benefit the finalists?

Winning the Earthshot 2022 Prize would provide the finalists with opportunities for more training, accelerate the implementation of their solutions, and show that their work has value and should be scaled and implemented globally.

What is the role of human ingenuity and nature in the solutions presented by the finalists?

The finalists' solutions showcase the role of human ingenuity in developing innovative technologies and strategies, while also highlighting the importance of nature's ability to regenerate and recover when given the right support.

Why is it crucial to protect and revive our oceans according to the script?

Protecting and reviving our oceans is crucial because they are one of the most threatened environments on our planet, yet they are essential for our survival, supporting a vast array of marine life and ecosystems.
