Can tech save the world from climate change? Environmentalist Louise Mabulo is on a mission to find out.

Travelling across the globe, she seeks out innovative and cutting-edge climate solutions that are already making a difference.

First, we explore the future of our forests, discovering how AI-powered 'digital noses' are being used to prevent forest fires in Germany, and how data collection is revolutionising mangrove protection in the Philippines.

Next, we reveal the latest in land restoration, learning how Australian drones are transforming land recovery efforts after disasters, by planting thousands of seeds a day, and how AI and smart-sensors are being used in India to combat land degradation.

We then explore the sustainability of our cities, revealing how blockchain tech is being used to redefine waste management in Manila, and how AI-driven smart sensors are revolutionising cooling systems in Singapore, optimising energy use and cutting emissions.

Finally, we navigate the world's waters, revealing how AI is being used to reduce emissions on international shipping routes, and how robots and AI are being used in India to protect vital city water systems.
