01:29 In 2019, the Greenland ice sheet was experiencing its largest melt in recorded history: 200 billion tons of ice liquified into the ocean. When glacial ice melts, caving icebergs release sediments and particles into the seawater, initiating our ocean's food chain. Plankton feed on the sediment, krill eat plankton, and the humpback whales feed on the krill. This photograph is the result of w..

00:09 Nature reveals itself to us in unique ways, if we stop and look at the world through a window of time. 00:17 Over the last decade, I've observed endangered species and habitats around the world, using a photographic technique that captures the passage of time, literally from day to night, all within a single image.

Since Calcutta's core has no formal treatment, it's the city's only way of cleaning the water downstream before it enters the Bay of Bengal. What I find so unbelievable about this infrastructure is that as cities across the world in Asia and in Europe begin to replicate this exact system, Calcutta is ..

03:25 Although global attention is focused on the pandemic, cities are still sinking and sea levels are still rising. And high-tech solutions are definitely going to help us solve some of these problems, but in our rush towards the future, we tend to forget about the past. 03:43 In other parts of the world, where rivers are contaminated with sewage, a city of 15 million people cleans its waste w..

It is food for water buffalo, flour for humans and building material for these biodegradable, buoyant islands and their cathedral-like houses that they construct in as little as three days. And this dried Qasab reed, it can be bundled into columns, it can be woven into floors or roofs or walls, and it can also be twisted into a rope t..
