In Tokyo, there are unapproachable "lost islands" with unspoiled environs and rich wildlife. Minami Iwo-to, part of the Ogasawara island chain, is about 1,300km from the Japanese capital. Normally, entry is banned to protect the environment. An exception was made in 2017 for the first comprehensive scientific survey in 10 years. The island compresses multiple climate zones into a small area, offering researchers a rare opportunity to view evolution in action. Braving an arduous climb and a swarm of seabirds, the team discovers one new species after another.
In three decades, the waters around the remote village of Cabo Pulmo have gone from wildly biodiverse, to barren, to a bountiful and pristine haven for mighty sharks and flying rays once again. See how local fishermen ultimately turned back the clock, restoring one of the world's most majestic coral reefs.
With every step towards the summit of the mighty Drakensberg, new species of exotic animals showcase the attributes that enable them to endure their harsh mountain home. Meet the sungazer, the intriguingly named suicide lizard, and other reptiles that inhabit South Africa's high-altitude terrain.
Traveling is extremely arduous for microscopic sperm -- think of a human trying to swim in a pool made of...other humans.
Life and Death explores the impact of Darwin’s ideas on our understanding of the meaning of extinction and the interconnections between all life on earth and the environment. Darwin learned many lessons from the giant fossils of extinct animals he found in Argentina and Chile. He eventually revealed to us the unpalatable truth that the logical conclusion to evolution is not perfection but extinction. The extinction of one species creates an environmental niche for new species to fill. Darwin’s theory also gives us vital knowledge we can use to help prolong the existence of our species by respecting the interconnections between all elements of the natural world and the environment. It’s a story in which Darwin’s ideas are taken up with great enthusiasm by his followers throughout the 20th century. But humanity misses one opportunity after another to acknowledge and reduce its destructive impact on the planet. As a result we have set in motion the sixth mass extinction of life on earth. And we are running out of time to do something about it by preserving ecological "hotspots" like certain rainforests which are some of the most productive cradles of evolution. This programme is a warning, but also a celebration, of the knowledge Charles Darwin gave us in his theory of evolution. It confirms that Darwin’s theory continues to inform our understanding of ourselves, our planet and the intricate interconnections between all life on earth.
