Ep 18. Sex, Drugs and Plants

In the 18th episode of National Geographic Documentaries season 2011 titled "Sex, Drugs and Plants," viewers are taken on a journey through the fascinating world of plants and their relationship with animals - specifically, how they use chemicals such as pheromones to attract mates and defend themselves from predators.

The episode begins with a look at the bizarre and intricate process of how various plants use pheromones to manipulate and attract the animals that will help them reproduce. From the orchids that mimic female wasps to lure male wasps into pollinating them, to the night-blooming flowers that rely on the scent of bats to spread their pollen, viewers are treated to a stunning array of tactics that plants have developed to propagate themselves.

As the episode progresses, the focus turns to the darker side of plant-animal interactions, namely the use of toxic chemicals to deter predators. Viewers are introduced to deadly plants such as the poison dart frog and the Wollemi pine, which produce potent toxins that are used as a defense mechanism against would-be herbivores.

But the most fascinating aspect of this episode is its exploration of the complex relationship between plants and humans. From the ancient Egyptians' love of opium to modern-day cocaine addiction, humans have been drawn to the psychoactive properties of certain plants for centuries. This segment delves into the history and science behind some of the most famous drugs derived from plants, including cocaine, opium, and marijuana.

Throughout the episode, expert botanists and scientists provide insight into the incredible science behind the complex relationships between plants and animals. Viewers are treated to stunning footage of the plant kingdom, from the lush rainforests of South America to the desolate Australian outback, as well as fascinating interviews with experts in the field.

Overall, "Sex, Drugs and Plants" is a thought-provoking and visually stunning exploration of the fascinating world of plant-animal interactions. Whether you're a nature lover, a science buff, or simply curious about the natural world, this episode is a must-watch.
