In this short animation, produced for primary school children by Green.TV, supported by the Wellcome Trust, we look at the remarkable evolution of the whale from a land-based dog-like animal to the marine mammal that became the world’s largest creature ever.

Anne-Marie shows us a section of a “Kata,” a series of defensive moves designed to fend off multiple attackers. Then she applies these techniques with Alex playing the role of the attacker as she demonstrates a part of the “Bunkai.”

The series draws to a close with footage of apes, the most direct ancestors of humans. The narrator nicely sums up the meaning of evolution and man's place in nature.

It’s radio presenter Roman Kemp’s turn to learn some moves from Anne-Marie. He sounds worried when she mentions “nunchucks” and “knife defense”, but he just isn’t taking his lesson seriously, and keeps distracting her. Eventually she suspects he’s done some karate before, and maybe isn’t such a complete beginner.

Boris Johnson is the UK's new prime minister. Known as "BoJo" among his supporters, he's one of the UK's most recognizable politicians. He's a charismatic, and sometimes controversial figure. Johnson started his career in journalism, but was fired from The Times for making up a quote. He was elected as a Member of Parliament in 2001.

Rhinoceroses, or rhinos for short, are the largest land animals after elephants. Five species remain (two in Africa and three in Asia) and all are endangered as a consequence of the illicit trade of their horns. The importance of rivers is another focus of this segment.

Anne-Marie is a successful singer and songwriter, and she believes that all the hard work, discipline, and focus learned while becoming a black belt in karate has prepared her well for her busy life. She clearly loves her teacher Jo, and her sport, in which she has won gold medals at World Championship level.

The focus of this segment is on animals of the African savanna. We get to see giraffes and elephants, the largest of the land creatures, as well as cheetahs, the fastest.

The video starts with information about coastal geology and the evolution of birds. It includes amazing footage of white storks, wildebeest, as well as zebras in East Africa's Serengeti region.

World Wildlife Fund: Making sustainability a priority, the Marshik Dairy — a fifth-generation family farm — implemented a new, technologically advanced and energy efficient barn design for their 155 cows. The new design included robotic milking facilities, energy efficient lighting and ventilation, and renewable wind and solar power.

California sea lion communication, mating habits, and past and present threats to their survival are discussed. This segment additionally features amazing aerial photography of their rocky coastal habitats.

Here's a video from the World Wildlife Fund. Traditionally, anaerobic digester systems have not been practical on small dairy farms, but this didn’t stop Sensenig Dairy, a 100-cow farm, from pursuing its goal. Then Sensenig teamed up with the local community to collect enough waste to produce 1,401,600 kilowatt hours of electricity per year from "trash" that would otherwise end up in a landfill.

Marine mammals are the focus of this segment on coastal sea life. Humpback whales mostly swim along the coasts, whether in the Northern or Southern Hemisphere. Seals are semi-aquatic and try to stay as close to the coast as possible, though they'll search for prey in depths of up to forty meters.

Subscribers love playing Scribe, Yabla's patented dictation game. Once you've watched this brief video, you'll be playing in no time.

We learn about the thousands of kilometers that humpback whales travel from their summer habitat in the polar regions to the tropical or subtropical waters where they spend the winter. Their multi-versed songs and the markings on their flukes are also discussed.
