The Ocean Cleanup is a Netherlands-based, non-government environmental engineering organization that develops technology to extract plastic pollution from the oceans. They have developed a "passive" cleanup system that takes advantage of the natural oceanic forces of wind, water, and currents.

Kelp is a fascinating plant. What we see on the surface has little in common with what's actually there. Californian harbor seals are mammals but they do a lot of hunting underwater.

Everyone's heard of California, but this documentary showcases the state's natural beauty and wildlife. It has a fascinating range of geographical features and is home to many unique species of animals.

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.

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.

Dolphins are one of the smartest animal species on Earth. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. But exactly how smart are they? This video shares some incredible facts about dolphins.

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.

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.
