One new power plant is aiming to change that. Copenhagen's new waste-to-energy plant, the Amager Resource Center built by the Bjarke Ingels Group will have both a ski slope and a rock-climbing wall on its modern exterior, while inside, household waste is incinerated and turned into energy. It's a relatively clean process, but still one that generates CO2.

Photosynthesis Animation for Kids
This introductory, animated video explains the process of photosynthesis by which plants take in sunlight, carbon dioxide and water to produce their foodand Oxygen. Suitable for learners/kids new to the concept.

ees pollinate a third of everything we eat and play a vital role in sustaining the planet's ecosystems. Some 84% of the crops grown for human consumption - around 400 different types of plants - need bees and other insects to pollinate them to increase their yields and quality. These include most fruits and vegetables, many nuts, and plants such as rapeseed and sunflowers that are turned into oil, as well as cocoa beans, coffee and tea. Crops grown as fodder for dairy cows and other livestock are also pollinated by bees. And it's not only food crops that rely on bee pollination, cotton does as well. As a result, annual global crop pollination by bees is estimated to be worth $170bn.

A really interesting video that can be used to teach natural selection. Discusses many of the behaviors of plants that help them to survive, thrive and reproduce.

Discover the hormones that dictate whether a plant grows downwards with gravity, towards water and nutrients, or upwards towards light.

SciShow describes the fascinating science of Darwin's little darlings: meat-eating plants. Learn about their many different types, how they catch and eat their prey, and how scientists think they evolved.

Discover one of the most unique hunters of the plant kingdom, and witness how the cobra lily (Darlingtonia californica) uses deception and patience to trick unsuspecting insect prey into its highly specialized pitcher traps.

Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven't we made the switch? The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides explains how solar towers and panels create electricity and how scientists are trying to create a system that can function even under cloud cover.

Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we're pretty fond of as well.

Photosynthesis is an essential part of the exchange between humans and plants. Amanda Ooten walks us through the process of photosynthesis, also discussing the relationship between photosynthesis and carbohydrates, starch, and fiber -- and how the air we breathe is related to the food we ingest.

When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal poop contribute enormous amounts of energy to our ecosystems

An interesting bit on efforts to clone a giant redwood tree and plant saplings from that tree in an effort to increase the amount of carbon absorbed from the environment.

This video goes over the structures and functions of flowers and how they produce fruit.
