Water is used by everyone, and in the process, a lot of it goes to waste. Whether it goes down drains, sewers, or toilets, much of it ends up at a wastewater treatment plant where it undergoes rigorous cleaning before it flows back to the environment. The process takes time, money and a lot of energy. What if that wastewater could be turned into energy? It almost sounds too good to be true, but environmental engineer Bruce Logan is working on ways to make it happen. With support from the National Science Foundation, Logan and his team at Penn State University are taking the idea a step further. They are developing microbial fuel cells to channel the bacteria's hard work into energy.

This program explores how arthropod biodiversity helps humans. Insects are both producers and decomposers, and these functions are essential to the health of the planet. Part of the "Backyard Bugs & Other Arthropods" series.
The business world has forced agricultural researchers and producers to improve production systems by either increasing the quality of the product, size, or growth process. All these issues are part of the concept of Biotechnology.
In an effort to improve the quality of educational content in Colombian University Television, The History Channel Experience was held. This workshop was designed to motivate producers and Colombian University filmmakers to use international production systems in their presentations and in the development of audiovisual projects.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, food experts reveal how fair trade certified foods ensure proper economic development for all food producers. Part of the Nourish Short Films Series.
Host Steve Backshall takes a look at the archipelago of Svalbard in the Arctic Circle and tries to unlock exactly how life can exist in such a cold, dark place. He discovers that the whole ecosystem is driven by the primary producers at the bottom of the food chain. Part of the "Nature's Microworlds" series.
Part of the "Branches on the Tree of Life" series. The term "algae" is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates, red algae (plastids with chlorophyll A), diatoms, yellow-brown algae and brown algae (chlorophylls A and C), and green algae (chlorophylls A and B). Explores the diversity, structure, ecological roles, and modern classification of these primary producers.
Photosynthesis converts light energy from the sun into chemical energy stored in organic compounds, which are used to build the cells of producers and ultimately fuel ecosystems. After providing an overview of photosynthesis, a series of animations describe the inside of the cells of a leaf to explain how the reactions of photosynthesis happen.
Without plants, perhaps the most important producers in the food chain, the world as we know it would not exist. Like all livings things, plants go through a series of life processes, the most important being reproduction and adaptation. How can plants grow everywhere? How does a species spread itself over great distances and into a variety of habitats? Investigates the characteristics and diversity of the ingenious solutions flowering plants, including fruit plants, have devised for propagation.
In January 2014, host Emily Graslie accompanied Bruce Patterson, Curator of Mammals, on a field expedition into the bat caves of Kenya. They were joined by media producers Greg Mercer and Emily Ward to document the experience. In this first installment, the team of researchers prepares to journey to Mt. Suswa. They have to travel deep into the cave before they encounter any bats. Part of "The Brain Scoop" series.
Leaf cutter ants could be called the overachievers of the insect world. They are farmers, medicine makers, and green energy producers. With support from the National Science Foundation, bacteriologist Cameron Currie studies the complex evolutionary relationships between the ants, the fungi they cultivate and eat, and the bacteria that influence this symbiosis. At the University of Wisconsin-Madison, Currie works with the Great Lakes Bioenergy Research Center on campus to explore how the ants manage to degrade cellulose. Her goal is to discover new ways humans might break down biomass into biofuels. The bacteria component of the ant colony could also help scientists develop more effective antibiotics for human health and agriculture.
