Pollution is waste material produced from human activities. It impacts the environment in a negative way. Explores how pollution can affect the air, water, and land in the form of gases, liquids, and solids. Substances that constitute pollution in the environment include: greenhouse gases (CO2, smog, and industrial emissions), oil, blue/green algae, plastic, litter, dog poop, and fertilizer. Also explores how a sustainable future depends upon individuals and society minimizing pollution by making informed and responsible decisions when choosing consumer items.
For centuries, land travel was restricted to how fast and far humans or animals could walk. In the 19th century, the invention of the bicycle transferred human energy to a set of wheels. During the Industrial Revolution, the invention of the steam engine led to the railroad, a change in transportation that created the tourist industry. In the early 20th century, the invention of the automobile forever changed how humans travel, and with the assembly line, Henry Ford forever changed how goods are manufactured.
Many of our daily activities generate carbon dioxide and contribute to global warming and climatic changes. While carbon dioxide and other greenhouse gases are necessary for our survival, some research indicates that an increase in their levels may alter the climate. The increased presence of these gases can magnify the natural greenhouse effect of the atmosphere and damage the environment. However, there are steps individuals can take to decrease the impact of global warming and climate change. Chapter 1 of Air: Climate Change Series.
In Colorado, drilling for oil and natural gas using hydraulic fracturing, sometimes referred to as fracking, is big business. But questions about its impact on the air and water are far from settled. With support from the National Science Foundation, University of Colorado environmental engineer Joseph Ryan heads a team gathering data on the pros and cons of oil and natural gas development, including the use of hydraulic fracturing.

Engineers are joining forces with designers, scientists, and doctors at Drexel University to produce new biomedical textiles, and the resulting smart clothes are not only fashionably functional, but could also be life savers. With support from the National Science Foundation (NSF), electrical and computer engineer Kapil Dandekar, industrial and fashion designer Genevieve Dion, and OB-GYN Owen Montgomery are incorporating RFID technology into their “belly bands” for women with high-risk pregnancies. The band continuously tracks data and alerts the doctor’s office via the Internet should the woman start contractions. Part of the National Science Foundation Series “Science Nation.”
How can honeybees communicate the locations of new food sources? Austrian biologist, Karl Von Frisch, devised an experiment to find out. By pairing the direction of the sun with the flow of gravity, honeybees are able to explain the distant locations of food by dancing. The scientists at Georgia Tech University explain the design of Von Frisch's famous experiment and describe the precise grammar of the honeybees dance language with new computer vision techniques. They hope the research into behaviors of social insects will aid in the design of better systems of autonomous robots.
In less than a second a sandfish lizard can dig its way into the sand and disappear. The sandfish's slithering moves are inspiring new robotic moves that could one day help search and rescue crews find survivors in piles of rubble left from disasters. With support from the National Science Foundation, physicist Daniel Goldman and his team at Georgia Tech are studying the lizard’s movements, using x-rays to track it underground. Their findings will contribute to engineering designs for deployable robots that could one day help canine search and rescue teams find survivors more quickly.
In the conquest of space today, it is robots, not humans, who get the glory. Describes missions that represent the foreseeable future in space exploration: sensor-filled craft and remotely operated devices going where people can't. The program features Deep Impact, a comet-blasting probe; Cassini-Huygens, pioneer of Saturn's moon, Titan; Robonaut, a machine designed to perform human tasks; Ranger, a huge mechanical spider that could conceivably repair the Hubble Space Telescope; the Hubble itself, aging but carrying on; and the planned Webb Space Telescope, Hubble's eventual successor on the vanguard of deep-space science.
Consider the following: humans live twice as long as their ancient ancestors did even though their bodies contain different types of synthetic and sometimes toxic substances. This is an unpleasant part of life in the modern age. Explores the health impact, wide variety, and alarming ubiquity of manufactured chemicals. Shows how communities around the world, including Inuit seal hunters, Asian and African farmers, and residents of an industrial town in the United States address the pervasiveness of molecular compounds found in pesticides, plastics, and other products. The benefits of these chemicals are weighed against their dangers.
Explains the science behind the workings of a nuclear power station. The basic version explores what fission is; the role of cooling water in nuclear reactors; the nuclear fuel cycle on mining, milling, enrichment, fabrication, and spent fuel on storage and reprocessing; and other uses of nuclear energy, including "non-power" uses. The advanced version expands on this information with a specific example of a fission reaction; the use of water to vary reactor power; different methods of mining uranium; a detailed discussion of enrichment, including structure and properties of uranium hexafluoride; and two methods of enrichment: centrifuging and gas diffusion.
Throughout the world, innovative thinkers and entrepreneurs are transforming their communities, making the dream of sustainable living a reality. The United Kingdom's push for sustainable housing developments raises awareness of energy efficiency and promotes eco-friendly home design. Cement alternatives developed in Australia reduce the carbon footprint for concrete production by 60%. Two industrial designers from Colombia are creating fashion items from recycled tires. In the Philippines, the inventor of coconut fiber nets shows how his company helps prevent devastating mudslides in the region and provides employment to locals.
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 discuss the treatment of animals in the industrialized food industry. Part of the Nourish Short Films Series.
Access to affordable, sustainable energy supplies is a growing concern around the world. Looks at successful enterprises that are providing some renewable energy solutions. In Scotland, small-scale turbines put wind power within the reach of domestic users. In Sweden, the world's first train to be run solely on biogas has been developed. In Nepal, biogas stoves are improving the quality of life in many ways. And in India, agricultural-plant waste is being turned into solid fuel briquettes for use in industrial stoves and boilers, while a solar-energy company has developed environmentally friendly lighting technology that disadvantaged communities can afford.
One of the major challenges in robotics is designing robots that can move over uneven, loose, or unexpected terrain. With support from the National Science Foundation, computer engineer Luther Palmer and his team at the Biomorphic Robotics Lab at the University of South Florida are designing computer simulation models for the next generation of robotic legs, and then building them in the lab. The team studies the biomechanics of animals adept at running on rough ground to program the algorithms that power their computer simulations.
