Kelp forests can be seen along much of the West Coast of North America. NOAA scientists study kelp forests by visiting the same locations over and over to assess the presence and abundance of a variety of organisms. Monitoring allows marine scientists to determine if the kelp forest is changing over time and to identify the cause of those changes, whether natural or human. Healthy kelp forests maintain the existence of thousands of plants, animals, and fish stocks. All of these require a thriving ocean ecosystem.

Researchers must be aware of three key areas when conducting psychological research: ethics, socially sensitive research, and ethnocentrism. All research must follow ethical guidelines; however, there may be reasons for breaching those guidelines. Viewers will explore how to address research justification and the use of knowledge and interpretation of findings in a socially sensitive research proposal. They will also note how to be aware of social construction and possible ethnocentric biases.
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.
Scientific evidence may show that human activity, particularly over the past 100 years, has led to a buildup of what are known as "greenhouse gases," the most common of which is carbon dioxide, in the atmosphere. Energy use, particularly the burning of fossil fuels and the large-scale removal of vegetation from the earth's surface, are thought to be largely responsible for greenhouse gas buildup.
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.
Under Prospecta Colombia 2012, an event organized by the Universidad Nacional Abierta y a Distancia, issues were raised and discussed related to the growth and development of cities. Nerdo Cavernas talks with the most prominent speakers present at this important event.
Environmental and science experts explore the enormous potential for clean, renewable energy. They also illustrate the connections among such issues as solar energy, wind energy, energy efficiency, green buildings, and global climate change. Viewers also learn specific action steps that viewers can take in their own lives to create a sustainable future.
Examines the impact of emerging technologies on the innovation process by showing a range of examples. Explores the meaning of innovation and emerging technology, the innovation cycle, and what makes an innovation successful. A case study of an innovation demonstrates the innovation process. Ends with a discussion of the impacts of innovation on society, including a strong emphasis on ethical and environmental issues.
The Three Gorges Dam is the largest hydro-electric dam in the world. Yet questions abound over environmental and social issues, not to mention the logistic problems of moving ships up and down the river. An ingenious system of ship locks has gone towards solving that problem, echoing the techniques of Banaue farmers in the Philippines who mastered the art of managing water over two thousand years ago.
Residents of Flint, Michigan describe their personal struggles with medical issues which arose from contaminated water. Lead from aging lines leached into the local water supply, along with bacteria and other contaminants, creating a serious health crisis. This documentary highlights the stories of residents who were personally injured, along with the work of local organizations and individuals that rallied to support them.
Service learning is much more than community service. It can influence a student's life in a substantial way and maybe even change the world. Students from four different schools in three different locations learn about local environmental issues and commit to making a difference in their community. Some of the projects include collecting data at an artificial reef, restoring native trees in the wetlands of Florida, repopulating ancient oyster beds, and cleaning up water ways.
Atterwasch is a small village in Germany and is slated for demolition. It's a casualty of Germany's Energiewende, the most ambitious transformation of a country's energy sector ever attempted. Germany's plan to shut down all their nuclear reactors has had other unintended consequences as well, most notably increased burning of brown coal, the direct cause of Atterwasch's plight. Scholar Johan Norberg explores the Energiewende, along with other world energy issues like ethanol and fracking, both of which have also had consequences not anticipated.
The estuary is part of the Plum Island Ecosystems LTER (Long Term Ecological Research). The LTER Network was created by the National Science Foundation (NSF) in 1980 to conduct research on ecological issues that can last decades and span huge geographical areas. Biogeochemist Anne Giblin, of the Marine Biological Laboratory, is leading a team of researchers who are studying the Plum Island salt marshes to determine how this 2,000-year-old ecosystem is holding up under climate change, land use changes, and sea-level rise.

The Pajaro Valley, in the Monterey Bay area of California, is ideally suited for agriculture. In fact, the Pajaro Valley and the nearby Salinas Valley produce nearly half of the strawberries grown in the United States yearly. But, the water source for the valley is a confined underground aquifer that is slowly being depleted. In January of 2011, the American Institute of Mathematics held a Sustainability Problems workshop with the goal of bringing together mathematicians and industry representatives to work on a variety of sustainability problems, including renewable energy, air quality, water management, and other environmental issues. Part of the National Science Foundation Series “Science Nation.”
Human actions can have positive and negative impacts on Earth. Students will learn ways to make sure they help preserve the Earth.
Students will learn practices for keeping the Earth healthy. The video distinguishes between unstainable and sustainable practices.
What is biodiversity? Students explore the concept of biodiversity as it applies to a wide range of ecosystems on Earth.
Scientists and researchers are working to understand the possible effects of Antarctic ice melt on global processes. Some areas that might be impacted include currents, water chemistry, and biological balance.
Shifting sands filling up shipping lanes are a fact of life on the North Carolina coast. Scientists are looking at new ways to manage dredged materials and protect the environment.
In this episode, Joel learns how homeowners can keep their yards environmentally friendly. Part of the Curiosity Quest Series.
