Describes human activities' effects on earth. Examines how humans, industrialization, and technologies impact the environment, water cycle, and land use. Encourages better planning and management of resources.
Environmental scientist Tamar Losleben explains how environmental engineers research and plan the best ways to use resources to satisfy both human and environmental needs.
Biodiversity is crucial to sustaining life on Earth, and students learn about the efforts being made by scientists all over the world to maintain it.
Part of the "Green Careers" series. Examines how staffers at nonprofit agencies work with lawyers, lobbyists, and other concerned citizens to advocate for environmental protection and strategies for sustainable growth. Jobs profiled include the following: environmental attorney, research associate, press secretary, community organizer, and attorney.
Students explore the important role the environment plays in everyday life. Several environmental problems are highlighted, with a focus on pollution and global warming. Additional concepts and terminology discussed include ecology, biological extinction, resource depletion, overconsumption of resources, fossil fuels, global climate change, and natural resources.
Amy Pickering is an environmental health engineer and works as a research associate at Stanford University. Environmental engineers are biological and agricultural engineers who specialize in the environment and its affect on health. Part of the "Career Spotlight" series.
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.
An environmental scientist who provides clean water to the city of Philadelphia explains how this water is used in homes, parks, and swimming pools and to fight fires. Shows that river water from rain and farm runoff is dirty and needs to be purified before people can use it. Visits the Fairmount Water Works and explains how water is brought to such plants, purified, and sent on to homes and factories. Also, emphasizes why caring about the health and safety of rivers are important.
Whether they arise from human causes or forces within planet Earth itself, natural disasters threaten life and civilization with what seems to be growing frequency. Studies troubling developments in marine, arctic, wetland, and urban environments while highlighting research opportunities that may help prevent future catastrophes. Coral reef decay, Everglades habitat loss, polar ice disappearance, and global warming are all analyzed. Looks at earthquake prediction, hurricane and tornado tracking, air pollution monitoring, tsunami warning systems, and the cleanup of toxic flood sediment in New Orleans.
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.
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.
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.
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.”
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.
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.
In this episode, Joel learns how homeowners can keep their yards environmentally friendly. Part of the Curiosity Quest Series.
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.
Paper is used for many things which can lead to excessive waste. New environmental programs focus on decreasing the consumption of usage as well as the benefits of recycling.
