This class explores the interrelationship between humans and natural environments. It does so by focusing on conflict over access to and use of the environment as well as ideas about "nature†in various parts of the world.
Modern industrial activities - which MIT engineers and scientists play a major role in - have significant environmental and social impacts. Trends towards further industrialization and globalization portend major challenges for society to manage the adverse impacts of our urban and industrial activities. How serious are current environmental and social problems? Why should we care about them? How are governments, corporations, activists, and ordinary citizens responding to these problems.
This course examines environmental and social impacts of industrial society and policy responses. We will explore current trends in industrialization, urbanization, and globalization, analyze the impacts these trends have on human health, environmental sustainability, and equity, and then examine a range of policy options available for responding to current problems. The course will present key trends in both domestic and international contexts.
We will examine four policy problems in particular during the course: (1) regulating industrial pollution; (2) regulating "sweatshops" and the broader impacts of globalization; (3) protecting ecosystems; and (4) protecting urban environments during development. We delve into specific cases of these challenges, including: chemical safety and toxins; computers, e-commerce, and the environment; biotech and society; sweatshops; and food production and consumption. Through these cases, we will explore underlying processes and drivers of environmental degradation. Finally, we will analyze opportunities and barriers to policy responses taken by governments, international institutions, corporations, non-governmental organizations, consumers, and impacted communities.

A great variety of processes affect the surface of the Earth. Topics to be covered are production and movement of surficial materials; soils and soil erosion; precipitation; streams and lakes; groundwater flow; glaciers and their deposits. The course combines aspects of geology, climatology, hydrology, and soil science to present a coherent introduction to the surface of the Earth, with emphasis on both fundamental concepts and practical applications, as a basis for understanding and intelligent management of the Earth's physical and chemical environment.
Student teams formulate and complete space/earth/ocean exploration-based design projects with weekly milestones. This course introduces core engineering themes, principles, and modes of thinking, and includes exercises in written and oral communication and team building. Specialized learning modules enable teams to focus on the knowledge required to complete their projects, such as machine elements, electronics, design process, visualization and communication. Examples of projects include surveying a lake for millfoil from a remote controlled aircraft, then sending out robotic harvesters to clear the invasive growth; and exploration to search for the evidence of life on a moon of Jupiter, with scientists participating through teleoperation and supervisory control of robots.
This design-based subject provides a first course in energy and thermo-sciences with applications to sustainable energy-efficient architecture and building technology. No previous experience with subject matter is assumed. After taking this subject, students will understand introductory thermodynamics and heat transfer, know the leading order factors in building energy use, and have creatively employed their understanding of energy fundamentals and knowledge of building energy use in innovative building design projects. This year, the focus will be on design projects that will complement the new NSTAR/MIT campus efficiency program.
This course examines diagnostic studies of the Earth's atmosphere and discusses their implications for the theory of the structure and general circulation of the Earth's atmosphere. It includes some discussion of the validation and use of general circulation models as atmospheric analogs.
For the first time in history, the global demand for freshwater is overtaking its supply in many parts of the world. The U.N. predicts that by 2025, more than half of the countries in the world will be experiencing water stress or outright shortages. Lack of water can cause disease, food shortages, starvation, migrations, political conflict, and even lead to war. Models of cooperation, both historic and contemporary, show the way forward. The first half of the course details the multiple facets of the water crisis. Topics include water systems, water transfers, dams, pollution, climate change, scarcity, water conflict/cooperation, food security, and agriculture. The second half of the course describes innovative solutions: Adaptive technologies and adaptation through policy, planning, management, economic tools, and finally, human behaviors required to preserve this precious and imperiled resource. Several field trips to water/wastewater/biosolids reuse and water-energy sites will help us to better comprehend both local and international challenges and solutions.
Students are introduced to innovative stormwater management strategies that are being used to restore the hydrology and water quality of urbanized areas to pre-development conditions. Collectively called green infrastructure (GI) and low-impact development (LID) technologies, they include green roofs and vegetative walls, bioretention or rain gardens, bioswales, planter boxes, permeable pavement, urban tree canopy, rainwater harvesting, downspout disconnection, green streets and alleys, and green parking. These approaches differ from the traditional centralized stormwater collection system with the idea of handling stormwater at its sources, resulting in many environmental, economic and societal benefits. A PowerPoint® presentation provides photographic examples, and a companion file gives students the opportunity to sketch in their ideas for using the technologies to make improvements to 10 real-world design scenarios.
Students discover how tiny microscopic plants can remove nutrients from polluted water. They also learn how to engineer a system to remove pollutants faster and faster by changing the environment for the algae.
Students are presented with a guide to rain garden construction in an activity that culminates the unit and pulls together what they have learned and prepared in materials during the three previous associated activities. They learn about the four vertical zones that make up a typical rain garden with the purpose to cultivate natural infiltration of stormwater. Student groups create personal rain gardens planted with native species that can be installed on the school campus, within the surrounding community, or at students' homes to provide a green infrastructure and low-impact development technology solution for areas with poor drainage that often flood during storm events.
This lesson plan helps students understand the factors that affect water quality and the conditions that allow for different animals and plants to survive. Students will look at the effects of water quality on various water-related activities and describe water as an environmental, economic and social resource. The students will also learn how engineers use water quality information to make decisions about stream modifications.
Students learn about porosity and permeability and relate these concepts to groundwater flow. They use simple materials to conduct a porosity experiment and use the data to understand how environmental engineers decide on the placement and treatment of a drinking water well.
Students learn about the human water cycle, or how humans impact the water cycle by settling down in civilizations. Specifically, they learn how people obtain, use and dispose of water. Students also learn about shortages of treated, clean and safe water and learn about ways that engineers address this issue through water conservation and graywater recycling.
This unit is geared for high school biology students. The unit will take place after the students have learned about ecology and population growth. The students will use their prior knowledge on subjects like food webs and balance within ecosystems to understand how small factors can cause great changes.
The unit will start off by considering invasive species and how the introduction of a single new organism into an ecosystem that is already in balance can disrupt the flow of energy. With this in mind, the students will think about how humans have done something similar. We introduced ourselves into new areas and have caused environmental harm. From there, we will study climate-based damage caused by humans and consider the environmental and biological impacts.
Finally, we will design strategies to adapt to a changing planet. This will have the students looking into how the world has changed, and what we can do to cope with the diverse climate-based impacts.
Earl Ubell is a pioneer among science and health writers in America. After a long, distinguished career at The New York Herald Tribune from 1943 to 1966, he went on to work at both CBS and NBC News. Prominent in the emerging scientific writing community in the 1950s and early 1960s, he was a recipient of the Lasker Medical Journalism Award 1957. Milton Stanley Livingston was a leading physicist in the field of magnetic resonance accelerators. Working first with professor Ernest O. Lawrence at the University of California, Livingston was instrumental in the development of the Berkeley cyclotron. Moving to Cornell in 1938, Livingston was part of the core group who established nuclear physics as a field of study. Choosing to stay with the Cornell cyclotron rather than follow colleagues onto the Manhattan Project, Livingston was involved in the production of radioisotopes for medical purposes. At the time of this interview, Livingston was director of the Cambridge Electron Accelerator, a joint project of Harvard University and MIT.In this program segment Louis Lyons quizzes Earl Ubell about the lack of public knowledge and the perception of the nuclear bomb, while pressing Professor Livingston to explain exactly what nuclear fallout is, and the danger it presents.
Through an overview of some of the environmental challenges facing the growing and evolving country of China today, students learn about the effects of indoor and outdoor air pollution that China is struggling to curb with the help of engineers and scientists. This includes the sources of particulate matter 2.5 and carbon dioxide, and air pollution impacts on the health of people and the environment.
Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on air and land quality issues. Air quality topics include air pollution sources, results of poor air quality including global warming, acid rain and air pollution, as well as ways to reduce air pollution. Land quality topics include the differences between renewable and non-renewable resources, the results of non-renewable resource misuse and ways to reduce land pollution. (Water quality is introduced in a later lesson in a separate presentation, as it is the focal point of this unit curriculum.)
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"A new control design could help engineers improve the stability and optimality of long, slender beams, including those used for offshore engineering. Numerous important dynamical systems are governed by nonlinear partial differential equations: from chemical reactions to epidemics to engineering structures. While optimal control designs have been attempted for these highly complex systems, doing so is extremely difficult. The inverse control approach has proven useful for extending optimal designs from linear to nonlinear systems but, for the most part, only for Euclidean spaces. Extension to Hilbert spaces faces difficulties due to infinite-dimension and the formidable obstacle of having to solve a Hamilton–Jacobi–Bellman equation. Now, researchers have found a way to surmount that barrier, formulating a control design that can be used to reliably stabilize extensible and shearable beams..."

Clean and purified drinking water is a basic human need and over ¾ of the Earth’s human population has the luxury of having it piped directly into their homes. Unfortunately, that leaves almost 2 billion people worldwide where access to clean water is questionable. This unit will help students understand the risks involved with drinking untreated water and engage them in an engineering project to produce a means of filtering water to make it less risky. The beginning of this unit is designed to first help students understand the risks of drinking dirty water by introducing them to the world of microbial pathogens. Students will learn about some of the most common bacteria, viruses, and protozoa that can be lurking in a potential drinking water source. Then students will learn the basics of water treatment and how water treatment has evolved over the past thousand years. Students will use this knowledge to finally construct and test a water filter of their own design.
The unit was written in partnership with Dr. Jordan Peccia, a professor of Environmental Engineering at Yale University. It is designed for elementary students as young as third grade, but the concept and strategies involved can easily be adapted to learners of any age.
Through multi-trial experiments, students are able to see and measure something that is otherwise invisible to them seeing plants breathe. Student groups are given two small plants of native species and materials to enclose them after watering with colored water. After being enclosed for 5, 10 and 15 minutes, teams collect and measure the condensed water from the plants' "breathing," and then calculate the rates at which the plants breathe. A plant's breath is known as transpiration, which is the flow of water from the ground where it is taken up by roots (plant uptake) and then lost through the leaves. Students plot volume/time data for three different native plant species, determine and compare their transpiration rates to see which had the highest reaction rate and consider how a plant's unique characteristics (leaf surface area, transpiration rate) might figure into engineers' designs for neighborhood stormwater management plans.
