While everyone has probably heard the term “nuclear energy” and likely made jokes about it involving extra fingers, glowing skin, or Homer Simpson, knowing what it actually is and what it does is far less common. As far as human participation goes, nuclear energy has been around since the beginning of World War II, when several countries started looking...
Hydroelectric power, or hydropower, refers to using moving water to generate electricity. Water flowing downhill turns turbines that drive electric generators. Reservoirs created by dams allow operators to precisely control the rate of water flow and the amount of power produced. A release pipe called a penstock concentrates the force of the elevated water in the reservoir. As long...
Fossil fuels have been the primary source of energy for human civilization since the start of the industrial revolution. While coal, oil and natural gas still supply most of the world’s energy, growing concerns about dwindling supplies and the carbon released when these fuels are burned have spurred a search for clean, renewable energy sources. While wind and solar...
Plasma energy is produced when fusion takes place in a controlled and magnetized environment. Plasma is the fourth state of matter, a gas in which a sufficient amount of energy is present to enable ions and electrons to coexist. Scientific evidence suggests that plasma is actually the most common state of matter in the universe, and plasmas are even...
Starting in the 18th century and gaining popularity in the 19th century, the Industrial Revolution brought about drastic changes in the social and economic lives of humans. The benefits of the revolution are felt even today, but so are the adverse effects. The introduction of industrialization brought about industrial pollution. During the revolution, technology, manufacturing, and science all began rapidly...
Green technology combines science and technology to reach a goal of repairing the world’s ecosystems. Also known as environmental or clean technology, this strategy encompasses a wide variety of techniques, such as green building, recycling and using clean energy. The ultimate goal is to conserve nature and make the Earth a sustainable place for future generations. We’re digging into...
In today’s world, there seems to be a growing focus on practices that are sustainable and respectful of the environment.  This includes turning to forms renewable energy as alternatives to fossil fuels. One of the most well-known and visible examples of a sustainable energy source is wind power. If you’ve ever been on a road trip and seen fields...
The grassland is home to majestic creatures that many in the western world can only hope to see in a zoo. Animals like elephants, cheetahs, and lions thrive in the grassland environment, but the biome is at increased risk as human development continues to expand.The grassland ecosystem is diverse but fragile. Since the climate is so dry, a few...
world map of changes in forest area
Below: Map indicating the the net changes in forest area 2000-2005 (note that all the areas in red - decrease of more than 50% - are in the tropics and the majority of the loss are prime habitat for primates. Taken form the FAO 2005 publication: Global Forest Resources Assessment 2005; Progress towards sustainable forest management
Global temperature
The thermohaline circulation is a global ocean circulation. It is driven by differences in the density of the sea water which is controlled by temperature and salinity (Broecker, 1995). The thermohaline circulation is sometimes called the “ocean conveyor belt” and plays an important role in supplying heat to the polar regions. There are projections that global warming could shut...
