...problem is that biofuels are treated as if they were 100% carbon neutral, even though they are clearly not. When ethanol is burned, for instance, it still releases CO2 into the atmosphere. After all, the plants that go to make biofuels are made of carbon, just as oil and other fossil fuels are. Further, the use of biofuels would reduce total greenhouse-gas emissions only if their creation were to increase - or at least not displace - existing plant growth, which naturally takes carbon out of the atmosphere. For example, if the wood chips left over from logging were used...
Over the past five years, researcher David E. Boufford and others affiliated with the Harvard University Herbaria—an extensive collection of pressed, dried plant specimens housed at a Divinity Avenue facility—have been working to collect specimens of plant life in the remote mountain range on the Tibetan Plateau...
...International as one of the 34 “hotspots” of biodiversity in the world. According to Boufford, these hotspots only occupy 2.5 percent of the globe’s surface yet account for 35 to 40 percent of the variety in the world’s plant species...
...development of the lightbulb sparked the spread of electric power in the U.S. Edison was behind the creation of the first commercial power plant in 1882; New York City had electricity 10 years later. By the late 1930s, the Rural Electrification Administration, one of President Franklin D. Roosevelt's New Deal programs, had delivered electric lighting to nearly every corner of the country. Development on the bulb didn't stop either: researchers have modified Edison and Swan's design further, refining the filament by using tungsten and filling the vacuum with gas, both of which increase the life span...
Nonetheless, as I returned for sophomore fall, one big question mark remained: my academic future. It was already time to pick a concentration, and it didn’t seem like Harvard offered one for me. I knew I wanted to study environmental issues—but not geology, plant biology, or the chemistry of the stratosphere. Rather, the questions that intrigued me were social and political, not scientific. I wanted to figure out how humanity’s philosophies, cultures, and political structures interact with the natural environment...
