| July: Biosphere Reserve A part of an international network of preserved areas designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO). Biosphere Reserves are vital centers of biodiversity where research and monitoring activities are conducted, with the participation of local communities, to protect and preserve healthy natural systems threatened by development. The global system currently includes 324 reserves in 83 countries. |
| June: Rhizosphere Biodegradation A process associated with phytoremediation (the use of plants to reduce contamination) that causes biodegradation of contaminants near roots where compounds exuded by the root increase microbial biodegradation activity. Other plant processes such as water uptake can prevent migration by drawing contaminants to the roots. |
| May: Brownfields Abandoned, idled, or under-utilized industrial or commercial facilities where expansion or redevelopment is complicated by real or perceived environmental contamination. |
| April: Cryptosporidium A protozoan (single-celled organism) that can infect humans, usually as a result of exposure to contaminated drinking water. Many species of Cryptosporidium exist that infect humans and a wide range of animals. The parasite is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it very resistant to chlorine disinfection. |
| March: Double Hulled Tankers Large transport ships with two hulls with space between them, protecting the cargo (in most cases, oil) from spilling in case of a collision. |
| February: Bycatch Reduction Device (BRD): A device used to cut bycatch while fishing. These gear modifications are most commonly used with shrimp trawls. They are also called "finfish excluder devices" (FEDs) or, when specifically designed to exclude sea turtles, they are called "turtle excluder devices" (TEDs). |
