A federally funded scientific study on regional seagrass health recently released by The Nature Conservancy points to nitrogen pollution — from sewage and fertilizers — and warmer water temperatures as the killer threats to seagrasses throughout the coastal waters of southern New England.
Seagrass is vital habitat for fish and shellfish and is important for water quality.

Como parte del Plan de Acción Climática de la Presidencia de EEUU, "Estrategia para Reducir las Emisiones de Metano", la Agencia de Protección Ambiental de EE.UU. (EPA) propone cambios a las normas de aire para nuevos residuos sólidos urbanos (RSU) en confinamientos. Estos cambios requerirÃan ciertos confinamientos adicionales para capturar los gases de los confinamientos originales, lo que reducirÃa las emisiones de metano, un potente gas de efecto invernadero, y ayudar a reducir aún más la contaminación que daña la salud pública.

A study by the British Geological Survey and the Environment Agency reveals that almost all the the oil and gas bearing shales in England and Wales underlie drinking water aquifers, raising fears that widespread water contamination could occur. The British Geological Survey (BGS) in partnership with The Environment Agency (EA) have published a map which show the depth to each shale gas and oil source rock below principal groundwater aquifers in England and Wales.

Baleen and sperm whales, known collectively as the great whales, include the largest animals in the history of life on Earth. Though large in size, whales have long been considered too rare to make much of a difference in the ocean, and the focus of much marine ecological research has been on smaller organisms, such as algae and planktonic animals. While these small organisms are essential to life in the sea, they are not the whole story. As great whales recover from centuries of overhunting, scientists are beginning to appreciate their roles as ecosystem engineers of the ocean.
