ENVIRONMENT - February 2016

World's Biggest Bee Found Alive

  •  The world's biggest bee has been re-discovered, after decades thought lost to science.
  • The giant bee - which is as long as an adult's thumb - was found on a little-explored Indonesian island.
  • Known as Wallace's giant bee, the insect is named after the British naturalist and explorer Alfred Russel Wallace, who described it in 1858.

Giant Tortoise Believed Extinct for 100 Years Found

  •  A living member of species of tortoise not seen in more than 110 years and feared to be extinct has been found in a remote part of the Galápagos island of Fernandina.
  • An adult female Chelonoidis phantasticus, also known as the Fernandina giant tortoise, was spotted by a joint expedition of the Galápagos National Park and the US-based Galapagos Conservancy.
  • Investigators think there may be more members of the species on the island because of tracks and faeces they found.
  • The International Union for Conservation of Nature has the Fernandina giant tortoise listed as critically endangered and possibly extinct.

Industries Fined for Toxic Effluents in Drains

  •  In its first-ever drive against illegal discharge of industrial waste, the Delhi State Industrial and Infrastructure Development Corporation Ltd. (DSIIDC) has fined 910 industries for directly releasing toxic effluents into drains.
  • The action is part of a survey that is currently under way in Delhi to identify the number of industries that are still not linked to a common effluent treatment plant (CETP), despite rules asking them to do so.
  • It is a first that an agency has started to map industries and their linkages to CETPs in Delhi. The DSIIDC said that until February 15, it inspected 7,794 units out of which show-cause notices have been issued to 956 for effluent release violations.

First Aquatic Census

  •  A first of its kind census conducted by experts from Zoological Survey of India (ZSI), Wildlife Trust of India (WTI) and Tilka Majhi University, Bhagalpur has found out that there are only 1150 dolphins in different rivers of Bihar.
  • Since such an extensive census hasn't been conducted in the past, it cannot be verified whether the number of the mammals has increased or decreased in the recent past in the rivers of Bihar.
  • The recent census, which is the first ever aquatic census of dolphins in Bihar by the direct count method, was done in the Ganges, Gandak and Ghaghara, which are home to the Ganges River Dolphins.

The World's Oceans to Change Colour

  •  The world's oceans are warming and growing more acidic as a result of climate change, and a provocative new study suggests they'll be changing color too.
  • Within a few decades regions of the ocean that now look blue will look bluer. By 2100, the colour shift could affect more than 50 per cent of the oceans' collective 140 million square miles of surface area.
  • But it's not the colour of the water itself that will change. Rather, it's that populations of marine phytoplankton will fall as seawater warms.
  • Since these tiny organisms contain the green pigment chlorophyll, any change in their numbers affects the water's apparent colour.
