The Ecology and Environmental =>

The quantity of greenhouse gases in the atmosphere keeps increasing. The Earth's temperature is rising. Now media are reporting that we only have 18 months to save the climate. Scaremongering, or a serious prognosis?

This time, the warning came directly from Buckingham Palace in London. "I am firm of the view that the next 18 months will decide our ability to keep climate change to survivable levels and to restore nature to the equilibrium we need for our survival," -- Prince Charles said recently.

P.M. Modi: led for ‘One Sun One World One Grid’  (OSOWOG) Initiative.

“state of environmental emergency”: has been declared by the island nation of Mauritius. The environmental emergency has been declared as a Japanese bulk carrier “MV Wakashio” ran aground on a reef in Mauritius and began leaking oil into the ocean. The ship stranded two weeks ago(in July 2020) is leaking tons of fuel into the surrounding waters.

Digging in the past:--

 

·        ·        Bio-Diversity Hot-SpotH: areas where there is a high concentration of Endemic Species and is suffering from habitat loss or distortion. A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.

·        Anoxic Water: Anoxic waters are areas of seawater, freshwater, or groundwater that are depleted of dissolved oxygen. The US Geological Survey defines anoxic groundwater as those with a dissolved oxygen concentration of less than 0.5 milligrams per liter.

·        Hypoxia: It is the situation of Anoxic Water, having 0% concentration of Dissolved Oxygen.

·        Hypoxic or Dyoxic water: water is having a concentration of D.O. between 1% to 30%.

·        Exaerobic: when the area D.O. concentration lies between two.

·        Dead Zones: Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water. Currently there are some 400 dead zones worldwide.·

Biomagnification: This implies the concentration of Toxic in successive magnification by Toxic Compound that passes forth via Food Chain. Biomagnification, also known as bio-amplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain. 

It is all due to the excessive exploitation of resources that led to this devastating situation. Hence, To avoid it, we should adopt for 

Sustainable Development.
