Notes from around the World.

According to Global Forest Watch, 16 million hectares of tropical forests have  disappeared in 2017 alone.   Anthropogenic activities are the major  causes  for this green cover loss.    For example  take the case of Colombia.  Situated in  the north western corner of the South American continent, Colombia  ranks high among megadiverse countries. According to the Convention on Biological Diversity website,   Colombia  ranks first in bird and orchid species' diversity and second in plants, butterflies, freshwater fishes and amphibians. With 314 types of ecosystems, Colombia possesses a rich complexity of ecological, climatic, biological and ecosystem components.  Colombian   President recently asserted that biodiversity is to Colombia what oil is for the Arab countries.

But ever since the  ultraleft guerrillas, the FARC, (Revolutionary Armed Forces of Colombia), signed the  peace treaty with the Colombian govt.  and vacated the valleys and  forests (which were their habitat for 50+ years) Colombia's  ecological wealth has been fast disappearing. Because  urban developers want to clear the forests to set up housing, industrial and commercial projects and  of course  timber is  a source of easy money.

An equally disturbing   situation is unfolding in Antarctica . The Antarctica Treaty was initiated  in 1959 with 12 nations.  Later this number grew to  53. According to the Environmental Protocol the participating countries committed themselves to protect and cherish the ecosystem and use it only for science and peace.  All the  signatories  were on the same page while signing, but no longer so. Geopolitics is threatening the pristine continent because of  speculations on  the continent's stock of fish and  minerals as every nation wants a share.   Recent reports state  that in  Ile aux Cochons, an Antarctica island,  penguin population has declined by 90% in a span of 3 decades for reasons as yet unknown.   
               Deepwater Horizon Disaster

Meanwhile the United States has  relaxed its Ocean Policy.  Earlier  administration had put stringent restrictions on offshore activities  after the 2010 Deepwater Horizon  Disaster  in the gulf of Mexico.   That disaster,  an explosion  in the deep sea  oil rig, caused  134 million gallons of crude oil to spew out into the Gulf of Mexico causing environmental damages to the tune of   17.2 billion dollars. This damage has not yet been contained nevertheless   US Govt. has decided to revoke the restrictions and   promote offshore drilling for gas and oil  over approximately 78 million acres offshore. The region-wide lease sale  is scheduled for Aug. 15, 2018. 

We were just 1 billion people in the year 1800 and currently  register 7.6 billion and by 2100 the number will touch 11 billion.  Population challenge is compounded  by shrinking villages and booming urban spaces. 70% of the global population will be city dwellers by 2050.   China, India and Nigeria are expected to lead in this sphere.  Sure enough  anthropogenic activities associated with urbanisation will steadily and rapidly deplete natural resources.  Who should be concerned, Man or Mother Nature?  Nature has been through 5 cataclysmic mass extinctions, it can easily survive one more. Professor Reinhard Huttl at the Helmholtz Institute for Earth and Environment  observes wryly that Earth has enough  generative power to tide over  any disaster, it is us humans who are in danger.
