Have a look at this site-
It works better on Google Chrome ...If u have it then you can access to the site. And your 2nd question -"What is that?" It is a scary site which tells you about the consequences of human devastating development.Basically it is a replica of -How will our Earth will look when there will be water rise in all the continents of our world, after 100 years.. Through this post I would like to convey a message that-Earth is the thing which is sustaining our existence. So,be smart & help each other to escape from the deadly end! 22nd of may is Biodiversity Day & 5th of May is Environment Day...So ,plant a life !
