It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions. ~Mark Twain

The human spirit is not dead.  It lives on in secret.... It has come to believe that compassion, in which all ethics must take root, can only attain its full breadth and depth if it embraces all living creatures and does not limit itself to mankind.  ~Albert Schweitzer

Animals can communicate quite well.  And they do.  And generally speaking, they are ignored.  ~Alice Walker
When a man wants to murder a tiger he calls it sport; when the tiger wants to murder him he calls it ferocity. 
 ~George Bernard Shaw
Mankind has always been cruel to all other creatures on earth, atleast most of mankind! Being unable to go and actually do something, for now, I have resorted to just capturing their essence on paper. I hope to do something more soon.
