The cause is almost entirely "human activities" after the industrial revolution . What are these human activities? Who carried out the industrial revolution? What type of economic system which is responsible for it? Are global corportaions, in collusion with governments, looking for higher profits responsible? Or, is it smoking cigarettes, farting, barbecuing, etc responsible? Impartiality of the BBC!
“The West won the world not by the superiority of its ideas or values or religion (to which few members of other civilizations were converted) but rather by its superiority in applying organized violence. Westerners often forget this fact; non-Westerners never do.” —Samuel P. Huntington, The Clash of Civilisation and the Remaking of the World Order, 1996, p. 51
