People should " like" KIA as much as they could.

What KIA motors has done is a sickening and disgusting kind of blackmailing people. And it's unacceptable cheapening for the value of human life.
Where are the ethical and moral obligations?
If I dislike your page on Facebook, would you then hungering people?

the answer is very clear: KIA
is effectively soliciting "likes" in exchange for putting food into the mouths of the under-nourished and the oppressed in Africa.

How we should face Kia's promotion? That is very basic. We should make likes as much as we could. "yes"
This would force KIA motors to actually come up with the money in the spirit of charitableness to world vision

A vulture is waiting for this African child to die of hunger!
