One fine day, a large coal power plant being owned by one of TGD Inc's subsidiaries witnesses about a hundred activists vociferously protesting against it, demanding that the group CEO Karbon Kapucha take immediate steps to stop generating power using coal.

Given that Karbon is considered one of the world's most climate conscious CEOs, the activists are even more livid that his company still operated a coal power plant!

Karbon personally visits the scene of the agitation and tries to reason with the activists. He tells them that his company will gradually shut down coal power plants, and tries to impress upon them that it could not however be done right away, but his considered appeals are to no avail.

Karbon reaches his office, a distraught man. He was torn between the idealism of the protestors and the impracticality of shutting down a coal plant. But something had to be done.

It was then that he remembered his mother's words of wisdom fed to him while he was playing on her lap as a small child, "Karbon, remember, you sometimes need a thorn to remove a thorn".

Even his fertile mind could not recollect what un-ordinary circumstances had impelled a motherly soul to talk about thorny issues to a child toddling on her lap, but such familial recollections could wait. More importantly, the amazing power of the core philosophy dawned on Karbon - a thorn for a thorn. Mom, he murmured fervently, you have once again shown your dear child the light of wisdom.

It was nearing midnight, but he pronto buzzed the head of the coal power plant and asked him to shut down the coal power plant.

The head was shocked to his marrows. "Mr Kapucha, are you serious? We cannot do this. The whole city will go without power. Civilization will cease to exist for almost a million people."

"My friend," said Karbon, "That is the whole point. And trust me, this won't be for long."

The head did as he was ordered with grave forebodings, but his apprehensions were short-lived, just as Karbon had prophesied. 

By 4 AM the next day, over hundred thousand people had gathered in front of the power plant demanding that the power plant start generating power from coal.
