 Have you wondered why politicians aren't what they used to be, why governments seem unable to solve real problems? Economist Yanis Varoufakis, the former Minister of Finance for Greece, says that it's because you can be in politics today but not be in power -- because real power now belongs to those who control the economy.

Melati and Isabel Wijsen are on a mission to stop plastic bags from suffocating their beautiful island home of Bali. "Don't ever let anyone tell you that you're too young or you won't understand," Isabel says to other aspiring activists. "We're not telling you it's going to be easy. We're telling you it's going to be worth it." Watch » | |
