There's no such thing as throwing something away, says Andrew Dent -- when you toss a used food container, broken toy or old pair of socks into the trash, those things inevitably end up in ever-growing landfills. But we can get smarter about the way we make, and remake, our products. Dent shares exciting examples of thrift -- the idea of using and reusing what you need so you don't have to purchase anything new -- as well as advances in material science, like electronics made of nanocellulose and enzymes that can help make plastic infinitely recyclable.

In the US, your taxes fund academic research at public universities. Why then do you need to pay expensive, for-profit journals for the results of that research? Erica Stone advocates for a new, open-access relationship between the public and scholars, making the case that academics should publish in more accessible media. "A functioning democracy requires that the public be well-educated and well-informed," Stone says. "Instead of research happening behind paywalls and bureaucracy, wouldn't it be better if it was unfolding right in front of us?"

There are about 7,000 languages spoken around the world -- and they all have different sounds, vocabularies and structures. But do they shape the way we think? Cognitive scientist Lera Boroditsky shares examples of language -- from an Aboriginal community in Australia that uses cardinal directions instead of left and right to the multiple words for blue in Russian -- that suggest the answer is a resounding yes. "The beauty of linguistic diversity is that it reveals to us just how ingenious and how flexible the human mind is," Boroditsky says. "Human minds have invented not one cognitive universe, but 7,000."

Ndidi Nwuneli has advice for Africans who believe in God -- and Africans who don't. To the religious, she advises against using God to outsource responsibility for what happens in their lives. To the non-religious, she asks that they keep an open mind and work with faith-based organizations, especially on issues like health care and education. "There's so much potential that can be realized when we walk across the divide of faith and, hand in hand, try to solve many of our problems," Nwuneli says.
