Beautiful, bizarre images of Earth taken by the European Space Agency’s fleet of Earth-observing satellites.

These pictures are more than just cool: In a talk at TEDxBarcelona, Stephen Briggs — head of Earth Observation science at the ESA’s European Space Research Institute — tells the fascinating tale behind the satellite and explains how these uncommon images of Earth are more valuable than you think.

Who has the power to end poverty?

Poverty isn’t one simple, easy-to-identify problem. It’s a catch-all term for droves of problems that stem from many sources. It’s daunting to think about solving such a sprawling issue, but there’s power in that too. Change needs to happen at so many levels that everyone from local communities to big governments can make a tangible difference.

Below, TEDx Talks with creative ideas about how to make a dent in poverty at three different levels — local, national, and global:

**Become the leaders of your own community: Boniface Mwangi at TEDxKibera
Boniface Mwangi calls on his community to demand representation and take charge of it’s own future. Kibera, the urban slum around Nairobi, is the largest in Africa. Despite the creativity of local innovators and entrepreneurs, infrastructure remains unsound and human rights abuses are widespread. At TEDxKibera, Boniface calls on his neighbors to demand justice and take action before outside sources forge their future for them.

**For money, insert human rights: Susan Randolph at TEDxUConn
What’s more important for a government hoping to improve the lives of its citizens: growing its economy or strengthening its social safety net? According to Susan Randolph, one might not work without the other. She measures a country’s human rights achievements, relative to its GDP per capita. She’s found that a country’s economic growth is unstable when it’s not coupled with policies that secure citizens access to the food, health, education, housing, work, and social security that’s within the country’s means. Reducing poverty is hardly just about money; it’s about guaranteeing citizens reasonable levels of dignity and stability, too.

**In defense of foreign aid: Joe Cerrell at TEDxASL
Wealthy countries like the US and UK have impressive aid programs, but many of their citizens view these as a colossal waste of money that ought to be spent solving the problems at home. What that argument usually misses, however, is that foreign aid makes up a near infinitesimal portion of most national budgets and that even those modest investments make a tremendous impact. Concerns about implementation notwithstanding, Cerrell makes the case that the spending is well worth the cost.

On a rooftop in Rwanda, TEDxNyarugenge celebrates new ideas: On a Friday night this August, a diverse group of thinkers, innovators, activists, and artists gathered on a rooftop in Kigali, Rwanda for a night of TED Talks, live speakers, and new ideas.

Attendees shared their life goals, wishes, and hopes, and the things in life that make them feel brave on moveable chalkboards, while local alternative energy provider, Great Lakes Energy, lit up the night with hundreds of tiny solar powered lamps.
