Want to know what you didn’t know before? Here’s the first in our series of what you didn’t know about… electronic art. We talk to a veteran electronic artist who’s been playing around with computers since the old Commodore and Amiga machines connected to TV sets. He’s linking and looping, moving from one networked idea to the next. See if you can follow his rapid-fire monologue about his digital works.

The old saying goes “Hijo de tigre, sale pintado”. Literally, it means the baby tiger is going to bear the same marks as his father. But it also means that there are some things we inherit and carry with us. Here, Aterciopelados is singing about leaving some inherited, violent habits behind.

New York has the Hudson; Paris has the Seine; London has the Thames. Rivers were important in the building of these cities: they were commercial routes and also a source of food. Aterciopelados (in English, literally “The Velvety Ones”) the well-known Colombian band, remind us of the importance of our rivers with the title song of their socially conscious album Río.

Martin, Eduardo and Karla travel around Chubut province in Argentina, learning about and filming each area’s fauna. Here, they are on the Valdes Peninsula to learn about this precious protected area. The Patagonian peninsula is a breeding ground for elephant seals and penguins. It’s like a big maternity ward each spring!

Should government pump money into the economy and generate jobs by financing giant public works projects? In the extremely close Mexican presidential election of 2006 (which he lost), Andrés Manuel López Obrador made it clear that that his answer is a decisive ¡Sí!

We are at Mexico City’s public university talking with Manuel. He tells us about the contrasts that exist within his neighborhood and what he thinks about the relationship between the United States and Mexico.

Colombia's Aterciopelados ("The Velvety Ones") delivers another smooth song with a political message. This time, the band questions immigration policies and asks who has the right to dream of a better life.

Iker Casillas, the famous goalkeeper of the Spanish national team and Real Madrid, makes an appeal with the NGO PLAN campaign to help Haiti after the 2010 earthquake.

Learn from the girls of "Sin Desperdicio" (Without Waste) about their new campaign for cleaning up the environment. It's called "Not one more bag."

After a dramatic, illegal entrance into a Colombian world heritage site, the Tayrona Natural National Park, our hostess explains the reasons why this is damaging to the park's ecosystems as well as giving us an introduction to the many adventures that await us in future episodes of this seven-part series.

In part two of this seven part series about Colombia’s Tayrona Park, María Cecilia Sánchez escapes her frenetic city life to explore this natural national park from the standpoint of nature conservation, enlisting the help of field expert, José Castro, who explains geographic, historical and touristic aspects of the park's terrestrial ecosystem.

Two Colombian children speak about their love for different kinds of diving: a young boy who practices the sport of high diving in a swimming pool and a girl who loves the freedom of scuba diving in the limitless sea.

María Cecilia continues her exploration of Tayrona Park, embarking upon her first scuba dive to explore its underwater ecosystem.

Part four of this seven-part series about Colombia's Tayrona National Park explains a bit about the importance of its coral reefs and how they are studied.
