Acabar com a sobrepesca

Despite an increased awareness of overfishing, the majority of people still know very little about the scale of the destruction being wrought on the oceans. This film presents an unquestionable case for why overfishing needs to end and shows that there is still an opportunity for change. Through reform of the EU's Common Fisheries Policy, fisheries ministers and members of the European Parliament can end overfishing. But only if you pressure them.

Asteróide 2012 DA14 vai passar muito próximo da Terra no dia 15 de Fevereiro

The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so close that it will pass inside the ring of geosynchronous weather and communications satellites. NASA's Near-Earth Object Program Office can accurately predict the asteroid's path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth. Nevertheless, the flyby will provide a unique opportunity for researchers to study a near-Earth object up close.

Asteroid 2012 DA14 will be closest to Earth on Feb. 15, at about 11:24 p.m. PST (2 p.m. EST and 1924 UT), when it will be at a distance of about 27,700 kilometers (17,200 miles) above Earth's surface. Although this is close enough for the asteroid to pass inside the ring of geosynchronous satellites, located about 35,800 kilometers (22,200 miles) above the equator, it will still be well above the vast majority of satellites, including the International Space Station. At its closest, the asteroid will be only about 1/13th of the distance to the moon. The asteroid will fly by our planet quite rapidly, at a speed of about 17,400 mph (7.8 kilometers per second) in a south-to-north direction with respect to Earth.

Sapatos GPS

GPS shoes by Dominic Wilcox. The shoe worn on the left foot (on the right in this photo) has a circular set of lights to indicate the direction a person should walk. The shoe worn on the right foot lights up red lights sequentially to show progress with a green light at the end once the destination has been reached.
