QAQORTOQ, GREENLAND - JULY 30: Calved icebergs from the nearby Twin Glaciers are seen floating on the water on July 30, 2013 in Qaqortoq, Greenland. Boats are a crucial mode of transportation in the country that has few roads. As cities like Miami, New York and other vulnerable spots around the world strategize about how to respond to climate change, many Greenlanders simply do what theyve always done: adapt. "Were used to change, said Greenlander Pilu Neilsen. "We learn to adapt to whatever comes. If all the glaciers melt, well just get more land. (Photo by Joe Raedle/Getty Images)

The Ministry of Popular Power for Eco-Socialism (Minec), together with volunteers and naturalists, are developing a sea turtle conservation project aimed at protecting endangered species by collecting their eggs to nest them in a hatchery and releasing them into the sea after birth.

Computer illustration showing Earth's internal structure. The core consists of an inner region and an outer region. The mantle consists of the mesosphere, the athenosphere, and the lower part of the lithosphere. The crust is the upper part of the lithosphere. The crust is around 40 kilometres thick in the continents, and as little as 5 kilometres thick in the deep ocean. The mantle is a viscous layer of rock some 2900 kilometres deep. The outer core is a liquid composed of molten iron and nickel. Convection currents in these metals are responsible for producing the Earth's magnetic field. The outer core is around 2250 kilometres thick. Below it is the solid inner core which is a hot, solid sphere of iron and nickel, some 1200 kilometres in radius, at a temperature of around 5500 degrees Celsius.
