If humans start constructing cities on Mars , we have an opportunity to build sustainably from the start. A Massachusetts Institute of Technology (MIT) team designed an environmentally friendly city for the red planet that mimics a forest , with solar-powered dome tree habitats connected with roots, or tunnels. Their vision, called Redwood Forest, recently won first place in the Mars City Design competition’s architecture category. As many as 50 people can reside in each one of Redwood Forest’s domes, which offer open space with plants and water – harvested from Mars’ northern plains – atop roots with access to private spaces and other domes. The roots also protect colonizers from cosmic radiation, extreme thermal changes, or micrometeorite impacts.

MIT doctoral student George Lordos said, “Every tree habitat in Redwood Forest will collect energy from the sun and use it to process and transport the water throughout the tree, and every tree is designed as a water-rich environment. Water fills the soft cells inside the dome providing protection from radiation, helps manage heat loads, and supplies hydroponic farms for growing fish and greens.” Solar panels will generate energy to split stored water to produce oxygen and rocket fuel, Lordos said. Solar power will also help charge hydrogen fuel cells , “necessary to power long-range vehicles as well as provide backup energy storage in case of dust storms.” These ideas wouldn’t only work on the red planet. The MIT team says many of their design features could be applied to Earth. Underground multi-level networks could ease traffic above by offering an alternative route for electric cars. Hydroponic gardens underneath cities could cultivate fresh produce with lower transportation and land costs. And their tree habitat design, MIT said, “could create living and working spaces in harsh environments, such as high latitudes, deserts, and the sea floor.” + Mars City Design Via MIT News Images via Valentina Sumini/MIT

‘Galapagos of North America’ – Mexico creates massive marine reserve

Comments Off on ‘Galapagos of North America’ – Mexico creates massive marine reserve

In a huge win for the environment, Mexico’s government just announced the creation of a massive marine reserve in an area known as the ‘Galapagos of North America.’ Aimed at protecting and preserving the precious environment around the Revillagigedo Archipelago near Baja California, the Illinois-sized reserve will be the largest of its kind for the continent. The 57,143-square-mile reserve will go a long way towards protecting the humpbacks, migratory birds, rays, turtles, endangered fish and coral reefs that call the area home. With the designation, all hotel construction, fishing, and mining are banned. The reserve sits 242 miles south-west of the Baja California peninsula and contains four volcanic islands and a submerged volcanic mountain range. Related: We created enough marine reserves last year to cover Texas and Alaska combined President Enrique Pena Nieto made the announcement on Friday, pushing back against significant opposition from the commercial fishing industry, saying that Mexico is reaffirming its “commitment to the preservation of the heritage of Mexico and the world”. The area will be policed by the Mexican Navy, a move that helps to silence critics that say marine reserves aren’t adequately patrolled. It’s worth noting that while Mexico is making a commitment to protecting priceless places, Trump is considering shrinking the Rose Atoll and the Pacific Remote Islands, two national monuments that could be opened to fishing.
