Game-Changing Green Advancements You Should Know About I just read an article from the Huffington Post and had to share a portion of it. They showcased 7 items in the works for Green Advancement worldwide. Here are four that particularly caught my attention. I am especially excited about the green concrete.Concrete might not seem un-green at first, but it's actually the third largest source of man-made carbon dioxide! However, several companies are working on changing that. Enter "green concrete," which not only makes concrete carbon-neutral but even turns it carbon-negative. CO2 absorbing concrete is nothing short of a game-changer.This isn't a ferris wheel, it's the LO2P: Delhi Recycling Center, a concept by firm Atelier CMJN. Built from parts of recycled cars from local junk piles, this novel greenhouse has wind turbines that serve as bio-lungs. While it's still just a concept, it won first place in this year's eVolo Skyscraper competition, which means that the greenest buildings of the future will be of an entirely different ilk than we're used to.When it comes to green, bigger is almost never better. In that spirit, a new generation of homeowners and homebuilders are focusing on living in tiny eco-friendly homes. Gone are expansive kitchens and bedrooms; instead the focus is on integrating your life as much as possible with the outdoors, and winnowing down your lifestyle in size but not in style. Indeed, many of these tiny homes are very design-focused.Forget green building--consider entirely green cities. Tianjin Eco-City in China, slated for completion in 2020, will span 30 square kilometers and will include "an advanced light rail transit system and varied eco-landscapes ranging from a sun-powered solarscape to a greenery-clad earthscape for its estimated 350,000 residents to enjoy."
