NASA is using a system of satellite and lasers to create a 3D map of the world's forests in order to determine the amount of carbon dioxide that they encapsulate. The system they've devised, called "lidar," is phenomenal, and is the latest advancement in tree cartography. Learn more below.

Norway is investing $1 billion to create a system of two-lane bicycle highways that connect the country's nine largest cities. The hope is that this new infrastructure will greatly reduce the impact of emissions, and the goal is for at least 10% of journeys to occur by bicycle in 2030. We hope it works!

Architects in Ho Chi Minh City were asked to create a new university campus. Taking into account the rapid urban sprawl and takeover of the natural environment, one group created a beautiful design that purposefully invokes a city overrun by vegetation. Seems almost post-apocalyptic. After seeing the photo spread, we definitely want to attend this university!

This week, we bring you a rather international smattering of fascinating projects. First up, South Korean artist Young Deok-Seo spends months welding and forming discarded bicycle chains into striking sculptures of the human form. Truly, this is powerful repurposing.

Second, Vietnamese architect Vo Trong Nghia designed three 22-story buildings in Ho Chi Minh City that each have a giant roof garden. The roofs are all connected by suspension bridges, making the completed structure a giant linear garden in the sky. Now that's what we call green architecture!

Finally, Donhou Bicycles, a London-based company, set off to construct a bicycle with a chain ring big enough to achieve pedaling speed of 80mph. Theirs is a great story of determination and innovation.
