The Muni Seva Ashram in Goraj, near Vadodara, India, is a tranquil haven of humanitarian care. The Ashram is hugely sustainable, next year it will be completely carbon neutral. Its first solar panels were installed in 1984, long before climate change was on anyones agenda. Their energy is provided from solar panels, and wood grown on the estate. Waste food and animal manure is turned inot biogas to run the estates cars and also used for cooking. Solar cookers are also used, and the air conditioning for the hospital is solar run. 70 % of the food used is grown on the estate. They provide an orphanage, schools for all ages, vocational training, care for the elderly, a specialist cancer hospital withstate of the art machinary, and even have a solar crematorium. This shot shows solar panels that focus the suns rays on heat exchangers to boil oil, which is then sent down to the kitchens below to heat the cookers.

High Mountain Rangers Tom Ditola and David Weber are taking a rest on the West Rib on Mount McKinley, Alaska. Mount Hunter in the background. They are above the clouds in blue sky and the sun is shining. Mount McKinley, native name Denali, is the highest mountain peak in North America, with a summit elevation of 20,321 feet (6,194 m) above sea level. At some 18,000 feet (5,500 m), the base-to-peak rise is considered the largest of any mountain situated entirely above sea level. Measured by topographic prominence, it is the third most prominent peak after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, McKinley is the centerpiece of Denali National Park and Preserve. Every climbing season High Mountain Rangers of the Denali National Park Service are called to help climbers in need. If possible the patient is brought down to base camp on foot, only in life threatening conditions a helicopter is called to evacuate the patient to a hospital in Anchorage.
