Slicing through the oceanic depths, sharks are graceful creatures with a row full of teeth that have haunted nightmares and received a dedicated viewership during Shark Week. From tail tip to nose, the shark skeleton is all cartilage, and its jaw is unattached at the skull, meaning that the jaw can enlarge to swallow large prey.


Gracefully statuesque with muscular shoulders and a long, arching neck, giraffes roam the African savanna, grazing from the treetops. Their legs are often longer than 6 feet, and they can reach speeds of 35 miles per hour for short distances. These tall creatures with goofy faces, long purple tongues, and an array of individual spotting patterns flaunt two horns alongside their ears that mimics a crown.


While determining criteria for a sustainable building is a relatively new development, the first definition of sustainable development that was internationally recognized occurred in 1987 in the publication of the Report of the World Commission on Environment and Development: “Our Common Future.”

According to the report, sustainable development is considered development that not only meets the present needs of society but also does not compromise the needs of future generations.
