The world’s inability to completely shut down WikiLeaks servers illustrates that a small but determined cyberwarfare team can compete with the best information-warfare machines on the globe. What’s more, the built-in characteristics of the Internet that make it so resilient also make it impossible for a single entity to truly control information.

Sustainability is the capacity to endure. For humans, sustainability is the long-term maintenance of well being, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use. In ecology, sustainability describes how biological systems remain diverse and productive over time, a necessary precondition for human well-being. Long-lived and healthy wetlands and forests are examples of sustainable biological systems.
Technology is the making, usage, and knowledge of tools, machines, techniques, crafts, systems or methods of organization in order to solve a problem or perform a specific function. It can also refer to the collection of such tools, machinery, and procedures. The word technology comes from Greek τεχνολογία (technología); from τέχνη (téchnē), meaning “art, skill, craft”, and -λογία (-logía), meaning “study of-”. The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology.
