Introduction To ensure the continuity of humanity, we have to develop a sustainable world. Sustainability is divided into environmental, economic, and social sustainability. Environmental sustainability is attained through ensuring that the processes that people are involved with use up the natural resources at a rate at which they can be replaced naturally. Economic sustainability involves distributing and allocating the natural resources fairly to ensure economic growth while ensuring that we do not exhaust the resources. Social sustainability ensures that the well-being of individuals and the environment in which they live in are upheld (Ekins 48). This paper explores ways through which we can develop sustainable world both for ourselves and for future generations. A sustainable world I am living in a sustainable world. At home I use sustainable appliances that are energy-efficient. The source of energy for cooking, lighting, heating water and space and supporting other appliances is renewable and emits less harmful gases into the atmosphere. This energy is generated from renewable sources such as solar panels that use nanotechnology, geothermal power, hydroelectricity and wind, ocean energy. These sources provide energy which can be replenished and does little harm to the environment. To save on water, I use sound-wave showers and washing machines When going to wok every morning and I use sustainable means of transport. I can walk, cycle, drive, or use the car sharing service. My car is electricity powered and does not emit harmful gases into the atmosphere. When I come back home after a long day, I relax and get some entertainment. The entertainment gadgets are eco-friendly, mostly using solar energy. The music and audiovisual systems are all sustainable and energy-efficient. The cities have grown very big and most people live in them. The world is interconnected fully due to developments in information and communication technologies. Communication is greatly advanced and interaction with people is easy through GPS technology, internet, teleconferencing, and mobile phones. Everyone has access to a computer and the internet in their homes. Human intelligence can be enhanced through implanting computer chips into the brain. Contents of a human brain can be read by uploading them to a computer. In education, topics that encourage people to work towards maintaining sustainability have been incorporated in the curriculums. There are topics about global warming, globalization, healthy eating, healthy lifestyle, importance of using renewable energy and efficient consumption of energy. The home designs and the materials used in the construction of houses are also sustainable. Sustainable homes are built with renewable raw materials such as bamboo, hemp, natural rubber, linoleum, among others. Both land and air transports are greatly advanced. People are using sustainable means of transport like cycling, walking, sailing hybrid vehicles, solar and hydrogen powered vehicles. Air transportation is also sustainable. The aviation industry is able to meet the high air transportation demand and has reduced negative effects on the environment. Air transportation is efficient because of adoption of the mechanism where several planes fly together while being directed by one leader. The
