Sustainable development is a development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The different ideas of sustainable development are: (i) Save electricity by using bulbs that consume less power. Turning off lights and fans and other appliances when it is not in use, using generators that store and preserve electricity, using solar lamps as much as possible etc. (ii) Switching to conventional sources of energy to save fossil fuels by using solar cookers, lamps, panels, wind mills, hydroelectric power plants, etc. to conserve fossil fuels and generate less pollution. (iii) Practicing eco-tourism, afforestation, and agro-forestry, and developing greener and better methods of irrigation to prevent wastage of water and soil erosion by surface runoff. (iv) Generating less waste by recycling and reusing materials in our daily lives. Consuming less plastic and non-biodegradable materials to reduce waste and filter it before releasing it into the environment.
