3 R for Sustainable Development
4 likes6,457 views
The 3 R's of the environment are reduce, reuse, and recycle. Reduce means to use less and create less waste by conserving resources. Reuse means to extend the life of items by using them again or for a different purpose before throwing them away. Recycle means to convert waste materials into new reusable materials through a process that uses energy. Appropriate technology aims to use resources efficiently and minimize pollution and waste to support sustainable development.
3 R for Sustainable Development
- 1. 3 R's Of Environment
- 2. Reduce • Reduce: to make something smaller or use less, resulting in a smaller amount of waste. • "Source reduction" is reducing waste before you purchase it, or by purchasing products that are not wasteful in their packaging or use. • A key part of waste "reduction" is "conservation" / using natural resources wisely, and using less than usual in order to avoid waste.
- 3. How to Reduce Buy products that can be reused – We can reduce waste by using a computer! Many newspapers and magazines are online now. Instead of buying the paper versions, you can find them on the Internet. – Save energy by turning off lights that you are not using
- 4. Reuse •Reuse: to use again or more than once •Reuse materials and items so that they have longer life spans and don’t get thrown away after the first use. •Many items found around the home can be used for different purposes. •So before you throw those items away, think about how they can be reused.
- 5. How to Reuse • Newspaper, cardboard and bubble wrap Make useful packing material when moving house or to store items. • Old clothes Can be made into other textile items such as cushion covers. • Scrap paper Can be used to make notes and sketches. • Rechargeable Batteries Can be reused many times before they need throwing away
- 6. Recycle • Recycle: to convert materials/waste into reusable material • Recycling puts objects through a process (it consume energy) that allows them to be used again.
- 7. How to Recycle • Example Used plastic or metal objects can be sold in scrap where they can be recycled to create new usable objects
- 8. Appropriate Technology Technology should use less resources and produce minimum waste • Conservation of energy:- • Conventional source of energy are not renewable. Ex. Coal, Oil, Gas. • This also cause emmision of green house gases like CO2. • It causes global warming. • Fossil fuel must be used more efficiently
- 9. Appropriate Technology • Conservation of Water:- • Potable water is very limited. There are areas in world where water is scare commodity • Wastage of water is must be prevented • It is necessary for sustainable growth
- 10. Appropriate Technology • Biological resources:- • Steps should be taken to prevent natural vegitation, biodiversity, forest. • Lack of vegation will cause soil erosion • Disturbance in biodiversity will affect ecological system
- 11. Appropriate Technology • Reduction of pollution:- • Uncontrolled use of fossil fuel causes air pollution. • Improper disposal of sewage water will affect natural water resourses and cause water pollution • Solid waste cause soil pollution which affect fertility of soil • Hence reduction of pollution is necessary
- 12. Appropriate Technology • Consumerism:- • People consume more than they produce • US has only 4.7% of worlds population but consume 25% of worlds resources • Consumerism should be controlled for sustainable development
