Scientist and inventors around the world are working to harness advanced technology and save the environment. Young Post takes a look at some latest technologies that are making the Earth a better place to live.
1. Tele-conferencing
Travelling to meetings and conferences is expensive and time-consuming.
Climate ActionNetwork, a group of organisations that works to limit people's impact on the climate, says tele-conferencing is the way to reduce our travel and carbon footprints.
A two-day business trip to a place 1,000km away by one person equals about half a tonne of carbon, while a video conference uses none.
British Telecom, for example, has used video-conferencing technology to replace nearly 900,000 face-to-face meetings, eliminating 97,000 tonnes of carbon dioxide emission in one year.
