Since long it has been realised that the exploitation of fossil fuels, metals and other non renewables cannot continue unchecked. Expression of worldwide concern about sustainable industrialisation and development led to the first UN Earth Summit in Rio de Janeiro in 1992. The Summit defined the objectives of the sustainable development which included avoiding depletion of non-renewable resources, protection of environment, social equity and justice.
The International Energy Agency in the year 2003 predicted that with increasing energy demand, the world's supply of crude oil will peak around 2014 and that coal will last until the year 2200. The decline in available coal and crude oil should cause their prices to go up which would limit their use. Moreover the use of fossil fuels has been identified as a major factor contributing to global warming. To address the problems due to global warming, the international community agreed to
have Kyoto Protocol in 1997, which envisaged a reduction of CO2 emissions by 5.2% below 1990 levels by 2012. The use of renewable energy was to be increased to by 2003 and 10% by 2010.
The Governments in United Kingdom and India have also stressed the need to create a low carbon economy and to have a low carbon footprint for the individuals. In response, countries like India have started searching for alternative energy sources. In this quest for developing new sources of energy, Biotechnology can play a significant role by identifying biological agents, tools and techniques for producing biofuels. This would help in achieving the goal of energy security for the country to a great extent.
15. What are the main objectives of sustainable development
16. What is the major cause of global warming and how does it occur
17.
What was the main resolution of Kyoto Protocol
