SCIENCE FOR SUSTAINABLE DEVELOPMENT            

 

INTRODUCTION

Science is the integral part of human development. No man can deny that science has brought many changes both good and bad . Science is a systematic endeavor that  builds and organizes  knowledge in the form of testable explanations and prediction about  the universe. Thus Science can be used to preserve our earth from falling apart due to our actions. As sustainable development say, one should save our earth for our future generations,they must not suffer for our mistakes. Science has an integral role in sustaining earth.

 Science is critical to tackle complex challenges for humanity such as climate change, biodiversity loss, pollution and poverty reduction, as it lays the foundation for new approaches and solutions. How can science best fulfill this commitment to society? How can we create dynamic connections between knowledge and action? These concerns have led to a new approach: sustainability science.

In sustainable development science produces many ideas to reduce pollution and save non- renewable resources like petroleum and diesel. Different types of filters are used to filter dangerous carbon compounds from wreaking havoc in the atmosphere.The other features of science for sustainable development are:-

Energy

 The key technologies of sustainable development include new energy and propulsion technologies that will help reduce emissions of climate-damaging greenhouse gases. Simply to stabilize atmospheric greenhouse-gas concentrations at twice their pre-industrial levels, we will have to reduce current global greenhouse emissions by over 50% .Germany has set a goal of reducing CO2 emissions by 25% by the year 2025, with respect to the 1990 level. Achieving this goal involves focusing on improved thermal insulation in buildings, on the use of heat/power co-generation, and on efficient support for the use of renewable energies. Currently the most progress is found in the area of wind energy; in the medium term, the use of solar energy, with photovoltaic technology, will continue to grow in significance. An honest consideration of our options indicates that we cannot afford to discontinue peaceful use of nuclear energy.

Bio technology 

Biotechnology is expected to bring important advances in medical diagnosis and therapy, in solving food problems, in energy saving, in environmentally compatible industrial and agricultural production, and in specially targeted environmental protection projects. Genetically altered microorganisms can break down a wide range of pollutants by being used, for example, in bio-filters and waste-water-treatment facilities, and in the clean-up of polluted sites. Genetically modified organisms can also alleviate environmental burdens by reducing the need for pesticides, fertilizers, and medications.

Closure of substance cycles.

Modern microsystems and control technologies are also providing new opportunities to design environmentally friendly production processes. While filter and wastewater-treatment technologies have considerably enhanced air and water quality in recent years, they are never more than the second-best solution, and have been surpassed by integrated environmental technology, that is, technology that optimizes the use of materials and energy. This involves material-efficient, energy-efficient production processes as well as the manufacture of environmentally compatible products, especially those that generate little waste. We have created the necessary framework for this with the Closed Substance Cycle and Waste Management Act, which came into force in 1996. Instruments such as eco-audits, which help identify the saving potentials from environmental protection investments, also promote development of such “clean” technologies.

CONCLUSION

These show us amble example that science has a major role in creating a better world. We focus on technology which give importance to the environment. The world should not destroy our resources and save for coming generation. Let us give hope to the upcoming generation. They should get a better future.Sustainable development can succeed only if all areas of the political sector, of society, and of science accept the concept and work together to implement it. A common basic understanding of environmental ethics is needed to ensure that protection of the natural foundation of life becomes a major consideration in all political and individual action. A dialogue among representatives of all sectors of society is needed if appropriate environmental policies are to be devised and implemented.
