Deliberate exploitation of natural resources and excessive use of environmentally abhorrent materials have resulted in environmental disruptions threatening the life support systems. A human centric approach of development has already damaged nature to a large extent. This has attracted the attention of environmental specialists and policy makers.

Biodegradable materials are used in packaging, agriculture, medicine and other areas. In recent years there has been an increase in interest in biodegradable polymers. Two classes of biodegradable polymers can be distinguished: synthetic or natural polymers. There are polymers produced from feedstocks derived either from petroleum resources (non renewable resources) or from biological resources...

(31 Aug., p. 819) argue that, because current pricing practices do not internalize environmental costs, some mechanism other than the market is needed to protect environmental values. They propose a system of environmental credits-natural resource units (NRU's)-to be allocated to individuals and industrial organizations. Although their system is ingenious, I offer the following objections. 1) T...

Global increases in consumption of chemical nutrients, application of pesticides, and water withdrawal to enhance agricultural yield have resulted in degraded water quality and reduced water availability. Efforts to safeguard or improve environmental conditions of agroecosystems have usually focused on managing on-farm activities to reduce materials loss and conserve habitat. Another management...

This article examines the scope for strategies to build natural assets in the hands of low-income individuals and communities. Natural assets include sources of raw materials such as forests and fisheries, and the airsheds, lands, and water bodies that provide environmental sinks for the disposal of wastes. These resources become assets when people have rights to access their benefits. Four str...

ethanol producing bacteria are useful in industrial production of biofuel. there are interesting for screening of active bacteria from natural resources and introduce to biofuel industries. the present study aims to isolation of ethanol producing bacteria with characterization, optimization, and evaluation of their ethanol productivity. samples from various fruits, plant saps and soils were scr...
