Abstract Fossil-based resources are finite; thus, materials derivable from these nonsustainable. As no methods for renewing the depleting fossil reserves have been discovered, humanity must seek renewable, sustainable, and efficient alternatives to satisfy its material needs preserve civilization. Solar energy remains “capital income” of global community is pivotal meeting current humankind by ...

The aim of this research was to investigate the environmental impacts of olive fruit production under different orchard size and upon organic and common agro-systems through Life Cycle Assessment (LCA) methodology in Rudbar region, Guilan province, northern Iran. The data were collected using a self-structured questionnaire and face-to-face interview with 305 olive growers in the study region. ...

The availability of fossil fuels will likely decline dramatically during the first half of the twenty-first century, and the massive deficits probably will not be alleviated by alternative sources of energy. This seeming catastrophe will create opportunities for communities to benefit from foods produced locally in ways that nurture relationships among soil, water, plants, herbivores, and peopl...

The world is reducing the use of fossil energy. Reducing carbon emissions will help protect atmospheric environment. Because geothermal resources are green, clean and free energy, these much accounted by many countries. This paper explains geological geophysical characteristics resources, summarizes research classification utilization expounds technical process difficult problems in resources. ...

Worldwide efforts are being made to increase the use of renewable energy in order to reduce the emission of greenhouse gases. Africa is blessed with abundant resources of fossil fuels as well as renewable energy resources. Yet the continent, especially sub-Saharan Africa, is afflicted with power crisis. For example, in Nigeria, erratic electricity supplies will persist unless the government div...

Sustainability is a key principle in natural resource management, and it involves operational efficiency, minimisation of environmental impact and socio-economic considerations; all of which are interdependent. It has become increasingly obvious that continued reliance on fossil fuel energy resources is unsustainable, owing to both depleting world reserves and the green house gas emissions asso...

Over the last 50 years, global agricultural food production has become increasingly dependent on use of non-renewable and/or scarce resources, and, in particular, fossil fuel (e [...]

More than 50 specimens of fossil crabs collected from the Cannonball formation (Paleocene) of southern Morton and Burleigh Counties, south-central North Dakota form the basis for the first report of fossil crustaceans in North Dakota. The new genus Camarocarcinus is created for their reception with the new species C. arnesoni as the type species. A separate, single, large propodus is placed in ...
