Society & Environment

At the present time many issues that are of interest to the general public have an environmental dimension. This ranges from natural and human-caused disasters to concerns about climate change and energy needs. The discussion of environmental topics was probably not very prominent in the formal education of most citizens so other modes of communication and participation have developed over recent years. This includes the work of various advocacy groups as well as museums, zoos and other informal education venues. The EoE aims to provide accurate environmental information to assist readers at all levels in making personal choices that relate to our world.

Lubbock Lake Landmark Last Updated on 2014-08-21 20:56:24 The Lubbock Lake National Historic and State Archeological Park, known locally as the Lubbock Lake Landmark, is an archeological and natural history preserve located in Lubbock, Texas, USA. The 300 acre preserve is located in Yellowhouse Draw, an intermittent tributary of the Brazos River. This reserve, which is managed by the Museum of Texas Tech University, is important because it contains evidence of nearly 12,000 years of use by humans as well as records of now extinct species that formerly lived in this area. It is one of the few places in North America known to have a complete record of human existence from the Paleo-Indian culture all the way through the Archaic, ceramic, and Prehistoric cultures. Lubbock Lake Landmark received its name from a reservoir that was created in the 1930s. This area housed a natural spring fed lake until the spring began to... More »
Sustainable Society Index Last Updated on 2014-07-31 13:15:01 When we were looking for a suitable yardstick to measure the level of sustainability of a country a suitable instrument could not be found. Although the main existing indexes were examined we had to conclude that none of them seem to fit our needs completely. The main shortcomings are a limited definition of sustainability, a lack of transparency or high complexity and an absence of regular updates. For this reason, a new index – the Sustainable Society Index (SSI) – has been developed. The SSI integrates the most important aspects of sustainability and quality of life of a national society in a simple and transparent way. Consisting of only 22 indicators, grouped into 5 categories, it is based upon the definition of the Brundtland Commission, extended to the Brundtland+ definition by explicitly including the social aspects of human life. Using data from public sources,... More »
Food Biodiversity Challenges From a Global Perspective Last Updated on 2014-07-25 14:03:15 Food collection or gathering has been an important part of human endeavors towards establishing civilization across the long history of human evolution. Humans have demonstrated their ingenuity in identifying and locating new and novel food sources located in their immediate surrounding and during their migration across the planet. Humans have become more successful than other species because of their better foraging abilities and coordinated group work in identifying and locating novel food sources over time. This trial and error approach has enabled humans over time to identify suitable food sources from their local environments. Over time, humans have identified more species that are edible or could be made edible using primitive to modern day recipes and cooking techniques. These long years of trial and errors have generated a wide range of food sources for... More »
Population-environment theory and contemporary applications Last Updated on 2014-07-24 15:49:49 Introduction Humans have sought to understand the relationship between population dynamics and the environment since the earliest times (1-3), but it was Thomas Malthus’ Essay on the Principle of Population in 1798 that is credited with launching the study of population and resources as a scientific topic of inquiry. Malthus’ famous hypothesis was that population numbers tend to grow exponentially while food production grows linearly, never quite keeping pace with population and thus resulting in natural “checks” (such as famine) to further growth. Although the subject was periodically taken up again in the ensuring decades, it wasn’t until the 1960s that significant research interest was rekindled. In 1963 the U.S. National Academy of Sciences published The Growth of World Population, a report that reflected scientific concern about the consequences of... More »
Malaysia (collection) Last Updated on 2014-07-01 17:16:22 Welcome to the Malaysia Collection!  The purpose of this collection is to provide a reliable on-line resource for information about the ecology, biodiversity, environmental issues of Malaysia.  The Malaysia Collection is the first collection on the EoE to focus on a single nation.  The Malaysia Collection is very  much a work in progress.  Development of the Malaysia Collection is currently spearheaded by Mark McGinley, the Editor-in-Chief of the Encyclopedia of Earth and an Associate Professor at Texas Tech University. Malaysian scholars, or international scholars working in Malaysia, are invited to contribute to the Malaysia Collection by serving as Authors and Topic Editors.  In addition, university instructors are invited to have students write articles for the EoE as...
