Yet, in the world today there is an even greater fuel shortage, that can create an even greater human catastrophe, as trees create the oxygen that makes it possible to breath. A the urgent need to develop more climate-friendly energy technologies is becoming keenly appreciated worldwide. Renewable energy technologies are receiving heightened attention, and modern biomass-based energy -- the use of wood, crop residues and dung as fuel -- is

The modern separation from the means of production does not negate the fact that nearly everything we need to sustain us is provided by the earth, either by natural or artificial means. The earth gives us all the materials we need and many we desire and in turn she is changed. She becomes less able with each passing day and each lost natural acre to continue to provide. Though the

Urbanization Earth also witnessed a phenomenon of urbanization or shifting of population toward cities. The increase in the number of cities has been associated with that of repeated ecological disaster. Rapid regional deforestation, the depletion of ground-water aquifers, accelerated soil erosion, plant genetic simplification, periodic outbreaks of disease among pest species and domesticated animals, large-scale human malnutrition, and the development and spread of epidemics are some of the results we have

"And Sarah said unto Abraham: Behold now, the Lord hath restrained me from bearing" (Genesis 16:2, quoted by Thomlinson). But a more scientific approach has been forwarded and it aimed to find solutions. For instance, in the case of couples where the man is sterile, the woman could choose to be artificially inseminated; or in the cases when the woman is sterile, the man could inseminate a surrogate mother.

It deals with inbuilt societal problems that cannot simply be dealt with due to the fact that they are so internalized. They therefore require a restructuring of societal systems -- that is, a transition and this can be done -- according to Rotman and Loorbach (2008) - by looking into the social structure of the problem Transition management has already come a long way. As Rotman and Loorbach D (2008)

The developed countries hence experience higher survivorship for most age groups resulting in a balanced and healthy reproductive structure. The age distribution needs to complement or mirror the high survivorship ratio as the extinction of even one age group is very much possible with a single unforeseen natural event (Begon et al. 2006). To illustrate the importance of a balanced age structure, consider this example. A huge carnival targeted for
