Earthquake Fatalities

Modern global earthquake fatalities can be separated into two components: (1) fatalities from an approximately constant annual background rate that is independent of world population growth and (2) fatalities caused by earthquakes with large human death tolls, the frequency of which is dependent on world population. Earthquakes with death tolls greater than 100,000 (and 50,000) have increased with world population and obey a nonstationary Poisson distribution with rate proportional to population. We predict that the number of earthquakes with death tolls greater than 100,000 (50,000) will increase in the 21st century to 8.7±3.3 (20.5±4.3) from 4 (7) observed in the 20th century if world population reaches 10.1 billion in 2100. Combining fatalities caused by the background rate with fatalities caused by catastrophic earthquakes ( >100,000 fatalities) indicates global fatalities in the 21st century will be 2.57±0.64 million if the average post-1900 death toll for catastrophic earthquakes (193,000) is assumed.

And Control

Using two Gallup polls, which together contained three questions on the attitudes of adult Americans towards population growth and control, a multivariate analysis was conducted of the relationship to each question of nine demographic factors: age, city size, education, family income, occupation of the household head, race, region, religion and sex. Only education and religion showed an intrinsic relationship with attitudes. Specifically, the extent of endorsement of the view that the world population growth rate is a serious problem, and of the view that population limitation will, at some time, be necessary, increased with education. Among those whose family income was at least $10,000 and those whose house-hold head was a professional or business executive, Protestants were more likely than Catholics to view US and world population growth rates as serious and to consider population limitation necessary.

World Population Growth

Recently, due to the rapid world population growth, decreasing of natural resources and raw materials, increasing environmental awareness, interesting for wasting raw materials, using produced products more efficiently, and reusing of sources is rapidly increasing. Nowadays, reverse logistics as an important business strategy for profitable and sustainability is becoming important. The effective implementation of reverse logistics gives companies a competitive advantage in sectors. Due to mentioned reasons firms intend to incorporate reverse logistics activities such as the recovery, remanufacturing, recycling or disposal. Reverse logistics has become increasingly important as a profitable and sustainable business strategy. Therefore, more and more manufacturers have adapted the practice of recovering value from returned products and integrate product recovery activities into their processes. The electronic industry is one of the fastest growing manufacturing industries and the main purpose of this chapter is to explore the opportunities for waste returns within this sector.
