Our world cares and nurtures over 7 billion people -which is rapidly rising-, drains about about 400 quadrillion BTUs of energy each year, and desperately tries to meet the basic needs of every human being. Every year, we demand more and more from our Mother Earth while her supplies cannot replenish as fast as we take, and consequently, will not meet our energy needs in the next upcoming years. Specifically in the United States, in 2014 we consumed nearly 80.50 quadrillion BTUs of energy from…

Population is defined as the total number of people which inhabit a specific area. For example, the population of the Earth is roughly 7 billion and the population of Australia is about 24 million. This number is steadily rising due to population growth. Every year, 135 million people are born and 55 million people die, which leads to the adding of 80 million people to our global population annually. The rate at which the population of a country increases compared to the initial population is…

Population aging, a worldwide phenomenon is changing age structure of the society. The world’s population proportion of aged 60 years or over increased by 4 percent (from 8 to 12 percent) since 1950 to 2013 (UN, 2013). It is predicted that it will rapidly increase in the next four decades, reaching 21 percent in 2050 (UN, 2013). In the U.S. the proportion of people more than 65 years represented about 14.1 percent (44.7 million), about one in every seven Americans in 2013 (ACL, 2014). By 2040,…

Good Morning 7W and Ms Florido/ Mr Kazokas, the topic for this debate is that the One Child Policy is wrong in the Catholic Church, and I believe that this statement is false. In the early 1970s, birth rates in china were around 4.77 percent, and that had decreased to 1.64 percent in 2011, and therefore allowing less people in the future generations and then creating less of human activity on the earth. Recently, the Pope has been around the world preaching about climate change and the effect of…

BAtrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice, particularly in the aged population. Incidence and prevalence of AF have constantly been on the rise over the last decades and expected to double by 2050, partly because of growing aging population. It has been estimated that AF is affecting 8-9% of people aged 80 years or more and 35% of patients with AF are > 80 years of age(1, 2). Epidemiologic studies estimated AF to be in the rage of 1-2% of the…

Introduction: In order to understand the concept of life expectancy, scientists use life tables to calculate age-specific life expectancies. Life expectancy is the average number of years that an individual of a given age is expected to live into the future. A life table is defined as an age-specific account of mortality (Smith, 1955). To put it simply, it represents a population’s survivorship. One standard method is to collect data on a cohort which is a group of individuals born in the same…
