According to Miller and Spoolman in Sustaining the Earth (2015), we are about 7.1 billion people on the planet and this number will increase to 9.6 billion by 2050. As a result, many people do not have access to food and clean water. According to the World Bank, “about 900 million people almost three times the U.S. population live in extreme poverty,
According to Jones, humans are 10,000 times more common than they should be. In other words, visualize getting stuck the whole life in a room that’s capacity is fifty people instead there are one-hundred people. Undoubtedly, many individuals if not all people will get sick, and that’s because there wouldn’t be enough food for everybody. Secondly, people will die because there would not be enough air (oxygen) for them to breathe, which causes the spread of diseases. We should have more control over overpopulation since it causes the spread of diseases, starvation, and the utilization of agricultural space; on the other hand, some believe that overpopulation is an advantage.
From 2010 to 2013, the life expectancy for men was still lower: 68.5 years and for men and 73.5 years for men (World). So why is life expectancy so important to know? If you know a country’s life expectancy, you know the country’s healthcare technology, economics, education, and etc. (Khalsa). Will women still have a higher life expectancy in the future too?
Living a longer life likewise means a greater strain on the economy as well as the environment. According to the Social Security Administration, a steady increase in the older population over the age of 65 will put a severe strain on federal programs such as Medicare and Social Security. To put simply the system as we know it will crumble. Now imagine what this would do with the ecological, social, and economic environment. Brian Bienkowski wrote "As People Live Longer, Threats to Wildlife Increase “Increased life expectancy means that people live longer and affect the planet longer; each year is another year of carbon footprint, ecological Laurinaitis 3 footprint, use of natural resources, etc.
Longer life expectancy is arguably one of humanity biggest achievements. Medical progress, public-health efforts, rising standards of living, better education, healthier nutrition and a more hygienic lifestyle in the past century lead to an substantial increase in life expectancy worldwide. (1) In developed countries around 30 years in life expectancy have been gained, in these societies the oldest-old group – i.e., those aged 80 and over – have been the most rapidly expanding segment of the population over the past decades. (2,3) It is expected that by 2050, the worldwide population of older adults (more than 60 years old) may grow to nearly 2 billion, with 80% of that population living in developing countries. (4) However, humanity’s big achievement has its pitfalls; the years gained in life expectancy might be years with disability, since disability increases with age, and therefore people are not only living longer but are also experiencing morbidity and disability over a longer period.
And the person in this situation are always eat a food with not be fully nutritious. II. According to the United Nation Food and Agriculture Organization for 2013, about 870 million people in the world do not consuming enough food to eat and to be healthy. This is a large amount that can make a global poverty. That means the one in every eight people on Earth goes to bed hungry each night and Asia is the continent with the most hungry people III.
That is crazy when you compare it to the other big landmarks. The growth of our population is exponential, and it has really showed that in the past 50 years or so. There are quite a few reasons our population is growing so fast. Not only are there more people meaning more births, but death is a lot less "common" now. Advancements in technology means better medical services, we now have cures and vaccines to diseases that used to kill thousands.
Almost 60% of Latin America’s poor reside in Urban areas, 30% of Eastern Europe’s and Central Asia’s, Less than 30% of Sub-Saharan Africa’s, 20% of South Asia’s, Less than 20% of Middle East’s and North Africa’s and 10% of East Asia and Pacific’s reside in urban areas. Source: Ravallion, Chen, and Sangraula (2007) Moreover, according to Socioeconomic Data and Application Centre, Columbia University, Poverty Maps report, the world is undergoing significant transformation. As the population of world will be more in urban areas than rural. Africa and Asia are the two regions of the world expected to undergo the most rapid urban change. As it is going to reflect in the world’s poorest countries because they are they have least resources to invest in infrastructure to support them, viz-a-viz, housing, water and sanitation facilities; and least opportunities to avail and climb up to reach above poverty line.
The leading cause of death in the world is hunger. Today, around twenty one thousand children die around the world due to poverty. Although the root of the problem does not solely lie on the wealthy, the root of the problem is the improper allocation of our resources. A new study from McGill University and the University of Minnesota published in the journal “Nature” shows that in a year, the world produces enough food to feed ten billion people and that’s like 1 ½ of our total population. But still billions go to sleep hungry every night.
