According to the royal society, between1930 and 2010 the world’s population grew from 2 billion to 6.8 billion ,so the Continuing population causes a consumption growth and that means the global demand will increase over the next years and growing competition for land, water and energy will increase too(Black, 2010). Growth of population will affect on some countries ability to produce food especially in the poor developing countries, so improved nutrition is central to improved income generation, poverty reduction, and provide a good food quality. Lack of food quality has an impact on mother’s nourishment because they are more likely to give a birth, so mothers which are malnourished later will give birth of babies with a less healthier, growth retardation are associated with reduced physical activity, impairment of
The prices of food increased as there was a higher demand for it. And the higher demand for food is caused by a growth in population. Although it was written in 2011, the author, Gail Tverberg, includes points that still apply today. “The urban poor will be worst off if food prices remain high, or go even higher, mainly because they must spend a much larger percentage of their incomes just to eat.” The high cost of living doesn’t only affect housing but also the everyday lives of everyday people. Low-wage workers are having to spend most of their incomes on important things like food and paying bills.
to about 90°F), the psychrotrophs grow more rapidly, causing spoilage and at the same time frequently interfering with the growth of foodborne disease organisms. Within the growth range, the rate of growth increases rapidly as the temperature is raised . Conversely, microbial growth rates decrease rapidly as the temperature is lowered and, hence, food spoilage occurs much more slowly. This effect is especially marked near the freezing point. Note in Figure 3 that a drop from about 41°F to about 32°F will more than double the shelf life (time before
As the world’s resources are becoming less by the day the world’s population is continuing to grow at an unsustainable rate. With the general public becoming more health conscious, the average lifespan has increased by 30 years over the past century. With the life expectancy almost doubling, the world’s population seems to be increasing at a rate that is unrealistic to support given the limited resources available. With people living longer lives, the world’s population will inevitably use up all of the natural resources, leaving nothing behind for future generations. Consequently, this is going to force the world to reevaluate the way we think about population control.
Both birth and death rates are high, as a result the population size remains fairly constant. Stage 2 - Early expanding: The introduction of modern medicine lowered the death rates, especially among children. The birth rates remain high, the result is rapid population growth. Stage 3 - Late expanding: The birth rates gradually decrease, this is usually due to a result of improved economic condition. Stage 4 - Low stationary: Both birth and death rates are both low, thus stabilizing the population.
The two major school concerning population growth both have aspects that can be considered correct and incorrect. The two major thoughts are pessimistic and optimistic side. The pessimistic side are called Neo-Malthusians which are people who believe that population will cause unsustainable amount of food for the people. The optimists who are called the Anti-Malthusians on the other hand believe that with human population increasing we will be able to find a solution to create a sustainable amount food for the population. The food security in the in the 21st century population has grown a massive amount and it is predicted to reach 9.5 billion people by 2050.
Where g is increasing firstly if birth rate increases with consumption per capita, people will have more children by choice, they are better able to provide for children and better nutrition increases fertility. Secondly, death rate decreases with consumption per capita. Decreases infant mortality and population more healthy, increasing the average lifespan. The above figure show population growth is higher the higher is per-capita consumption. Malthusian indicates that when population increases, land will reduce due to the limited land.
Overpopulation is where the number of people on earth exceeds the carrying capacity of earth. It is caused by a number of factors namely; reduced mortality rates, better medicinal care and technological advancements, for example. If the number of people who died constantly equaled the number of people being born then the world population would stabilize however this is not the case. Technological advances are perhaps the biggest reason for the imbalance. Science has been able to discover multiple cures for illnesses, and produce easier means of getting food, evoking an increase in the longevity of one’s life.
As birth rate rising and death rate decreasing, this will create rapid population growth in many countries. Hence, it can cause great threat in near future. (Kinder, n.d.) Due to rapid population growth, our resources, housing and job market will be affected. Natural resources are the most important things in our lives as they provide our survival.
(30) Nowadays, there is an increasing order for busy lifestyles and convenient products. Obviously, Fast-food industry is one of the cases. A percentage of progress in customer consumption on convenience food has led greater division of food beyond home for almost 20 years. (Jekanowski, Mark D., 1999) (75) Almost all of us ate in the fast food even though they know it’s not good for the health. The reason of doing such, according to Mr. Mark D. Jekanowski, (34) the result of acceleration, availability, and cost yet it carries hidden amount.
