How Global Food Production and Population Has Changed

Also, per capita food (grain) production increased by about 30% from 1950 through 1970. However, from 1971 through 1984 the trend began to change. Over the period from 1984 to 2005, production of grain declined by more than 7% according to Chiras. (Chiras, 2009)
Identify how many people are chronically hungry
As per the estimates by the Food and Agriculture Organization of the United Nations, the mean intake in calories per person rose over the period from 1961 to 2008. The number of persons that are chronically undernourished declined from around 918 million in the year 1970 to 852 million in the year 2005. (Miller and Spoolman, 2008) In 2009, according to the World Food Programme, approximately more than one billion people are chronically hungry. (wfp.org, 2009)
Why Hunger Persists in the World of Plenty
In this globe, there is enough food for everybody. Hunger persists, though. The reason why hunger continues to cripple the globe can be attributed to two things. Firstly, people cannot afford to purchase the available food. Secondly, most people cannot access the available food. (Forbes, 2009)
Identify Health Risks of Undernourishment, Poor Diet and Overeating
Undernourishment may be evident when few vital nutrients are consumed or using them in a more rapid manner than they are replaced. Consequences may differ in teenagers, children, and adults. For instance. it can cause death to anybody, inadequate intake of proteins can cause Kwashiorkor in infants or Marasmus if there is inadequate intake of all nutrients in infants.
Poor diet refers to malnutrition and it occurs when the human body does not get enough minerals, vitamins and other nutrients. The ramifications of poor diet range from death, to many other diseases (like goiter due to lack of iodine minerals and to obesity due to over-nutrition).
Overeating may be taken to refer to over-nourishment and it relates to taking an excess of essential nutrients and not having or taking enough exercise. Consequences may be many. from the negative effect on body senses like taste, sight or even smell to obesity. (Gilman, 2007)
