The World Population Increases The Global Food Production

Literature Review Several studies (Oltjen et al., 1996; Dahlen et al., 2014; Thornton, 2010; and Tilman et al., 2002) drawn the conclusion that as the world population increases the global food production must as well. The current meat practices in the U.S are unsustainable in terms of being able to meet the future demands of global society (Dahlen et al., 2014). Although livestock practices have changed dramatically over time to make production more efficient it has negative impacts on the environment and human health. Fortunately sustainable solutions do exist. Others livestock farmers around the world are implementing sustainable practice that improve the quality of meat and decrease their impacts on the environment. Current†¦show more content†¦In the next forty years food production will need to increase by one hundred percent if it is going to meet the demands of global society (Dahlen et al., 2014). The reproduction of livestock has undergone evolutionary changes over time all in favor of making production more efficient. Artificial insemination (AI), estrous synchronization and fixed-time AI (TAI), semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of beef operations (Dahlen et al., 2014). These are some of the newer technologies that have been generated to increase meat production. Food provides energy and nutrients, and its acquisition requires the expenditure of energy. In today’s world unbalanced nutritional diets lead to obesity and other serious health issues (McMichael et al., 2007). Lives tock raising is a major contributor to agriculture-related greenhouse gas emissions. Studies have been conducted to analyze what changes the meat industry would need to undergo to reduce the greenhouse gas emission levels. In order to reach the target level of greenhouse gas emissions the world would need to reduce their demand of animal products significantly (McMichael et al., 2007). The estimated average per-head intake of, at most, 90 g meat per day and not more than 50 g of this should come from red meat from ruminant animalsShow MoreRelatedThe Health Of The Human Race1269 Words   |  6 Pagesfor consumption of food and water. This dependency is crucial in order to maintain and sustain the future existence of humans on Earth. Unfortunately, as the world faces agricultural problems such as: price increases, overpopulation, and climate change, attaining food has proven to become more difficult. Food crises are issues that have plagued humans across the globe currently and histo rically.

This means that as the amount of available petroleum decreases over time, the need for alternative fuels will increase. This is an important matter because it affects global energy security, food security, the environment, and economies. With governments around the world attempting to cope with increasing greenhouse gas emissions, the world is turning to cleaner, more efficient energy use andRead MoreIs Food Production A Growing Concern?1473 Words   |  6 PagesThe world’s population is predicted to reach 9 billion by 2050. Will we be able to feed everyone, what are the problems likely to be and what do we need to overcome these problems?† Undoubtedly food production is becoming a growing concern as factors such as the rapidly growing global population and changing diets within developing countries stretch current production techniques to the limit. The total global human population is expected to increase by 34% by 2050 with this growth occurring predominatelyRead MoreEssay on Threats to Global Food Supplies691 Words   |  3 PagesThe world’s population is increasing every year and one disadvantage of this phenomena is the shortage of food supply. There is not enough food available for the world’s population to feed on, because of a lot of serious problems going on. This can only be resolved until there is a reliable solution to solve the ongoing matter. Thus, this essay will look into these problems, and identify possible solution, find if there’s any disadvantage in these solutions. In the next 40 years the world’s populationRead MoreProblems Associated With Food Shortages1397 Words   |  6 Pages Food Shortages According to Rajendra Prasad, â€Å"Improvements in agricultural technological advances in developing countries is the only true way of alleviating the threat hunger.

We experienced an increase by over 100% since 1968, a timeframe of just 43 years and it is expected to keep growing [1]. One of the main challenges of this development will be the supply, distribution and access of water, food and nutrition on a global scale, while reducing the impact on the environment. The earth warms up as a result of extraordinarily high greenhouse gas emissions, generating extremeRead MoreThe world’s population is increasing at a rapid rate.

According to Worldometers, by 2050 there will be a need to feed 9.2 billion people globally (http://www.worldometers.info/world-population/). This translates to an increase in global food production by 70 percent to meet the global goal (http://www.populationinstitute.org/resources/populationonline/issue/1/8/). However, current food production methods are not sustainable and the amount of arable lands is decreasing.
