"A key lesson from history is that most irrigation-based civilizations fail. As we enter the third millennium A.D., the question is: will ours be any different?" Today, irrigation problems are widespread in the grain-growing regions of central and northern China, northwest and southern India, parts of Pakistan, much of the western United States, North Africa, the Middle East, and the Arabian Peninsula. Water tables are dropping steadily in several major food-producing regions as groundwater is pumped faster than nature replenishes it. The world's farmers are racking up an annual water deficit of some 160 billion cubic meters-the amount used to produce nearly 10 percent of the world's grain.
In addition to health and safety concerns, factory farms are also imposing a threat to the environment. Anders Nordgren claims in his article printed by the Journal of Agricultural and Environmental Ethics, “…since livestock production is an important contributing factor to climate change, we should undertake mitigation measures [… ] However, technological solutions do not seem sufficient in the livestock sector, leaving us with the option of reduced meat production and consumption.” (Nordgren, August 2012.) Harmful gases, such as methane, are being released because of irresponsible disposal of manure. These greenhouse gases released into the atmosphere are also contributing to climate change and global warming. Negligent disposal of manure also causes health and social problems.
The biggest threat to the environment is due to animal waste produce by factory farming. “According to data from the U.S. Department of Agriculture (USDA) and the EPA, animal feeding operations produce approximately 500 million tons of manure every year”( AN HSUS Report: The Impact of Industrialized Animal Agriculture on the Environment). Traditional farming operations that include the production of produce as well as livestock use the animal waste as fertilizer for crops, the high nitrogen levels help to boost plant growth. However industrial livestock companies must use other disposable methods due to the lack of land required for grassroots solution to animal waste. Instead corporations will haul to smaller nearby farming operations, the intense concentration of the manure in these agriculture areas cause high levels of harmful natural occurring chemicals found in animal waste end up in the water supply.
Sanitation isn’t just a problem in third world countries it’s a problem in most countries because of the bacteria and diseases that contaminates the water and the chemicals and waste dumped into water supplies. The world health organisation did an investigation into deaths by water borne diseases and effects of drinking dangerous chemicals mixed in with water every day. They figured out that annually 3.4 million people die just because of water borne diseases. The reason this death count is so high is because in most countries there sewage and water is untreated. Continents like North America and Europe have around 66% to 97% of their water and sewage treated in treatment plants although other continents like Asia, Africa and Oceana have 35%-0% of there water treated.

There is another critical cost paid immediately upon wastewater used to irrigate crops. About 7.4 percent of the nation, two third of land in Northern China, land is irrigated with polluted water, and definitely this reduces the amount of harvested crops, bad quality of crops, and devalued qualities of soils. Economic loss regarding crops is estimated about 61.3 billion yuan, about 0.46 percent of GDP, in 2003 (Xie, 2009, p 21). Water pollution also has a crucial effect on fishery industries.
Climate change is affecting agriculture by interfering with the efficiency of crop production. Agriculture is facing droughts, flooding, sea level elevations, natural disasters, and health hazards for employees. All of these exponents lead to crop failure that creates famines and food prices to rise. On the other side, agriculture is also contributing to climate change through their output of greenhouse gas emissions and carbon footprints. These are caused by the activities that agriculture engages with such as breeding of livestock, ploughing of fields, deforestation, and the use of pesticides and other agrochemicals.
Food wastage in the poor countries is due to lack of technology and infrastructure and result to as much as quarter of harvest getting lost (Global issues, 2010). According to Global issues (2010), world hunger results from poverty. World hunger is an issue of concern and continuous efforts should be made in order to save millions of people around the world. Solving the real cause of poverty is crucial towards permanently solving the world hunger problem. A study conducted by Food Agricultural Organization revealed that an approximated 1.3 billion tones of food is usually wasted every year (FAO 2011).
The Earth’s surface is covered by over two-thirds of water. With half of the world being covered by water; pollution in the water is a very big crisis that can actually be reduced to some extent. Water pollution is a human problem because it seems to be a recent development that started round the end of the 19th century. Scientists say that “humans have limits with an estimated 7 billion people on the planet, and pollution is a sign of exceeded pollution. According to the WWF (World Wildlife Fund) pollution is a serious problem.
To overcome this, China has a deal with the United Kingdom to trade pig semen for seventy eight million dollars (Brasch). Their livestock agriculture rapidly industrialized, causing harm to the environment in nearby communities, "[Since the pig farm opened], the air quality has deteriorated" stated an individual from the Hu Tong Luang village, twelve miles from the pork factory farm (The Guardian). This is due to lack of waste control that comes from the mass quantity of pigs. The waste pollutes ground water and causes many of the individuals who live near factory farms to fall ill (The Guardian). It only took a few decades for China to move from locally produce pork in backyards to full commercial factories.
Cattle Decapitation or Human Annihilation Do you know how factory farms affect your health, the world around you, and your children 's future? Factory farms are one of the major leading causes of pollution ,which causes a great amount of problems. The animals produced by the masses on these factory farms are extremely exploited and treated inhumanely. The methane from tons of animal manure is causing detrimental global warming. Global warming is affecting much more than the temperature, its damaging crops, species of animals are going extinct, and humans are having health problems.
