How does agriculture affect human health?
In some respects there has been improvement in the health and safety of those working in agriculture due to improved technology, personal protection, and awareness of hazards.
What are the factors that affect agricultural workers?
Health studies must consider several modifying factors in agricultural exposures resulting in physical illnesses including work force age and ethnicity, type of commodity, work practices, engineering controls, and use of personal protective equipment. The work force has significantly changed and varies greatly by region. Principle operators tend to be Caucasian and older. There has been a slight increase in women principle operators. There has also been an increase in principle operators that work off the farm, which adds additional exposure issues (US Census of Agriculture, 1997). Hired farm workers are increasingly foreign born, younger males. It is thought that agriculture is now at a low point in agricultural labor and as the number of farms decrease, there will be an increase in the size of the agricultural labor force. According to the 1997 USDA Agricultural census the average age of principle operators is 54.3 years. Aging of the farm population may lead to increased susceptibility to the adverse effects of occupational exposures, on chronic diseases including respiratory and musculoskeletal illnesses. Many hired farm workers no longer have an agricultural background and use employment in the agricultural sector as an entry-level job. A language barrier exists which can impede following safety information on labels and training in proper work practices. Farm labor contractors instead of farm owners now hire large numbers of farm workers, raising new health and safety concerns. All of these changes may increase health and safety hazards in the agricultural workplace. Perhaps the hallmark of agricultural exposures is their enormous diversity in type, as well as in dose and duration. The ethnic variation in the agricultural workforce compounds the potential health hazards.

Why are trees being cut down in the Amazon rainforest?
And agriculture is currently the leading cause of habitat destruction. Globally trees are being cut down, the land is turned into field to grow crops and raise livestock. For the local communities this can be positive, providing more jobs for local people and improving the local economy. However, this does come at a price, agriculture is the leading cause of Amazon rainforest destruction, accounting for 91% of trees cut down so far. As of 2016, half of the world rainforest have been cleared, some of this destruction is due to logging companies cutting down trees, however large areas of trees are cut down to prepare the land for animal grazing. Trees absorb harmful greenhouse gases, they store large amounts of CO2, consequently when large areas of trees are cut down huge levels of CO2 are released back into the atmosphere. Furthermore, due to huge amounts of trees being cut down in rainforests around the world everyday habitats are destroyed. Consequently, the homes of species that reside in these areas are eradicated, which has led to the extinction of many
How does agriculture affect the environment?
One of the most troubling environmental disadvantages to industrial agriculture is its contributions to climate change. Globally, agriculture is one of the largest drivers of anthropogenic climate change, accounting for around twelve percent of total emissions, and nearly a quarter of greenhouse gas emissions. Industrial crop production hampers the ability of soil to act as a carbon sequester, ultimately turning it into a carbon emitter. Animal agriculture (most of which is raised intensively) accounts for large amounts of greenhouse gas emissions, including 37% of all methane emissions and 65% of nitrous oxide.
Why are chemicals used in agriculture?
Chemical hormones are often used in industrial agriculture in order to maximize yields. One of the most well-known is Bovine somatotropin, or bovine growth hormone, which is used to increase milk production in lactating cows. Although approved by the FDA, the hormone has been linked with increased instances of infections, lameness and other ailments in cows, and potentially to cancer development and other disorders in humans.
What is monocropping in agriculture?
Monocropping is a defining feature of intensive plant agriculture. Large areas of land are planted with a single species, such as wheat, corn, or soy, with the latter two used heavily in animal feed. The use of synthetic fertilizers allow crops to be grown year after year on soil that becomes more depleted as time goes on; because time is money, fields are not allowed to go fallow, which would allow the soil to naturally replenish the nutrients plants require.
Why are intensive agriculture corporations vertically integrated?
In the United States, intensive agriculture corporations tend to be vertically integrated, freeing them from setting prices for their products that are determined by supply and demand , such as traditional farmers are forced to. This enables intensive operations to undercut smaller farms and eventually force them out of the market. Combined with the significant financial and political cloud multinational agricultural corporations have, fewer traditional farmers than ever are able to compete.
How can intensive agriculture be sustainable?
However, one of the most effective and immediate steps that can be taken towards sustainability is for people to curtail the consumption of animal products since these are the most polluting, resource-intensive, and cruelest forms of agriculture. Particularly those in wealthy nations like the United States and New Zealand – two of the highest per-capita consumers of meat – ought to decrease animal product consumption, since consuming animal products can produce negative health outcomes like cardiovascular disease.
What is extensive agriculture?
Intensive and extensive agriculture stands in opposition to one another in many ways. Extensive farming refers to systems that use relatively small amounts of inputs, such as human labor, machinery such as tractors, and investment. Fewer inputs are needed to produce yields, since extensive agriculture tends to make use of naturally-occurring resources, such as fertile soil. Pastoral production, where animals are grazed outdoors for their entire lives or are tended to by nomadic farmers – is a type of extensive agriculture, as are operations that favor greater plant and crop diversity.

How has agriculture increased?
Agricultural methods have intensified continuously ever since the Industrial Revolution, and even more so since the “green revolution” in the middle decades of the 20 th century. At each stage, innovations in farming techniques brought about huge increases in crop yields by area of arable land. This tremendous rise in food production has sustained a global population that has quadrupled in size over the span of one century. As the human population continues to grow, so too has the amount of space dedicated to feeding it. According to World Bank figures, in 2016, more than 700 million hectares (1.7 billion acres) were devoted to growing corn, wheat, rice, and other staple cereal grains—nearly half of all cultivated land on the planet.

How much of the world’s freshwater is consumed by agriculture?
Worldwide, agriculture accounts for 70 percent of human freshwater consumption. A great deal of this water is redirected onto cropland through irrigation schemes of varying kinds. Experts predict that to keep a growing population fed, water extraction may increase an additional 15 percent or more by 2050. Irrigation supports the large harvest yields that such a large population demands. Many of the world’s most productive agricultural regions, from California’s Central Valley to Southern Europe’s arid Mediterranean basin, have become economically dependent on heavy irrigation.
What causes algae blooms in China?
Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere.
