What is the result of eutrophication?

The result may be eutrophication, an excessive amount of nutrients in a body of water resulting in a substantial growth of plants, such as algae, and a lack of oxygen in the water because of this increase in plants. There is a finite amount of land on the planet, and agricultural practices take up a lot of land.


Where do fertilizers end up?

Fertilizers, while a nutrient for some plants, end up in streams and lakes in amounts higher than would occur naturally.


Does soil degrade over time?

Thus, the soil degrades over time. If we’re in areas with heavy rainfall, replacing forests with cropland often results in an increase in flooding. Another problem has to do with the amount of water some crops require. Agriculture is the industry with the largest water consumption.


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.


What is the impact of livestock on the environment?

Agricultural livestock are responsible for a large proportion of global greenhouse gas emissions, most notably methane. In addition, overgrazing is a major problem regarding environmental sustainability. In some places, stretches of forage land are consumed so extensively that grasses are unable to regenerate.


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. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive.


What are the causes of the pollution of the soil?

The excess levels of nitrogen and phosphorus have caused the once-beneficial nutrients to become pollutants. Roughly half the nitrogen in synthetic fertilizers escapes from the fields where it is applied, finding its way into the soil, air, water, and rainfall.


How does nitrogen affect the environment?

While these chemicals have helped double the rate of food production, they have also helped bring about a gigantic increase, perhaps as high as 600 percent, of reactive nitrogen levels throughout the environment. The excess levels of nitrogen and phosphorus have caused the once-beneficial nutrients to become pollutants. Roughly half the nitrogen in synthetic fertilizers escapes from the fields where it is applied, finding its way into the soil, air, water, and rainfall. After soil bacteria convert fertilizer nitrogen into nitrates, rainstorms or irrigation systems carry these toxins into groundwater and river systems. Accumulated nitrogen and phosphorus harm terrestrial and aquatic ecosystems by loading them with too many nutrients, a process known as eutrophication. Nutrient pollution is a causal factor in toxic algae blooms affecting lakes in China, the United States, and elsewhere. As excessive amounts of organic matter decompose in aquatic environments, they can bring about oxygen depletion and create “dead zones” within bodies of water, where nothing can survive. Parts of the Gulf of Mexico are regularly afflicted in this manner. Nitrogen accumulation in water and on land threatens biodiversity and the health of native plant species and natural habitats. In addition, fertilizer application in soil leads to the formation and release of nitrous oxide, one of the most harmful greenhouse gases.

Methane, according to the Food and Agriculture Organization (FAO), is the most emitted gas in animal agriculture, accounting for around 40 percent of the sector’s emissions.


What happens when the weather changes?

Rising temperatures disrupt weather patterns, which yield excessive weed overgrowths, increased plant diseases, and insect infestations. Increased rain leads to flooding which has the potential to drown scores of crops, while on the opposite end, reduced water supply in certain areas can parch them.


What are the causes of food scarcity?

Droughts are not the only causes of food scarcity. Animal agriculture is a leading cause of land degradation, resource use, and deforestation, three major contributors to climate change. A changing climate produces extreme weather events, water scarcity, rising sea levels, and other events that reduce food outputs.


What happens to animals when the climate is warm?

A warming climate can disrupt the delicate balance of reproductive cycles, migration patterns, and food routines for animals. Warmer weather and increased rainfall means certain insects, like mosquitoes, have extended breeding periods.

The vector control programmes and modern industrial agricultural practicesfor public health purposes use chemical insecticides and pesticides to control disease carriers and insect pests.


What is corporate farming?

The term corporate farming encompasses the production of animal and plant foods as well as the transportation for marketing. The “farmers” are actually large corporations who are absentee farmers and have no stake in the surrounding environment. It first began with chickens because they were easily housed in small spaces.


Why do corporate farms inject animals with drugs?

For this reason, corporate farms inject the livestock with drugs to prevent any disease taking hold as soon as they are acquired. Giving livestock drugs, they don’t need leads to the breeding of drug resistant bacteria and some of these can be passed from livestock to humans.


Why do livestock produce growth hormones?

The livestock are usually given growth hormones to up the production of meat. These drugs and hormones are passed from the livestock in their bodily waste and to humans in the meat or by-products of the animal. We know this because the manure of close confinement livestock has a higher level of heavy metals, arsenic, antibodies and pathogens than those raised in the traditional way.


Is the ocean unfit for human consumption?

Not only is the water unfit for human consumption, it is now destroying the marine ecosystem and this is serious business when you consider how important the ocean’s health is to human survival. The level of mercury found in tuna and salmon has already resulted in warnings about how much to consume because it is threatening to our very life.


How does livestock waste get into the ocean?

Chemical insecticides and fertilizers have been leaching into our waterways for years. So has the livestock waste stored in lagoons by corporate farmers, some of which are as large as 200 acres. Once these have entered the ground, they will eventually enter our drinking water and all the streams and rivers that lead to the ocean.


Do animals graze in open pastures?

Animals raised on family owned farms are allowed to graze in open pastures and are not injected with growth hormones or given drugs to prevent every disease known to man. Sick livestock is disposed of and never enters the food chain and their waste is spread over a larger area, which allows nature to dispose of it in a natural way.


How does land use affect climate?

Land‐cover changes are responsible for surface and vegetation modifications what reflects in surface albedo and thus surface‐atmosphere energy exchanges , which have an impact on regional climate. Terrestrial ecosystems are important sources and sinks of carbon and thus land‐use changes reflect also in the carbon cycle. The important contribution of local evapotranspiration to the water cycle—that is precipitation recycling—as a function of land cover highlighted yet another considerable impact of land‐use/cover change on climate, at a local to regional scale [ 50 ].


Why is agriculture important?

For many economies, especially those of developing countries, agriculture can be an important engine—driving force—of economic growth . Approximately three‐quarters of the world’s agricultural value added is generated in developing countries where agriculture constitutes the backbone of the economy. But not only in the developing countries but also in the developed countries agriculture has always been the precursor to the rise of industry and services [ 8 ].


How did cropland expansion affect agriculture?

The mix of cropland expansion and agricultural intensification has varied geographically. Tropical Asia increased its food production mainly by increasing fertilizer use and irrigation. Most of Africa and Latin America increased their food production through both agricultural intensification and extensification. In western Africa cropland expansion was accompanied by a decrease in fertilizer use and a slight increase in irrigation [ 18 ]. Agriculture is the single largest user of freshwater resources, using a global average of 70% of all surface water supplies.


What are the driving forces of agriculture?

Agricultural ecosystems are interlinked with rural areas where more than 3 billion people live, almost half of the world’s population. Roughly 2.5 billion of these rural people derive their livelihoods from agriculture. Thus, population and land‐use trends are considered to be the main driving forces for agriculture. Besides these driving forces, EEA [ 7] further distinguished the so‐called external and internal driving forces originating from market trends, technological and social changes, as well as the policy framework.


How does land use affect biodiversity?

Land use, specifically in agriculture, has great impact on biodiversity. Another aspect contributing to biodiversity decline is that humans today depend for survival on tiny fraction of wild species that has been domesticated. Yet only 14 of 148 species weighing 45 kg or more were actually domesticated. Similarly, worldwide there are about 200,000 wild species of higher plants, of which only about 100 yielded valuable domesticates [ 53 ].


How has agriculture changed over the past 50 years?

Agriculture in the last century has evolved from self‐sufficiency to surplus in some parts of the world. Thus, transformation was connected with intensification and specialization of production as main trends in European or North American agriculture accompanied by negative impact on the environment. Agricultural intensification is defined as higher levels of inputs and increased output of cultivated or reared products per unit area and time [ 27 ]. Over the past 50 years, agricultural production has grown between 2.5 and 3 times, thanks to significant increase in the yield of major crops [ 14 ]. Changing land‐use practices have enabled world grain harvests to double from 1.2 to 2.5 billion tonnes per year between 1970 and 2010. Globally, since 1970, there has been a 1.4‐fold increase in the numbers of cattle and buffalo, sheep and goats, and increases of 1.6‐ and 3.7‐fold for pigs and poultry, respectively [ 28 ].


How does human activity affect land use?

Land cover and land‐use patterns on Earth reflect the interaction of human activities and the natural environment [ 1 ]. Human population growth together with competitive land use causes land scarcity, conversion of wild lands to agriculture and other uses. As we can see, the anthropogenic factor has an important impact on land use and land cover changes. Given this human influence, especially during the past 100 years, the recent period has been called the Anthropocene Age [ 2 ]. Human influence on the land and other natural resources is accelerating because of rapid population growth and increasing food requirements. The increasing agricultural intensity generates pressure not only on land resources but also across the whole environment. These factors make agriculture a top‐priority sector for both economic and environmental policy.
