What are the negative impacts to an ecosystem of intensive livestock production?

What are the negative impacts of intensive livestock production?

Intensive feed-crop production can lead to severe land degradation, water pollution and biodiversity losses, while expanding arable land into natural ecosystems often has serious ecological consequences, including the loss of biodiversity and of ecosystem services such as water regulation and erosion control.

What are the negative effects of livestock?

Cattle are frequently cited as having the most severe overall environmental impacts among livestock species due to: methane and nitrous oxide released from digestion and manure; land use and conversion; desertification; inefficient ratio of weight of feed and water consumed to weight of meat and dairy produced; …

How does intensive animal farming affect the environment?

Intensive livestock farming generates secondary particulate matter (PM) formation, especially ammonium nitrate as a consequence of ammonia (NH3) emissions from animal manure and urine, and has been estimated to have a substantial impact on air quality (11). … Almost all NH3 emissions result from agricultural activities.

How does livestock affect the environment?

The livestock sector contributes 14.5% of global GHG emissions (Gerber et al., 2013), and thus may increase land degradation, air and water pollution, and declines in biodiversity (Bellarby et al., 2013, Reynolds et al., 2010, Steinfeld et al., 2006, Thornton and Gerber, 2010).

What are five environmental dangers to people working with livestock?

A new report from FAO says livestock production contributes to the world’s most pressing environmental problems, including global warming, land degradation, air and water pollution, and loss of biodiversity.

What does livestock production affect?

Examples of the possible environmental effects on air are emissions of ammonia (which can lead to acidification and, after subsequent deposition, to eutrophication), the greenhouse gases methane and nitrous oxide, odours and particulates.

How does livestock affect global warming?

Livestock are responsible for 14.5 percent of global greenhouse gases. India, for example, has the world’s largest cattle population, but the lowest beef consumption of any country. As a result, cows live longer and emit more methane over their lifetime.

How does Livestock Affect Economy?

Livestock contribute 40 percent of the global value of agricultural output and support the livelihoods and food security of almost a billion people. The livestock sector is one of the fastest growing parts of the agricultural economy, driven by income growth and supported by technological and structural change.

Is livestock production bad for the environment?

Livestock emit almost 64% of total ammonia emissions, contributing significantly to acid rain and to acidification of ecosystems. Livestock are also a highly significant source of methane emissions, contributing 35–40% of methane emissions worldwide.

How does the industrial livestock system affect deforestation?

Worldwide, deforestation due to cattle ranching releases 340 million tons of carbon into the atmosphere each year, or 3.4 percent of global greenhouse gas emissions. Most of this comes from the Amazon region. In 2009, Greenpeace published a landmark three-year investigation entitled Slaughtering the Amazon.
