Impact of Livestock on Climate Change Livestock

Impact of Livestock on Climate Change Livestock

• Livestock and livestock-related activities such as deforestation and increasingly fuel-intensive farming practices are responsible for over 18% of human-made greenhouse gas emissions, including →
• 9% of global carbon dioxide emissions
• 35–40% of global methane emissions (chiefly due to enteric fermentation and manure)
• 64% of global nitrous oxide emissions (chiefly due to fertilizer use.)

• Livestock activities also contribute disproportionately to land-use effects, since crops such as corn and alfalfa are cultivated in order to feed the animals.
• In 2010, Enteric Fermentation accounted for 43% of the total greenhouse gas emissions from all agricultural activity in the world.
• The meat from ruminants has a higher carbon equivalent footprint than other meats or vegetarian sources of protein.
• Methane production by animals, principally ruminants, is estimated 15-20% global production of methane.
• Worldwide, livestock production occupies 70% of all land used for agriculture, or 30% of the land surface of the Earth. The way livestock is grazed also affects future fertility of the land.

Recirculating aquaculture system Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. The main benefit of RAS is the ability to reduce the need for fresh, clean water while still maintaining a healthy environment for fish. RAS can be a viable form of intensive Aquaculture
