How Much Beef Is 82.5 Pounds
October 2020
When ruminant animals such as goats, sheep, and especially cattle digest their food, it gets processed in their systems by way of fermentation. This process breaks the food down over time and produces methane, a powerful greenhouse gas that contributes to our speedily warming planet when expelled to the atmosphere in the traditional biologic routes; i.east., flatulence or burps. Researchers accept plant that 37% of methane emissions from human activity are the direct issue of our livestock and agricultural practices.
The problem becomes more than apparent because the sheer scale of livestock raised for meat production throughout the world. A single cow produces between 154 to 264 pounds of methane gas per year. Non counting for the emissions of whatsoever other livestock, 1.5 billion cattle, raised specifically for meat product worldwide, emit at least 231 billion pounds of marsh gas into the methyl hydride into the atmosphere each twelvemonth (Our World in Data). Because methane is such a stiff greenhouse gas (come across Box), in that location is not bad interest in curbing its production. A number of companies and start-ups are investing in establish-based products that mimic meat's flavor and and texture, while others focus on lab-grown alternatives, both of which would lessen the demand for animal farms and their associated emissions if more than widely adopted.
The hunt is already on to investigate whether like results tin can be produced from aquaculture products in animate being feed with a blazon of scarlet seaweed, Asparagopsis taxiformis, showing the most promise. This seemingly innocuous plant could one mean solar day lower marsh gas emissions by as much as 98% in cattle with only a 0.20 percentage add-on to that animal'south feed per day. While non as efficient, other aquaculture products such as Asparagopsis armata, native to the Northeastern Atlantic and Mediterranean Sea, accept been shown to be constructive in dairy cows, reducing their methane emissions by 67% with only a ane% seaweed mix. Although results are promising, scaling up production as a widely bachelor feed additive is still in the developing stages, equally is the ability to introduce and market these products. Even so, the aquaculture industry is well-positioned to enter this innovative field in a way that volition one solar day provide local and global benefits by offer a reproducible emissions reduction technology at an affordable price. Regional aquaculture ventures – based on regional availability of effective seaweed varieties – could become local sources of feed additive, supporting local economies worldwide and keeping production costs low.
Aquaculture'southward potential goes well beyond fauna feed, especially in the Southeast New England Programme (SNEP) region where it is nonetheless a nascent manufacture reliant on oysters for greatest economic value. According to the Massachusetts Aquaculture Association, aquaculture ranks fifth in value of all agricultural products and is among the land's fastest growing agricultural sectors, with oyster farming alone ranking third in value of all landed seafood in Massachusetts. Across their value as nutrient, shellfish (primarily oysters) are also seen equally a low-tech nitrogen reduction intervention for waterbodies impaired by nutrients. Although the connected efficacy of this application is however beingness quantified, oyster reefs have a demonstrated upshot on water quality, filtering up to 50 gallons of h2o per oyster per day. Oysters can remove nitrogen
(stored in their tissue and shells) and promote college denitrification in the sediment. Oyster reefs also promote biodiversity by serving as shelters for thousands of species. In an ongoing SNEP-funded project, a squad at UMass Dartmouth has been determining baseline weather at Cockeast Pond – a saltwater pond with a loftier level of nitrogen enrichment – in society to measure out the total potential restorative impacts of newly deployed oyster populations. After compiling nigh a decade'southward-worth of data, the team plans to employ their technique for water quality restoration via oyster aquaculture to several areas along the Westport River.
In the Town of Orleans, oyster aquaculture is being used equally a nitrogen reduction approach in Lonnie'due south Pond, where excess nitrogen has impaired the water and habitat. Aquaculture at this site will aid the town meet the goal of reducing roughly 660 pounds of Nitrogen per year (lbs-N/yr) as part of the town'southward overall Nitrogen Management Program. Partnered with Ward AquaFarms, the town deployed approximately 1.five meg oysters into Lonnie's Pond in 2019 with the goal of removing 165 lbs-North/twelvemonth through oyster farming, constituting 25% nitrogen removal of the total 660 lbs-Due north/yr target. The oysters were deployed in mid-July and harvested in Dec. The total net removal was 136 lbs-North, fulfilling 82.five% of the goal. Previous years showed that longer deployments tin increase nitrogen removal, therefore future considerations should include increasing the deployment time by deploying before.
Every bit these industries go on to develop throughout the SNEP region, at that place are additional opportunities to innovate. For aquaculture oysters, questions remain as to how much of an increment in supply the wild oyster market tin can absorb without seeing an equal increase in need. Although the potential benefits of oystering are large, new uses for the increased supply will be required to allow the aquaculture industry to continue its expansion. One potential avenue could include their sale as nutrient-rich fertilizers, which could negate some of the need for new fertilizers currently being brought into the region. Throughout Cape Cod, fertilizer utilize is the 2nd highest controllable source of food pollution in coastal embayments (Cape Cod Committee).
In aquaculture production, multi-crop ventures that cultivate oysters, salmon, and kelp inside the same area in a closed-loop production procedure are known as Integrated Multi-Trophic Aquaculture (IMTA); species grown in this system crave nil inputs (no fertilizers) and do good from cohabitation of other species within the arrangement. The presence of kelp provides habitat and shelter for fish and shellfish, whose excrement and so nurtures the kelp. In improver, IMTA allows for increased food removal, as seaweed can sequester 5 times more carbon than land plants and uses dissolved inorganic nitrogen to abound. Studies from the Lindell Lab at Woods Pigsty Institution of Oceanography have shown that a multi-ingather farming of seaweed in conjunction with oysters can remove more nitrogen from impaired waters than a traditional mono-ingather venture alone. This innovative aquaculture concept can assist to rebuild ecosystems and tin be used to restore nutrient impaired waters, while as well creating a lucrative industry for famers in the expanse without requiring much boosted infinite.
The potential to aggrandize aquaculture throughout the SNEP region is pregnant. with numerous designs to emulate and markets to tap. Benefits abound from improving regional water quality, to supporting agronomical ventures while simultaneously reducing powerful greenhouse gases emitted from livestock or strengthening local economies in the sale of aquaculture products. Not to mention the knock-on benefits associated with cleaner h2o and air. Aquaculture is a nascent manufacture that deserves farther research and local investment – this is just the start.
