Significance Livestock-based food production is an important and pervasive way humans impact the environment. It causes about one-fifth of global greenhouse gas emissions, key land user source water pollution by nutrient overabundance. also competes with biodiversity, promotes species extinctions. Empowering consumers to make choices that mitigate some these impacts through devising disseminating numerically sound information thus a socioenvironmental priority. Unfortunately, currently...
Significance With a third of all food production lost via leaky supply chains or spoilage, loss is key contributor to global insecurity. Demand for resource-intensive animal-based further limits availability. In this paper, we show that plant-based replacements each the major animal categories in United States (beef, pork, dairy, poultry, and eggs) can produce twofold 20-fold more nutritionally similar per unit cropland. Replacing items with replacement diets add enough feed 350 million...
Significance The cultivation of microbial biomass, which is rich in proteins as well other nutrients, can play a vital role achieving food security while mitigating the negative environmental footprint agriculture. Here, we analyze efficiency associated with using solar energy for converting atmospheric CO 2 derived from direct air capture into biomass that feed humans and animals. We show production foods outperforms agricultural staple crops terms caloric protein yields per land area at...
Inadequate micronutrient intakes and related deficiencies are a major challenge to global public health. Analyses over the past 10 years have assessed inadequate nutrient supplies, but there been no estimates of intakes. We aimed estimate prevalence for 15 essential micronutrients identify dietary gaps in specific demographic groups countries.
Feeding a growing population while minimizing environmental degradation is global challenge requiring thoroughly rethinking food production and consumption. Dietary choices control availability natural resource demands. In particular, reducing or avoiding consumption of low efficiency animal-based products can spare resources that then yield more food. quantifying the potential gains specific dietary shifts, most earlier research focused on calories, with less attention to other important...
Rising inequalities and accelerating global environmental change pose two of the most pressing challenges twenty-first century. To explore how these phenomena are linked, we apply a social-ecological systems perspective review literature to identify six different types interactions (or “pathways”) between inequality biosphere. We find that research so far has only considered one-directional effects on biosphere, or vice versa. However, given potential for complex dynamics socioeconomic...
Abstract Reducing food waste is widely recognized as critical for improving resource efficiency and meeting the nutritional demand of a growing human population. Here we explore whether sharing economy can provide meaningful assistance to reducing in relatively low-impact environmentally-sound way. Analyzing 170,000 postings on popular peer-to-peer food-sharing app, find that over 19 months, 90t with an equivalent retail value £0.7 million were collected by secondary consumers diverted from...
A key aim of sustainable development is the joint achievement prosperity, equality, and environmental integrity: in other words, material living standards that are high, broadly-distributed, low-impact. This has often been called "triple bottom line". But instead, what if there a "trilemma" inhibits simultaneous these three goals? We analysed international patterns trends relationships between per-capita gross national income, Gini coefficient for income distribution, ecological footprint...
Abstract Because meat is more resource intensive than vegetal protein sources, replacing it with efficient plant alternatives potentially desirable, provided these prove nutritionally sound. We show that conserving to rigorously satisfy key nutritional constraints while minimizing cropland, nitrogen fertilizer (Nr) and water use greenhouse gas (GHG) emissions exist, could improve public health. develop a new methodology for identifying whose satisfaction by eaters challenging,...
Access to high-quality dietary intake data is central many nutrition, epidemiology, economic, environmental, and policy applications. When on individual nutrient intakes are available, they have not been consistently disaggregated by sex age groups, their parameters full distributions often publicly available.
Omega-3 EPA and DHA fatty acids are vital for human health, but current nutritional requirements greater than supply. This nutrient gap is poised to increase as demand increases the abundance of aquatic foods amount omega-3 they contain may dwindle due climate change overfishing. Identifying mitigating loss inefficiencies across global supply chain has great potential narrowing this gap. Here, using an optimization model, we show that humans could potentially by much 50% (reaching 630 kt...
The high resource intensity of industrial beef in high-income economies has prompted growing interest alternative, potentially lower environmental impact production pathways. Of those, grass feeding is promoted by some as one such but rigorous quantification this claim required. Motivated to bridge knowledge gap, we integrate empirical evidence with a model based on authoritative equations governing cattle performance quantify the greenhouse gas emissions producing grass-fed beef. Because...
Livestock farming incurs large and varied environmental burdens, dominated by beef. Replacing beef with resource efficient alternatives is thus potentially beneficial, but may conflict nutritional considerations. Here we show that protein-equivalent plant based to the portion of mean American diet are readily devisible, offer mostly improved profile considering full lipid profile, key vitamins, minerals, micronutrients. We then replacement diets require on average only 10% land, 4%...
SUMMARY The high environmental costs of raising livestock are now widely appreciated, yet consumption animal-based food items continues and is expanding throughout the world. Consumers' ability to distinguish among, rank, various interchangeable crucial reducing diets. However, individual burdens exerted by five dominant categories – beef, dairy, poultry, pork eggs not fully known. Quantifying those requires splitting livestock‘s relatively well-known total (e.g. land fertilizer use for feed...
We present results of the deposition nitrogen compounds formed from lightning (LNO x ) using global chemical transport Model Atmospheric Transport and Chemistry–Max Planck Institute for Chemistry version. The model indicates an approximately equal LNO in both terrestrial oceanic ecosystems, primarily tropics midlatitudes open ocean, despite much higher intensities flashes above landmasses. highest values are due to wet convective deposition, with concentrated tropical continents....
