A 2017 meta-study of the scientific literature estimated that the total global soil carbon sequestration potential from grazing management ranges from 0.3–0.8 gigatons CO 2 eq per year, which is equivalent to 4–11% of total global livestock emissions, but that "Expansion or intensification in the grazing sector as an approach to ...
On mixed grass prairies, experimental local warming of 1.5 °C (2.7 °F) during the day and of 3 °C (5.4 °F) at night has a relatively minor effect in comparison to increasing CO 2 levels to 600 ppm (nearly 50% larger than the ~420 ppm levels of 2023) during the same experiment. 96% of overall forage growth on such prairies stems from just ...
A few ways to reduce methane emissions include switching to plant-rich diets with less meat, feeding the cattle more nutritious food, manure management, and composting. [ 72 ] Traditional rice cultivation is the second biggest agricultural methane source after livestock , with a near-term warming impact equivalent to the carbon dioxide ...

The Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT) is a UK independent scientific committee that provides advice to the Food Standards Agency, the Department of Health and other government departments and agencies on matters concerning the toxicity of chemicals.
Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.
This is accomplished by heating the material to above 825 °C (1,517 °F), [6] [7] a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO 2), leaving quicklime behind. This is also one of the few chemical reactions known in prehistoric times. [8] CaCO 3 (s) → CaO(s) + CO 2 (g)
All products made by Bassar were recalled on the 7th of September. [113] 2024 – Applesauce products containing cinnamon were found to contain lead chromate, leading to reports of child lead poisoning across the United States. The source of the adulteration was the cinnamon, which was thought to have been adulterated to enhance its weight or ...
