Nutrients are retained in the waste timber and livestock effluent and can be recycled within the farm system after use. Biogas plants are also able to use livestock manure to create biofuels, and these anaerobic digestion systems are known to capture methane in a usable form, while concentrating nitrogen, a valuable nutrient found in the manure ...
Examples of environmental impacts of animal agriculture: Meat production is a main driver of deforestation in Venezuela; Pigs in intensive farming; Testing Australian sheep for exhaled methane production to reduce greenhouse gas emissions from agriculture; Farms often pump their animal waste directly into a large lagoon, which has environmental ...
Waste can be transmitted to groundwater through the leaching of pollutants. [16] Some facility designs, such as lagoons, can reduce the risk of groundwater contamination, but the microbial pathogens from animal waste may still pollute surface and groundwater, harming wildlife and human health. [17]
There are many strategies to reduce greenhouse gas emissions from agriculture (this is one of the goals of climate-smart agriculture). Mitigation measures in the food system can be divided into four categories. These are demand-side changes, ecosystem protections, mitigation on farms, and mitigation in supply chains.
"Deli meat is unhealthy," Samantha Cassetty, a registered dietitian says. "It is a processed meat, and there is very good evidence that processed meat carries the risk of certain forms of cancer."

The United Nations writes that "intensification of animal production was seen as a way of providing food security."
Reducing meat consumption, without fully going vegan, is seen as a compromise, a slightly shameful cop-out. Many vegetarians harbor a lingering sense of guilt for not being vegan. The reducetarian ...
The second stage further separates the fat from the water. The solids may be used in food products, pet foods, etc., depending on the original materials. The separated fat may be used in food products, or if in surplus, may be diverted to soap making operations. Most edible rendering is done by meat packing or processing companies.
