Methane is a potent greenhouse gas with a global warming potential 25 times greater than carbon dioxide. It is primarily emitted from the digestive systems of ruminant animals, such as cattle, sheep, and goats, during the process of enteric fermentation.

Beef production has the highest environmental impact due to the large amount of land, water, and feed required to raise cattle. It also generates significant amounts of greenhouse gases and contributes to deforestation.

Meat production is responsible for approximately 14-18% of global greenhouse gas emissions, making it a significant contributor to climate change.

Meat production occupies approximately 35-40% of the world's land surface, including grazing land, feed crop cultivation, and infrastructure.

Cattle ranching is the leading cause of deforestation in many parts of the world, as large areas of forest are cleared to create grazing land for cattle.

Intensive livestock farming can lead to water pollution from animal waste runoff, air pollution from ammonia emissions, and soil degradation due to overgrazing and nutrient depletion.

Factory farming, intensive livestock farming, and concentrated animal feeding operations (CAFOs) all refer to the practice of raising animals for food in a confined, indoor environment.

Reducing meat consumption can lead to reduced greenhouse gas emissions, improved water quality, and reduced deforestation, among other benefits.

Veganism is a diet that excludes all animal products, including meat, dairy, eggs, and honey.

The production of animal feed can lead to water pollution from fertilizer runoff, air pollution from ammonia emissions, and soil degradation due to intensive farming practices.

Organic farming, sustainable agriculture, and agroecology are all terms used to describe the practice of raising animals for food in a more sustainable and environmentally friendly manner.

Adopting a more plant-based diet can lead to a reduced risk of chronic diseases, improved gut health, a lower carbon footprint, and other health and environmental benefits.

Flexitarianism is a diet that emphasizes plant-based foods but occasionally includes meat or fish.

The transportation of meat and animal products can lead to greenhouse gas emissions, air pollution from vehicle exhaust, and water pollution from runoff containing animal waste.

Aquaculture, mariculture, and pisciculture are all terms used to describe the practice of raising fish for food in a controlled environment.
