Message definition (Greenhouse gas emissions from agriculture)

=== Methane emissions ===
[[File:Methane-emissions-agriculture (OWID 0666).png|thumb|Methane emissions from agriculture, 2019. Methane (CHa) emissions are measured in tonnes of carbon dioxide-equivalents]]
[[File:The Global Methane Budget 2008–2017.png|thumb|Global methane budget.]][[Methane emissions]] from livestock are the number one contributor to agricultural greenhouse gases globally. Livestock are responsible for 14.5% of total anthropogenic greenhouse gas emissions. One cow alone will emit 220 pounds of methane per year. While the [[residence time]] of methane is much shorter than that of carbon dioxide, it is 28 times more capable of trapping heat. Not only do livestock contribute to harmful emissions, but they also require a lot of land and may [[Overgrazing|overgraze]], which leads to unhealthy soil quality and reduced species diversity. 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 [[compost]]ing.

メタン排出量

畜産からのメタン排出量は、世界的に農業温室効果ガスの最大の寄与源である。畜産は人間活動による温室効果ガス総排出量の14.5%を占める。牛1頭だけでも年間220ポンドのメタンを排出する。メタンの滞留時間は二酸化炭素よりもはるかに短いものの、熱を閉じ込める能力は28倍も高い。畜産は有害な排出に寄与するだけでなく、多くの土地を必要とし、過放牧につながり、それが土壌の質の低下や種多様性の減少を引き起こす可能性がある。メタン排出量を削減するには、肉の少ない植物中心の食事への切り替え、家畜により栄養価の高い飼料を与えること、糞尿管理、そして堆肥化などが挙げられる。
