Why is agriculture bad for climate change?
Dominant sources of agricultural greenhouse gases (GHGs) include carbon dioxide (CO2) from tropical deforestation, methane (CH4) from livestock and rice production, and nitrous oxide (N2O) from fertilizing or burning croplands. Agriculture is responsible for about half of global methane emissions.
How agriculture causes global warming?

According to a study by WWF, sugar is among the crops most harmful to the planet. By replacing habitats rich in animal, plant and insect life, sugar plantations destroy the most biodiversity in the world.
How does agriculture affect the world?
Agricultural livestock are responsible for a large proportion of global greenhouse gas emissions, most notably methane. In addition, overgrazing is a major problem regarding environmental sustainability. In some places, stretches of forage land are consumed so extensively that grasses are unable to regenerate.
