Human activities contribute significantly to climate change through the release of greenhouse gases into the atmosphere. The burning of fossil fuels, such as coal, oil, and natural gas, for energy production is a major source of carbon dioxide (CO2) emissions. Deforestation also plays a role, as trees absorb CO2, and their removal reduces the planet's capacity to offset these emissions.
Additionally, industrial processes release other potent greenhouse gases like methane (CH4) and nitrous oxide (N2O). Agricultural practices, such as rice cultivation and livestock farming, contribute to methane emissions, while the use of nitrogen-based fertilizers releases nitrous oxide.
Fossil Fuels:
Humans contribute to climate change through the burning of fossil fuels. Fossil fuels, such as coal, oil, and natural gas, release carbon dioxide (CO2) and other greenhouse gases when burned for energy. The combustion of these fuels in power plants, vehicles, and industrial processes adds substantial amounts of CO2 to the atmosphere, enhancing the greenhouse effect.
The greenhouse gases trap heat in the Earth's atmosphere, leading to a warming effect known as global warming. e

Deforestation:
. Trees act as crucial carbon sinks, absorbing CO2 during photosynthesis. However, when forests are cleared for purposes like agriculture, logging, or urbanization, this stored carbon is released back into the atmosphere as CO2, intensifying the greenhouse effect. Furthermore, the loss of trees reduces the planet's overall ability to regulate climate and exacerbates global warming. The impact of deforestation on climate change underscores the importance of conservation and sustainable land-use practices to mitigate these detrimental effects.

Farming:
Methane, a strong greenhouse gas released during the digestion of ruminant animals like cattle, is the main way that livestock production by humans contributes to climate change. Enteric fermentation is a naturally occurring digestive process that produces methane, especially in cows. These creatures belch to release methane into the atmosphere, a result of the bacteria in their stomachs breaking down fibrous plant sources. These emissions are increased by the methods of livestock husbandry, particularly in concentrated animal feeding operations (CAFOs). .
