A major international study concluded on Wednesday that the global methane gas emission rose by 9% – a majority of which is man-made, and in that majority, livestock contributes the greatest.
Methane or CH4 also occurs naturally, but as per the study, 60% of the current CH4 emission is now manmade. The deadly gas is a major greenhouse contributor and is 20-times more potent than Carbon Dioxide (CO2) in global warming in a 100-years period, Agence France Presse reports.
Of the sixty percent man-made methane in atmosphere, 30% comes from the digestive system of cattle and sheep, grown in billions every year for human consumption. 20% comes from burning the fossil fuels and 11% from coal mine leaks, the study says.
The researchers have identified three main sources of the present era methane contributor and all of them are manmade – livestock rearing, burning of fossil fuel, and waste management. It must be noted that methane occurs naturally in the atmosphere in wetlands and lakes.
The study noted methane concentration in the atmosphere has more than doubled since the Industrial Revolution. The pandemic has arguably stirred the levels of methane down, nonetheless, the gas is increasing by 12-part per billion every year, according to the report.
Worryingly, the study finding is in tandem with the predictions of the Intergovernmental Panel on Climate Change (IPCC) that sees the earth warm by 3-4C by 2100.
Environmental, and humanitarian as well
Livestock farming has grown exponentially around the world is contributing to the world’s ailment, while the situation in the factory farm poses a tremendous humanitarian threat as well. It is a twin threat, to say the least, but if at all the world is concerned with humanity.
Just concluding animals are brutally tortured in factory farms would be a gross understatement. They’re tormented in unimaginable ways, something that would send chills down the spines of many.
Not only this, but slaughterhouses and wet markets have also been found to be a hotspot of various diseases, including zoonotic viruses like the novel coronavirus that has infected millions. In France and the US, thousands of slaughterhouse workers were affected by COVID-19 due to the filthy working condition and no scope of maintaining standard hygiene protocols.
