“And so obvious”
A netizen shared his thoughts on the sources of pollution on his Facebook account.
“A large number of people still seem to think that cows have something to do with geoengineering… Even though it is already so obvious that the main source of pollution is 99% there are airplanes that spray chemical aerosols over people’s heads for a lot of money,” he explained.
Airplane or cow?
According to „Bloomberg“the “humble burger” contributes more to global warming than a jet plane. Animal husbandry responsible for 14.5 percent of man-made greenhouse gases, with cattle accounting for the largest share.

Meanwhile, global aviation sukuria only 2 percent of total greenhouse gas emissions.
Methane is produced by animals considered one of the biggest issues when it comes to climate change. Although methane decays faster than carbon dioxide in the atmosphere, it contributes more to the greenhouse effect. According to the United Nations (UN), reducing methane is one of the best ways to slow global climate change.
About 70 percent pollutants emitted by cattle sukuria low- and middle-income countries where inefficient production meets increasing consumer demand. Meanwhile, for example, American cattle grow bigger and faster, which means they produce more meat and less greenhouse gas emissions.
Who pollutes the most?
The five main greenhouse gases are carbon dioxide, nitrous oxide, methane, chlorofluorocarbons and water vapor, according to NASA.

in 2023 Climate Trade compiles the most polluting industries in the list the fossil fuel sector took first place. After a brief decrease during the COVID-19 pandemic in 2022 they increased by 1 percent. and reached 40.5 gigatons of CO2.
In second place is the agricultural sector. It is responsible for approximately 11% of greenhouse gases. According to the UN Food and Agriculture Organization, in 2018 9.3 billion was thrown away due to agricultural activities worldwide. tons of CO2 equivalent, mainly methane and nitrous oxide emissions from crop and animal husbandry activities.
Fashion is cited as the third most polluting industry, generating around 10% of all emissions. annual carbon footprint, more than all international flights and sea shipping combined.
Greenhouse gas emissions are not the only problem facing the fashion sector – enough water is used annually to quench the thirst of five million people. In addition, this industry generates millions of tons of plastic and other waste that pollute the air and oceans.
The retail trade of food products is also mentioned, the majority of emissions of which are food and plastic waste. It is estimated that food waste alone accounts for 8-10 percent. of global greenhouse gas emissions.
Transport, which emits about a fifth of greenhouse gases, came in fifth. About 40 percent of these pollutants is the transport of goods, the rest is passenger transport, mostly air.
A discussion with many nuances
As Frank Mitloehner, a professor in the University of California’s Department of Animal Science and an air quality specialist, points out, there are many nuances to the emissions debate. Although people often look to simple analogies to make it easier to understand the human impact on climate, they sometimes lead to more confusion than clarity.
“First, when we say that a hamburger puts more greenhouse gases into the atmosphere than a single plane trip, we only reinforce the misconception about the true amount of emissions from aviation,” the professor wrote.

In the world, animal husbandry accounts for 14.5 percent. emissions of greenhouse gases. This figure is often cited in claims that eating meat is a greater enemy of the planet than burning fossil fuels used in aviation, the scientist notes. However, looking a little more narrowly, other trends can be seen.
For example, livestock production in the United States accounts for a much smaller share of total emissions than the rest of the world – 3.9 percent. This low number is partly due to the fact that the United States is industrialized and wealthy. In addition, it is one of the largest consumers of energy, fossil fuels and transport, which gives livestock a smaller share statistically. In addition, US livestock emit significantly less gas than other countries such as Brazil, China, India, and European Union countries.
But Americans fly far more than people in any other country. So if the global livestock figure seems inflated relative to the US population, the global aviation figure underplays the importance of US emissions.
What are chemtrails?
The very word “chemtrails” is associated with conspiracy theories. This is what Internet users call the condensate trails that follow airplanes.
These are the tracks left by airplanes is formedwhen water vapor and fine soot particles formed by burning jet fuel freeze into ice crystals. At low humidity, they persist and eventually create visible vapor trails in the sky.
Differences in humidity explain why some aircraft leave vapor trails and others do not.
Conspiracy theory about “chemtrails” became popular back in the 1980s. They were originally said to be used to reduce or stun the population.
15min wrote about it before.
15min the verdict. Partly a lie. Animal husbandry is responsible for 14.5 percent. of man-made greenhouse gases, with cattle accounting for the largest share. Meanwhile, global aviation accounts for only 2 percent. total emissions. However, such a comparison has many nuances, for example, taking the United States as an example. But chemtrails themselves are just a conspiracy theory.
