If by modern you mean industrial type meat factories, no.
The conditions have been documented in numerous documentaries though.
Meat should be taxed
Dairy should be taxed
Seafood should taxed
You should not tax such a basic need
Stop with these questions already
Guardian: Huge reduction in meat-eating ‘essential’ to avoid climate breakdownHuge reductions in meat-eating are essential to avoid dangerous climate change, according to the most comprehensive analysis yet of the food system’s impact on the environment. In western countries, beef consumption needs to fall by 90% and be replaced by five times more beans and pulses.
The research also finds that enormous changes to farming are needed to avoid destroying the planet’s ability to feed the 10 billion people expected to be on the planet in a few decades.
Food production already causes great damage to the environment, via greenhouse gases from livestock, deforestation and water shortages from farming, and vast ocean dead zones from agricultural pollution. But without action, its impact will get far worse as the world population rises by 2.3 billion people by 2050 and global income triples, enabling more people to eat meat-rich western diets.
This trajectory would smash critical environmental limits beyond which humanity will struggle to live, the new research indicates. “It is pretty shocking,” said Marco Springmann at the University of Oxford, who led the research team. “We are really risking the sustainability of the whole system. If we are interested in people being able to farm and eat, then we better not do that.”
Let's have fewer people! Then there will less consumption of everything. Problem solved.
