"We have to consider that the foods we ingest let a certain amount of soluble toxic substances dispersed in the environment into our bodies. These polluting substances are harmful if we breathe them in, but they are even more so if we ingest them. By consuming meat, we put ourselves precisely in that position, because such substances in the atmosphere fall back to Earth, and hence, onto the grass that, when eaten by cattle, introduces harmful substances into their adipose deposits and therefore into their flesh, and finally, onto our plates."
