Just so you won't feel like an "embarrassment" for being vegan but eating food that tastes like meat.
From The Guardian US edition:
Most of the meat people eat in 2040 will not come from slaughtered animals, according to a report that predicts 60% will be either grown in vats or replaced by plant-based products that look and taste like meat.
The report by the global consultancy AT Kearney, based on expert interviews, highlights the heavy environmental impacts of conventional meat production and the concerns people have about the welfare of animals under industrial farming.
“The large-scale livestock industry is viewed by many as an unnecessary evil,” the report says. “With the advantages of novel vegan meat replacements and cultured meat over conventionally produced meat, it is only a matter of time before they capture a substantial market share.”
