PETA to traumatize kids for Thanksgiving
The ads incorporate lenticular technology, so that people 4-feet, 3-inches and shorter will see an image different from the mother carving a cooked turkey in front of two children. Shorter viewers will see the scene with the two children spattered with blood and horrified as the mother cuts into a live bird.
The ad reads: "Traditional Thanksgiving Dinner -- From Your Family Butcher." The smaller type for the adult version reads, "Time to Try Vegan. Get Recipes at PETA.org," but children see, "Say No to Turkey."

to get parents on PETA's side. 
People for Ethical Treatment of People.
And for a large brain, you need lots of energy. By eating meat we were able to have time to explore humanity, do things like pass down language instead of grazing in the fields all day. You would have to eat a two five gallon bucket of grasses to get the same energy as a hunk of lamb.
We should start campaigns on how PETA are trying to make us ignorant grazers again 
The first major evolutionary change in the human diet was the incorporation of meat and marrow from large animals, which occurred by at least 2.6 million years ago.
Who was eating this meat and marrow?
Currently, there is fossil evidence for at least three species of hominins occurring at around 2.6-2.5 Ma: Australopithecus africanus, Australopithecus garhi, and Paranthropus aethiopicus; H. habilis was established by around 2.4-2.3 Ma (Figure 2). There are no butchered bones (or stone tools) found at stratigraphic levels associated with A. africanus or P. aethiopicus, so those taxa are less likely to be our perpetrators. While butchered bones have been found near A. garhi fossils (de Heinzelin et al. 1999), it's only in the Homo lineage, especially in Homo erectus, that we see biological features often linked to meat-eating, such as a decrease in tooth and gut size and an increase in body and brain size (e.g., McHenry 1992; Aiello and Wheeler 1995; Antón 2003; Braun et al. 2010).

This is one of the most complete skulls of this species.
Why did hominins start eating more meat and marrow?
"Why" questions are notoriously difficult to answer about the past, but we can examine some of the benefits that meat and marrow provide. Meat and marrow are calorie-dense resources with essential amino acids and micronutrients (Milton 1999), and aquatic fauna offer resources rich in nutrients needed for brain growth (e.g., Broadhurst et al. 2002). Increasing the consumption of animal foods could have allowed hominins to increase their body size without losing mobility, agility, or sociality (Milton 1999). But what was the frequency and quantity of nutrients obtained by hominins from animal tissues versus other foods? Hominins at sites FLK 22 and FLKN 1-2, Olduvai Gorge, broke long bones of small to medium-large mammals in direct proportion to their estimated gross caloric yield from marrow fat (Blumenschine & Madrigal 1993 - but see Bunn et al. 2010 for a different interpretation of hominin behavior at FLKN 1-2). Long bone abundance of medium-large mammals at FLK 22 is also correlated significantly and positively to the net yield of marrow bones (Blumenschine & Madrigal 2000). Optimal foraging theory dictates that foods in the optimal diet set are expected to be consumed whenever encountered; the carcass encounter rate is dependent on a variety of ecological variables (Blumenschine & Pobiner 2006). This indicates that by at least 1.8 million years ago, carcass-processing decisions may have taken into account the energy yield of a variety of foods. Assuming opportunistic encounters with carcasses, these net yields are comparable to, or higher than, those for most, if not all, non-mammal food items harvested by tropical hunter gatherers (Blumenschine & Pobiner 2006 and references therein).
