The total animal number is dominated by shellfish.
Animals who died per American meat-eater (2000=100%)
Land animal deaths are dominated by chickens raised for meat,
which have shown a sharp 16% decline since 2004.
Cattle and pig deaths have shown a steady decline for more than a decade.
Chickens for eggs show no clear trend, though the last two
years saw a marked drop.
Turkey and duck deaths have both shown dramatic decreases
over the last decade, though the large variability makes it
difficult to know with confidence whether this marks a trend.
