They’re still killing a few billion other animals yearly, just not whales.

Very large numbers of mammals, birds, reptiles, amphibians and invertebrates are killed on the world’s roads every day. A Humane Society volunteer survey conducted over three Memorial Day weekends in the 1960s estimated that one million vertebrate animals are killed by vehicular traffic daily in the United States. A 2008 Federal Highway Administration report estimates that 1 to 2 million accidents occur each year between large animals and vehicles. Extrapolating globally based on total length of roads, roughly 5.5 million vertebrates are killed per day, or over 2 billion annually.
