That's all well and good, but your curriculum has left no room for the chemistry that will also be needed to understand the biology. Not to mention a complete course covering the range of biological topics.
The fact is, most undergraduate level biology types will not be using math or statistics very much, but they will need to understand basic chemistry, and they certainly should have an understanding of ecology, evolution, genetics, and microbiology at a basic level (whatever their specialization). So which do we choose? Something that would be undeniably helpful in dealing with the world, but that wouldn't be all that useful in a biology career, or something that is critical to a well-rounded understanding of the field.
It's like saying a CS major should have a good understanding of economics because it's a major application of their field, and then cutting a year out of the math curriculum to fit it in.
