Thinking of switching to bio

I’m thinking of switching my major to biology. Everyone I have mentioned this to tells me this would be a horrible idea. I’m not sure why they say this and any time I ask they avoid the question or give roundabout answers. They all tell me I should go into chemistry instead. I’m guessing there are more job opportunities in chemistry or possible less further education I would need to get. Can someone help me out here? What do I need to know going into it and who would you recommend go into biology?
