Did you ever see that guy walking around Central Park who's an expert on plants and berries and knows which are edible and which are poisonous? It always seemed to me that you would need a degree in botany to really know what's safe and what's not. So I've played it safe by never eating anything in the park unless it was from a hot dog stand (which is scary sometimes as well). But did you know that some substances might be alright for you and I to ingest and dangerous for another species?
