In today's broadcast we talk about one of the key agents that help in the pollination of flowers and plants. Bees are an essential part of our ecosystem and the decline in their population is now a concern for its devastating effects on the planet's biodiversity. Beehive reduced numbers is also affecting honey producers in Spain, who have to face production costs in a very competitive market. We'll talk about it with Diego Juste, spokesman of the association of farmers and cattle breeders in Spain, who states the importance of reading the labels, as in most cases, consumers are not buying just honey. We'll also talk to doctor and researcher Raquel Martín about a vaccine that is being developed in the research centre of Marchamalo, in the region of Guadalajara, to protect hives from one of the deadliest illnesses that affect bees.
