This is what your local supermarket would look like without bees! According to Greenpeace Bees pollinate over 80 percent of the crops that we eat. Over the last 5 years over 33 percent of the bee population has died off.
This is an incredibly high number. It is theorized that this is due to pesticides and disease.
The Puerto Rican bee is a gAHB this means a domesticated African honey bee. These bees are so important because they are much more resistant to diseases. This bee could be the holy grail of bees, if managed correctly repopulating the entire world with a hardier bee.
