To the farmer or grower, an active bee hive ready to mass pollinate is a thing of beauty.
"Every flower needs it, so every piece of fruit needs a bee to get to it," says Reed Soergel, of Soergel's Orchards. "So, to the crop, it's huge."
But bees in Pennsylvania are dying at an alarming rate.
"About 60 percent of colonies dying off here in our state," says Stephen Riccardi, of Penn Environment.
"It's getting into a situation where we're going to start running out of food," said Kevin Hermman, the executive chef at The Porch at Schenley.

Flames from the Erskine Fire engulf a home near Weldon, California, U.S. June 24, 2016.
Kern County Sheriff, Donny Youngblood, told reporters that at least two people were confirmed to have been killed in the inferno, warning that more victims could be found.
Up to 800 firefighters struggled against the so-called Erskine Fire, which broke out on Thursday in the foothills of Kern County. It roared through sun-drenched trees in the mountains of central California and eventually went out of control. On Friday, local authorities told over 3,000 residents in Lake Isabella to be prepared to evacuate, Reuters reported.
"The forces of nature collided with a spark," Kern County Fire Chief, Brian Marshall, told a news conference on Friday. "The mountainous terrain, five years of drought and wind gusts of over 20mph all drove a fire over 11 miles in 13 hours.
A fellow spear fisherman brought the 43-year-old man to Arniston harbour around noon and used the rubber bands from their spear guns as a tourniquet on the wounds, National Sea Rescue Institute Agulhas station commander Reinard Geldenhuys said in a statement.
"It was reported that he was safe in the harbour and suffering bite wounds following a reported shark encounter, believed to be with a Great White shark, while spearfishing off-shore of Ryspunt."
The man had multiple lacerations, a tear to his left leg, and lacerations to his right hand, caused by trying to fight the shark off.
NSRI medics and Fire and Rescue Services paramedics treated the man before he was taken to Bredasdorp hospital, where he was stabilised. He was airlifted to a Cape Town hospital in a serious but stable condition.
Rosy snow is commonly seen at high altitudes when normally green algae turn red from absorbing ultraviolet rays. However, the reddish snow could also be increasing the speed of glacial melt.
The simplest way to understand this is to think about wearing a black shirt on a hot day. People typically try not to do that because darker colored objects absorb a higher amount of incoming light than light-colored objects, which tend to reflect light. Here, it's like a glacier putting on a red shirt, the Washington Post explained.
Let's start this compilation with the Atoyac River, which disappeared overnight drained by a giant 30 meters by 20 meters fissure in the riverbed. The large sink hole cut the water supply to more than 10,000 families for a few days.
One month later, in April 2016, two other rivers flowing through the exact same mountainous region of the eastern state of Veracruz, Mexico also began to dry up due to the formation of sinkholes.

Wednesday night's storm stretched 700 miles across the Midwest and produced more than 1 million lightning strokes and flashes.
Since 1989, every stroke and flash of lightning that happens in the continental U.S. has been recorded in real time by the Vaisala-owned National Lightning Detection Network, based in Tucson, Ariz., which monitors lightning activity 24 hours a day, 365 days a year. This includes the time, location and polarity of cloud-to-ground lightning and cloud pulses, which can stay in a cloud or be connected to cloud-to-ground lightning.
Vaisala estimates the Chicago area had 12-20 flashes of lightning per square mile each year from 2005-14. During the same time period, Illinois had the eighth-highest cloud-to-ground lightning flash density among U.S. states at 14.2 per square mile. Florida had the most -- 21 per square mile.
The fire three hours north of Los Angeles—dubbed the Erskine fire—had spread to an estimated 5,000 acres (20 square kilometers), prompting the mobilization of hundreds of firefighters, the news website Inciweb said.
The authorities closed several highways and evacuated two schools and a retirement home in the agricultural and oil region after the blaze started Thursday afternoon due to unknown causes.
The blaze is "extremely dangerous, extremely volatile," Kern County Fire Captain Tyler Townsend told the Los Angeles Times. "It's one of the most devastating I've ever seen."
The child's mutilated body was found covered in mud in the backyard of the family home in a village near Udaipur, in India.
Local media named the girl as Ravina and said she was sleeping with her father Ranjit Singh and mother on the terrace of their house on Wednesday, when a leopard grabbed the child by her neck around midnight.
The girl's mother did not realise she was missing until around 4am, when they launched a frantic search, the Udaipur Kurin reports.
Teethmarks were found on the girl's body and villagers are reportedly angry that authorities have not done more to stop leopard attacks.
It is the second terrifying incident this month and police and forest authorities have been called in to search for the animal.
Leopards are frequently sighted in the area and pugmarks were found on the ground.

For the first time, scientists have produced a computer image showing huge sections of California rising and sinking around the San Andreas fault.
The vertical movement is the result of seismic strain that will be ultimately released in a large earthquake.
Initially the worst affected counties were Greenbrier and Nicholas, where Governor Tomblin declared the state of emergency on 23 June. A statement from the Governor's office said that the "severe storm event has caused rockslides, mudslides, and flooding and has damaged home, businesses, roads and bridges. Certain portions of Nichols and Greenbrier have been rendered inaccessible because of public infrastructure damage."
Later the state of emergency was expanded to include 44 counties in total. All but the counties in the Northern and Eastern Panhandles in West Virginia have been severely affected and are now under a state of emergency.















Comment: Mysterious indeed. Elsewhere scientists have been baffled by the relentless rise of two Caribbean lakes and off northwest England a new island formed. What is going on?
