To complete the 680-mile drive under current conditions, you would have to allow 21 hours for travel. Why? Traveling north-to-south across the country requires eight ferry trips across fjords. Norway's fjords are too deep and too wide to support bridges. Well, above water ones that is.
A $25-billion project by the Norwegian Public Roads Administration poses a possible solution to that problem: floating underwater tunnels.
The tunnels could cut trip time to 10.5 hours by reducing the need for ferry rides. The project is expected to be completed by 2023. Each tunnel would be suspended under 100 feet of water, held up by pontoons on the fjord's surface and possibly an anchor bolted to the bedrock. Each fjord would be equipped with two tunnels: each two-lane, one for traffic flowing in each direction.

Underwater tunnels aren't a new idea for Norway. The country has 1,150 traffic tunnels, 35 of which are located under shallow bodies of water. Fjords, however, can be a mile deep, creating a challenge for conventional tunnels.
The floating underwater tunnels will allow boats to still traverse the fjord without the worry about hitting or being blocked by a bridge.
But there's still a long way to go before floating underwater tunnels become reality. Engineers have several questions to answer, including how wind, waves and currents will affect the structures. If the tunnels prove too difficult, Inhabitat reported, politicians have the right to send the funding to another project.
The following Norwegian Public Roads Administration video offers more information about the project:
At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.

<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>Avocado and almond crops depend on bees for proper pollination.

<p>Salazar and other Columbian beekeepers described "scooping up piles of dead bees" year after year since the avocado and citrus booms began, according to Phys.org. Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>EcoWatch Daily Newsletter
Australia is one of the most biodiverse countries in the world. It is home to more than 7% of all the world's plant and animal species, many of which are endemic. One such species, the Pharohylaeus lactiferus bee, was recently rediscovered after spending nearly 100 years out of sight from humans.
