What the World Would Look Like If It Never Stopped Raining

There are places on Earth where it rains practically all the time (Maunawili Ranch on Oahu in Hawaii holds the current record for the longest stretch of measurable rainfall at 331 days), but what would the planet look like if it rained everywhere without relief? That’s what Life Noggin explores in their new video.

First, the plant life that depends on sunlight and limited amounts of water to survive would be in deep trouble. Continuous rain and cloud cover would kill much of the greenery we depend on for breathable oxygen, and most of our crops would also perish.

Finding clean drinking water would also become a challenge. Extreme flooding leads to dangerous pollutants washing into our lakes, rivers, and reservoirs, which would boost the spread of disease. Then there are the natural disasters to worry about: Even if you could find a piece of exposed land on which to make camp, landslides spurred by erosion and even earthquakes caused by loose rocks would be more prevalent.

While a global flood of biblical proportions is unlikely, heavy downpours are still a problem. According to a recent study, chances of Hurricane Harvey-levels of rainfall in Texas have increased sixfold since the late 20th century.

McDonald's May Be Getting Rid of Its Plastic Straws

First Seattle and then the Queen. Could the Golden Arches be next to join the anti-straw movement? As Fortune reports, McDonald's shareholders will vote at their annual meeting on May 24 on a proposal to phase out drinking straws at the company's 37,000-plus locations in the U.S.

If passed, the fast food behemoth would join the ranks of other governments and businesses around the world that have enacted bans against straws in an effort to reduce plastic waste. Straws are notoriously hard to recycle and typically take hundreds of years to decompose.

McDonald's is currently in the process of removing plastic straws from its roughly 1300 outlets in the UK. However, McDonald's board of directors opposes the move in the U.S., arguing that it would divert money from the company's other eco-friendly initiatives, The Orange County Register reports. This echoes comments from the plastic industry, which says efforts should instead be focused on improving recycling technologies.

"Bans are overly simplistic and may give consumers a false sense of accomplishment without addressing the problem of litter," Scott DeFife of the Plastics Industry Association told the Daily News in New York City, where the city council is mulling a similar citywide ban.

If the city votes in favor of a ban, they'd be following in the footsteps of Seattle, Miami Beach, and Malibu, California, to name a few. In February, Queen Elizabeth II was inspired to ban straws at royal palaces after working with David Attenborough on a conservation film. Prime Minister Theresa May followed suit, announcing in April that the UK would ban plastic straws, cotton swabs, and other single-use plastic items.

It's unclear how many straws are used in the U.S. By one widely reported estimate, Americans use 500 million disposable straws per day—or 1.6 straws per person—but it has been noted that these statistics are based on a survey conducted by an elementary school student. However, plastic straws are the fifth most common type of trash left on beaches, according to data reported by Fortune.

Hawaii's Kilauea Volcano Is Causing Another Explosive Problem: Laze

Rivers of molten rock aren't the only thing residents near Hawaii's Kilauea volcano have to worry about. Lava from recent volcanic activity has reached the Pacific Ocean and is generating toxic, glass-laced "laze," according to Honolulu-based KITV. Just what is this dangerous substance?

Molten lava has a temperature of about 2000°F, while the surrounding seawater in Hawaii is closer to 80°F. When this super-hot lava hits the colder ocean, the heat makes the water boil, creating powerful explosions of steam, scalding hot water, and projectile rock fragments known as tephra. These plumes are called lava haze, or laze.

Though it looks like regular steam, laze is much more dangerous. When the water and lava combine, and hot lava vaporizes seawater, a series of reactions causes the formation of toxic gas. Chloride from the sea salt mixes with hydrogen in the steam to create a dense, corrosive mixture of hydrochloric acid. The vapor forms clouds that then turn into acid rain.

That’s not the only danger. The lava cools down rapidly, forming volcanic glass—tiny shards of which explode into the air along with the gases.

Even the slightest encounter with a wisp of laze can be problematic. The hot, acidic mixture can irritate the skin, eyes, and respiratory system. It's particularly hazardous to those with breathing problems, like people with asthma.

In 2000, two people died in Hawaii Volcanoes National Park from inhaling laze coming from an active lava flow.

The problem spreads far beyond where the lava itself is flowing, pushing the problem downwind. Due to the amount of lava flowing into the ocean and the strength of the winds, laze currently being generated by the Kilauea eruptions could spread up to 15 miles away, a USGS geologist told Reuters.
