Three American Cities That Could Be The Next Cape Town
The world is watching as Cape Town residents count the days (and drops) to Day Zero—when the city's tap run dry. The South African city is in the midst of its worst drought in history, and unless a substantial amount of rain falls in the coming months, it could become the first major city to run dry. Poorer citizens are already bearing the brunt of the water crisis, and all residents have been advised to limit their water consumption to only 50 liters, or 13.2 gallons a day. Think two-minute showers and reusing your bathing water to flush the toilet.
It sounds like a Mad Max movie, but the Cape Town water shortage is quite real and could be closer to reality for the rest of us than we would like. The World Wildlife Fund estimates that by 2025, two-thirds of the world population could be struggling with water shortage. And right here in the U.S., cities across the country are watching their water reserves dwindle.
Although factors such as poor planning and population growth are driving droughts in some regions, there is one common culprit that is exacerbating water crises around the globe: climate change. Experts point to high temperatures, drying rivers and melting snowpack as some of the factors behind the dry spells. They're also a wake-up call that the climate crisis is no distant threat. In fact, it's already affecting three big American cities and the daily lives of millions.
Here are three big American cities that could be the next Cape Town:
1. Los Angeles
California has a long history of water shortage, and Los Angeles is often at the center of the dust storm. In the early twentieth century, the dispute for water between the city and rural farmers was so bitter that it became known as the California Water Wars (and was turned into the Academy Award-winning movie Chinatown (1974) starring none other than Jack Nicholson).
Decades have passed since, but the city's water woes are seemingly getting worse. In 2014, the City of Angels was listed as one of the most water-stressed large city in the world by The Nature Conservancy. One of the proofs was that LA was hit with the worst drought in at least 1,200 years in 2014, triggered by high temperatures and reduced rainfall linked to the change of climate and weather patterns.
As a result, for the first time in history, Angelenos were instructed to limit their water usage by 25 percent in 2015. The directive has since been lifted, but if the world doesn't tackle the climate crisis, new dry spells will always be on the horizon. This year, for instance, snowpacks in the northern part of the state are frighteningly low—and they're one of the main suppliers of water for California.
2. Salt Lake City

For every degree Fahrenheit of warming in the Salt Lake City region, the flow of nearby streams could decrease by an average of 3.8 percent annually, according to a recent report by the Western Water Assessment. The number is worrisome, considering that global temperatures have been steadily rising, and the city depends on healthy streams for its fresh water supply.
Making matters even worse, rivers that flow into the Great Salt Lake—and that could be an alternative source of water to the city—are headed in the same direction. The lake itself has shrunk to nearly half of its former size in the last 170 years. It's no wonder that in 2014, the University of Florida's Environmental Hydrology Laboratory found that Salt Lake City was at a high level of fresh water vulnerability.
Residents have already started feeling the effects of water scarcity. In 2015, the mayor's office asked for cautious with water waste. Instructions included adjusting sprinklers and checking for leaks to protect the city's fragile water supply. If you ask us, it's time for the city to take climate action, especially since its population is expected to nearly double by 2050.
Why is Miami on this list? After all, the city is surrounded by water in all forms—it literally sits on the sea and has access to plenty of rain, lakes and groundwater. However, the megacity is facing climate-related water concerns no less daunting than any other city on this list.
We all know that climate change has been fueling rising sea levels, and it's not just in the Pacific Islands. In America's Magic City, the rising seawater is leaking into, and contaminating, fresh water supplies above and underground. And although the problem has been around since the 1930s, rising sea levels mean these leaks are increasing at unprecedented rates . The water is even breaching underground defense barriers that were installed in recent decades and reaching freshwater wells.
As a result, neighboring cities are already struggling to find drinkable water. Hallandale Beach, which is just a few miles north of Miami, had to close six of its eight wells due to saltwater intrusion. And residents of the nearby Everglades National Park (including alligators) are getting salty with the ocean sweeping into the swamps. Miami-Dade residents all well aware of the risks, as more than 50 percent believe that the climate crisis will impact them personally.
As mean temperatures creep up, there's a risk that the crisis will worsen water stress across the U.S. and the rest of the world. But it's not a lost cause. We can work together with government officials, businesses, schools and faith communities to take climate action to the next level. Together we can reduce carbon emissions by adopt viable climate solutions—such as ditching dirty fossil fuels and embracing renewable energy.

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.
Migratory beekeeping involves trucking millions of bees across the U.S. to pollinate different crops, including avocados and almonds. Timothy Paule II / Pexels / CC0<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. FRANK MERIÑO / Pexels / CC0<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>
