Olive oil is a liquid fat obtained by mashing whole olives and extracting the oil. A superfood staple of the Mediterranean diet, olive oil is used in kitchens around the world for frying, sauteing, baking, and as a condiment. It can also be widely found in cosmetics, soaps, and pharmaceutical products.

Globally, 2.6 million tons of olive oil were consumed last year. Spain is currently the world’s largest producer of this “liquid gold,” accounting for 44% of global production. The second largest producer of olive oil is Italy, followed by Greece, Tunisia, Turkey, and Morocco.

But recently, the price of olive oil has been rocketing up. Droughts, wildfires, floods, and heat waves, combined with pests, have punished olive-producing regions around the world. The climate-fueled extreme weather has significantly impacted olive oil production in southern Europe. Olive trees are exceedingly vulnerable to climate change.

Spain, for example, typically produces somewhere between 1.3 to 1.5 million metric tons of olive oil each harvest. However, officials expect a production range of only 830,000 to 850,000 metric tons this season.

This shortage has sent prices soaring. According to the International Monetary Fund, the average price of olive oil has doubled over the past two years. In fact, the price is currently hovering at or around $10,000 per metric ton. And there doesn’t seem to be much relief in sight.

The record-breaking price has also unsurprisingly fueled a surge in crime, with criminals targeting supermarkets, oil mills, and olive groves.

The changing climate continues to threaten food security around the world.

Honey bee colonies in the United States have experienced annual population declines since 2006. Commercial beekeepers have reported honey bee colony loss rates averaging 30% each winter, which is startling when compared to historical loss rates of just 10-15%. According to the USDA, there are many factors contributing to this decline, including parasites, pests, diseases, pesticides, and a phenomenon called Colony Collapse Disorder, in which worker bees abandon a hive and leave behind the queen.

According to a new study by researchers from Cornell University, beeswax in managed honey bee hives contains a variety of pesticide, herbicide, and fungicide residues. Because bees reuse wax over years, these harmful chemicals can accumulate inside hives, exposing current and future generations of bees to long-term toxicity.

The study, which was recently published in the Journal of Veterinary Diagnostic Investigation, adds that humans may also be exposed to these pesticides through contaminated honey, pollen, and beeswax (which is used in certain soaps, lotions, and cosmetics). However, the amounts in these products are unlikely to pose a major threat to human health.

Pesticides get into the beeswax when bees feast on the nectar and pollen of plants that have been treated with the chemicals. According to the researchers, understanding which contaminants are impacting domestic honey bee populations could help better protect them and other pollinators, including birds, bats, wild bees, and other insects.
