One-third of the world’s food supply relies on pollinators

Bees are crucial for pollination and food security

When animals and insects pick up the pollen of flowers and spread it, they allow plants, including many food crops, to reproduce. The most common pollinator is the bee, but bees are at risk from pollution and pesticides.

Human beekeeping has been traced back to 7000 BCE

Eighty-seven of the world's leading crops rely on pollination in some way, including 43 that are highly dependent or entirely reliant on it. Without pollinators, key foods such as apples, avocados, and almonds would likely become extinct, pushing entire ecosystems into collapse.

Agricultural intensification has accelerated declines in pollinator populations

The practice of using farmland more frequently to increase its yield increases the number of residual pesticides and decreases botanical biodiversity. These processes tend to decrease carrying capacity for pollinators by eliminating food sources and nesting habitats.

South Asia and sub-Saharan Africa are most at risk from falling pollinator numbers

Researchers at the Harvard T.H. Chan School of Public Health found that declines in pollinator populations would lead to higher rates of nutritional deficiencies, particularly in developing nations. Nations with large populations, such as China and India, would also be significantly impacted.

Butterfly populations have declined by 22% from 2000 to 2020

Research suggests that one in every five butterflies is lost due to pesticide use, habitat loss, and climate change. Playing a vital role in pollination, their declining populations threaten plant reproduction and the health of ecosystems.

How the world produces food, in drone photos

Drone photographer George Steinmetz spent a decade documenting the vast scope of humanity's agriculture using drone photography. Roughly 40% of the Earth's surface is dedicated to growing food, and experts suggest we must produce 60% more food than we do now to feed the projected population in 2050. Browse the absolutely stunning photos here.

Some mosquitoes are key pollinators—and eat disease-carrying mosquitoes

​​There are more than 3,500 species of mosquitoes, and only a small fraction of them bite humans. They also play vital roles in the ecosystem: One young elephant mosquito, for example, can eat dozens of smaller mosquitoes that bite humans in just one day. Sometimes mosquito-gobbling species are released by humans to control other mosquitoes.

Visual deep dive into the collapse of insects

Microplastics have been shown to disrupt photosynthesis in plants and algae

A major study found that pieces of plastic less than five millimeters long are causing an estimated 4% to 14% loss of the world's wheat, rice, and maize, potentially putting an additional 400 million people at risk of starvation within 20 years. The damage from microplastics to crops may already rival the impact of climate change on food supplies.

Discover the economic value of coral reefs, which benefit one billion people worldwide

The National Oceanographic and Atmospheric Administration estimates that US commercial and recreational fisheries valued at $200M depend on coral reefs, which provide up to $1.8B in flood protection by absorbing 97% of wave energy. Combined with the benefits from tourism, US coral reefs provide $3.4B in value annually.

Invasive species are the third biggest threat to Earth's biodiversity

According to the World Wildlife Fund's Living Planet Report 2020, changes in land and sea use account for about half of all recorded threats to the diversity of the planet's species. Species overexploitation is the second-largest proportional threat at 24%, while invasive species make up 13%.

In 2024, Americans bought over $7B of cut flowers

That's more than any other country in the world. Most of the flowers Americans purchase are imported, creating an economy that's both booming and reliant on dwindling natural resources.

The Russia-Ukraine war greatly affected the global food supply

Russia's invasion devastated Ukraine's agricultural sector, destroying farms, ports, and grain infrastructure and causing over $40B in losses. Disrupted exports fueled global food insecurity, while Moscow leveraged its grain exports to expand influence across the Global South.

Superbugs could claim 1.9 million lives per year by 2050

The increased use of antibiotics combined with an aging population, is projected to result in an almost 50% increase in global deaths from antimicrobial resistance each year. At the same time, antibiotic use for livestock is expected to increase by 30% over the same time frame.

The average American eats over 25 pounds of bananas every year, but we won't for long if a deadly soil fungus continues to spread. Learn what scientists are doing to save the popular fruit.

Mycotoxins are toxic compounds produced by fungi—some show up in food

About a quarter of the world’s agricultural products are contaminated with mycotoxins. Some of these compounds can cause serious health problems, including cancer, so the US government has set up monitoring programs to detect them in our food and in animal feed. Humans can become ill if they eat contaminated food, but also if they ingest products from animals that had previously consumed these toxic compounds, such as milk from a cow that ate contaminated corn.

Various pollutants may be contributing to a male infertility crisis

Male infertility, due to declining sperm counts or quality, accounts for about half of the cases of infertility among couples. Recent research has found that global sperm counts fell, on average, by 1.2% per year between 1973 and 2018—from 104 million to 49 million per milliliter. From 2000, this rate of decline accelerated to more than 2.6% per year. (Some users may encounter a paywall.)

The economics of horseshoe crab blood

Horseshoe crabs are older than dinosaurs and have survived five mass extinctions that wiped most life from the planet. But it's only now that their future as a species is in danger. This blood, worth about $60,000 per gallon, is hyper-sensitized to certain bacteria that are fatal to humans. This 17-minute podcast dives into humanity's pursuit of horseshoe crab blood, a "somewhat magical" mixture heavily relied on by the pharmaceutical industry.
