Did you know that a single honey bee weighs only about a tenth of a gram? Despite their tiny size, bees are incredibly valuable to our world. The crops they pollinate are worth a staggering $215 billion globally. Bees help produce 75% of the fruits, vegetables, and nuts we eat, and their pollination services are estimated to be worth at least $24 billion to U.S. farmers. They even play a key role in pollinating coffee plants!
When we talk about the decline in bee populations, we often focus on the European honey bee. This species is like a domesticated animal, similar to cows or chickens, and is managed for honey production and crop pollination. Normally, a small percentage of bee colonies die off each winter. However, between 1947 and 2005, U.S. beekeepers reported losing nearly half of their bees. By 2006, some reported losses as high as 90%, a phenomenon known as Colony Collapse Disorder (CCD).
CCD is when a hive loses its adult worker bees, leaving behind honey, young bees, and the queen. Wild bee species are also in trouble, with estimates suggesting that up to half of all wild bee species may have gone extinct over the past 120 years. Bee population declines have been noted since 1868, but the current rate is unprecedented, and the exact causes are still not fully understood.
Several factors are likely contributing to the decline in bee populations. Pesticides, especially a type called neonicotinoids, can harm bees by affecting their ability to communicate and find food. Habitat loss has also reduced the availability of diverse food sources, leading to nutritional problems for bees.
When bee colonies are weakened by pesticides or lack of food, they become more vulnerable to viruses, parasites, and other infections. Some bees have natural resistance to certain infections, and scientists are exploring ways to breed bees with enhanced resistance to help colonies survive.
Research suggests that bee declines are caused by a combination of factors, including pesticides, habitat loss, and infections. However, there are ways we can help. Planting more flowers, reducing pesticide use, managing invasive species, and supporting wild bee populations are all actions that can make a difference.
It’s crucial to maintain a healthy relationship with nature, whether in our gardens or at the grocery store. Bees are vital to our ecosystem and food supply, and their importance cannot be overstated.
Stay curious and keep learning about the amazing world of bees!
Research the different types of bees and their roles in pollination. Create a presentation or poster to share with the class, highlighting the importance of bees in agriculture and ecosystems. Include interesting facts, such as the economic value of bee pollination.
Design and build a small bee habitat or “bee hotel” using natural materials. Place it in a garden or a green space near your school. Observe and document any bee activity over time, and discuss how providing habitats can help support bee populations.
Participate in a role-playing debate about the use of pesticides and their impact on bee populations. Take on roles such as farmers, environmentalists, scientists, and policymakers. Discuss the pros and cons of pesticide use and explore alternative solutions.
Create an interactive quiz for your classmates about bees, their importance, and the challenges they face. Use online tools to make the quiz engaging and educational. Include questions about Colony Collapse Disorder and ways to help bees.
Work with your classmates to plan and plant a pollinator-friendly garden at your school. Choose a variety of flowers that bloom at different times of the year to provide a continuous food source for bees. Monitor the garden’s impact on local bee activity.

A single honey bee weighs just a tenth of a gram, but a beehive is worth more than its weight in gold. Crops pollinated by bees are valued at $215 billion worldwide, and they contribute to 75% of the fruits, vegetables, and nuts we consume. Their pollination services are estimated to be worth at least $24 billion to U.S. farmers, though this may be an underestimate. Bees also play a crucial role in pollinating the coffee plant.
When discussing bee population declines, the focus is often on the European honey bee. This species is essentially a domesticated animal, similar to cows, sheep, or chickens, and is managed for honey production and crop pollination. Each winter, it is normal for a small percentage of colonies to die off, but between 1947 and 2005, U.S. beekeepers reported losing nearly half of their bees. By 2006, losses as high as 90% were reported, leading to the term Colony Collapse Disorder (CCD).
A hive affected by CCD is characterized by the absence of adult worker bees, with honey and immature young left behind, leaving only the queen bee. Additionally, wild bee species are facing significant challenges, with estimates suggesting that over the past 120 years, as many as half of all wild bee species may have gone extinct. Bee population declines have been documented as far back as 1868, but the current scale of decline is unprecedented, and the causes are not fully understood.
Pesticides, particularly a class known as neonicotinoids, are among the likely contributors to bee declines. Exposure to neonicotinoids can be harmful to bees, affecting their ability to communicate and forage. Habitat loss has also reduced the availability of diverse food sources for bees, leading to nutritional deficiencies.
Bees can become ill when their colonies are weakened by pesticides or food scarcity, making them more susceptible to viruses, parasites, and other infections. Some bees exhibit natural resistance to certain infections, prompting scientists to explore breeding strategies to enhance this resistance in colonies.
Research indicates that bee declines are likely driven by a combination of factors, including pesticides, habitat loss, and infections. However, there are potential solutions, and individuals can contribute by planting more flowers, reducing pesticide use, managing invasive species, and supporting wild bee populations.
It is essential to maintain a healthy relationship with nature, whether in gardens or grocery stores. The importance of bees to our ecosystem and food supply cannot be overstated.

Bees – Insects that are known for their role in pollination and producing honey. – Bees are crucial for the pollination of many crops, which helps in food production.
Pollination – The process by which pollen is transferred from the male part of a plant to the female part, allowing plants to reproduce. – Without pollination, many plants would not be able to produce fruits and seeds.
Habitat – The natural environment where a plant or animal lives and grows. – The rainforest provides a rich habitat for a diverse range of species.
Decline – A decrease in the number or quality of something, often referring to populations of organisms. – The decline in bee populations is a concern for environmental scientists.
Pesticides – Chemicals used to kill pests, but they can also harm beneficial insects like bees. – The use of pesticides in agriculture can negatively impact the surrounding ecosystem.
Species – A group of similar organisms capable of interbreeding and producing fertile offspring. – The giant panda is an endangered species that requires conservation efforts.
Ecosystem – A community of living organisms interacting with their physical environment. – A healthy ecosystem includes a variety of plants, animals, and microorganisms.
Food – Substances consumed by organisms to obtain energy and nutrients necessary for growth and survival. – Plants are a primary source of food for many herbivores in an ecosystem.
Infections – Invasions and multiplications of microorganisms such as bacteria, viruses, and parasites that are not normally present within the body. – Infections can spread rapidly in dense animal populations, affecting their health and survival.
Biodiversity – The variety of life in a particular habitat or ecosystem. – High biodiversity in an ecosystem can contribute to its resilience against environmental changes.
