Hi, this is Emily. You may have noticed that conservation can be a topic of debate. Regardless of your views on bees, trees, or other species, there is a compelling economic argument for preserving as many species as possible: biodiversity is advantageous for the economy.
In a recent study co-authored by MinuteEarth’s writer and ecologist Peter Reich, scientists investigated forests worldwide. They discovered that forests with a greater variety of tree species grow faster and larger than those with fewer species. This is logical because trees of a single species often compete for the same resources. In contrast, trees of different species have diverse strategies, enabling them to collectively utilize a larger portion of the available resources.
The implications are substantial: the world’s logged forests produce at least 35% more timber than they would if each stand of trees consisted of only one species. This results in at least $200 billion in additional revenue annually. This “diversity dividend” is at least 20 times greater than the total amount currently spent on conservation efforts.
Economists are also identifying tangible diversity dividends in other sectors. For example, on farms, different pollinators operate at various times. Maintaining a diverse array of insects ensures that crops will produce fruit and revenue whenever they flower. In our lakes and rivers, a wider variety of toxin-eating microbes can clean up more pollutants, thereby reducing the multi-billion dollar cost of maintaining clean waterways.
Assigning a dollar value to biodiversity in every ecosystem is challenging, and financial metrics are not the only way to assess the value of nature. However, in many instances, healthier, more diverse ecosystems appear to align with a healthier economic outcome.
So, despite what you may have heard, money really does grow on trees and bees!

Engage in a structured debate with your peers on the topic: “Is biodiversity essential for economic growth?” Prepare arguments and counterarguments based on the article’s content and additional research. This will help you understand different perspectives and the economic implications of biodiversity.
Analyze a case study on a forest ecosystem with diverse tree species. Examine how biodiversity contributes to economic benefits such as increased timber production. Present your findings in a group presentation, highlighting the “diversity dividend” concept discussed in the article.
Participate in a field trip to a local forest or farm to observe biodiversity in action. Document different species and their interactions. Reflect on how these interactions might contribute to economic benefits, drawing parallels to the examples provided in the article.
Conduct a research project on the role of diverse pollinators in agriculture. Investigate how different species contribute to crop yield and economic outcomes. Present your research findings in a written report, emphasizing the economic advantages of maintaining pollinator diversity.
Attend a workshop that focuses on valuing ecosystem services. Learn about different methods to assign economic value to biodiversity. Apply these methods to a specific ecosystem, and discuss how these valuations can influence conservation policies and economic decisions.

Hi, this is Emily. You may have noticed that conservation can be contentious. But no matter how you feel about bees, trees, or even other species, here’s a practical argument for keeping as many species around as possible: biodiversity is beneficial for the economy.
For example, in a recent study co-authored by MinuteEarth’s own writer and ecologist Peter Reich, scientists examined numerous forests around the world and found that stands with more tree species grow faster and larger than those with fewer species. This makes sense: trees of a single species often compete for the same resources, while trees of different species have varied approaches, allowing them to utilize a larger portion of the available resources together.
The benefits are significant: the world’s logged forests produce at least 35% more timber than they would if each stand of trees had only one species, resulting in at least $200 billion in additional revenue each year. This diversity dividend is at least 20 times more than the total amount currently spent on conservation.
Economists are also discovering real diversity dividends in other areas. For instance, on farms, different pollinators work at different times, so maintaining a diverse set of insects helps ensure that crops will yield fruit and revenue whenever they flower. In our lakes and rivers, a greater variety of toxin-eating microbes can clean up more pollutants, reducing the multi-billion dollar cost of maintaining clean waterways.
Of course, it’s challenging to assign a dollar value to biodiversity in every ecosystem, and money isn’t the only way we want to measure the value of nature. However, in many cases, healthier, more diverse ecosystems seem to correlate with a healthier bottom line.
So despite what you may have heard, money really does grow on trees and bees!

This version removes informal language and maintains a professional tone while preserving the original message.
Biodiversity – The variety of plant and animal life in a particular habitat or in the world as a whole, often considered to be important for environmental health and stability. – The Amazon rainforest is a hotspot of biodiversity, hosting thousands of species that are not found anywhere else on Earth.
Economy – The system of production, distribution, and consumption of goods and services within a particular geographic region. – The transition to a green economy can create new jobs while reducing environmental impacts.
Forests – Large areas covered chiefly with trees and undergrowth, playing a crucial role in carbon sequestration and habitat provision. – Sustainable management of forests is essential to combat climate change and preserve biodiversity.
Species – A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. – Conservation efforts are critical to prevent the extinction of endangered species due to habitat loss and climate change.
Resources – Natural materials or substances that can be used for economic gain, such as minerals, water, and fertile land. – Efficient utilization of resources is vital for sustainable development and minimizing environmental degradation.
Revenue – Income generated from normal business operations and includes discounts and deductions for returned merchandise. – Governments often rely on revenue from carbon taxes to fund renewable energy projects and environmental initiatives.
Conservation – The protection and preservation of natural environments and wildlife to prevent exploitation, destruction, or neglect. – Conservation strategies are essential to maintain ecosystem services that support human life and economic activities.
Ecosystems – Communities of living organisms in conjunction with the nonliving components of their environment, interacting as a system. – Healthy ecosystems provide vital services such as clean water, air, and fertile soil for agriculture.
Pollutants – Substances that contaminate the environment, causing harm or discomfort to ecosystems or living organisms. – Reducing industrial emissions is crucial to decrease air pollutants that contribute to climate change and health problems.
Agriculture – The science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products. – Sustainable agriculture practices can improve food security while minimizing environmental impacts.
