What is biodiversity and why is it fundamental to life on Earth?
Biodiversity refers to the variety of all forms of life on our planet, covering the different organisms present in both terrestrial, marine and aquatic ecosystems. It involves genetic diversity within species, species diversity in flora and fauna and the diversity of ecosystems, such as forests, deserts, coral reefs and rivers, for example.
Why is biodiversity essential for the balance of ecosystems? Biodiversity is essential for maintaining ecosystem services, such as water purification, oxygen production and climate regulation. Furthermore, genetic diversity confers resilience against diseases and environmental changes, allowing species to adapt and survive. Each species plays a unique role in its ecosystem, contributing to the productivity and stability of that system.
How does biological diversity impact the quality of human life? The quality of human life is profoundly affected by biodiversity. It is a vital component for the existence of healthy ecosystems, which, in turn, are crucial for human survival. They provide food, medicine and raw materials, regulate the climate, control disease and provide spaces for recreation and spiritual well-being. The stability of diverse ecosystems also protects against natural disasters and helps adapt to climate change.
Ecosystem diversity encompasses a variety of habitats, which improves resilience to disasters and supports diverse ways of life. There are an estimated 8.7 million species on Earth, many still unknown, and the current extinction rate is alarmingly high due to human activities. Biodiversity loss leads to less resilient ecosystems and affects their ability to provide essential services.

What are the main benefits of ecosystems rich in biodiversity?
Biodiversity, with its incredible variety of life forms, including terrestrial, marine and aquatic organisms, is the basis for a myriad of ecosystem services essential to our survival. But you may be wondering: what are these vital services? Ecosystems well populated by a diversity of species offer benefits such as water purification, oxygen production and climate regulation, elements without which our existence would be threatened.
For Brazilian ecosystems, genetic diversity means resilience in the face of diseases and environmental changes, enabling the adaptation and survival of species. Each species contributes in a unique way to the productivity and stability of the ecosystem to which it belongs, and the richness of habitats guarantees greater resilience in the face of disasters, supporting diverse forms of life.

Furthermore, there are undeniable economic benefits linked to biodiversity conservation. A tangible example is the pollination service, essential for agriculture and valued at approximately $217 billion per year. We cannot yet disregard the role of biodiversity in preventing diseases and promoting human well-being, attributes that are increasingly relevant in a world where health has become a priority.
The loss of biodiversity, in turn, results in less resilient ecosystems and a decreased capacity to provide these services. For this reason, conservation strategies are fundamental, often including the creation of protected areas and the restoration of ecosystems, sustainable practices and the reduction of greenhouse gas emissions. Public awareness and education about the importance of biodiversity is crucial to driving sustainable behaviors and conservation efforts.
What are the main threats to biodiversity?
The loss of natural habitat is one of the most significant threats to biological diversity. Species threatened with extinction often find themselves at risk due to the unbridled advancement of human impact on biodiversity. Deforestation and pollution appear as preponderant causes regarding the decrease in the number of species.
But what would be the main reasons behind the loss of biodiversity? This includes actions such as the conversion of wild areas into agricultural and urban land, as well as the contamination of ecosystems through toxic waste and environmental degradation.
The consequences of the disappearance of species are profoundly damaging to global ecosystems. For example, plant pollination, essential for agricultural production, is seriously compromised in the absence of certain insects. The extinction of a single species can trigger a domino effect, affecting the stability and productivity of an entire ecosystem and its services.
Climate change represents a major influence on the dynamics of biodiversity. They cause changes in environmental conditions that can exceed the adaptation capacity of several species, leading to an increase in extinction rates.
To deepen this understanding, it is essential to know institutions such as the Chico Mendes Institute for Biodiversity Conservation, who work tirelessly to preserve Brazil's rich biodiversity, minimizing negative impacts and promoting awareness actions regarding the vital importance of conserving our species.
And so, we realize how intricate and indispensable the maintenance of biodiversity is: it guarantees the resilience of ecosystems, which, in turn, provide countless advantages essential to the survival and well-being of humanity.
How can conservation actions protect and restore biodiversity?
Biodiversity conservation is a critical aspect of environmental protection that aims not only to protect existing species and habitats but also to restore those that have been degraded. Effective strategies for biodiversity conservation involve two main approaches: in situ, which occurs in natural environments, and ex situ, outside the natural environment.
Conservation units are protected areas designed to preserve natural resources and biodiversity. They are essential for maintaining native species, protecting ecological functions and enabling scientific research. Ecological corridors, in turn, are areas that connect conservation units, allowing genetic flow between populations of species and the migration of animals, which is crucial for maintaining biodiversity.
In Brazil, examples of successful conservation include the National System of Conservation Units (SNUC) and the work of the Chico Mendes Institute for Biodiversity Conservation (ICMBio) in the management of national parks and reserves. At a global level, areas such as Yellowstone National Park in the United States and the Mesoamerican Biodiversity Corridor have been successful in preserving broad biodiversity and are references in conservation.
With the continuous advancement of human impacts on the environment, such as water pollution, the existence of these protected areas and ecological corridors is more significant than ever. They not only safeguard current ecosystems, but also ensure the health and diversity of future generations, in line with the benefits described in the review summary, such as water purification and oxygen production, which directly depend on the planet's biological diversity.
Biodiversity: essential for ecosystems
Biodiversity, or biological diversity, refers to the enormity and variety of life on our planet. It comprises not only the species themselves, but also the complex web of interactions between them and their environments. But why exactly is biodiversity so vital to ecosystems?
Ecosystems rich in biodiversity provide ecosystem services indispensable. For example, aquatic and terrestrial ecosystems function as great purifiers, maintaining water and air quality. They are natural habitats that promote plant pollination, essential for food production, and regulate the climate, mitigating temperature extremes and severe weather events. This capacity of ecosystems is explained in detail on BiologiaNet.
From an economic point of view, maintaining biodiversity results in considerable financial benefits.
