Biodiversity, water, soil, and clean air are essential to people’s health, food, and well-being, which is why they are part of what we call ecology.
Ecology studies the relationships between living beings and the environment in which they live. Its knowledge helps us understand how human activities influence ecosystems and why it is fundamental to curb pollution, biodiversity loss, and climate change.
Protecting nature also means safeguarding our quality of life. Forests sequester carbon dioxide, help regulate temperature, and contribute to water conservation; pollinators, for their part, play an essential role in producing many foods. Likewise, green spaces promote well-being and help reduce heat effects in cities.
World Ecology Day 2026 invites us to review our habits and opt for responsible consumption, reduce waste, save water and energy, and support the conservation of natural spaces. It also highlights the importance of promoting sustainable production models.
Taking care of the planet is not something detached from our daily routine: it is a way to preserve resources and ensure a healthier future for the generations to come.
What is ecology?
Today, November 1st, is the World Ecology Day 2026, a meaningful date that aims to raise awareness and sensitize people to the necessity of protecting and preserving the environment and the planet’s biodiversity, as well as to recognize the importance of Ecology as a discipline and the work that ecologists undertake.
It is the study of the interactions that exist between human societies and their surroundings. By studying these behaviors, we can minimize our impact. Remember that the planet is a vast ecosystem that must maintain the balance of the countless sub-ecosystems that compose it. Each element is necessary for the others to subsist.
The origin of ecology
The concept of ecology was coined in 1866 by German biologist Ernst Haeckel during the Industrial Revolution. The rapid development of societies already raised questions about the sustainability of this new model. With the concept of ecology, the scientific community began, as early as the nineteenth century, to question the habitability of a post-industrial planet.
Its usage became widespread more than a century later, in response to social concerns raised at the Stockholm Summit and, above all, at the Rio de Janeiro Climate Summit of 1992, organized by the United Nations (UN).
At the Rio summit, a global program to combat climate change, deforestation, and the use of toxic products was launched. Since then, the concept of ecology has been linked to local, national, and international government policies.
The growth in its use is almost simultaneous with the emergence of the concepts of sustainable development and biodiversity, which arose in the 1980s and whose use has been enhanced over time with the advancement of communications and the internet.
Why do we need to protect our ecosystems?
Currently, the planet is facing two major ecological crises that threaten its habitability: the accelerated loss of biodiversity and an unstoppable rise in temperatures, known as global warming.
The exploitation of fossil fuels by human activities since the Industrial Revolution has led to a concentration of greenhouse gases in the atmosphere, which in turn exacerbates global warming by intensifying the so-called greenhouse effect.
And as the planet’s temperature rises, the impact on its livability grows: a clear example is the recurring climate disasters such as hurricanes reaching speeds like 295 kilometers per hour, exemplified by Melissa, floods, and heat waves, as well as desertification and a shortage of drinking water.
On the other hand, the diversity of species is essential to maintaining enough resources for all living beings. If insects disappeared, pollination of plants and soil fertility could not be assured, compromising global food sovereignty.
Similarly, plant diversity guarantees the natural filtration of rainwater and is a source of oxygen, food, medicinal plants, and much more. Deforestation, among other things, endangers biodiversity by destroying the natural habitats of plants and animals.
That is the main objective of ecology: to guarantee the planet’s habitability and the availability of sufficient resources so that everyone can live there. And on World Ecology Day 2026 it is essential that as many people as possible understand this necessity and actively participate to achieve this goal.
The ecological transition toward green growth
Currently, the planet is undergoing two major ecological crises that threaten its habitability: the accelerated loss of biodiversity and an unstoppable rise in temperatures, known as global warming.
The ecological transition is a key idea that should be highlighted on World Ecology Day 2026. It involves rethinking how we consume, produce, and coexist within a framework of sustainable development that allows all inhabitants of the planet to effectively address current environmental challenges.
This requires a transition to a new economic and social model where the systems we depend on—such as transportation, electricity generation, infrastructure construction, and even leisure—have the least possible impact on the environment.
Pollination helps quantify that dependence. According to the IPBES assessment released by the United Nations, about 75 % of the major food crops depend, at least partially, on animal pollination, as does nearly 90 % of flowering wild plants. Protecting bees, butterflies, and other pollinators, along with their habitats, therefore has a direct consequence on food production. Ecology helps us understand these relationships and guide their conservation before species loss compromises essential functions.
