18 October: what is celebrated today

World Nature Protection Day

World Nature Protection Day, observed every 18 October, seeks to raise awareness of the urgency of caring for the Earth. This observance began in 1972, inspired by a speech by former Argentine president Juan Domingo Perón, who warned of “humanity’s suicidal march” towards environmental destruction due to pollution, consumerism and the indiscriminate use of natural resources.

His words, sent to the then UN Secretary-General Kurt Waldheim, planted a seed that would germinate in the sustainability principles of the 2030 Agenda. Although it is not an official United Nations date, this day has become a symbol of ethical commitment to the planet.

Protecting nature is not an option; it is a vital necessity. We are part of the same system that we are damaging, and only by preserving it can we guarantee our own future.

World Menopause Day

Also every 18 October, the International Menopause Society (SIM) and the World Health Organization (WHO) commemorate World Menopause Day, established in 2000.

The aim is to educate and support women during this natural stage of life, which worldwide affects more than one billion people over the age of fifty. Menopause should not be seen as an ending, but as a transition that requires information, specialised medical care and comprehensive wellbeing.

Speaking openly about it helps to break down taboos and foster a healthier, more empowered view of this stage, which is as natural as any other in the female life cycle.

European Day against Trafficking in Human Beings

18 October also remembers one of the most serious violations of human rights: human trafficking. Since 2007, on the initiative of the European Commission, the European Day against Trafficking in Human Beings has been observed in order to make visible and combat this modern form of slavery.

According to recent data, 75% of victims in the European Union are women and girls, and around 25% are minors. Victims are exploited for labour or sexually through deception, coercion and fear.

This day is a call to action: strengthen laws, support victims and, above all, break the silence that protects traffickers. No person should be reduced to merchandise. Freedom is not a privilege; it is a right.

International Sloth Day

The third Saturday in October has a distinctive and endearing protagonist: the sloth. This celebration began in 2010 during the First International Meeting on Sloth Welfare and Conservation, in Medellín (Colombia).

Far from being a symbol of slowness, the sloth represents balance and adaptation to its environment. This day seeks to raise awareness of the importance of respecting its natural habitat and avoiding the illegal trafficking and domestication of wild animals.

Protecting the sloth means protecting the rainforest it inhabits, the trees that oxygenate the planet and the delicate balance of tropical ecosystems.

World Repair Day

In a society dominated by fast consumption and disposal, the third Saturday in October also marks World Repair Day, an initiative that invites us to change the way we relate to technology and everyday objects.

The movement promotes the right to repair: access to spare parts, manuals, software and tools that make it possible to extend the useful life of devices. Repairing, rather than replacing, not only reduces waste and emissions, but also restores value to manual work and sustainability.

Repairing is an act of resistance against the culture of disposal. It is telling the planet that we still believe in the possibility of making amends, putting things back together and caring for what sustains us.

A day to care for what matters

18 October reminds us that every action, however small it may seem, can make a difference: caring for a forest, listening to a woman, rescuing a victim, protecting a species or repairing an object. They are all ways of healing the bond between human beings and their environment. Ultimately, protecting nature, life and dignity is the most urgent—and noblest—task of our time.
