Did you know that simple daily actions can help save the planet? From bringing a reusable tumbler, planting native vegetation, to reducing plastic waste, these small habits can create a significant impact on the sustainability of biodiversity.
The International Day for Biological Diversity (IDB) 2026 carries the theme “Acting Locally for Global Impact.” This theme serves as a reminder that biodiversity conservation does not always have to begin with large-scale actions. In fact, simple actions carried out consistently by many people can create meaningful environmental change.
Currently, global biodiversity faces various serious threats, such as habitat loss, environmental pollution, climate change, and pressure from human activities. Indonesia is recognized as one of the countries with the highest biodiversity in the world. Approximately 1.75% of the world’s species are found in Indonesia, including its rich flora, mammals, reptiles, birds, and coastal ecosystems such as coral reefs and marine biota. However, Indonesia also faces serious threats to biodiversity, with hundreds of species recorded as endangered.
Why is Biodiversity Important?
Biodiversity as a Life Support System
Biodiversity plays an important role in maintaining ecosystem balance. Various living organisms in nature are interconnected and support one another within the chain of life. Plants produce oxygen and serve as food sources, insects assist the pollination process, while forests and oceans help maintain climate stability and water cycles.
In addition, biodiversity is closely related to basic human needs, such as food, clean water, health, and the economy. Many food sources, medicines, and livelihoods depend on the existence of healthy ecosystems. Therefore, protecting biodiversity also means protecting human quality of life itself.
The Impacts of Biodiversity Loss
The loss of biodiversity can trigger various negative impacts on the environment and human life. Indonesia is also ranked as the sixth country with the highest level of biodiversity extinction. This was conveyed by the Deputy for Life Sciences at the Indonesian Institute of Sciences (LIPI), Prof. Dr. Enny Sudarmonowati. The decline in species populations and ecosystem degradation can reduce environmental quality, such as decreasing clean water availability, increasing pollution, and damaging soil fertility.
Furthermore, biodiversity degradation also increases the risk of ecological disasters, such as floods, landslides, coastal abrasion, and droughts. In the long term, these conditions can affect the economic sector and community welfare, especially for groups that depend directly on natural resources.
Simple Actions that Can Be Taken in Daily Life
Reducing Single-Use Plastic
Plastic waste has become one of the greatest threats to terrestrial and marine ecosystems. Plastic, which is difficult to decompose, can pollute the environment and endanger wildlife, especially marine organisms that often mistake plastic for food.
Simple actions that can be taken include bringing a reusable tumbler, using reusable shopping bags, and reducing the use of single-use packaging. These small habits can help reduce the amount of plastic waste that ends up in the environment.
Planting and Caring for Native Plants
Planting native plants at home or in surrounding environments is also a simple contribution to biodiversity conservation. Native plants are generally more adaptable to local environmental conditions and can support pollinators such as butterflies and bees.
Examples of native woody plants that can be planted include ketapang kencana, tabebuya, trembesi, tanjung, bintaro, and pucuk merah. In addition to providing shade, these plants help absorb carbon, maintain air quality, and serve as habitats for birds and insects.
At the household level, communities can also plant productive trees such as mango, guava, rambutan, or citrus trees in their yards. Meanwhile, flowering plants such as butterfly pea flowers, jasmine, and hibiscus can help attract pollinating insects. Besides beautifying the environment, the presence of native vegetation also helps reduce heat, absorb rainwater, and create greener, healthier, and more comfortable spaces.
Saving Energy and Water
Excessive use of energy and water can increase pressure on natural resources. Therefore, conserving energy and water is a simple step that can create a major environmental impact.
Several habits that can be applied include turning off electricity when not in use, using water wisely, and choosing more environmentally friendly transportation, such as walking, cycling, or using public transportation.
Supporting Sustainable Products and Practices
Communities can also contribute through their daily consumption choices. Choosing local and environmentally friendly products can help reduce carbon footprints while supporting more sustainable production practices.
In addition, supporting businesses that implement sustainability principles is also a form of participation in encouraging broader environmental protection.
The Collective Impact of Small Actions
Biodiversity conservation is not only the responsibility of governments or certain communities, but also the responsibility of all members of society in maintaining the sustainability of the planet for future generations. Major changes often begin with small, consistent actions.
Although they may seem simple, individual actions can create a domino effect that influences the surrounding environment and encourages behavioral change at the community level. The more people adopt environmentally friendly lifestyles, the greater the positive impact on biodiversity conservation.
