INTRODUCTION

The extinction of species is not just a tragedy for living beings, but a serious problem that affects biodiversity, the ecological balance of the planet and our survival. With the increase in human activity, species are facing ever more dangerous threats, and this is causing us to reflect on the importance of preserving wildlife.

IMPORTANCE OF BIODIVERSITY

Biodiversity is essential for the functioning and balance of all the planet's ecosystems. It plays an important role for humans, as it is used as a source of food, energy and raw materials. However, despite knowing its importance, we are also responsible for its destruction.

MAIN CAUSES OF THREATS TO SPECIES

• Habitat destruction;
• Overuse of natural resources;
• Introduction of invasive species;
• Changes in land use (e.g. deforestation);
• Direct exploitation (e.g. hunting or overfishing);
• Climate change;
• Pollution.

IMPACTS OF EXTINCTION ON THE ECOSYSTEM

• Loss of biodiversity;
• Reduction of the planet's global gene pool;
• Reduction in the number of natural resources and food variety;
• Reduction in the self-regulating capacity of ecosystems;
• Increased extinction of other species.

PROTECTIVE MEASURES TO ADOPT IN THESE CASES

• Reforestation of forests and natural spaces;
• Avoid contamination;
• Respect protected areas and natural parks;
• Combat the trafficking of exotic animals and excessive hunting.

CONCLUSION

To conclude, the preservation of endangered species is extremely important for maintaining the planet's ecological balance and varied biodiversity. That's why we need to act now to ensure a sustainable future for generations to come.
