How does defaunation impact ecosystem services?

Defaunation, the loss of animal species, can have serious impacts on ecosystem services crucial for maintaining ecological balance and supporting human well-being. One of the key ecosystem services affected by defaunation is pollination. Many animals such as bees, butterflies, and birds play a vital role in pollinating plants, which is essential for the reproduction of crops and wild plant species.

Another important ecosystem service disrupted by defaunation is seed dispersal. Animals like birds, mammals, and insects help disperse seeds, promoting plant diversity and the health of ecosystems. Without these animal species, the natural regeneration of vegetation becomes compromised.

Additionally, defaunation can disrupt nutrient cycling in ecosystems. Animals play a crucial role in transferring nutrients through the food chain and promoting decomposition processes. Their absence can lead to imbalances in nutrient cycling, affecting the overall health and functioning of ecosystems.

The importance of preserving animal populations

It is essential to prioritize biodiversity conservation and wildlife preservation to safeguard ecosystem services. By protecting animal species and their habitats, we can support healthy ecosystems, ensure food security, and promote environmental health for present and future generations.
