Species eradication for ecosystem restoration.

Area of Science:

• Ecology
• Environmental Science
• Conservation Biology

Background:

• Ecosystems globally are under severe stress due to escalating human pressures, including agriculture, resource extraction, and development.
• Human-induced climate change exacerbates ecosystem degradation, affecting even remote terrestrial and marine environments.
• Impacts range from ecosystem collapse and species replacement to novel ecosystems formed by range shifts.

Purpose of the Study:

• To highlight the critical state of global ecosystems under anthropogenic stress.
• To underscore the importance of ecosystem restoration efforts.
• To align with the United Nations Decade on Ecosystem Restoration (2021-2030).

Main Methods:

• This abstract synthesizes current understanding of ecosystem stressors and degradation.
• It reviews the observed ecological changes and their drivers.
• It frames the context for global restoration initiatives.

Main Results:

• Human activities are the dominant drivers of ecosystem change and degradation worldwide.
• Climate change amplifies these pressures, leading to significant ecological shifts.
• Ecosystems are experiencing collapse, replacement, and novel species assemblages.

Conclusions:

• Reducing human pressures is essential for ecosystem survival.
• Ecosystem restoration is a critical global priority to counteract degradation.
• The UN Decade on Ecosystem Restoration provides a framework for action.
