Quelles solutions reste-il pour sauver la biodiversité ?

The Alarming State of Biodiversity

Overview of the Biodiversity Crisis

• A report by hundreds of scientists warns that one million animal and plant species are at risk of extinction in the coming years.

• Franck Courchamp, a biodiversity specialist, highlights that 75% of terrestrial environments and 66% of marine environments are severely altered due to human activities.

Major Causes of Biodiversity Loss

• The five main human-driven causes for biodiversity loss include:

• Habitat destruction (deforestation, marine habitat destruction)

• Invasive species introduction

• Pollution

• Climate change

• Overexploitation of species

Urgency for Action

• The UN report suggests there are solutions to prevent this catastrophe but does not specify how much time is left to act.

• Unlike climate issues, biodiversity can rebound quickly if pressures from human activities cease; however, some species and ecosystems may already be too late to save.

Examples of Irreversible Losses

• Certain species like the Pyrenean ibex and the northern white rhinoceros have already gone extinct or are on the brink with only two females remaining.

• Sensitive natural habitats such as Amazon forests could transform into savannas due to climate change; wetlands have seen an irreversible loss of 83%.

Proposed Solutions for Governments

• Immediate actions suggested include:

• Enhancing education about biodiversity for future generations.

• Ceasing financial support for programs detrimental to biodiversity (e.g., fossil fuels, intensive agriculture).

Economic Considerations in Transitioning Practices

• Stopping subsidies for harmful practices may create short-term tensions but will ultimately lead to less severe environmental crises compared to maintaining current practices.

Role of Citizens in Biodiversity Preservation

• Citizens can contribute by changing consumption habits:

• Reduce packaging waste and palm oil usage (a major deforestation driver).
