Biodiversity is rapidly declining worldwide, and there is considerable evidence that ecosystem functioning (e.g., productivity, nutrient cycling) and ecosystem stability (i.e., temporal...
Biodiversity has declined by more than a quarter in the last 35 years. The Living Planet Index (LPI) shows a decline of 52 per cent between 1970 and 2010. That's not good news. In general terms, population growth and our consumption are the reasons for this enormous loss.
WWF’s 2020 Living Planet Report held some alarming news: The world has seen an average 68% drop in mammal, bird, fish, reptile, and amphibian populations since 1970. Much of the loss is caused by habitat destruction due to unsustainable agriculture or logging.

Nature loss has far-reaching consequences. Damaged ecosystems exacerbate climate change, undermine food security and put people and communities at risk. Around 3.2 billion people, or 40 percent of the global population, are adversely affected by land degradation.
