Biodiversity, also known as biological diversity, reflects the variety of life on Earth. This variety encompasses different levels, from genetics through species and ecosystems. Biodiversity underpins the health of our shared planet and has a significant impact on our lives. Indeed, biodiversity is crucial to our food supplies and has an effect on the ability of farmers, fishermen, and livestock keepers to produce food as well as other goods and services. In other words, the decrease in biodiversity can result in a future where fresh water supplies are irregular and scarce, and where food supplies are more vulnerable to pests and disease. Scientists predict that by the year 2050, more than 25% of species on Earth will be threatened with extinction by climate change alone.
