These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true - i.e. that there are around 2 million different species on our planet** - then that means between 200 and 2,000 extinctions occur every year.

Climate change is accelerating the sixth extinction World biodiversity has declined alarmingly in half a century: more than 25,000 species, almost a third of those known, are in danger of disappearing. Climate change will be responsible for 8% of these.

As of 2016, the number of critically endangered species in the UK reached 165. With the significant drop in the abundance of its wildlife, the UK is now considered “one of the most nature-depleted countries in the world”.

In the past 500 years, we know of approximately 1,000 species that have gone extinct, from the woodland bison of West Virginia and Arizona's Merriam's elk to the Rocky Mountain grasshopper, passenger pigeon and Puerto Rico's Culebra parrot — but this doesn't account for thousands of species that disappeared before ...

In June 2019, one million species of plants and animals were at risk of extinction. At least 571 species are lost since 1750 but likely many more. The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.
