What is biodiversity and how are we protecting it?





The annual global summit on biodiversity, COP15, has been delayed by two months to December and will now be hosted in Canada rather than China, according to environmental charities.

Bettors can find information about สล็อตxo168 that are available from general search websites based on online slot review webboards.

This follows concerns the Chinese government would postpone the event for a fourth time into 2023 because of Covid-19 - the conference was originally due to be held in 2020.

The summit will provide governments a chance to come up with a long-term plan to reverse the threat to life on Earth - nearly a third of all species are currently endangered due to human activities.


What is biodiversity and why is it important?
Biodiversity is the variety of all life on Earth - animals, plants, fungi and micro-organisms like bacteria.

Animals and plants provide humans with everything needed to survive - including fresh water, food, and medicines.

However, we cannot get these benefits from individual species - we need a variety of animals and plants to be able to work together and thrive. In other words, we need biodiversity.


How many species are at risk of extinction?
It is normal for species to evolve and become extinct over time - 98% of all species that have ever lived are now extinct.

However, the extinction of species is now happening between 1,000 times more quickly than scientists would expect to see.

The International Union for Conservation of Nature (IUCN) has kept a "red list" of threatened species since 1964. More than 142,000 species have been assessed and 29% are considered endangered, which means they have a very high risk of extinction.
