Why is the conservation of biodiversity so important?
Biodiversity, i.e. the richness of nature, is perhaps the most important asset on our planet. Plants, animals, fungi and microorganisms purify water and air, serve as food and medicine and ensure fertile soil and a pleasant climate.
What influence does climate change have on biodiversity?
Climate change will change the ecosystem significantly and above all harbors two risks for biodiversity: On the one hand, it happens faster than many species can genetically adapt or migrate with the temperature shifts. Species that can cope better with these conditions have an advantage.
Why is species diversity important?
They kill animals or build lots of roads or houses so that animals no longer live there and plants can no longer grow there. We bring so many fish out of the sea that some species are in danger of disappearing there too. The researchers are now sounding the alarm because biodiversity is an important issue.
What does biodiversity mean in simple terms?
Biodiversity encompasses the various forms of life (species of animals, plants, fungi, bacteria), the different habitats in which species live (ecosystems such as forests or bodies of water), as well as the genetic diversity within the species (e.g. subspecies, varieties and races).
What is biodiversity explained to children?
Biodiversity means something like the diversity of all life on earth. Scientists estimate that 150 animal and plant species become extinct every day – and thus disappear from our earth forever.
What is biodiversity?
The three areas of biodiversity, also known as biological diversity, are closely linked: the diversity of species, the genetic diversity within species and the diversity of ecosystems, to which communities, habitats such as forests and seas and landscapes belong.
What is biodiversity?
Species diversity is a partial aspect of biological diversity (biodiversity). Biodiversity is also understood to mean the genetic diversity within and between species as well as the diversity of ecosystems and landscape regions.
What is biodiversity?
Species diversity, also known as species diversity, is a measure of the diversity of biological species within a habitat or geographical area and thus of the diversity of flora and fauna. It is a measure of the characterization of the biodiversity of an area.

How many species of mammals are there in the world?
At the beginning of 2018, 6399 recent species were distinguished worldwide. The mammals are divided into three subclasses: the egg-laying mammals (Protheria), the marsupial mammals (Metatheria) and the higher mammals or placentas (Eutheria), which also include humans.
How many living things are there in the whole world?

What are the most animals in the world?
4.4 times 10 to the power of 20 – that corresponds to 57 billion individuals per person: Roundworms are the most common animals on our planet, according to an inventory. The total biomass of the tiny soil dwellers corresponds to around 300 million tons.
Where do most of the animals live in the world?
Hotspots for newcomers: For the first time, researchers have determined where in the world most imported or introduced animal and plant species are to be found. Hotspots for bio-invaders are therefore on Hawaii and the North Island of New Zealand, but also on the coast of Florida.
In which country are the most animals?
Which animals live in China? China is one of the countries with the most animal species. 10 percent of all species on earth live in China. Of these, more than 2,400 animal species can be found on land and almost 4,000 in water.
How many animals are there in the world in 2019?
It is estimated that there are around five to 50 million animal species. In total, that makes about a trillion animals. A trillion, that’s a one with 18 zeros, so 1. Most of them are insects and microorganisms.
