The total number of rare earth elements is View Solution Assertion : About the total number of species present on earth some extreme estimate range from 20 to 50 million. Reason : We have no clear idea of how many species are yet to be discovered and described. ...
Today, such records of biodiversity are often in the form of photos, e-mails and other digital records. Though they are useful for identifying shifts in the number and variety of species on our earth, a new standardized study has found that this type of record is not perfect."With the ...
The millions of species on our planet make up Earth's biodiversity(生物多样性), which keeps ecosystems(生态系统) in balance. But as humans put increasing pressure on the planet, we risk losing biodiversity. Plant and animal species are now being lost at the fastest rate in 10 million years...

Thanks to the desertification prevention efforts by Chinese enterprises in Kubuqi Desert, a significant increase has been achieved in forest and vegetation coverage, the number of species surged from less than 10 to 530, and over 100 wildlife species that were believed to have disappeared re-...
In the race to document the species on Earth before they go extinct, researchers and citizen scientists have collected billions of re-cords. Today, most records of biodiversity are often in the form of photos, videos, and other digital records. Though they are useful for de-tecting shifts in...

on 89% of all variables (Fig.2b). CAMS outperforms Aurora on ozone in the very upper atmosphere and the 12-h prediction of all species in the lower part of the atmosphere. Aurora generates these predictions in approximately 0.6 s per hour lead time on a single A100 GPU. This yields...
