Whole "chunks of life" are lost in extinction events, all at the same time. If related species are threatened, you may be too (since primates are endangered, what does that say about humans?)
In BBC News, Victoria Gill quotes biologist Richard Grenyer as saying, "Big groups of organisms tend to be similar to one another. Look at the...
Scientists don't agree on how many mass extinction events in earth's history were triggered by a space rock crashing into the planet's surface. However, most do agree that an asteroid collision 65 million years ago (among other things) was what brought an end to the age of dinosaurs. The outer planets Saturn and Jupiter protect us from many of...
Biologists warn that global warming and the destruction of natural habitats will lead to significant declines and extinctions in the world?s 8,750 terrestrial bird species over the next century. In Scotland, they're already noticing the disappearance of seabirds. It's the middle of their breeding season, but the cliffs where there should be...
Many things can cause a species to disappear: including poaching (for food or medicine) and habitat destruction. It turns out that one of these things is NOT war.
Aerial surveys by the Wildlife Conservation Society confirm the existence of more than 1.2 million white-eared kob, tiang antelope and Mongalla gazelle in Southern Sudan, where...
UPDATE - All over the earth, animal species are going extinct at an unprecedented rate. Orangutans were once known as the "old men of the jungle," because they behave so much like humans. Now they may disappear as well. But the very LATEST victim is the Chinese tiger which, like so many others, is being exploited for use in...
Are we next? - Genetically modified plants, such as Starlink corn, arealmost all produced by Monsanto. They are usually engineeredto be resistant to Monsanto's pesticide Roundup. This meansthat entire fields can be sprayed with Roundup and the weedswill die but the GM plants will survive. This sounds like agreat idea, except...
The fossil records tell us that there have been severalmassive extinction events in the life of the Earth. We nowknow the reasons for some of them?for instance, thedinosaurs were wiped out by an asteroid that broke intopieces upon impact, producing dust which blocked the lightof the sun. Recently, a consistent 62 million yearextinction cycle...
There have been five mass extinctions on the Earth in the past four billion years, and the last one 65 million years ago wiped out the dinosaurs. Biologists have long speculated that if humans become extinct, insects will become the next dominant species. Now they say we're about to have a sixth extinction, but it won't be the end of us?not yet...
Almost half of all plant species are facing extinction. Earlier, the World Conservation Union thought only one in eight plant species would disappear, but now it looks like we'll lose half of them, and some researchers think we?ll lose even more. Most of the medicines used in the West were discovered in tropical forests, which are being cut...
Scientists think we may be in the middle of the sixth massextinction in the history of the Earth. A UN report warnsthat 1,183 (12%) of bird species and 1,130 (nearlyone-fourth) of all mammal species are threatened withextinction.
Mass extinctions have occurred five times so far in the fourbillion year history of life on Earth. These are...
