Dead as a Dodo.

Things do have a habit of becoming extinct, just think about the Dinosaurs and all the prehistoric life that went with them including many plants. Extinction is caused by one or many factors such as climate, disease, changes in sea level and of course asteroids. The sad fact is though that now we humans are fast tracking species extinction on a massive scale. By destroying habitats, pollution, over harvesting, global warming and illegal trafficking of species for profit. You can not just recreate a species from DNA and reintroduce it. Science is not able to do that yet and by the time it does, chances are that it will not have enough habitat left to live in. Wildlife parks are brilliant but animals very often need to travel vast distances to migrate or to simply keep their gene pool diverse. These parks are always running a war against poachers and the rarer the creature the higher the price on its head. A high price means people are willing to take bigger risks. Schools now cover rare species in their curriculum and my own son has been telling me all about the White Rhino he is studying in primary school. But let's go smaller and look pass the large mammals, endearing Pandas and fantastic Mountain Gorillas, lets look at the tiny invertebrates. At present one fifth of the world's invertebrates are at risk. That might not sound much until you realize that invertebrates make up around 80% of all animal life. They are the foundation of ecosystems all over the world. For us they recycle waste, pollinate, purify water and keep soils productive. We should do well to remember that.

The remains of mummified Dodos being preserved for science and to remind us that extinction is happening on a large scale in our lifetimes. Now caused by the impact of our species, not an asteroid.
