Is the number of animal species on earth increasing compared to their number in a decade ago?

Answer 1

If you keep in mind all of the species that have gone into extinction I would have to guess it's decreasing.

Answer 2

"The world's species face an unprecedented crisis. The rate at which they are being lost is alarming, even when compared with the extinction episode of 70 million years ago when the dinosaurs disappeared. No-one knows exactly what the current extinction rate is, but recent calculations by leading scientists put it at between 1,000 and 10,000 times greater than it would naturally be. The rate of extinction also appears to be increasing."

Keep in mind that we don't even know how many species are out there. Odds are you can go out in the ocean, scoop up some water, and find a new species of bacteria.

Answer 3

The number of animal species on earth has in fact dwindled compared to thier number a decade ago. So many animal species have been extinked.

Answer 4

It's virtually impossible to accurately count animal populations because the simple act of counting them disturbs them and causes them to move. This is especially true with small creatures, such as insects. When we claim an animal is extinct, all that means is that we have not seen any in a long time. Maybe they ARE all gone, or maybe there are some hidden in a jungle in Africa.

In the same way, there are countless species of plants, animals and fungi that have yet to be discovered.

With no accurate baseline data on how many of a given species there are, or even how many species exist, how can one begin to project statistics on population growth or loss?

No, it cannot be accurately counted. Never in a million years.

Answer 5

No, but I doubt that the number of extinctions is really significant relative to the number of species. The problem is the extinctions occur among large animals in places people live so that they are very visible to us. Too bad small life forms like HN51 virus and Aids virus don't go extinct.

Answer 6

Species have been extinct, there is no more dinosaurs! Also more people die from aids now a child dies every three seconds, three have died when I've wrote this, its really sad isn't it, so that's why i think we should get rid of world poverty! and also we should have a national aids day where we donate money to aids. Please spreas the word to the world, and tell people the Pink Bannana is helping!
The answer to your question is no, there are less species around today.

Answer 7

Animal species are increasing. Think not only dinosaurs & mammoths, but SOME viruses & bacteria that are classified as animals. Lots of new diseases are on this earth because of those tiny colonizers! They are mutating & expanding. Be very wary about the bird flu if it strikes in India or China where there are few means to combat this plague, we will all die because of billions of people will die there, that's why my friend in Dubai is checkin on this & US is very vigilant on this, not the war on terror. Are you ready to be colonized by them?

Answer 8

Actually there are new species being born along with some species being extinct.So net change i feel the species are getting decreased day by day at present.

Answer 9

yes it is true compared to days before,today tigers,lions leopards,gorillas,pandas,etc., which were mainly in the list of extinction are recovering slowly and their numbers are increased respectively in these days.a good question and concerns towards nature are apppreciable keep it up going .such acts are rewarded not by money or any other price it will be rewarded in future by nature

Answer 10

No, some species are getting more and more extinct.
