False. Animals were made the same day as man!!!!!
The above is true if you believe exclusively in creationism. Science says that all the species of animals that live on earth today make up less than one tenth of one percent (0.1%) of all the animals that have ever existed. So to answer your question: yes, many species became extinct before mankind altered the earth.
True A+
The first life on earth was unicellular organisms. These organisms reproduced asexually, meaning that they reproduced by copying themselves. Because they did not interbreed, a slight mutation in the DNA caused a new species to exist. If one of the mutant cells failed to divide, that was a species becoming extinct. Humans cannot even begin to fathom the number of these species there must have been or when they started to become extinct. Extinction is a natural process and cannot be stopped; when we talk about being concerned about extinction we generally mean extinctions caused by modifications made to the environment by humans.

Life started in the oceans and seas.
The undisturbed rainforest started to become disturbed . thats how they became extinct. :DD
The American Bison is an endangered species, and is NOT extinct. There are about 300,000 left and most are on farms for breeding. During the late 1800's many settlers started killing them for food and for sport. But the settlers didn't use all of the animal like the Indians, but used barely anything.
It has existed since mankind started living in groups.
Poachers were hunting them down for their valuable tusks.
Rhinos started to become extinct after too many poachers started killing them for their horns.
Finland.
like what the first person said it all depends on the zoo a lot more animals would be extinct like the whit rhinos they are trying to keep that species alive so don't anybody get me started o the argument.
If water becomes polluted, certain species will get sick such as fish. Once they get sick, They will start to die off. If they go extinct, animals that eat that fish, will suffer because lack of food. And the system goes on. The animals that eat the fish die off and and their predators will suffer. Such as the rabbit incident in Australia. All the grass was extinct and other herbivores started to suffer. Causing mass extinction upon species.
