Species Eracication, same as a holocaust?

In the past there have been several animal holocausts and they still continue today.  They have and always will take many forms.  There are laws in place now to help prevent some of the methods of destroying a certain animal or breed such as poaching laws, but many times they are poorly enforced and not all laws made work to protect the animals that are being harmed.  For example, for a very long time Rottweilers were discriminated against as a breed of dog.  It was either completely or nearly illegal to own them in many areas.  This didn't happen because the breed's genetics are flawed in a way that makes them vicious, but because they blame the dog breed that happens to be the current favorite of criminals and other sorts that don't do the breed justice.  Some people intentionally mistreat their dogs in ways that make them more aggressive.  Why then did and does society and law makers blame the breed?  The answer is because it is easier to kill or outlaw all dogs that look like they may be a particular breed than it is to hunt down the humans that turn these beautiful creatures into the vicious monsters that they can be when they are neglected.  There are several other breeds that are subjected to this injustice as well, the American Pit Bull Terrier, the Chow, the Doberman Pinscher, the Siberian and the Alaskan Huskies, and the German Shepard just to make a few.  About this, I say make the laws for the people who do wrong and stop adding more cruelty to the lives of already mistreated animals.  We also need to find a way to crack down on other ways that humans manage to eradicate different species and breeds of animals such as poaching.  I realize that while the United States may be one of the world's superpowers that in many places we are not all that well liked, but that just means that for the safety of our planet we need to use our position in the world to do good for everyone.  The extinction of one species can completely change an entire ecosystem, and that can lead to things far down the line being affected.  Let's say that there is a bug that lives close to the equator and there is a particular bird that eats that bug when it migrates south for the winter.  Now let's say that the bug is almost completely killed off and only about half of the birds learn to eat something else, the other half die from starvation because they were reliant almost completely on that bug for their nutrition.  When the birds migrate back north for the summer, they have predators in a completely different area of the world from where the bug was at.  Now those animals are going to be more hard pressed for food and many of them may die.  Let's say that one of the animals that preyed on this particular bird was coyotes.  Now they are going to diminish in population or find something else to eat.  If they find something else to eat, that may consist of peoples pets that are left outside.  Then there will be a problem with people hunting them due to the fact that they are trying to protect their pets.  Now the population of the species is definitely in danger.  Once the population starts to drop, there will be several farmers whose crops suffer because there will be fewer coyotes to kill off the rabbits and groundhogs and other animals that tear up the crops, so then human consumption will also suffer.  Human meat supply could also suffer when the coyotes are trying to find other food supplies because pigs and cattle that are penned up are easier to hunt and it doesn't take much for a pack to take down a full sized cow.  This could also lead to decreased dairy cattle as well.  The moral of this hypothetical is that we need to think of how it effects the entire world and population there of before we decide to let a species or breed of animal die off completely.  As one of the superpowers our officials can bargain with the officials from countries where poaching is the biggest problem and make them want to crack down and enforce their laws more.  We need to do what is necessary to save what we have left of the planet and maybe extend the life of it as much as we can for future generations of our families.
