Poachers kill animals without first thinking about whether they are endangered or not. We humans need to learn to have land and set aside land for animals as well. People just take what they want and then they forget completely what they destroyed, and how that might impact the life of an animal.
Poachers don't care if something is endangered or not. More people need to be in the field searching for them, and penalties need to be much stiffer for those that get caught so that the risk/reward isn't as appealing as it currently is for people in so many poor countries.
Once a species of animals has died off, there is no way to bring them back. This is an important thing to realize because as our technology becomes more sophisticated, we will come to realize how useful some animal species can be in our lives. Certain endangered species, especially the ones in the rainforests, must be protected for the betterment of society.
I do not understand why so much effort is being directed at animals when there is so much human suffering in the world. Humans should look out for other humans first not some animal. If all the money that goes towards animal rights and habitats were spent on people the world would be much better off.
