I want to know the answer to the following question:
How many species are currently listed?
All the background I'm provided with is that "Opponents of the Endangered Species Act argue that with over 2,000 endangered species listed, and only 28 delisted due to recovery, the success rate of 1% over nearly three decades proves that there needs to be serious reform in their methods to actually help the endangered animals and plants.". Is that enough to answer the question?
