Many years ago, women and African Americans were considered to be property under the law - equivalent to a chair, a table, or a tree.
Once in a great while, a white male (a "person") would, on behalf of the "thing" (African American or woman) ask the court to allow a Habeas Corpus Common Law ruling to take effect - making that individual "thing" a "person" under the law. Now this only works for individuals, not the whole black or female population.
The Global Conservation Group would like to apply this same concept to animals. Since animals are considered "property" under the law in the United States (even though they have the same ability to feel pain, emotions, and the desire to live as humans do), they can't represent themselves in court. So a "person" - any human being, can bring this court motion on their behalf.
The GCG plans to file these court motions in a local court first, if that fails (as it likely will), the next step would be asking the State Supreme Court, and if that also fails, the final step would be to petition the United States Supreme Court to take on this case! If we are successful, this may lead to the "personhood" of animals under the law.
Animals are not chairs, tables, or trees - and they should not be treated as such under the law. They are living beings and it's about time they deserve some basic rights.
