primate ecology discussion is the cup half full or half empty

Of the nearly 600 species and subspecies of primates living today approximately half are in danger of extinction. The number of recognized serious threats to primate survival has increased over the last decade. they include climate change, habitat loss ( encroaching farmland, deforestation, logging industries). and bushmeat hunting. Also, primate diseases, particularly for those populations that are in danger of contracting diseases from exposure to humans through ecotourism is on the rise. How have your perceptions of these threats changed, and reflect on whether the situation is hopelessly grave (the cup half empty) or there are reasons for optimism (the cup is half full).

Please no plagiarizing, but this is just a discussion post so the more info the better!
