Unit 6: Human Practice of Science - Discussion Not only have humans, like all other living creatures had to make adaptations, changes and adjustments to survive and thrive, but we have had a profound impact on the lives of other creatures on Earth. Sometimes this has been a beneficial impact, but in many cases, it has been a disaster for the other creatures. Do some background reading about the extinction of the passenger pigeon at The Smithsonian: . The extinction of the passenger pigeon is an event that is very easily attributed to the activities of humans. However, passenger pigeons are not the only creatures that have been made extinct by the actions of people.

There are dozens of other examples, as well as some creatures whose existence is currently in serious peril, such as the golden lion tamarin and the thamin. Additional resources: Endangered Species Protection Program 
 U.S. Fish & Wildlife Service’s Endangered Species Program Endangered species Do some research on your own about an endangered species of your choice. It can be either a plant or an animal. Consider the biological, ethical, and economic aspects that have led to the endangerment as well as their role in protecting the species.

Then, during the week, be sure to address the following: · In a short paragraph (5-7 sentences) describe the species that you chose to learn more about and describe the basic reasons for its endangerment. · What characteristics make some species more vulnerable to extinction, while others seem to thrive despite changes in their surroundings? · How do the extinctions of other creatures affect humans directly and indirectly? · Why are decisions about recovery and preservation of these creatures so complicated? · What, if any, ethical responsibilities do we have to other creatures on the planet? · What sorts of trade-offs would you be willing to make in order to help protect an endangered species?

Would you make the same trade-offs for all types of species including plants, insects, amphibians, etc., in addition to those we tend to be more fond of, like whales, tigers, and koala bears? · Later in the week, compare your chosen organism to some described by your classmates. Do they share any common features? For example: Are they endangered for the same reasons? Do they share similar habitats or behaviors? Remember to read the Discussion requirements, found in the Unit 6 "Directions" Icon.

The extinction of the passenger pigeon, once abundant in North America, stands as a stark symbol of human impact on biodiversity. This species, once numbering in the billions, was driven to extinction primarily due to overhunting and habitat destruction during the 19th and early 20th centuries. The passenger pigeon’s collapse resulted from commercial hunting for meat and feathers, along with the extensive deforestation caused by expanding agriculture and urbanization. As a result, by the early 1900s, the passenger pigeon was declared extinct, highlighting one of the most rapid and devastating human-induced extinctions in recorded history.

Certain characteristics influence a species’ vulnerability to extinction. Species with low reproductive rates, specialized habitat requirements, or limited geographical ranges are more susceptible. For example, the Amur leopard’s low reproductive rate and fragmented habitat make it highly vulnerable, whereas adaptable species like raccoons thrive despite environmental changes. Generalist species that can exploit various habitats and food sources tend to survive better amid ecological disturbances, while specialists often struggle to adapt, leading to higher extinction risks.

The extinction of species affects humans both directly and indirectly. Direct effects include loss of resources such as food, medicine, and ecosystem services, while indirect effects encompass the destabilization of ecosystems, reduced biodiversity, and loss of cultural or aesthetic values. For instance, the decline of pollinators like bees threatens global food production, emphasizing the interconnectedness of human well-being and species survival.

Decisions regarding the recovery and preservation of endangered species are complex due to ecological, economic, and ethical considerations. Ecologically, the introduction of conservation measures must balance ecosystem health and species-specific needs. Economically, resources allocated to conservation could conflict with immediate human development needs. Ethically, humans grapple with responsibilities to preserve other species' rights to exist and thrive, raising questions about our moral obligations.

From an ethical standpoint, many argue that humans have a duty to protect other creatures, recognizing intrinsic value beyond utilitarian benefits. This ethical responsibility emphasizes stewardship and our role as caretakers rather than exploiters. Conversely, some contend that conservation efforts should be prioritized based on species' ecological roles or potential benefits to humans, which can justify trade-offs.

Trade-offs in conservation often involve sacrificing land for wildlife corridors or restricting economic activities like logging or mining. Personal willingness to make such sacrifices varies; I believe protecting biodiversity is crucial, even if it requires limitations on certain human pursuits. However, I would differentiate these trade-offs based on species’ ecological significance and conservation status. For highly charismatic species like tigers or koalas, greater effort might be justified, though I believe all species, including insects and plants, deserve protection due to their ecological roles and intrinsic worth.

Comparing my chosen species — the South Asian tamarind (Tamarindus indica), an endangered plant — with those of my classmates, reveals common themes. Many species share the same threats: habitat loss, overexploitation, and climate change. For example, both the tamarind and another endangered primate might share habitat overlap, such as forest ecosystems, and face similar pressures. These similarities underscore the importance of holistic conservation strategies that address root causes of endangerment, including habitat preservation and sustainable resource management.
