Question
The federal government has tried to protect the nation’s biodiversity in a number of ways. One of those ways is the Endangered Species Act, passed by the U.S. Congress in 1973. The act has two main purposes: (1) to list plant and animal species that are endangered or threatened (likely to be endangered in the foreseeable future), and (2) to protect the habitat in which these species live, with the goal of helping them recover.
The Endangered Species Act has always been the subject of much controversy. Some people feel that humans have to give up too much to protect plant and animal species that are not important. Others argue that humans should do everything they can to maintain biodiversity in the world, including protecting endangered and threatened species.
Prepare Controversies over endangered species almost always involve a specific species: bison, grizzly bear, the masked bobwhite, or Arizona agave, for example. Good arguments can be made for and against protecting the species.
In this activity, choose one of the plant or animal species listed in the table below to study in detail. Decide whether you want to argue for or against a program for protecting the species you have selected.
Research Make a list of arguments to support your position. Use your textbook or other library resources to find background information. Consider the role of the species in maintaining biodiversity in its ecological niche. Mention the species’ role as prey or predator in the food web and how its absence would alter the balance of nature in the area in which it lives.
Write Prepare a one- or two-page statement that summarizes your position about protecting the endangered species.

grizzly bear (Ursus arctos horribilis)

Position: Protect the grizzly bear (Ursus arctos horribilis)
Summary statement
I support a robust program to protect and recover grizzly bears. Grizzlies are a keystone apex omnivore whose presence sustains ecosystem function, biodiversity, and many indirect economic and cultural benefits. Because remaining grizzly populations in the contiguous United States are small, fragmented, and vulnerable to human-caused mortality and habitat loss, continued federal protection—combined with local, science-based management and cooperative mitigation programs—is necessary to secure both the bears’ long-term survival and reasonable human use of the landscape.
Background
Grizzly bears once occupied a broad range across western North America but are now largely restricted to Alaska and a few isolated recovery areas in the lower 48 (e.g., Yellowstone and portions of the northern Rocky Mountains). Small population size, habitat fragmentation, human-bear conflicts, and reduced connectivity increase extinction risk. The Endangered Species Act is designed to prevent that outcome and to facilitate recovery of populations to levels that are self-sustaining across their native range.
Arguments for protection
1. Ecological and biodiversity value
- Keystone and top-down effects: As large omnivores and top predators, grizzlies influence prey populations (ungulates, rodents) and the behavior and distribution of those species. These top-down effects can cascade through ecosystems, influencing vegetation structure, nutrient cycling, and the abundance of other animals.
- Nutrient transport and ecosystem engineering: Grizzlies move nutrients across the landscape by consuming berries, roots, and animals (including fish where available) and depositing them via scat. In salmon-bearing systems, bears transfer marine-derived nutrients inland. Their digging for roots and ground squirrels aerates soil and affects plant community composition.
- Biodiversity maintenance: By shaping habitats and food webs, grizzlies help maintain species diversity and ecosystem resilience. Loss of a large native carnivore can lead to overabundant prey herbivores, vegetation decline, increased disease prevalence, and simplified ecosystems.
2. Genetic and long-term viability
- Small, isolated populations are more susceptible to inbreeding, stochastic events, and local extirpation. Protected status helps prioritize habitat connectivity, corridors, and population augmentation where necessary to maintain genetic diversity and adaptive potential.
3. Economic and social benefits
- Ecotourism and recreation: Many landowners and local economies benefit from wildlife viewing and tourism associated with intact native large mammals and healthy ecosystems (visitors to Yellowstone and other recovery areas are drawn in part by the presence of iconic species).
- Ecosystem services: Healthy ecosystems provide services (water regulation, pollination support via intact food webs, soil health) that have long-term economic value.
4. Ethical, cultural, and legal obligations
- Many Americans and Indigenous peoples place intrinsic and cultural value on native wildlife. Federal protection under the ESA reflects a national commitment to conserve biological heritage and uphold legal responsibilities to prevent extinction.
Addressing common arguments against protection
Argument: Grizzlies threaten human safety and livestock, imposing unacceptable costs.
Response:
- Human fatalities due to grizzlies are extremely rare when appropriate prevention measures are used. Most conflicts stem from attractants (garbage, livestock carcasses, unsecured food).
- Cost-effective mitigation exists: livestock carcass removal, range riders, guard animals, electrified fencing, bear-resistant containers, and community education reduce conflicts. Compensation programs for verified livestock losses can reduce economic burdens on ranchers and improve local support for conservation.
- Management can include targeted non-lethal removal of problem bears and, where scientifically justified and legally allowed, regulated population management in specific zones—without removing federal protections that ensure recovery objectives and safeguards for connectivity.
Argument: The cost of recovery programs and restrictions on development are too high.
Response:
- Recovery costs are modest relative to long-term benefits of ecosystem services and tourism, and federal programs increasingly emphasize collaborative, incentive-based approaches that work with landowners to reduce conflict and conserve habitat without unnecessarily restricting responsible land use.
- Smart land-use planning and conservation easements can concentrate development where impacts to grizzly habitat are minimized, allowing coexistence.
Argument: Populations in some areas have recovered enough to remove ESA protections.
Response:
- Recovery should be measured at the appropriate spatial scale and include demographic stability, secure habitat, and connectivity to other populations. Premature delisting without addressing connectivity and long-term human-caused mortality risks can lead to backsliding.
- Federal protection can be adapted (through species-specific recovery plans and state-federal coordination) as populations sustainably increase, while ensuring safeguards for genetic health and range expansion.
Recommended approach
- Maintain federal protection for grizzly populations that are still vulnerable, while implementing adaptive, science-based recovery plans that emphasize:
- Habitat protection and restoration, and establishment of corridors to connect isolated populations.
- Funding and incentives for coexistence measures (livestock protection, waste management, community education).
- Compensation and support programs for affected landowners.
- Monitoring and research on population dynamics, genetics, and human-bear interactions to guide management.
- Collaborative governance involving federal and state agencies, tribes, private landowners, and local communities.
Conclusion
Protecting grizzly bears is not simply about preserving one species; it is about maintaining functional ecosystems, supporting biodiversity, honoring cultural and ethical commitments, and sustaining economic benefits tied to healthy natural landscapes. With targeted, cooperative management and reasonable mitigation measures, humans and grizzlies can coexist. Continued protection under a strong, adaptive recovery program is the best path to ensure grizzlies remain a living part of North America’s natural heritage.
