1.5 Development of conservation movements

Conservation movements emerged as a response to rapid industrialization and resource depletion in the 19th century. Early efforts focused on preserving landscapes, managing wildlife, and promoting sustainable resource use in fishing and forestry.

Key figures like John Muir and Gifford Pinchot shaped conservation philosophies, while events like the Dust Bowl highlighted environmental concerns. These movements led to protected area designations and influenced modern approaches to natural resource management.

1 of 3

• Deforestation accelerated in the 19th century led to soil erosion and habitat loss
• Overhunting of wildlife species threatened populations (passenger pigeon, bison)
• Water pollution from industrial waste impacted aquatic ecosystems and fish populations
• Soil degradation from intensive agriculture reduced land productivity

Influential conservationists

• John Muir advocated for wilderness preservation founded the Sierra Club in 1892
• Gifford Pinchot promoted scientific forestry and sustainable resource management
• Rachel Carson's "Silent Spring" (1962) raised awareness about pesticide impacts on ecosystems
• Aldo Leopold developed the land ethic philosophy emphasizing ecological interconnectedness

Key historical events

• Establishment of Yellowstone National Park in 1872 marked the beginning of protected area designations
• Dust Bowl of the 1930s highlighted the need for soil conservation practices
• First Earth Day celebration in 1970 galvanized public support for environmental protection
• Stockholm Conference in 1972 put global environmental issues on the international agenda

Conservation philosophies

• Conservation philosophies guide approaches to natural resource management and environmental protection in fishing and wildlife sectors
• These philosophies influence policy decisions, management strategies, and public attitudes towards nature conservation

Preservation vs conservation

• Preservation advocates for minimal human intervention in natural areas
• Conservation promotes sustainable use and management of natural resources
• Preservation focuses on intrinsic value of nature (wilderness areas, national parks)
• Conservation balances human needs with environmental protection (managed forests, fisheries)

Sustainable use principles

• Harvest rates should not exceed regeneration rates of renewable resources
• Ecosystem carrying capacity guides resource extraction limits
• Long-term viability of populations prioritized over short-term economic gains
• Adaptive management adjusts practices based on monitoring and scientific data

Ecosystem-based management

• Holistic approach considers entire ecosystems rather than single species
• Recognizes interconnections between terrestrial, freshwater, and marine environments
• Incorporates human activities as part of the ecosystem
• Aims to maintain ecosystem structure, function, and resilience

Major conservation movements

• Conservation movements address specific environmental concerns and ecosystems, often focusing on particular species or habitats
• These movements have shaped public perception and policy regarding natural resource management in fishing and wildlife sectors

Wildlife conservation

• Focuses on protecting endangered species and maintaining biodiversity
• Establishes protected areas and wildlife corridors to preserve habitats
• Implements captive breeding programs for critically endangered species
• Addresses issues of poaching and illegal wildlife trade through law enforcement and education

Marine conservation

• Aims to protect ocean ecosystems and marine biodiversity
• Establishes marine protected areas and no-take zones to allow fish populations to recover
• Addresses issues of overfishing through catch limits and gear restrictions
• Combats marine pollution (plastic waste, oil spills) through regulations and cleanup efforts

Forest conservation

• Promotes sustainable forestry practices and protection of old-growth forests
• Implements reforestation and afforestation programs to restore degraded lands
• Addresses deforestation drivers (agriculture expansion, logging) through policy and alternative livelihoods
• Recognizes forests' role in climate regulation and biodiversity conservation

Legislative milestones

• Conservation legislation provides legal frameworks for environmental protection and natural resource management
• These laws have significantly impacted fishing and wildlife conservation practices in the United States

National park system

• Established by the National Park Service Organic Act of 1916
• Protects diverse landscapes and ecosystems for public enjoyment and conservation
• Balances preservation with recreational access and educational opportunities
• Serves as a model for protected area systems worldwide

Endangered Species Act

• Enacted in 1973 to protect threatened and endangered species and their habitats
• Requires federal agencies to ensure their actions do not jeopardize listed species
• Prohibits "taking" of listed species includes harming, harassing, or killing
• Mandates development of recovery plans for listed species

Clean Water Act

• Passed in 1972 to regulate water pollution and protect water quality
• Establishes water quality standards and regulates point source pollution discharges
• Requires permits for wetland alterations (Section 404)
• Impacts fishing industry by improving aquatic habitats and fish populations

International conservation efforts

• Global conservation initiatives address transboundary environmental issues and promote cooperation among nations
• These efforts influence fishing and wildlife management practices on an international scale

Global agreements

• Convention on Biological Diversity (1992) promotes conservation and sustainable use of biodiversity
• Convention on International Trade in Endangered Species (CITES) regulates wildlife trade
• Ramsar Convention protects wetlands of international importance
• United Nations Convention on the Law of the Sea governs marine resource management

Transboundary conservation

• Peace parks establish protected areas across national borders (Great Limpopo Transfrontier Park)
• Migratory species conservation requires international cooperation (Monarch butterfly, sea turtles)
