Conservation of Plants and Animals

Conservation of Plants and Animals: Complete Guide for CBSE Class 8

Introduction to Conservation of Plants and Animals

Conservation of plants and animals is the systematic protection and management of Earth's biological diversity. Every year on 5th June, World Environment Day is celebrated globally to raise awareness about environmental protection and draw political attention to the urgent need for sustainable practices.

The conservation of biodiversity is not just about protecting individual species it's about maintaining the delicate ecological balance that sustains all life on Earth, including humans. From the oxygen we breathe to the food we eat, our survival is intrinsically linked to healthy ecosystems.

What is Biodiversity?

Biodiversity refers to the variety of life forms and habitats found in a particular area. According to the Convention on Biological Diversity (CBD) established at the 1992 Earth Summit:

"Biological diversity means the variability among living organisms from all sources including terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems."

Three Levels of Biodiversity

Level Description Examples
Ecosystem Diversity Variety of ecological complexes or biotic communities in an area Tropical rainforests, grasslands, wetlands, coral reefs
Species Diversity Variety of different species in a region Number of plant, animal, and microorganism species per unit area
Genetic Diversity Variations in genetic material within species Different varieties of rice, wheat; variations in human populations

Biodiversity Gradients

  • Latitude gradient: Biodiversity increases from poles to equator
  • Altitude gradient: Species diversity decreases from lower to higher altitudes on mountains
  • Environmental conditions: Areas with favorable climate (like tropical rainforests) have maximum biodiversity
  • Seasonal variations: High seasonal variations lead to reduced biodiversity

Importance of Forests and Biodiversity

Forests are invaluable natural resources that form the backbone of terrestrial ecosystems. Their significance extends across ecological, economic, and social dimensions.

Ecological Significance

  1. Ecosystem Balance: Forests maintain ecological equilibrium by regulating biogeochemical cycles
  2. Habitat Provision: Home to countless plant and animal species
  3. Climate Regulation: Maintain atmospheric CO₂ and O₂ concentrations
  4. Soil Conservation: Prevent soil erosion and landslides through root systems
  5. Soil Enrichment: Decomposed plant matter forms humus, enriching soil fertility
  6. Water Cycle Maintenance: Regulate rainfall patterns through transpiration
  7. Fossil Fuel Formation: Contribute to long-term carbon sequestration

Economic and Social Importance

  • Forest Products: Timber, gum, paper, medicines, resins
  • Livelihood Support: Many tribal communities depend entirely on forests for survival
  • Aesthetic Value: Many plants like Peepal and Tulsi are considered sacred
  • Scientific Research: Source of genetic material for breeding programs in agriculture and animal husbandry

Uses of Biodiversity

Ecosystem Services: All organisms in an ecosystem are interconnected; destruction of one species can upset the entire ecological balance.

Commercial Importance:

  • Marine and freshwater fish provide substantial food resources
  • Wildlife products: fur, skin, musk, ivory
  • Plant products: timber, gums, resins, medicines

Medicinal Value:

  • Morphine from Papaver somniferum (analgesic)
  • Quinine from Cinchona (anti-malarial)
  • Countless traditional medicines derived from plants

Economic Contributions:

  • Plants as primary producers in ecosystems
  • Oxygen production through photosynthesis
  • Pollination services by animals
  • Decomposition by microorganisms
  • Nitrogen fixation by certain microbes

Silviculture: Science of Forest Management

Silviculture is the branch of science dealing with the management and development of forest trees. Silvics involves understanding how trees grow, reproduce, and respond to environmental changes.

Silvicultural Harvesting Methods

  1. Selection Systems: Partial removal of trees based on silvicultural objectives
    • Used when shade-tolerant or intermediate-tolerance species are desired
    • Each tree is individually assessed, measured, and marked for cutting or retention
  2. Seed Tree Cuts: Harvest all trees except 2-10 trees per acre
    • Remaining trees chosen for good form, genetics, and seed production capacity
    • These "parent trees" disperse genetically superior seeds over disturbed areas
  3. Clearcutting: Complete removal of all trees in an area
    • Used when sun-loving species are desired for future timber stands
    • Prescribed in poor-quality or fire-damaged stands
    • In pine management, immediately followed by seedling plantation

Deforestation: A Major Threat to Biodiversity

Deforestation is the loss or continual degradation of forest habitat due to natural causes or human intervention.

Causes of Deforestation

  1. Agricultural Expansion: Conversion of forests to cropland
  2. Dam Construction: Submergence of forest areas for hydroelectric projects
  3. Grazing and Overgrazing: Farmland requirements for livestock
  4. Urbanization: Expansion of cities and towns
  5. Commercial Logging: Timber extraction for industry
  6. Forest Fires: Both natural and human-induced
  7. Developmental Projects: Infrastructure development

Effects of Deforestation on Environment

1. Impact on Carbon Cycle

  • Forests act as major carbon stores, absorbing CO₂ for photosynthesis
  • When forests are cleared and trees burnt or decomposed, stored carbon is released as CO₂
  • Estimated contribution: Deforestation accounts for one-third of all human-caused CO₂ emissions
  • Increases atmospheric CO₂ concentration, contributing to greenhouse effect and global warming

2. Disruption of Water Cycle

  • Trees draw groundwater through roots and release it through transpiration
  • In regions like Amazonia, over half the water circulates within plant systems
  • Forest removal reduces regional water retention capacity
  • Result: Drier climate and reduced rainfall

3. Soil Erosion

  • Tree roots bind soil particles together
  • Removal of protective vegetation exposes loose soil
  • Wind and water erosion remove topsoil rich in humus and nutrients
  • Consequence: Reduced soil fertility and agricultural productivity

4. Changes in Material Recycling

  • Plants absorb CO₂ and release O₂ during photosynthesis
  • Deforestation reduces O₂ levels in the atmosphere
  • Increased CO₂ concentration leads to greenhouse effect
  • Reduced transpiration disrupts local rainfall patterns

5. Climatic Changes

  • Increased CO₂ traps solar infrared radiation (greenhouse effect)
  • Rising temperatures create drier atmospheric conditions
  • Result: Reduced rainfall and potential droughts

6. Landslides and Floods

  • Vegetation absorbs rainwater naturally
  • Without forest cover, greater rainwater reaches ground directly
  • Loss of binding capacity of soil during rainy season
  • Impact: Increased flood risk and landslides in mountainous regions

7. Desertification

  • Soil erosion removes top fertile layer
  • Physical properties of soil deteriorate without vegetation
  • Gradual transformation: Fertile land converts to desert

8. Species Extinction

  • Forests contain more than half of all Earth's species
  • Habitat destruction leads to species decline
  • Estimated loss: Tropical forests lose 14,000-40,000 species per year
  • Projection: Nearly 50% of species may become extinct by end of 21st century

9. Impact on Wildlife

  • Forests are natural habitats for numerous species
  • Cutting trees destroys homes of these species
  • Result: Endangerment and extinction of dependent species

Threats to Biodiversity

Recycling of Paper: A Conservation Practice

Paper production requires cellulose fiber, primarily sourced from wood pulp. Recycling paper is one of the easiest and most effective conservation practices.

Paper Recycling Process:

  1. Collection and Sorting
    • Remove contaminants (plastics)
    • Sort by paper type (each creates different recycled paper)
  2. Pulping
    • Sorted paper passed through pulper with warm water and chemicals
    • Breaks paper into tiny cellulose strands (fibers)
    • Gradually converts to pulp
  3. Filtering and Cleaning
    • Pulp filtered through sieves to remove impurities
    • Spinning in cone-shaped cylinders removes contaminants
    • Heavy contaminants thrown outward; lighter ones collect at center
  4. De-inking
    • Pulp undergoes de-inking in flotation chamber
    • Removes printing ink from paper
  5. Bleaching
    • De-inked pulp bleached to produce white paper
  6. Sheet Formation
    • Pulp mixed with virgin fiber (if needed) for strength and smoothness
    • Water drained through wire screen
    • Fibers form sheet
    • Passed through press rollers to squeeze out more water
    • Final paper wound into rolls

Environmental Benefits:

  • Reduces tree harvesting
  • Saves energy and water
  • Reduces landfill waste
  • Lowers greenhouse gas emissions

Role of Communities in Conservation Efforts

Community participation is vital for successful conservation:

  1. Traditional Knowledge: Indigenous communities possess valuable ecological knowledge
  2. Local Stewardship: Communities living near forests can monitor and protect resources
  3. Sustainable Practices: Traditional sustainable use practices can be integrated
  4. Economic Incentives: Eco-tourism and sustainable products provide livelihoods
  5. Awareness Generation: Local communities spread conservation messages effectively
  6. Conflict Resolution: Mediating human-wildlife conflicts

Key Terms and Definitions

Ecosystem Balance

The state of dynamic equilibrium within an ecosystem where species populations, nutrient cycles, and energy flows remain stable over time.

Poaching and Illegal Wildlife Trade

Illegal hunting or capturing of wild animals, often driven by demand for animal parts (ivory, horns, fur) in black markets.

Forest Degradation

Decline in forest quality through selective logging, overgrazing, or pollution without complete forest clearing.

Species Extinction

Complete elimination of a species from Earth, representing irreversible loss of genetic diversity.

Habitat Fragmentation

Division of large continuous habitats into smaller, isolated patches, reducing species movement and genetic exchange.

Ecological Restoration

Process of assisting recovery of damaged, degraded, or destroyed ecosystems.

Sustainable Development

Development that meets present needs without compromising the ability of future generations to meet their needs.

Environmental Awareness

Understanding of environmental issues and their impact, leading to responsible actions toward conservation.

Conclusion

The conservation of plants and animals is not just an environmental issue—it's fundamental to human survival and well-being. Every species plays a unique role in maintaining the ecological balance that sustains life on Earth. From the oxygen we breathe to the food we eat, from medicines to climate regulation, we depend entirely on healthy, functioning ecosystems.

The threats are real and urgent: deforestation, habitat loss, climate change, pollution, and overexploitation are driving species to extinction at unprecedented rates. However, hope remains. Through coordinated efforts involving governments, communities, scientists, and individuals, we can protect and restore biodiversity.

Conservation requires understanding both the science (ecology, biodiversity patterns, ecosystem functions) and the action (protected areas, sustainable practices, community participation, legal frameworks). The Chipko Movement and various successful conservation projects demonstrate that when communities, governments, and conservationists work together, remarkable outcomes are possible.

As future stewards of our planet, students must understand these concepts deeply and commit to making informed, responsible choices. Every action counts—from planting a tree to avoiding products from endangered species, from reducing waste to spreading awareness.

Remember: "Ecology is permanent economy." The health of our planet determines the future of humanity. Let's ensure that future generations inherit a world as diverse, beautiful, and abundant as the one we have received.
