Study Notes
Deforestation and Its Causes
- Natural causes of deforestation include forest fires and severe droughts.
- Man-made causes include agricultural expansion, urbanization, logging, and infrastructure development.
- Cutting down trees disturbs the ecological balance and reduces biodiversity.
Consequences of Deforestation
- Increases atmospheric carbon dioxide levels, leading to global warming.
- Reduces groundwater levels and affects rainfall patterns.
- Disturbance in natural habitats leads to endangerment and extinction of various species.
Importance of National Parks and Wildlife Sanctuaries
- Serve to protect biodiversity and keep ecosystems intact.
- Enforce strict regulations against poaching, hunting, and habitat destruction.
- Function as safe havens for both large and small endangered species.
Endangered Species and Extinction
- Animals are categorized as endangered when their population decline poses extinction risks.
- Smaller animals, such as reptiles and amphibians, may be more threatened than large mammals.
- Extinction of species disrupts food chains and negatively affects ecosystem health.
Migratory Birds
- Migratory birds travel long distances to lay eggs and escape harsh climates.
- Their migration is driven by seasonal changes and habitat conditions.
Red Data Book
- An international record that documents endangered plant and animal species.
- India maintains its own Red Data Book to highlight local conservation needs.
Recycling and Paper Conservation
- One tonne of paper requires about 17 mature trees, emphasizing the need for paper conservation.
- Paper can be recycled 5 to 7 times, reducing tree cutting and manufacturing energy consumption.
- By saving paper, individuals contribute to forest conservation and minimize environmental impact.
Reforestation
- Reforestation is proposed as a solution to combat deforestation.
- Planting more trees ensures preservation of green wealth for future generations.
Individual Action and Conservation
- Personal efforts can contribute to maintaining local green wealth by implementing simple actions like recycling, conserving paper, and participating in local reforestation initiatives.
- Awareness of the consequences of deforestation empowers individuals to advocate for sustainable practices.
