Frequently Asked Questions (FAQ) – Environmental Science
1. What is Environmental Science?
Environmental Science is the study of the environment, its components, their interactions, environmental problems, and methods of environmental protection and conservation.
2. What are the major components of the environment?
The major components include biotic components such as plants, animals and microorganisms, and abiotic components such as air, water, soil, sunlight and temperature.
3. What are the major spheres of Earth?
The major spheres are lithosphere, hydrosphere, atmosphere and biosphere.
4. What are natural resources?
Natural resources are materials and substances obtained from nature that are useful to humans and other organisms, such as water, forests, soil, minerals and energy resources.
5. What is an ecosystem?
An ecosystem is a functional unit of nature in which living organisms interact with one another and with non-living components of their environment.
6. What are the main components of an ecosystem?
An ecosystem consists of abiotic components and biotic components. Biotic components include producers, consumers and decomposers.
7. What is biodiversity?
Biodiversity refers to the variety and variability of living organisms, including genetic diversity, species diversity and ecosystem diversity.
8. What are biodiversity hotspots?
Biodiversity hotspots are regions with exceptionally high levels of endemic species that have also experienced extensive loss of their original natural vegetation.
9. What are the major threats to biodiversity?
Major threats include habitat loss, habitat fragmentation, overexploitation, invasive species, pollution, climate change, poaching and illegal wildlife trade.
10. What is environmental pollution?
Environmental pollution is an undesirable change in the physical, chemical or biological characteristics of the environment that can cause harmful effects.
11. What are the major types of environmental pollution?
The major types include air pollution, water pollution, soil pollution, marine pollution, noise pollution, thermal pollution and light pollution.
12. What is solid waste management?
Solid Waste Management is the systematic process of waste reduction, segregation, collection, transportation, recycling, treatment, recovery and safe disposal of solid waste.
13. What is composting?
Composting is the controlled biological decomposition of biodegradable organic waste into a stable, humus-like material called compost.
14. What is rainwater harvesting?
Rainwater harvesting is the collection and storage of rainwater for suitable uses or for groundwater recharge.
15. What is climate change?
Climate change refers to long-term changes in temperature and other characteristics of the Earth's climate. Modern climate change is strongly influenced by human activities that increase greenhouse gas concentrations.
16. What is global warming?
Global warming refers specifically to the long-term increase in Earth's average surface temperature, primarily due to the enhanced greenhouse effect.
17. What is the Environment (Protection) Act, 1986?
The Environment (Protection) Act, 1986 is an important Indian environmental law that provides a broad legal framework for protecting and improving the environment and controlling pollution.
18. What is disaster management?
Disaster management is the organized process of reducing disaster risk and preparing for, responding to and recovering from disasters.
19. What are the major stages of disaster management?
The major stages are mitigation, preparedness, response and recovery.
20. How can individuals help protect the environment?
Individuals can conserve water and energy, reduce waste, reuse and recycle materials, avoid littering, reduce unnecessary plastic use, protect biodiversity, plant and protect trees, and follow environmental regulations.
