Study Notes
Eco Mark and Environmental Issues
- Eco Mark of the country features an earthen pitcher, symbolizing environmental consciousness.
- Melting of ice sheets primarily results from global warming, affecting climate and sea levels.
- Two acids formed from gases reacting with cloud droplets are sulphuric acid and nitric acid, contributing to acid rain.
- Acid rain is characterized as corrosive, damaging ecosystems and infrastructure.
Greenhouse Effect and Ozone Layer
- Full form of CFCs is chlorofluorocarbons, which are harmful to the ozone layer.
- Thinning of the ozone layer was first discovered in the atmosphere above Antarctica.
- The Montreal Protocol, signed in 1987, aims for the protection of the ozone layer.
- Greenhouse effect describes the phenomenon where radiation absorbed by the atmosphere is re-radiated towards Earth's surface.
Environmental Consequences
- Deforestation contributes to the greenhouse effect, reducing oxygen and increasing atmospheric carbon dioxide.
- Ethane is not classified as a greenhouse gas, while water vapor, carbon dioxide, and methane are significant contributors.
- Important heat-trapping gas primarily includes methane, vital for understanding climate change impacts.
Biodiversity and Ecology
- New species entering a region are referred to as exotic species or alien species.
- The Red Data Book catalogs threatened species, essential for conservation efforts.
- Ecology, a term introduced by Haeckel, pertains to interactions between organisms and their environment.
Environmental Education and Awareness
- Environmental studies encompass various disciplines, including psychology, demography, and ethics, but not literature.
- Items like food cannot be recycled, highlighting the importance of waste management practices.
- The concept of reducing, reusing, recycling, and recovery is known as the 4Rs for sustainable development.
Impact of Human Activities
- Anthropogenic environments are modified by human actions, contrasting with natural environments.
- Addition of limestone to soil effectively reduces the effects of acid rain.
- Global warming significantly alters natural atmospheric systems, weather patterns, and biodiversity.
Historical Context
- The term "environment" derives from the French word "environ," meaning to encircle or surround.
- The World Summit on Sustainable Development took place in Rio de Janeiro in 1992, addressing global environmental issues.
- M.S. Swaminathan is recognized as the father of the Green Revolution in India, revolutionizing agricultural practices.
