  • 2. What is Nature ? Nature, in the broadest sense, is the nat ural, physical or material world or univ erse. "Nature" can refer to the phenomena of the physical world, and also to life in g eneral. The study of nature is a large part of s cience. Although humans are part of nature, human activity is often understo od as a separate category from other na tural phenomena.
  • 3. What is Global Warming? Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth .
  • 4. Effects of Global Warming 1. It's nearly impossible to overstate the threat of climate change. Greenhouse gas emissions are rising more rapidly than predicted and consequently the world is warming more quickly. 2. Global warming will have catastrophic effects such as accelerating sea level rise, droughts, floods, storms and heat waves. These will impact some of the world's poorest and most vulnerable people, disrupting food production, and threatening vitally important species, habitats and ecosystems. 3. Despite compelling scientific evidence, governments and businesses have responded very slowly. Even if countries fulfil all current mitigation pledges, the world will still face between 2.6 and 4 ºC of warming.
  • 5. Abuse of Nature Abuse of nature means how we abuse the nature by the activities like deforestation , global warming etc.
  • 6. Abuse of Nature Agricultural activities: As earlier mentioned in the overview, agricultural a ctivities are one of the major fact of deforestation. Logging: Apart from this, wood based industries like paper, match-sticks, furniture etc also need a substantial a mount of wood supply. Wood is used as fuel both directly and indirectly, therefore trees are chopped for supplies.
  • 7. Abuse of Nature Urbanization: Further on order to gain access to thes e forests, the construction of roads are undertaken; here again trees are chopp ed to create roads. Desertification of land: Some of the other factors that lead to deforestation are also part natural and part anthropogenic like Desertification of land. It occurs due to land abuse ma king it unfit for growth of trees
  • 8. Abuse of Nature Mining: Oil and coal mining require consider able amount of forest land. Apart fro m this, roads and highways have to be built to make way for trucks and other equipment. The waste that co mes out from mining pollutes the en vironment and effects the nearby spe cies and abuse making it unfit for gr owth of trees.
  • 9. Green House Effect The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by at mospheric greenhouse gas es, and is re-radiated in all directions.
  • 10. Sustainable development means development th at takes place without damaging the environmen t development that meets the needs of the pres ent without compromising the ability of future g enerations to meet their own needs. What is Sustainable Development
  • 11. What is pollution Pollution is the introduction of contaminant s into the natural environment that cause adv erse change. Pollution can take the form of c hemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/en ergies or naturally occurring contaminants . Five types of pollution :-
  • 12. Air Pollution Air pollution is the introducti on of particulates, biological mol ecules, or other harmful gases in to Earth's atmosphere, causing d isease, death to humans, damag e to other living organisms such as food crops, or the natural or built environment .
  • 13. Water Pollution Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). This form of environmental degradation occurs whe n pollutants are directly or indirectly dis charged into water bodies without ade quate treatment to remove harmful co mpounds.
  • 14. Noise Pollution Noise pollution is the disturbing a nd excessive noise that may harm the activity or balance of human o r animal life. The source of most o utdoor noise worldwide is mainly caused by machines and transport ation systems, motor vehicles , air craft and trains.
  • 15. Land Pollution Land pollution means degradation or d estruction of earth’s surface and soil, dir ectly or indirectly as a result of human activities. Anthropogenic activities are c onducted citing development, and the s ame affects the land drastically, we witn ess land pollution; by drastic we are ref erring to any activity that lessens the q uality and/or productivity of the land as an ideal place for agriculture, forestatio n, construction etc. The degradation of l and that could be used constructively in other words is land pollution.
  • 16. Light Pollution Light pollution is excessive, misdirected, or obtrusive artificial light. Pollution is the add ing-of itself, in analogy to added sound, ca rbon dioxide, etc. Adverse consequences ar e multiple; some of them may not be know n yet.
