NATURAL ENVIRONMENT

  1. 1. NATURAL ENVIRONMENT Name- Abhra Pawan Sharma Class- 9H Roll no- 4
  2. 2. ENVIRONMENT  Everything around us is known as environment.  It includes every living and non living thing.  Everything which we see in our surroundings such as sunlight, atmosphere, land, water, minerals, humans, plants, animals, insects, air etc. comes in environment.  It is the sum of all surroundings which we see.
  3. 3. Types of environments  Natural environment  Human environment  Physical environment
  4. 4. NATURAL ENVIRONMENT  The natural environment means the non human made surroundings conditions in which all biotic and abiotic things exists on earth. Natural environment can further be divided into 4 parts.
  5. 5. Further types of natural environment  Lithosphere- It is defined as the rock and crust surface that covers the earth. An example of lithosphere is the rocky mountain range.  Hydrosphere- all the water on the earths surface such as lakes and seas is known as hydrosphere.  Atmosphere- the mixture of gases that surrounds the earth is known as atmosphere.  Biosphere- the part of earths surface and atmosphere which supports life and where plants and animals live is known as biosphere.
  6. 6. Human impact or influence on environment. we are living in this environment so we have definitely gave an impact on environment. So lets see some positive and negative impact of humans on environment
  7. 7. NEGATIVE IMPACT  Humans are continuously cutting down trees and littering have a negative impact on environment  Pollution is everywhere, from the trash thrown out on the free way to the millions of metric tons of pollution pumped into the atmosphere every year.  Burning fossil fuels is the prime culprit from the climate for climate change. When oil gas and coal are burned they release carbon dioxide and other harmful gases which trap heat in atmosphere and cause it to warm up.  The increasing use of fertilizers and pesticides to protect crops have damaged the fertility of land.  Food wastage is a huge issue with an estimated one third of all food produced globally is being wasted.
  8. 8. POSITIVE IMPACT  Promoting afforestation plays an important role in reducing air pollution by improving overall air quality.  Conserving water resources- By not throwing industrial wastes, domestic wastes into rivers, lakes etc. water pollution can be prevented. Technique like rain water harvesting, watershed management, drip irrigation helps in conservation of water resources.  Soil conservation- methods like terrace farming, crop rotation, windbreaks play an important role in preventing soil erosion.  Conservation of flora and fauna by setting up conservation areas, botanical gardens, national parks and wildlife sanctuaries.  Use of renewable sources of energy like solar energy, biofuels, wind energy etc.
  9. 9. CONCLUSION  Since the dawn of time, human beings have solemnly dependent on mother nature to fulfil their needs from inhaling air to sustenance to food requirements. But we are unable to handle the greatness of nature, we have overused, exploited, wasted natural resources which will effect badly on future generations. So its our duty to utilize the resources carefully. If we do not then that day is not so far where there will be no water no food no oxygen and the life will be impossible.
