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
It is the sum of all surroundings which we see.
Types of environments
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.
Further types of natural
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.
Human impact or influence on
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
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.
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
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.
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.
