Factors affecting environment

Environmental issues are the harmful effects of human activities on the environment. These include pollution, over-population, waste disposal, climate change, global warming, greenhouse effect, etc.

$\bigstar \underbrace{ \bold{Climate \: Change}}$

• Climate change is a great concern in today’s scenario. This problem has surfaced in the last few decades. Greenhouse gases are the major cause of climate change. Environmental changes have several destructive impacts such as the melting of glaciers, change in seasons, epidemics, etc.

$\bigstar \underbrace{ \bold{Global \: Warming}}$

• The burning of fossil fuels, emissions from the automobiles and chlorofluorocarbons add to the greenhouse gases in the atmosphere. This has led to an increase in earth’s temperature causing environmental changes. This increase in temperature across the globe is known as global warming.

$\bigstar \underbrace{ \bold{Ozone \: Layer \: Depletion}}$

• The ozone layer is a layer of concentrated ozone gas. It protects us from the sun’s harmful ultraviolet rays. This very important layer is being destroyed by CFCs (chlorofluorocarbons), which are used in industries and everyday life (e.g. aerosol cans).

$\bigstar \underbrace{ \bold{Water \: Pollution}}$

• The introduction of harmful substances into rivers, oceans, lakes and ponds, which changes the physical, chemical or biological condition of the water is called water pollution.

$\bigstar \underbrace{ \bold{Air \: Pollution}}$

• Air pollution is the result of emissions from the industries, automobiles, and increasing use of fossil fuels. The gaseous emissions have added to an increase in the temperature of the earth.

$\bigstar \underbrace{ \bold{Deforestation}}$

• Deforestation is the depletion of trees and forests at an alarming rate. The trees provide us with oxygen, several raw materials and also maintain the temperature of the earth.

$\bigstar \underbrace{ \bold{Over \: population}}$

• The earth’s population is increasing drastically. It is estimated to be more than seven billion. The increasing population has led to a shortage of resources. If this continues, it will be very difficult to sustain such a huge population.

$\underbrace{\overbrace{ \bold{Solutions \: to \: Environmental \: Issues}}}$

• Replace disposal items with reusable items.
• The use of paper should be avoided.
• Conserve water and electricity.
• Support environmental friendly practices.
• Recycle the waste to conserve natural resources.

$\bigstar\overbrace{\underbrace{ \bold{ENVIRONMENT}}}$

• The word environment is derived from the french word environ, which means to surround, Thus the environment refers to the Sum total of the conditions of the surroundings within which an organism exists.

$\bigstar\overbrace{\underbrace{ \bold{Components \: of \: the \: ENVIRONMENT}}}$

• The components of environment are the natural environment and human environment.

• The natural environment can be subdivided into the aboitic environment and biotic environment.

• The human environment consists of the elements that devoloped as a result of interaction between human beings and nature.

$\bigstar\overbrace{\underbrace{ \bold{THE \: NATURAL \: ENVIRONMENT}}}$

The natural environment consists of living and non living things that occur naturally on earth.

$\pink \bigstar \underbrace{ \pink{ \bold{The \: Aboitic \: Environment}}}$

The Aboitic Environment consists of inorganic or non living things of the environment they can be divided into Lithosphere, hydrosphere, Atmosphere.

$\pink{Lithosphere:}$

• Lithosphere is the outer most solid layer of the earth's crust.

• It comprises of minerals,soil,rocks moulded into various land forms.

• The Lithosphere provides habitat for plants, animals including humans.

$\blue{Hydrosphere:}$

• The realm of the earth consisting of water, including ground water is called hydrosphere.

• The sources of water include oceans,seas, rivers,lakes, ground water,ice caps and glaciers. about 71% of the earth's surface is composed of water.

• It is very important source for survival of all forms on the earth.

$\green{Atmosphere:}$

• The mixture of gases that envelopes the Earth is called atmosphere.

• The earth's gravitational pull holds the gases of Atmosphere.

• It also protect the earth from ultraviolet rays from the sun.

$\pink \bigstar \underbrace{ \pink{ \bold{The \: boitic \: Environment}}}$

The Lithosphere, hydrosphere,Atmosphere meet to form a narrow zone of interaction which supports life is known as Biosphere.

• It comprises biotic as well as Aboitic Environment.

• The Bioshere has made earth unique planet in the solar System by providing favorable conditions.

• The biosphere consists of all distinct regions called biomes and aquatic life zones

THE HUMAN ENVIRONMENT

• The human environment is concerned with people.
