Deforestation

-
The unwise and unplanned destruction or removal of trees is called deforestation.  Forests are our most precious wealth. Our life is greatly dependent on forests. They are the natural factories for the production of oxygen. Forests provide green cover to the earth , a living place to wildlife,  fuel,  timber and recreation to man.  They control floods,  prevent formation of deserts and keep the air clean. Some of the reasons for deforestation are given below:
a.   Urbanisation requires more land , thus forests are cut to build roads and houses etc.
b.   More land is required for cultivation.
c.    Trees are removed to develop pastures for grazing.
d.    Wood is used both as timber or fuel wood.
e.   Some plants are collected for their medicinal importance.
f.   Some plants are removed to give us fibre.
g.   Timber mafia cut the trees for easy cash.


  Deforestation in tropical rainforests impact global environment. 

Effect on Environment
Deforestation has many negative effects on the environment. The most dramatic impact is Loss of habitat for millions of species. Seventy percent of Earth's land animals and plants live in forests,  and many cannot survive the deforestation that destroys their homes.
Deforestation also affects Climate change.  Forest soils are moist,  but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapour back into the atmosphere.  Without trees to fill these roles,  many former forest lands can quickly became barren deserts.
Trees also play a critical role in absorbing the greenhouse gases that is responsible for global warming.

Components of Ecosystem

An ecosystem consist of two major components namely , abiotic components and biotic components. Both these components are equally important for the proper functioning of the ecosystem. a. Abiotic components of Ecosystem The following are the major abiotic components of an ecosystem 1.Light    2. Water   3. Temperature  4. Atmosphere   5. Fire    6. Soil   7. Inorganic material    8. Gravity 1. light Light influences the growth and distribution of living organisms. Plants utilize sunlight during photosynthesis and prepare food. Light intensity, light quality,  light quantity and light duration affect life of animals and plants in one way or the other. For example the plant growing under insufficient light do not develop chlorophyll and they high intensity of light destroys chlorophyll.      Rainforests are home to rich biodiversity present on  2.water  Water is a vital component of life.

The facts about the creation and the hollowness of the theory of Evolution

There is a wide spread unscientific theory in the western world that the organisms of today have evolved from previous ancestors . The theory was proposed by darwin and readily accepted by the west. They theory of evolution states the first unicellular organisms evolved by chance factors.  From unicellular organsms multicellular organsims evolved. And similarly during the course of evolution human beings have evolved from monkey.  And theory in science proposed should be supported by proofs and evidence.  If sufficient evidence based on experiments prove that theory is correct , then it is accepted as a scientific fact.      Western scientists have tried their level best searching and applying all possibilities to make a living cell, but they have failed to do so. With all the sophisticated instruments and modern technology and all possible efforts if the western scientists think tank cannot make a single living cell , then how one can believe that all the...

Drug Addiction and Associated problems

Apart from the nagative physical effects of drug use there are psychological and emotional effects that are equally as devastating. One of the areas that is almost universally damaged is a person's view of oneself,  their self-esteem. Self-esteem virtually never rises when drug use is induced;  it almost always sinks lower and lower. As a person's self-esteem decreases through drug use,  the nagative feeling of worthlessness,  hopelessness , shame and guilt increase.   Drug addicts : a menace for society This is often due to the fact that a person realizes deep down that drug use is a destructive thing to be doing,  yet they do it anyway.  This sets up a contradiction between internal values and actual actions taken. One of the most destructive things that drug use does is it interferes with a person's ability to from caring and honest: relationships. It also tends to destroy relationships that currently exits.  This is essentially due to th...
