What is Body Mass Index or BMI ???

BMI is Mostly known as Body Mass Index.It is important for knowing our health conditions.Now I will show what is BMI??? & a chart for BMI. See it. It may be helpful to you.

Body Mass Index

What is BMI???
Answer: BMI is the ratio of "Body Weight in Kilogram" & (Height in Meter)².
BMI= Body Weight in Kilogram/(Height in Meter)².

Value of BMI with Health Conditions

BMI < 16 …………………………… Grade 3 Thickness.
16-16.99 …………………………… Grade 2 Thickness.
17-18.49 …………………………… Grade 1 Thickness.
18.50-24.99 ………………………… Normal Range.
25-29.99 …………………………… Grade 1 Over Weight.
30-39.99 …………………………… Grade 2 Over Weight.
≥ 40 ……………………………  Grade 3 Over Weight.

Thanks to all.

Environmental Pollution _Part 3_ How We Can Control Air Pollution.Key Points

Hi,
How Are You, Everybody???
If its answer is fine it is a good news for me. I am also fine by the grace of almighty.
In my chain post I will write on Air Pollution Control today.So read please.

Control of Air Pollution/ Protect Air from Being Polluted     

There are many ways by which we can control air pollution.They are:

*** Planting trees.

*** Reducing Carbon di Oxide (CO₂).

*** Controlling traffic jam.

*** Reducing the use of coal, gas, oil by replacing renewable energy(Sunlight,Wind etc).

*** Reducing the others gases(Such as.CO,SO₂ ).

*** Enlarging the chimney / Using Long Chimney.

*** Reducing the smoke generating from industries using technology.

*** Miscellaneous activities.

*** Our duties.  

Here Key points are only added. No description.

No more today.
The more when I will post next.
Thanks All.
Bye.Bye.

Environmental Pollution _Part 2_ Major Causes of Air Pollution

Hi,everybody
How are you???
Certain fine??? ok. I am also fine by the grace of almighty.
However,Now I want to discuss about the major causes of air pollution.

Major Causes of Air Pollution 

There are many causes for air pollution.They are given below.

*** Smoke created by industries  & factories
      It is one of the major causes for air pollution.Everyday industries & factories are emitting smoke which is poisonous & act as pollutants.The smoke mix with the air and pollute it.

*** Vehicles & Cars Smoke   
       It is the another cause of air pollution.The vehicles and cars create smoke & finally pollute the air of the environment. 

*** Burning of Oil,Coal & Others Natural Gas
       Burning of Oil,coal and others natural gas helps to pollute the air as it create different types of pollutants. 

*** Volcanic Activity
       Volcanic activity is one of the natural causes for air pollution.It create ash & release pollutants which make the air polluted.

*** Storm & Other Natural Disaster
        It also helps to pollute the air.

*** Miscellaneous 
       There are also some other causes for air pollution.Such as, smoking, smog(fog+smoke), burning wood etc.

Above all we should be careful about our environment.

No more today.
The more when we will meet in the next post.
Thanks all.

Environmental Pollution _Part 1_ Air Pollution Fundamental.

Hi everyboy,

How are you??? I am fine by the grace of almighty.

Today I will discuss about air pollution as fundamental.So start to read.

Environmental Pollution Part 1 

We live an environment. There is nobody who can live without environment. But it is a matter of great sorrow that our environment is being polluted day by day by various kinds of pollutants & things. Environment is polluted when it’s air, water,& soil is polluted at the same time or polluted as separately, both. Now I will discuss about the Air Pollution's fundamental.

Air Pollution

Air is one of the most important components of the environment. Without it, it is impossible to imagine an environment. But it is a matter of sorrow that, The air is being polluted day by day with different kinds of toxic substances. If we want to give a definition of air pollution we may say that 

“The mixing of pollutant , toxic & harmful substances into the air which can affect directly or indirectly to       human & animal & others of the environment.”

The pollutants, toxic & harmful substances may be smoke,dust, and any other poisonous things that is able to mix with the air very easily or gradually.

Green House Effect, Causes & it’s impact on Earth

Green House Effect, Causes & it’s impact on Earth

Green House Effect: The greenhouse effect  is a mechanism by which thermal radiation from earth surface is absorbed by atmospheric greenhouse gases(SO₂,CO₂  etc) and is re-radiated in all directions. Nowadays it is a common phenomenon in the world & it has a great impact on our environment.

Causes of Green House Effect: There are many causes of greenhouse effect. From which some are natural & majorities are human made. Man open pollutes the environment by emiting SO₂,CO₂  etc which are the culprits for greenhouse effect. On the other hands man open cutting down trees in a large  amount daily as comparing their plantation.Which is helping to increase Carbondioxide in the atmosphere. Pollution of the environment is also play a vital role for greenhouse effect.

Impact of Green House Effect: There are many impact of greenhouse effect on our environment. They are given below through different points.

           1.Global Warming: It is one of the common phenomena which is occurred due to Green House Effect. If Green House Effect is occurred in the environment, the ice of two pole of the earth (North & South pole) will be molten. Because greenhouse effect help to increase world temperature.

           2. Environmetal Pollution: Environmental pollution will be occurred if greenhouse effect is taken place.

           3. Obstacle to sustainable development of the environment: Green House effect also obstacle the way of sustainable development of the environment. It is damaging the way of sustainable development.

There are also other impact of Green House Effect on our environment & surroundings(such as Sea Level Rising). Above all we should be careful to our environment & try for a sustainable development of it.

Global Warming & Our Duties

Nowadays global warming is one of the common phenomena of the world. The scientists, researcher , and environmentalists prove that the temperature of the earth is increasing day by day. It occurs due to human activities & sometimes for nature. But man is the main culprit for this. We are using coal, fuel & cutting down trees highly as comparing their plantation that’s make the environment polluted. If we don’t take any step to control global warming, one day the lowest part of the earth will be sinked in the sea water as it help to increase sea level rise. So necessary steps should be taken to solve this problem. We can control global warming by planting trees, using renewable energies as much as possible, avoiding petroleum using and above all being conscious about our environment & surroundings. If we are conscious about our environment & do tasks which are necessary for our environment protection from global warming one day the earth will be sustainable for our living. So we should be conscious. Authorities should come forward to take steps against this problem. We should contribute  as our own..
