The ocean is an example of a natural resource. Ocean waves can be used to generate wave power which is are newable energy. Ocean water is important for salt production and providing habitat for deep water fishes. There are biodiversity of marine species in the sea where nutrient cycles are common.



There are various methods of categorizing natural resources, these include source of origin, stage of development, and by their renewability, these classifications are described below. On the basis of origin, resources may be divided into:
Biotic – Biotic resources are obtained from the biosphere (living and organic material), such as forests, animals, birds, and fish and the materials that can be obtained from them. Fossil fuels such as coal and petroleum are also included in this category because they are formed from decayed organic matter.
Abiotic – Abiotic resources are those that come from non-living, non-organic material. Examples of abiotic resources include land, fresh water, air and heavy metals including ores such as gold, iron, copper, silver, etc.
Considering their stage of development, natural resources may be referred to in the following ways:
Potential Resources – Potential resources are those that exist in a region and may be used in the future. For example, petroleum may exist in many parts of India, having sedimentary rocks but until the time it is actually drilled out and put into use, it remains a potential resource.
Actual Resources – Actual resources are those that have been surveyed, their quantity and quality determined and are being used in present times. The development of an actual resource, such as wood processing depends upon the technology available and the cost involved.
Reserve Resources – The part of an actual resource which can be developed profitably in the future is called a reserve resource.
Stock Resources – Stock resources are those that have been surveyed but cannot be used by organisms due to lack of technology. For example: hydrogen.
Renewability is a very popular topic and many natural resources can be categorized as either renewable or non-renewable:
Renewable resources are ones that can be replenished naturally. Some of these resources, like sunlight, air, wind, etc., are continuously available and their quantity is not noticeably affected by human consumption. Though many renewable resources do not have such a rapid recovery rate, these resources are susceptible to depletion by over-use. Resources from a human use perspective are classified as renewable only so long as the rate of replenishment/recovery exceeds that of the rate of consumption.
Non-renewable resources are resources that form extremely slowly and those that do not naturally form in the environment. Minerals are the most common resource included in this category. By the human use perspective resources are non-renewable when their rate of consumption exceeds the rate of replenishment/recovery, a good example of this are fossil fuels which are in this category because their rate of formation is extremely slow (potentially millions of years), which means they are considered non-renewable from a human use perspective. Some resources actually naturally deplete in amount without human interference, the most notable of these are the radio-active elements such as uranium, which naturally decay into heavy metals. Of these, the metallic minerals can be re-used by recycling them.But coal and petroleum cannot be recycled.

 Stop Air Pollution

A major cause of concern today, air pollution, has made it a necessity to guide you through the ways to stop air pollution. Here is a guide to know the causes of air pollution as well as the measures to avoid it. Read and spread the word...

Air Pollution, the major cause of global warming, has raised a high alert all across the world. Different declarations are being made by the government implementing ways to stop pollution in order to have fresh air. Adhering to these ways will definitely help to stop air pollution and secure our lives. Now if you are thinking about how to stop air pollution; or what can we do to stop air pollution, here is a list of the best methods that you could implement to reduce and stop air pollution.

List of Ways to Stop Air Pollution

It is essential to know the causes of air pollution in order to look for methods to prevent them. So I would suggest you to go through some and then join me in prevention of air pollution by following some of these simple and effective ways to stop air pollution.
Save electricity. As doing so will help reduce the air pollution caused for its generation. Insulation of house with energy efficient equipment would save a lot of electric consumption. Use Compact Fluorescent Lights (CFLs) to save electricity. Switch off the lights when not of any use. You can use manual garden equipment rather than using an electric or gas-powered one. You should make use of fans or open windows for cool air as they are more beneficial than air conditioners. One of the air pollution facts is that air conditioners release harmful gas known as chlorofluorocarbons which leads to air pollution. Using solar equipment are considered as the best of all alternatives for conserving electricity.
When possible, walk or bike, or use roller blade or skateboards to close by work locations. Use of carpool or mass transit is also one of the most efficient ways to prevent air pollution. You can use other communication methods as well, instead of traveling all the way and losing out on fuel. Try to plan your small outings and get maximum of the work done in one trip.
Tailpipe emissions from vehicles is one of the most common and major reasons of air pollution. Service your vehicles on time and at regular intervals and always insist on cleaning air filters. Switch off your vehicles in case you halt at a place for more than 30 sec especially at railroad crossings, traffic signals, etc. One of the other ways to stop air pollution is to check the air conditioners used in vehicles at regular times in order to prevent leakage of CFC.
After you realize that your vehicle has turned old and is no more an efficient and pollution free vehicle, trade it for a newer model. New vehicles are pollution free and more efficient in protecting our environment. While driving any vehicle avoid accelerating too much.
You can convert a propane grill to natural gas to cook most of your party delicacies, which would help in tremendous reduction of other gases resulting in reduction of air pollution too.
Fires emit harmful gases in the form of smoke. This smoke pollutes the environment and may sometimes be very harmful to the lungs when inhaled. Hence, prevention of smoke and any kind of fire is very essential. That also includes the use of fireplace in homes.
You should make use of air pollution control equipment systems to keep a constant check on the pollution caused and further control the same.
Buy and use only products or goods that are marked recyclable, as they can be reused and help in reducing pollution. Can sprays should be avoided for any purpose, as they contain Chlorofluorocarbons (CFCs), a poisonous gas. Packing of goods consume a huge amount of electricity, and when burnt produces carbon dioxide as well as carbon monoxide further leading to be a greenhouse gas.
You should plant a tree every month or at least once a year to reduce the effects of air pollution. That will also help to maintain a cooling effect in your surrounding. You should use organic products while gardening and avoid raising dust while gardening or digging.
A few other ways to stop air pollution include using water based paints or paints categorized as zero-VOC for painting your interiors. While purchasing appliances like refrigerators, television, etc. you can check and buy low energy consuming ones. Instead of using a heater, you could dry your clothes on a clothesline in the backyard. Using brooms or rakes instead of blowers to clean your yard will help raise less amount of dust in the area.

We must remember that every individual, wherever he may be, can create a huge difference even in the smallest precaution taken by following these strategies. Saving energy at home can help protect our environment, as the old saying goes "First step to success starts at home." To help yourself and the future generation reap the benefits on this beautiful planet you got to adhere to the above mentioned tips. To keep yourself as well as the environment health it is also advisable to stop smoking, especially inside the house.

Changing your routine and following this list of ways to stop air pollution may be difficult, but is beneficial for us in the long run. So don't get too late to join us and spread this piece of information with your friends and family too. It's never to late to make a new start!! Good luck!

 Air Pollution

The article presents unto you different types of air pollution. Information about different ways in which air gets polluted and also related to causes is discussed below.

The problem of air pollution is a major concern in the 21st century and has resulted in degradation of the overall quality of life. Industrial revolution lead to the development of many sources which contribute greatly towards air pollution. Any substance/material that alters the natural composition of air in a negative manner can be termed as air pollutant. In an increasingly mechanized and industrialized world, rise in air pollution is bound to happen. The different causes of air pollution should be identified and measures taken to minimize it. Let us first understand what are the different types of air pollution through information presented below.

Different Types of Air Pollution

The industries and various modes of transportation continuously stay in operation. This results into the generation of pollutants in a far greater degree than other sources. The industrial, vehicular and dwelling-related pollution are 3 types of air pollution that are considered to be important. Different pollutants of air are discussed through types of air pollution in the paragraphs below.

Industrial Air Pollution
There are many factors which contribute to industrial pollution. The different industries which play an important part towards increasing the levels of air pollution are petroleum, cement, steel, thermal power plants, paper factories, atomic, pharmaceutical, sugar, other foods and pesticides.

Transportation and Air Pollution
The air pollutants viz., hydrocarbons and nitrogen oxides together with moisture present in air create smog. A hot and humid weather condition increases the chances of smog development. This problem resulting from vehicular emissions occurs in big cities. The emissions of vehicles also contain many poisonous gases that are harmful for health.

Pollution Resulting from Dwelling
The pollution resulting from dwelling are those caused by aerosols and other such chemicals. High density of population is also one of the causes of this type of air pollution.

Air Pollution Caused by Accidents
The causes of air pollution resulting from accidents are varied. Accidents could be anything like forest fires, blasts that occur in industries, etc. The accidents caused to vehicles which transport petroleum products also result into air pollution.

Types of Air Pollutants

The types of air pollution can also be determined on the basis of agents which pollute the air. Different air pollutants are discussed below.

Carbon Monoxide: The inhalation of carbon monoxide can be life-threatening. This is because the amount of oxygen that is being delivered to the tissues and organs of body gets reduced due to carbon monoxide. Other effects of air pollution resulting from carbon monoxide are dizziness and headaches.

Nitrogen Oxide: The percentage of nitrogen oxide pollution which results from vehicles is 34%. Out of the 34%, heavy diesel vehicles produce 42% nitrogen oxide, while the light vehicles including cars account for 52%. The remaining amount is contributed by other vehicles.

Hydrocarbons: Vehicles account for 29% hydrocarbon production. The hydrocarbons are responsible for health problems associated with respiratory tract. Lung tissues also get damaged by the inhalation of hydrocarbons.

Particle Matter: Transportation and industries are both responsible for production of particle matter. The majority of portion is however, contributed by industries. Particles (pollutants) in solid and liquid state together create a condition called haze. The air pollution facts for kids presented through above discussion should prove to be useful.

Information presented above, takes into account the mode/action which results into air pollution. Causes/pollutants responsible for air pollution must have also helped you understand its harmful effects. The different types of air pollution discussed in this article must have definitely helped you understand the importance of keeping the air clean. So get going and protect the environment to live a healthy life and maintain the same for future generations.
