What are the disadvantages of using natural resources?

There is nothing wrong with using natural resources provided that it is done under supervision and not in an uncontrolled fashion. For the natural resources you describe, known as fossil fuels, obviously the generation rate is way slower than the rate at we consume them. This means that whatever we are doing now, is releasing excessive amounts of emissions into the atmosphere as compared to the amount that is deposited through natural processes.

For the above reasons, the first is obvious that there is only a limited quantity of fossil fuel, at least considering the portion which we can extract through current technology. The second is that since fossil fuel basically is highly concentrated energy stored in carbohydrates, the combustion or use of them releases carbon dioxide into the atmosphere. This can become an issue and accelerate the climate changes due to the green house effect. In addition, other toxics such as NOx and sulphur compounds are also released all which aid in the pollution of our environment.

However, on the other hand, besides the release of carbon dioxide, use of fossil fuel per se does not have to be anything bad. It is just that our society is overly dependent on it, thus resulting in risks both in terms of the environment but also political stability. Imagine what would happen if the oil supply chain originating mainly from overseas is cut off.

Using one source of power to generate another is simply a way of life, and always has been. There are many natural sources of power available. Man's ingenuity in converting one type of power to another has greatly improved our quality of life.

We have learned how to use natural gas, oil or coal to produce the electrical power needed by all in our country without creating the high levels of pollution that sometimes resulted in the past.

To eliminate this form of electrical power generation would put an end to the prosperity and abundance in our lives we all currently enjoy. We would no longer have enough electricity to refrigerate and preserve our food, cook our food, or heat and cool our homes. Life would not be how it is for you today.

There are several problems with using natural resources like fossil fuels. One big disadvantage is once you burn something like coal, it's gone. You can't get that coal back since it takes such a long time to form in the earth.

Burning fossil fuels also releases other gasses like carbon dioxide into the atmosphere. These greenhouses gases can cause global climate change and that's predominately seen as a negative thing. Burning other fossil fuels like coal can also release particulates into the air that can cause heart and lung problems. The burning of coal also releases mercury into the air and that can get into the food supply when we eat animals that have ingested the released mercury.

Some natural resources such as fossil fuels which include coal, gas and oil are a limited resource and will eventually run out. These resources are of much more use as a raw material for the manufacture of plastics and pharmaceuticals rather than being burnt in a thermal power station. Once they run out, we will have to find another source for these products.
When hydrocarbons are burnt in a thermal power station, they generate lots of carbon dioxide which is a greenhouse gas. Other pollutants such as sulphur dioxide and nitrous oxide are also produced which can result in acid rain.

Some obvious disadvantages:
- natural resources eventually will run out.
- we destroy natural habitats in order to obtain the natural resource

They often require more resources to harvest/produce than they end up saving in the long run. This is not always the case of course.
