Impact of Car Pollution on the Environment

There are millions of cars on our roads and each one of them is a potential contributor to environmental pollution. Cars emit poisonous gases which impact the environment apart from causing numerous life-threatening diseases in human beings. Let us know more about the impact of car pollution on the environment.

We all know the effects of pollution on the environment. We have watched various documentaries, have read several books and have been to several debates on the issue of environmental degradation. However, most of us are equally responsible for this, and in fact, we contribute daily to environmental pollution. How? Well, studies have shown that automobiles are the biggest source of pollution in cities, and have contributed immensely to air and noise pollution. The pollutants that are emitted from the exhaust of a car contain various toxic substances and cause various life-threatening diseases in humans. These pollutants are harmful for birds and plants, and disturb their natural process. Let us know more about the impact of car pollution on the environment.

Car Pollution Effects

• The exhaust from the cars contains various greenhouse gases such as carbon monoxide and nitrous oxide. These gases have an ability to block the sun-rays that are reflected from the earth's surface. This solar energy gets trapped in the earth's atmosphere and causes variances in temperature. This is one of the major contributors to global warming. According to estimates the global temperatures have seen a drastic increase in the last hundred years and if we continue adding up millions of cars every year to our roads, the temperature will increase rapidly, posing a threat to the survival of human race on this planet.
• Most cars are manufactured to achieve perfect combustion of fuel but after some time as the car undergoes wear and tear, the engine is not able to function efficiently which results in the emission of toxic substances. These pollutants are harmful for living beings and cause a host of respiratory diseases and lung cancer in humans. These toxic gases can also destroy plants, which are an important constituent of the ecological cycle.
• One of the greatest threats that car pollution has posed to the environment is the depletion of ozone layer. Ozone layer prevents harmful Ultra-Violet (UV) rays from reaching our atmosphere. The UV rays can cause a host of diseases and can change the genetic make-up of living beings. Although chlorofluorocarbons (CFC) have been banned from use in automobiles, countries where regulations are less stricter are still using it unabatedly.
• Pollution from cars has also impacted the quality of water, as smoke from the exhaust combines with rain, leading to acid rain, which makes its way to oceans and seas. Oil, which is released from cars due to leakage mixes with storm-water and pollutes the natural resources of water.
• Cars have increased the decibel levels in the environment which has contributed immensely to noise pollution. Noise pollution has caused a disturbance in the ecological cycle and many animals have had behavioral issues because of high noise levels. Apart from impacting the environment, noise pollution can cause several diseases in humans, such as high blood-pressure and mental stress.
• Cars have occupied major portions of our cities and this has contributed to land pollution. Vast areas of barren lands have been turned into parking lots and more are being created to accommodate the growing number of cars that are being added each day.

These were some ways in which cars have contributed to environmental pollution. It has been seen that instead of taking responsibility to conserve the environment, we pass the buck to environmental activists. If we cannot fight for environmental causes, we can at least make sure that we are doing our bit to prevent the degradation of the environment. Avoiding the use of a car for short journeys can reduce the pollution levels in the environment. Also, cars that are not properly maintained emit pollutants in higher amounts, so it is necessary to take proper care of the car through regular servicing. It not only helps in preventing pollution but it also increases the life of your car. If each one of us contributes a little bit, it certainly will make a big difference to environmental conservation.

Classification of Natural Resources

Natural resources are naturally occurring substances that are considered valuable in their relatively unmodified (natural) form. A natural resource’s value rests in the amount of the material available and the demand for it. The latter is determined by its usefulness to production. A commodity is generally considered a natural resource when the primary activities associated with it are extraction and purification, as opposed to creation. Thus, mining, petroleum extraction, fishing, hunting, and forestry are generally considered natural-resource industries, while agriculture is not. The term was introduced to a broad audience by E.F. Schumacher in his 1970s book Small is Beautiful.


Classification of natural resources
Natural resources are mostly classified into renewable and non-renewable resources. Renewable resources

Renewable resources are generally living resources (fish, reindeer, coffee, and forests, for example), which can restock (renew) themselves if they are not over-harvested but used sustainably. Once renewable resources are consumed at a rate that exceeds their natural rate of replacement, the standing stock (see renewable energy) will diminish and eventually run out. The rate of sustainable use of a renewable resource is determined by the replacement rate and amount of standing stock of that particular resource. Non-living renewable natural resources include soil and water.

Flow renewable resources are very much like renewable resources, only they do not need regeneration, unlike renewable resources. Flow renewable resources include renewable energy sources such as the following renewable power sources: solar, geothermal, biomass, landfill gas, tides and wind.

Resources can also be classified on the basis of their origin as biotic and abiotic. Biotic resources are derived from living organisms. Abiotic resources are derived from the non-living world (e.g., land, water, and air). Mineral and power resources are also abiotic resources some of which are derived from nature.

Non-renewable resources

A non-renewable resource is a natural resource that exists in a fixed amount that cannot be re-made, re-grown or regenerated as fast as it is consumed and used up.

Some non-renewable resources can be renewable but take an extremely long time to renew. Fossil fuels, for example, take millions of years to form and so are not practically considered ‘renewable’. Many environmentalists proposed to tax on consumption of non renewable resources.

Natural capital

Natural resources are natural capital converted to commodity inputs to infrastructural capital processes. They include soil, timber, oil, minerals, and other goods taken more or less from the Earth. Both extraction of the basic resource and refining it into a purer, directly usable form, (e.g., metals, refined oils) are generally considered natural-resource activities, even though the latter may not necessarily occur near the former.

A nation’s natural resources often determine its wealth and status in the world economic system, by determining its political influence in. Developed nations are those which are less dependent on natural resources for wealth, due to their greater reliance on infrastructural capital for production. However, some see a resource curse whereby easily obtainable natural resources could actually hurt the prospects of a national economy by fostering political corruption. Political corruption can negatively impact the national economy because time is spent giving bribes or other economically unproductive acts instead of the generation of generative economic activity. There also tends to be concentrations of ownership over specific plots of land that have proven to yield natural resources.

In recent years, the depletion of natural capital and attempts to move to sustainable development have been a major focus of development agencies. This is of particular concern in rainforest regions, which hold most of the Earth’s natural biodiversity – irreplaceable genetic natural capital. Conservation of natural resources is the major focus of natural capitalism, environmentalism, the ecology movement, and Green Parties. Some view this depletion as a major source of social unrest and conflicts in developing nations.Other information sources.

The rainforest on Fatu-Hiva, Marquesas Islands is an example of an undisturbed natural resource. Forest provides timber for humans; food and shelter for flora and the fauna. The nutrient cycle between organisms form food chains and biodiversity of species.
