Natural resources are
something that is occurring naturally on Earth. It forms an indispensable part
of our lives. It comprises of air, water, sunlight, coal, petroleum, natural
gas, fossil fuels, oil, etc. However, they are exploited by humans for economic
gain. Natural resources are at depletion because of the overuse. Some of these
resources are available in abundance with the capability to renew. On the other
hand, some are non-renewable. Thus, it demands a responsible behavior for the
conservation so as to ensure their sustainability.
Human beings depend upon
the natural resources for their development activities. If the resources are
not used wisely, it would create an imbalance in the environment. Thus would
head us in opposition to an eco-friendly atmosphere. The need for conservation
arises from the significance of natural resources. It is as follows. Water is a
renewable natural resource. We use it for drinking, producing electricity,
irrigation, in various industries and for a number of activities. Its scarcity
would cause loss of vegetation, adverse effect on flora and fauna, erosion of
soil, etc. Plants and animals provide a wide range of industrial and biological
materials. Also, it assists in the manufacturing of medicine and for various
other uses.
It takes millions of years for the formation of natural resources. Fossil fuels are of great importance. A lot of energy is produced from coal, oil and natural gas all of which are fossil fuels.
Forest is the most important natural resource which helps in economic development. Forest provides paper, furniture, timber, medicine, gum, etc. Also, it maintains a balance in the ecosystem. Moreover, it prevents soil erosion and protects wildlife. Land resources support natural vegetation, wildlife, transport. The land also provides us food, cloth, shelter, and other basic needs.
Different ministries of governments , national and international agencies have been working for the purpose of conserving the natural resources. Environment education must be imparted by including the same in the curricula of the schools. National parks are making an effort for the safety of the natural resources. By reducing, reusing and recycling of non-renewable resources.
Non-human
species must be disturbed only to meet the basic needs. Planting of more and
more trees to save our forest resources. There are ways for seeking
alternatives to non-renewable resources. 1 -] By increased use of bio-gas and
bio-fuels. 2- ] By preventing the dumping of industrial wastes into the river
bodies. This is a measure to protect the rich marine life. 3-] Overgrazing must
be prevented. 4 - ] Also, poaching of animals must be controlled. 5 - ] Practicing
crop rotation techniques helps in maintaining the fertility of the soil.
Burning of fossil fuels
emits carbon-di-oxide which is a major greenhouse gas. It is responsible for
the greenhouse effect. Thus, the burning of fossil fuels must be controlled. These
are some of the measures which we can undertake for the conservation of natural
resources. As Human- beings, we have a social responsibility to fulfill towards
nature. Thus, while using resources, we shall follow the principle of
sustainable development. Natural resources are a present for the creation.
These help in satisfying the human needs to its fullest. Furthermore, the
rational use of natural resources maintains the earth’s atmosphere. Also, the
wise use leads to protection of bio-diversity. Humans cannot imagine their
lives without natural resources. Thus, the conservation of the same is
essential.
119 - ) Acid Rain
Acid Rain includes
rain, snow, hail, fog, or dew that is high in acid pollutants, especially
sulphuric and nitric acid. Acid Rain is mainly caused by emissions of sulphur
dioxide and nitrogen oxide from various sources. They react with the water
molecules in the atmosphere to produce acids. The problem of Acid Rain has not
only increased with rapid growth in population and industrialization, but it has
also become more harmful. In fact, the use of the tall chimneys on a factory,
ship, has contributed to the spread of Acid Rain by releasing gases into the
atmosphere. A large number of acid deposits are witnessed in Canada, the United
States, Europe , portions of Sweden, Norway, and Germany. Some amount of acid
deposits are found in parts of South Asia, South Africa, Sri Lanka and Southern
parts of India like Bangalore, New Delhi, Mumbai.
There are two types of depositions in which acid rain occurs. They can be discussed as follows: 1- ] Wet deposition: When the acid falls on the ground in the form of rain, snow, fog or mist, it removes acid from the atmosphere and settles them on the Earth’s surface. When this acid flows through the ground, it affects a large number of plants, animals and aquatic life. The water from drain flows into the water sources like rivers and canals which is then mixed up into seawater; thereby affecting the aquatic habitats. 2 - ] Dry deposition: When the acidic pollutants merge into dust or smoke and fall to the ground as dry particles, these stick to the ground and other surfaces such as buildings, cars, houses, trees, and monuments. Majority of the acidic pollutants in the atmosphere spread through dry deposition.
The major causes of acid rain are Natural and Human-Instigated causes. However, Acid Rain is basically caused due to the combustion of fossil fuels which results in emissions of sulphur dioxide (SO2) and nitrogen oxide (NO2) in the atmosphere. The main nature causing agents for acid rain are volcanic eruptions. Volcanoes emit a large amount of lava, producing harmful gases which create a higher than normal amount of Acid Rain. Decaying vegetation, wildfires and other biological processes within the environment also generate the Acid Rain forming gases. Lighting strikes also produce nitric oxides that react with water molecules via electrical activity to produce nitric acid, thereby forming acid rain.
Human activities leading
to the emissions of chemical gas include sulphur and nitrogen gases from the
factories, power generating premises and automobiles. Mainly, the use of coal
for electrical power generation is the biggest contributor to gaseous
emissions. These also lead to acid rain. These gases react with water, oxygen,
and other chemicals to form various acidic compounds such as sulphuric acid,
nitric acid, etc. As a result, those areas experience exceedingly high amounts
of acid rain.
Acid Rain
adversely affects the environment includes marine biodiversity, soil,
architecture & infrastructure, forests, and forest wildlife, public health.
For example, Taj Mahal is turning yellow mainly due to air pollution,
discoloration of marble due to oxidation of its constituents is one of the
harmful effects of acid rain.
Acid Rain caused due
to the natural reasons cannot be stopped. But there are ways following which we
can avoid the same, caused due to man-made reasons. The ways by which acid rain
can be avoided are by the use of limestone by which people can repair the
damages caused by acid rain to lakes, rivers, brooks, and other water sources.
By adding lime into acidic surface also we can avoid acid rain as water
balances the acidity.
Use of hybrid vehicles
with negligible NO2 emissions is also a way out. Besides fossil fuels, there is
a wide range of substitutable energy sources that can generate electrical power
these include wind energy, solar energy, geothermal energy, nuclear power, and
hydro energy. Using these energy sources can offer effective electrical power
alternatives. Instead of using fossil fuels, use of natural gas, fuel cells and
batteries can also substitute use of fossil fuels. As you can see, there are
many attempts to clean our air. Due to increase in population and rapid
industrialization, we need to make efforts on a war footing to reduce the
phenomenon of Acid Rain. The whole world needs to take a call to avoid
inflicting colossal damage to the environment.
