Why Coral Reefs are important?

coral important

Coral Reefs are one of the most biologically diverse marine ecosystems on the earth.

These are found in the shallow tropical areas where the seawater is clean, clear, and warm and spreads in a large area having rich species diversity.

Coral Reefs are important due to the following reasons.

1. Ecologically, coral reefs are important because they are the counterpart to the tropical rain forest in terms of biological productivity in the Ocean and species diversity.
2. Coral Reefs are natural protective barriers against erosion and storm surge.
3. They provide habitat for a large variety of plants and animals.
4. Coral reefs provide an accurate long-term record of climate change by helping in determining the climate variability in remote tropical oceans and thus are climatologically important.
5. Coral Reefs provide substrate for mangroves.
6. They help in the formation of associated eco-systems which allow the formation of essential habitats, fisheries, and livelihoods.

Is Ozone a Pollutant?

ozone

The simple answer to this question is yes and no.

Ozone is a pollutant when it is found in the Troposphere (also known as ground-level ozone). Surface level ozone is also the third most potent greenhouse gas after carbon dioxide and methane.

On the other hand, Ozone acts as a shield in the Stratosphere where it protects us from harmful Ultra violet radiations of the Sun.

How is Bad Ozone formed?

The Ozone found in the Troposphere is known by different names such as Bad Ozone, Ground Level Ozone, etc. It is man-made ozone found near the surface of the earth (Troposphere).

Bad Ozone is formed during high-temperature conditions of late spring, summer, and early fall, when high levels of ozone are usually formed in the heat of the afternoon and early evening, dissipating during the cooler nights.

The released gases such as nitrogen oxide (NOx), carbon monoxide (CO), and volatile organic compounds (VOC) combine chemically with oxygen to form ozone during sunny days near the surface of the earth.

NOx, CO, and VOCs are known as ozone precursors as they combine with oxygen to form ozone.

This bad ozone combines with Particulate Matter (PM) 2.5 to form smog.

Effects of Bad Ozone

Being harmful and a greenhouse gas, Bad Ozone has many ill effects on the environment as well as to the human health.

1. Higher rates of pulmonary (related to lungs) disease.
2. Irritation to the skin and the respiratory system
3. Sufficient ozone, when enters the leaves of a sensitive plant, can reduce photosynthesis and slow the plant growth.
4. Damages some types of materials, especially objects made of rubber.
5. As a potent greenhouse gas, it is largely responsible for the warming of the surface of the earth.

Ozone is found in which layer?

ozone

Ozone is a gas that is found in both Stratosphere and Troposphere. Ozone is of 2 types.

One that is found in the lower Stratosphere where it acts as a layer that protects the earth from the harmful Ultra Violet radiations of the Earth.

The other is found near the surface of the earth (Troposphere) where it acts as a pollutant and a potential greenhouse gas.

Layers of Earth Atmosphere

Earth’s atmosphere is broadly divided into 5 layers. These are –

LAYERS RANGE
1. Troposphere0 – 13 km
2. Stratosphere13 – 50 km
3. Mesosphere50 – 85 km
4. Ionosphere85 – 700 km
5. Exosphere700 – 10,000 km

Black Soil in India and its importance

black soil

Black soil, also known as ‘Regur Soil’ or the ‘Black Cotton Soil’ is highly productive and fertile soil found in India.

Key features of Black Soil in India

1. Black soil covers most of the Deccan Plateau which includes parts of Maharashtra, Madhya Pradesh, Andra Pradesh, Gujarat, and some parts of Tamil Nadu.
2. These soils are generally clayey, deep, and impermeable (doesn’t allow water to pass through it).
3. The color of these soil ranges from deep black to grey.
4. They swell and become sticky when wet and shrink when dried.
5. This gives rise to wide cracks during the dry season and hence these soils are kind of ‘self ploughing’ soils.
6. Black soil displays the characteristics of slow ‘absorption’ and a slow ‘loss of moisture’ which helps in retaining moisture for a very long time and thus helps the crops, especially, the rain-fed ones, to sustain even during the dry season.
7. The black soils are rich in lime, iron, magnesia, and alumina. They also contain potash.
8. They lack in phosphorous, nitrogen, and organic matter.

Important terms in the Preamble of the Indian Constitution.

Following are the most important terms in the preamble:

Sovereign

Sovereign means the independent authority of a State. It means that it has the power to legislate on any subject; and that it is not subject to the control of any other State or external power.

India is a sovereign country and no external power can dictate the government of India about its functions.

India is externally free from the control of any foreign power and internally, it has a free government that is directly elected by the people from the people itself and makes laws that govern the people.

Socialist

The term socialist as used in the preamble refers to democratic socialism which is the achievement of socialist goals through democratic, evolutionary and non-violent means.

It is an economic philosophy where means of production and distribution are owned by the State thus emphasizing social equality.

India has adopted a system of a mixed economy where the public and private sector co-exists.

Secular

Secular means that the State is neither allied with nor against any particular religion.

In other words, Indian State has no particular religion and all persons will be equally entitled to the freedom of conscience and the right freely to profess, practice and propagate the religion of their choice. (SR Bommai and Others v Union of India, AIR 1994 SC 1918).

Democratic

The word ‘democratic’ not only refers to political but also to social & economic democracy.

The people of India elect their governments by a system of universal adult franchise, popularly known as “one person one vote”. Every citizen of India 18 years of age and above and not otherwise debarred by law is entitled to vote.

The government is elected by the people, from the people, and for the people.

Republic

In a republican form of government, the head of state is elected directly or indirectly, for a fixed tenure.

This is contrary to the monarchy system of government where the head of the state is appointed on the hereditary basis for a lifetime or until he abdicates from the throne.

Thus, this word denotes a government where no one holds public power as a proprietary right. India has a President who is elected and has a fixed term of office.

Justice

India seeks to ensure social, economic and political justice to ensure equality to its citizens.

(i) Social Justice:

Social Justice means the absence of socially privileged classes in the society and no discrimination against any citizen on grounds of caste, creed, color, religion, gender or place of birth. India stands for eliminating all forms of exploitation from society.

(ii) Economic Justice:

Economic Justice means no discrimination between man and woman on the basis of income, wealth and economic status. It stands for equitable distribution of wealth, economic equality, the end of monopolistic control over means of production and distribution, decentralization of economic resources, and the securing of adequate opportunities to all for earning their living.

(iii) Political Justice:

Political justice means equal, free and fair opportunities to the people for participation in the political process. It stands for the grant of equal political rights to all the people without discrimination. The Constitution of India provides for a liberal democracy in which all the people have the right and freedom to participate.

Liberty

The idea of Liberty refers to the freedom of the activities of Indian nationals. It implies the absence of restraints or domination on the activities of an individual such as freedom from slavery, imprisonment, etc.

However, liberty does not mean freedom to do anything, and it must be exercised within the constitutional limits.

Equality

Equality means that no section of the society enjoys special privileges and individuals are provided with adequate opportunities without any discrimination.

The Preamble provides for equality of status and opportunity to all the people of the country. Here, the constitution provides social, economic and political equality to all the citizens. All are equal before the law.

Fraternity

Fraternity means a feeling of brotherhood and a sense of belonging with the country among all the citizens of the State. It leaves no room for regionalism, communalism, casteism, etc., which hinders the unity of the State.

The Preamble declares that fraternity has to assure two things—the dignity of the individual and the unity and integrity of the nation. The word ‘integrity’ has been added to the Preamble by the 42nd Constitutional Amendment (1976).

Amendments in Preamble of the Indian Constitution

The Preamble was amended by the 42nd Constitutional Amendment Act 1976, which added three new words namely – socialist, secular and integrity. The Preamble has been amended only once till now.

Hence, the Preamble of the Indian constitution is a powerful piece of text that contains the basic ideals, objectives and the grand and noble vision of the Constituent Assembly. It reflects the vision and aspirations of the founding fathers of the Constitution which embodies the political, moral and religious fundamental values, on which the constitution is based.
