Every year on April 22, the world is celebrated around the world "World Darish Day" or "Earth Day". This is a day when people realize the importance of protecting the environment, nature and the earth and take various programs to raise awareness. As the modern civilization progresses, the pressure on nature and the environment is increasing. On this day the people of the world are committed to keeping the world more habitable, green and sustainable. People from different countries are also regularly participating in this movement. The industrialized country has given the example of the envelope through discussion and writing. They are fighting to reduce carbon emissions to keep the earth habitable. The arrows of their complaint are on the industrialized countries. Originally industrialized countries are the protagonist behind the environmental warming of the environment. Environmental catastrophe has caused great environmental disaster all over the world as a result of large factories, nuclear reactors, indiscriminate forests, rivers, etc. CFC gas, carbon dioxide and carbon monoxide gas emissions have increased due to the envelope of industrialized countries. The gas that is released as a filter of the earth is diluted and the surface of the earth is gradually becoming thinner. That is, the ozone layer is failing to send the temperature of the earth to the temperature of about 1 lakh 15 thousand degrees Celsius in the sun. Note that a balanced temperature for the earth is 10-42 degrees Celsius (may be low). But that balanced temperature is no longer prevailing, but the opposite is happening. Gradually, the earth is becoming heated by the end of the ice age. The temperature has risen to 63 degrees Celsius. A few years ago (on 8 June 2019 ), the Kuwait temperature created a world record. In Kuwait, the maximum temperature rose to 63 degrees Celsius. The wheels of the car have also melted in that heat. The surprising thing is that in the shaded area there was a temperature of 52 degrees Celsius. At that temperature it is difficult for a human being to survive. For example, the temperature starts to boil at 70 degrees Celsius, in which case the 63-70 degrees are very close. So we can say that this is a terrible signal for the world. In every life of nature, humans are just a life. There are also billions of lives in the world, which helps to save our lives. So we have to create an atmosphere of survival. In order to sustain the earth, we need to be respectful of inter -dependent souls and nature. We have a blue planet where there are about 80 million people and billions of animals. There are rivers, mountains, mountains, sea, desert, waterfalls. Our person has given us all the air, water, food, and all the living materials for living. Today, we are threatened by a habitable climate change. Due to environmental catastrophe, such intense heat flux on the one hand and severe winter or floods, drought, storms, rain, tides or fires today are overwhelming. The human activities are very responsible for them. Extravi people have abused the wealth of nature. The mountains and mountains, the forests have been cut off. The rivers, canals-bills, reservoirs have established habitat and industrial factories. Due to the decline in the forest, the amount of rainfall is decreasing and the heat flux is increasing. The heat flux of April this year reminds us that our festival is heating up day by day. The human body is getting tired of the intense heat wave. Water crisis is appearing in various reservoirs of the country. In order to protect against climate disasters, global temperatures need to be kept 1.5 degrees Celsius. On top of this, the animal is less likely to survive.

 

> History of World Day:

World Dharma Day was first celebrated in the United States 22 April. US Senator Gelord Nelson started this day. He felt the need to create a mass awareness against environmental pollution, forest degradation, destruction of wildlife and abuse of natural resources. About 2 million people participated in that first day of the 1970th. Since then it has been celebrated every year, and today it has spread to more than 190 countries.

 

> The importance of this day:

World Daily Day reminds us that we are not safe if we are part of nature and we are not safe. It is not only a global movement to maintain the environmental balance of the tree or to maintain cleanliness.

 

* Global warming or global warming * Air and water pollution * Forests * plastic pollution * Biodiversity erosion is the main focus of the discussion of these issues. On this day various seminars, rallies, tree planting programs and awareness campaigns were carried out.

 

> In the current context, Dhritri Day:

Climate change in the present world has become a major threat. Every year, the rate of warmth is rising, ice is melting, sea level is rising, forests are being destroyed, and new diseases are occurring. South Asian countries, including Bangladesh, are one of the risks of this changeWorld Darish Day is therefore to take initiative at a personal, social and state level to solve these problems. As:

 

* Use of renewable fuel * Use recycling content * planting trees and conservation of forests * Controls pollution in industries

* Biodiversity conservation * Use of environmentally friendly technology

 

> In the context of Bangladesh:

Bangladesh is a climate-risky country. Every year, natural disasters such as floods, cyclones, rivers, droughts, etc. are regularly seen here. The effects of environmental imbalances and climate change are behind these disasters.

 

The government of Bangladesh and various NGOs are taking initiatives to protect the environment. Environmental awareness education has been introduced in schools and colleges. Environmental Protection Act has been enacted. However, the participation of the people is the most important in this regard.

 

> Our role in conservation of the environment:

Dhritri Day is not just a day, it is the name of a responsibility. We can do a lot for the environment by developing some simple habits in our daily life. Eg: _ stopping water waste * Save electricity * Keep your home and neighborhood clean

* Using clothes or paper bags instead of plastic * Avoiding unnecessary travel * Trees planted and taken care of

 

> Education and Education Day: On World Dharma Day, awareness was created among the students through various types of competitions such as writing, painting, poster preparation, discussion meeting, drama etc. in school, college and university. The students are the leadership of the future, so they have to build their nature -loving and environmentally friendly.

 

> UN and Global Initiatives:

The UN has signed several important agreements and conferences to prevent climate change. The Kyoto Protocol, the Paris Agreement and the COP Conferences are part of the global planning of the environment. Through these, the countries are working to meet the scheduled goals. However, it is impossible to meet these goals without the participation of the common people, not just the government.

> On this year's Datri Day, let's not know some great information about this world.

 

* Earth is not completely round

Our world is generally described as round, but it is not really round. The earth is a bit pressed to the two poles, so more correctly, the earth is actually sub-evident. And like all planets, the influence of the central power caused by the power of gravity and its axis on one's axis is somewhat flattened, and the equatorial region is somewhat wide. This is why the diameter of the earth along the equatorial line is 43 km more than the diameter of the other along the other pole.

* 70 percent of the earth's water

Water is on the earth, liquid and aerial- in three forms of the world. Besides, three quarters of the surface of the world are covered in water, which is in the form of glaciers, wetlands, lakes, rivers, seas or oceans.

 

* From where space or space begins

The beginning of space or space from one hundred kilometers above the world. The boundary of the weapon and space is known as the carman line, which is one hundred kilometers above the sea.

 

* The center of the earth is formed mainly with iron

Earth is the fifth largest planet in the solar system. The most interior of the earth is considered to be like a nerd ball. Its radius is about twelve kilometers. It is mainly made of iron, which is about 85 percent of its weight. And there is nickel, which is about ten percent of this nerd ball.

 

* Earth is the only planet where there is life

In this universe, the earth is the only novelist, where we know that life exists. The number of species of animals listed on earth is now 12 lakhs. Even though it is considered a small part of the total animal. In 2011 scientists have speculated that there are about 87 million species in the natural worldThis earth was formed about four decimal five billion years ago and because of its wealth, geological history and its orbit, the existence of life has survived for millions of years.

 

* Gravity is not equal to the world everywhere

Since our world is not in perfect sphere shape and its mass is not equally wide everywhere, the field of gravity and energy also varies in different places. Such as, when we move from the equator to the pole region, the intensity of gravity energy increasesHowever, it is not possible for humans to feel the difference of this energy.

 

* Earth is the planet of extreme variations

This world is full of extreme contradictions. Due to the geographical and climate variations, each region has some strange features. However, the highest temperature in the world has been recorded in the US Death Valley so far. The temperature was recorded on the thermometer on 10 July 1 913 .56.7 degrees Celsius. Antarctica is in contrast. On July 31 the temperature came down on the devastation of the station at Mainus at 89.2 degrees.

 

* The largest structure of living life on the earth

The Great Barrier reef on the coast of Australia is the single largest structure of living life on earth. It is so big that it can be seen from spaceAbout two thousand kilometers, the reef lives in numerous marine species.

 

* There is only an active tectonic plate in the solar system that is the only planet where active tectonic plate existsDue to the movements of these plates, the earth's surface is constantly changing. These plates have a role in the formation of mountains and mountains in the world. They cause earthquakes, eruptions from volcanoes. These plates play an important role in controlling the earth's temperatureGreenhouses like carbon dioxide helps recycling gas.

 

* The Earth has a protection shield

The magnetic field of the earth serves as a shield to protect the high levels of sun from particlesThis magnetic field, from the interior of the elaborate earth to the outspoint, where it comes in contact with solar wind. This magnetic field helps many animals to find a way. It also helps us to direction through compass.

Finally, I want to say that we have a moral responsibility as a conscious person in protecting it. We need to work together to protect the environment not only for us but the next generation to survive healthy and beautifully. ”So

We believe that the world has enough opportunity to highlight the above issues through the celebration of World Day. The industrialized countries will be interrupted to some extent in their activities. So we can say that the importance of the World Day is compared to other days of the day, so we call it important to highlight the significance of the day. Various programs were also organized on this day to raise awareness about the global climate crisis and the deterioration of the environment.
