Origin of the Earth
Our Earth is the only planet in our solar system with life. This living creature did not arise suddenly. It took millions of years to develop. Earth is believed to have formed 457 million years ago. After about 350 million years, life began to form. Expert studies suggest that microorganisms were formed in the sea in the beginning. Then the microorganisms in the soil were created. After that, gradually, plants and animals were created.
According to Darwin’s law, today’s human has evolved from a monkey. It took a period of thousands of years to evolve from the initially bent state to the erect human. Along with humans, other species of animals and plants came into existence. Ecosystems developed with all these living things.
Every living being has an equal need for survival. Human beings evolved more and more during this period. Compared to other living beings, humans have benefited from more intelligence. On the strength of this wisdom, man climbed one step in development. From a nomadic state he later came to a settled mode of life. He invented agriculture. This brought stability to his life. Forests were cut down for agriculture.
Various scientific discoveries started in Europe in the sixteenth century. This led to the industrial revolution and its spread throughout the world. Humans began to overuse natural resources for their own development.
Industrialization led to the uncontrolled emission of greenhouse gases. Fossil fuels began to be burned. Due to this, the emissions of these gases continued to increase. These gases prevent the sun’s heat from escaping back into the atmosphere. Therefore, the temperature of the earth is increasing.
Degradation of forests due to various reasons, such as the recent fires in the Amazon forest and the damage caused by the forest fires in Australia, is contributing to the increase in carbon dioxide. These forests are the world’s lungs, absorbing carbon dioxide and producing oxygen. We are eliminating them. With all this, we are endangering all living beings.
Due to the side effects of the temperature increase, many species of animals and plants have become extinct permanently, and some are on the verge of extinction. Due to the increase in temperature, the ice in Antarctica has started melting rapidly. Therefore, the sea level is rising. Some small islands have gone under water. Some are on the way.
Major coastal cities are also threatened in the future. Similarly, the number of disasters like droughts, floods, storms, and epidemics of different diseases has increased. The production of food grains is decreasing. The number of epidemics has increased due to the emergence of new viruses.
Due to all this, along with the entire human race, the entire living creation has come to the brink of destruction. All this needs to be taken seriously. It is necessary for all countries to come together to take measures against global warming and environmental balance. Developed countries should put their own egos aside and think about the welfare of the world first.
Causes of global warming
Global warming has become a serious issue that needs to be addressed. This is not happening for one reason but for many reasons. These causes are both natural and man-made. Natural causes include the release of greenhouse gases that cannot escape from the Earth, which increases temperatures.
Every small step, no matter how small, weighs heavily and is crucial to stopping global warming.
Q.1: List the causes of global warming.
Answer: There are various causes of global warming, both natural and man-made.
Natural gas includes greenhouse gases, gas from volcanic eruptions, methane gas, and more. Further, man-made causes include deforestation, mining, cattle ranching, the burning of fossil fuels, and many more.
Q.2: How can global warming be stopped?
Answer: Global warming can be stopped by the joint efforts of individuals and governments. Deforestation should be banned, and more trees should be planted. Automobile use must be limited and recycling encouraged.
It is a welcome fact that various countries have come together and signed various agreements to curb the emission of carbon dioxide. It is a matter of pride that India is the first in the world to take the first step for this. In 1969, a conference for environmental awareness was held in Delhi in collaboration with the “International Nature Conservation Organization.”
The first world conference was held in Stockholm, Sweden, on June 5, 1972, in terms of global efforts on environmental balance. India actively participated in it. Then, on June 1, 1992, the Earth Summit was held in Rio de Janeiro, the capital of Brazil. In 2002, the World Conference on Environment and Development was held in Johannesburg, South Africa. An important agreement was then signed in Kyoto, Japan, on December 11, 1997. It is called the Kyoto Protocol. It came into effect on 16 February 2005. It aims to “fight against global warming.”
It is important that humans wake up sooner or later. Just making a deal won’t do. Everyone should strive for their own earth’s environmental balance at the individual level. Vasundhara should flourish with biodiversity as before. For this, united efforts should be made for its conservation.
