जागतिक तापमान वाढ - मराठी निबंध | Global warming essay in Marathi

जागतिक तापमान वाढ 

"निसर्गाशी नाते जोडुया, 

जागतिक तापमान वाढीला दुर पळवुया."

प्रस्तावना -

 'आधुनिक काळात जागतिक तापमान वाढीची  समस्या संपूर्ण मानवजातीसाठी चिंतेचा विषय बनली आहे. पण जागतिक तापमान वाढ ही अशी समस्या आहे की ती एकदा वाढली की मग तिचा समतोल राखणे फार कठीण होऊन बसते. शास्त्रज्ञांचे असे मत आहे की जर जागतिक तापमान वाढीवर नियंत्रण ठेवले नाही तर येणाऱ्या काळात या पृथ्वीवर राहणे अशक्य होईल. 

जागतिक तापमान वाढीचा अर्थ - 

औद्योगिक क्रांतीपासूनची सरासरी जागतिक तापमान वाढीला ग्लोबल वॉर्मिंग म्हणतात. सर्वसाधारण शब्दात, ग्लोबल वार्मिंग म्हणजे प्रदूषणामुळे पृथ्वीच्या तापमानात होणारी वाढ. या समस्येमुळे आपली पृथ्वी दिवसेंदिवस गरम होत चालली आहे. यावर नियंत्रण ठेवले नाही तर येणाऱ्या काळात या पृथ्वीवर राहणे अशक्य होईल. वाढत्या जागतिक तापमानामुळे चक्रीवादळ, पूर, जंगलातील आग, दुष्काळ आणि उष्णतेच्या लाटा यांचा धोका वाढतो. 

जागतिक तापमान वाढीची करणे -

जागतिक तापमान वाढीची अनेक करणे आहेत जसे की, अंदाधुंद जंगलतोड, गरजेपेक्षा जास्त आधुनिकीकरण, लोकसंख्येचा स्फोट, औद्योगिकीकरण, विविध प्रकारचे प्रदूषण, हरितगृह परिणाम इ. जेव्हा हरितगृहामध्ये कार्बन  डायऑक्साइड, मिथेन आणि पाण्याची वाफ यांसारख्या वायूंचे प्रमाण आवश्यकतेपेक्षा जास्त वाढू लागते, तेव्हा ते पृथ्वीचे तापमान आवश्यकतेपेक्षा जास्त वाढवते.काही कारणे सोडली तर जागतिक तापमान वाढीच्या समस्येचे मुख्य कारण मानवनिर्मित आहे. ही समस्या वेळीच सोडवली नाही, तर तो दिवस दूर नाही जेव्हा तो मानवतेच्या विनाशाचे कारण बनेल.

ग्लोबल वॉर्मिंगचे परिणाम-

हवामानातील बदल, अतिउष्णता, समुद्राच्या पातळीत वाढ, नैसर्गिक आपत्ती, ओझोनच्या थराला छिद्र इत्यादी जागतिक तापमानवाढीचे परिणाम आहेत.वाढत्या जागतिक तापमानामुळे चक्रीवादळ, पूर, जंगलातील आग, दुष्काळ आणि उष्णतेच्या लाटा यांचा धोका वाढतो. 

समस्येवर उपाय- 

जागतिक तापमान वाढ टाळण्यासाठी जास्तीत जास्त झाडे लावा आणि जागतिक तापमान वाढेल असे उपक्रम करू नका किंवा कमी करा. आपण हरितगृह वायूचे उत्सर्जन कमी केले पाहिजे. सरकारी एजन्सी, व्यवसाय प्रमुख, खाजगी क्षेत्र, N.G.O. इत्यादि कडून जागतिक तापमान वाढ कमी करण्यासाठी  अनेक कार्यक्रम राबवले जात आहेत.

"जेव्हा पृथ्वीचे तापमान सामान्य असेल,

 तेव्हा आपली पृथ्वीही स्वर्गासारखी बनेल."

Global warming 

     Global warming is very harmful for environment. We know that Global warming is one of the biggest issues faced by the world. Global warming refers to the rapid increase in Earth's temperature. We have also started facing its effects in recent times. 

     The prime cause of global warming is the greenhouse effect. The greenhouse effect is caused due to the gases which absorb and reflect radiant energy. The gases responsible for the greenhouse effect are called the Green House gases.

     The greenhouse gases when present in moderate quantities, help earth retain the heat received from sunlight. Thus, helping in maintaining moderate temperature necessary for survival of life on earth.

     But human activities such as industrialization, deforestation and environmental pollution causes increase in the greenhouse gases. This increase in greenhouse gases results in more heat being trapped on earth's surface. Thus, increasing the average temperature and causing Global warming.

     The consequences of global warming are widespread and potentially disastrous. The rise in sea levels threatens to inundate coastal cities and cause mass migration. Extreme weather events such as hurricanes, droughts, and floods can result in loss of life and property damage. Changes in climate can also negatively affect agriculture and natural ecosystems.

     There have been many campaigns organized by United Nations and other countries to fight global warming. Several agreements have been signed by many countries to reduce the greenhouse gas emission. There are many ways by which we can prevent the occurrence of global warming.

     To combat global warming, individuals, governments, and businesses must take action to reduce greenhouse gas emissions. This can be done through a variety of methods, including using renewable energy sources, reducing waste, and promoting energy efficiency. By taking action now, we can help to mitigate the effects of global warming and ensure a sustainable future for upcoming generations.

“Climate change is a terrible problem,

 and it absolutely needs to be solved.

 It deserves to be a huge priority.” 

Essay on Environmental Pollution for students in English | 150 to 200 words

                                    Environmental Pollution

          Environmental pollution is one of the most pressing issues facing the world today. It refers to the presence of harmful substances or pollutants in the natural environment, which can have a harmful effect on the environment and on living organisms. There are mainly three kinds of pollution – air pollution, water pollution, soil pollution.

         Air pollution is caused by the release of harmful gases and particles into the atmosphere, such as carbon monoxide, sulfur dioxide, and particulate matter. This can lead to respiratory problems, heart disease, and other health issues.

          Water pollution is caused by the release of chemicals, pesticides, sewage, and other contaminants into bodies of water, such as rivers, lakes, and oceans. It can harm aquatic life and make water unsafe for human use.

          Soil pollution is the contamination of fresh and fertile soil which adversely affects the health of crops, plants, animals, human beings and other organisms living in it. Addition of variety of unwanted substances and toxic chemicals from many sources to the soil in the odd proportion causes whole land pollution.

                  Pollution is caused by both natural and human activities, such as industrial processes, transportation, and waste disposal. While some pollution is unavoidable, it is important for individuals and governments to take steps to reduce pollution and protect the environment. This can be done through actions such as using environment friendly products, properly disposing of waste, and supporting policies that promote sustainability.

         In conclusion, environmental pollution is a major issue that requires attention and action from individuals, businesses, and governments. By taking steps to reduce pollution and protect the environment, we can ensure a healthier and more sustainable future for ourselves and for generations to come.
