For the past few centuries Earth has been witnessing several environmental problems even-though the ongoing climate change events such as increasing temperature, cloud bursts, frequent cyclones, long and irregular winters and drought have received more attention in the public platforms. These extreme climatic events have challenged the physical, mental and economic health of humans and made them to think and speak out. This realisation has been following by several agencies making efforts to mitigate the climate change impacts. It is known that global warming is the result of the incessant release of greenhouse gases especially carbon dioxide (CO₂) from several sectors especially from automobile and associated industries triggering the extreme climatic events. Earlier the natural forests cover and oceans absorbed the enormous quantities of CO₂ released in the environment. However, continuous deforestation and other anthropogenic pressures prevailing in and around the ocean and forest have slowed down the carbon sequestration potential of these systems. Natural forests evolve due to the constant interplay of inter and intra species alongwith unique environmental conditions and play an important role in mitigating the greenhouse gases to a large extent, also acting as oxygen factories. However, in comparison, tropical and savannah forests produce a more oxygen than other forests. Studies have established that the natural regeneration potential of the forest has been decreasing due to continuous deforestation. Ecologists opine that the restoration of natural forests is the ideal way to overcome the global warming impacts. However, restoration of natural forest is a herculean task and almost impossible. The diminishing forest cover affects the life-forms and also carbon storage and oxygen production which might speed-up the global warming process, and so researchers and policymakers encourage afforestation programmes in order to mitigate the global warming.

खालील कुठल्या प्रकारची वनक्षेत्रे तुलनेने अधिक प्रमाणात प्राणवायू/ऑक्सीजन निर्मिती करतात ? Among the following which type of forest contribute comparatively more production of oxygen ?

(a)उष्णकटिबंधीय जंगले/वने / Tropical Forests

(b)सावाना गव्हाळ वने / Savannah Grassland

(c)पर्वतीय जंगले/वने / Mountain Forests

(d)समशीतोष्ण जंगले/वने / Temperate Forests

1)फक्त (a) व (b) / Only (a) and (b)✓ Correct
2)फक्त (b) व (c) / Only (b) and (c)
3)फक्त (c) व (d) / Only (c) and (d)
4)फक्त (b) व (d) / Only (b) and (d)

Tropical forests (Amazon, etc.) due to dense vegetation and Savannah grasslands through extensive photosynthetic biomass production contribute the highest oxygen to the atmosphere.

अमेंझॉन जंगला विषयी योग्य विधान शोधा. Find the correct statements about Amazon forests.

(a)हे एक उष्णकटिबंधीय पावसाळी जंगले आहे. / It is tropical rain forest.

(b)या जंगलाच्या पूर्वेस अटलांटिक समुद्र आहे. / It has Atlantic Ocean at its east side.

(c)या जंगलांनी इक्वेडोरचा 40% भाग व्यापला आहे. / It occupies 40% of Ecuador's total area.

(d)ह्या जंगलात मकाऊ, ट्यूकन्स आणि ब्लॅक स्कीमर्स आहेत. / It is home of Macaws, Toucans and Black Skimmers.

1)(a), (b), (c), (d)
2)(a), (b), (c)
3)(a), (d)
4)(a), (b), (d)✓ Correct

Amazon rainforests are tropical rainforests bounded by the Atlantic Ocean to the east, and are home to diverse endemic wildlife like Macaws, Toucans, and Black Skimmers. Ecuador covers a very small percentage of the Amazon basin, not 40%.

खालील विधाने पहा : / Observe the following statements :

(a)अ. घातक कचरा मृदेमध्ये टाकल्यामुळे जैवविविधता कमी होते. / A. There is loss of bio-diversity due to dumping of toxic waste into soil.

(b)ब. नद्यामध्ये वारंवार पूर येण्यामागे वृक्षतोड कारणीभूत आहे. / B. Deforestation is responsible for frequent floods in river.

(c)क. फ्रांसिस्को मेंडझा यांच्या ऊर्जा क्षेत्रातील कार्यामुळे त्यांना 'अॅमेझॉन गांधी' म्हणून संबोधतात. / C. Fransisco Mendez was known as 'Amazon Gandhi' due to his work in energy field.

1)(1) फक्त विधान क बरोबर आहे / (1) Only statement C is correct
2)(2) फक्त विधान अ बरोबर आहे / (2) Only statement A is correct
3)(3) फक्त विधान अ आणि ब बरोबर आहे / (3) Only statement A and B are correct✓ Correct
4)(4) विधान अ, ब आणि क बरोबर आहे / (4) Statement A, B and C are correct

Dumping toxic waste reduces soil biodiversity, and deforestation causes increased surface runoff leading to frequent river floods. Francisco Mendez (Chico Mendes) was an environmentalist, not an energy expert, associated with the Amazon rainforest.
