গরম বাড়ছে কেন?

 


গরমের প্রধান কারণ হলো পৃথিবীর মাধ্যমে আবহাওয়া ও জৈব প্রক্রিয়ার সংক্রমণ। গ্লোবাল ওয়ার্মিং বা বিশ্বব্যাপী উষ্ণতা বা তাপগতীয় উষ্ণতা একটি প্রধান কারণ। গ্লোবাল ওয়ার্মিং মানে হলো মানুষের কারণে পৃথিবীর গভীর বায়ুমণ্ডলে কার্বন ডাইঅক্সাইড (CO2) এবং অন্যান্য গ্রীনহাউস গ্যাসের পরিমাণ বেড়ে যাওয়ার ফলে পৃথিবীর তাপমাত্রা বেড়ে আসছে। এই গ্রীনহাউস গ্যাস দ্বারা উষ্ণতা পৃথিবীর সামান্য পর্যায়ে রেখে যাওয়া থেকে পর্যায়ের তাপমাত্রা বেড়ে আসছে এবং জলবায়ু চক্র সম্পাদন হয়ে আসছে। এর ফলে জলের উষ্ণতা বেড়ে আসে, যার ফলে আন্তর্জালিক উষ্ণতা ও প্রাকৃতিক উষ্ণতার সাথে মিশে যায়।

Which came first Egg or Chicken?

  The question of whether the chicken or the egg came first is an age-old philosophical conundrum. From a biological perspective, the egg came first. Eggs have been around for millions of years, long before chickens as we know them today existed. Animals that predated chickens, such as reptiles and dinosaurs, were laying eggs long before the evolution of birds. Over time, through a process of gradual changes and genetic mutations, a bird species similar to what we now consider a chicken would have emerged from its non-chicken ancestors. This evolutionary transition would have occurred through the accumulation of genetic changes in successive generations. Eventually, a bird hatched from an egg would have possessed the genetic makeup that classifies it as a chicken, marking the point where the first chicken emerged. Therefore, the first chicken would have come from an egg laid by its non-chicken ancestors. In this sense, the egg came before the chicken in the evolutionary timeline.
