Read the passage carefully and answer the questions following it.
Fish population is in serious danger from global warming. Climate change is increasing the water temperature in rivers, lakes and seas. This means there is less food and oxygen available for fish. It also means the fish may not grow fully and may have fewer offspring. Some fishes will become extinct if temperatures rise even by one or two degrees.
Climate change increases the pressure on fish population. Fishes are one of the world’s most valuable biological assets. Forty percent of people in the world eat fish as their main source of protein. If we fail to reduce greenhouse gas emissions, we will increase the pressures on fish. As a result, people who depend on fish will suffer from hunger and poverty.

বিশ্ব উষ্ণায়নের ফলে মাছের সংখ্যা মারাত্মক হুমকির মুখে। জলবায়ু পরিবর্তনের ফলে নদী, হ্রদ এবং সমুদ্রের পানির তাপমাত্রা বৃদ্ধি পাচ্ছে। এর অর্থ হল মাছের জন্য খাদ্য এবং অক্সিজেনের পরিমাণ কম। এর অর্থ হল মাছ সম্পূর্ণরূপে বৃদ্ধি নাও পেতে পারে এবং কম বংশধরও হতে পারে। তাপমাত্রা এক বা দুই ডিগ্রি বৃদ্ধি পেলে কিছু মাছ বিলুপ্ত হয়ে যাবে।
জলবায়ু পরিবর্তন মাছের সংখ্যার উপর চাপ বৃদ্ধি করে। মাছ বিশ্বের সবচেয়ে মূল্যবান জৈবিক সম্পদগুলির মধ্যে একটি। বিশ্বের চল্লিশ শতাংশ মানুষ প্রোটিনের প্রধান উৎস হিসেবে মাছ খায়। যদি আমরা গ্রিনহাউস গ্যাস নির্গমন কমাতে ব্যর্থ হই, তাহলে আমরা মাছের উপর চাপ বৃদ্ধি করব। ফলস্বরূপ, মাছের উপর নির্ভরশীল লোকেরা ক্ষুধা ও দারিদ্র্যের শিকার হবে।
