Nature and We are

 

When we see the today’s summer it’s totally different from the summer’s in childhood. Nowadays we are feeling unbearable heat in summer that has happened to our world. What are the reasons behind this? Today I’m going to shed light on the numerous causes that are posed by us. The sixty percentage land of Bangladesh is situated above the five meters from sea level. From this we can easily surmise how vulnerable our country is! Any types of flood or natural disaster affects us very badly. Headly centre for climate prediction and research projected that the sea level height will increase 40 centimetres within 2080.General circulation model shows that within 2100 Bangladesh temperature will be increased by 2.5℃. This temperature will badly effect on our economy and other sectors in our country. From the Industrial period to today global temperature has raised to approximately 1.5℃ according to NASA. Today we are using lots of CFC based machine which are dangerous for Ozone layer. The ultra violet ray from Sun can easily penetrate through cracked Ozone layer that caused a serious effect on our global warming. Moreover Many of Industries are increasing day by day transgressing climate safety and regulation. Detrimental substances and harmful gas overwhelmingly spread in our nature. The Artic and the Antarctic region begins to start melting their iceberg which will definitely spill a huge amount of water in our ocean. That could have responsible to happen numerous disaster over the future century. There aren’t only iceberg melting problem but also the permafrost warning. Permafrost in Alaska, Canada, and Siberia have started to melt. It will release a large amount of greenhouse gas. Permafrost contains rock, soil, sand and pockets of pure ground ice that is totally riches in carbon. Around 1500 billion tonnes of carbon are holding by this permafrost alone which is twice as much as in atmosphere. So in upcoming years Bangladesh will fall in great difficulties with Natural disasters.
