As a result of continuous deforestation, the biodiversity of Bangladesh is under threat today. The Royal Bengal Tiger of the Sundarbans, the Chitra deer is almost extinct. Thousands of species of animals and aquatic animals are being lost in Bengal. In the meantime, more than 100 of the 5,000 species of trees are almost extinct. Out of 632 species of birds, 12 species are already extinct and 30 species are on the verge of extinction. Of the 110 animal species, 40 do not exist. Of the 60 species of fish, 54 do not exist. It is feared that by 2020, agricultural production may fall by 30 percent. Twenty-two percent of South Asia's agricultural land could be destroyed.
What the tree gives us
What a tree gives us in a year is the equivalent of 10 air conditioners producing heat, absorbing 650 gallons of rainwater and absorbing more than 60 pounds of harmful gases from the air. 1 gram of water evaporates 560 calories of solar energy. 1 large tree releases 100 gallons of water a day. From 1 hectare of green land, the plant receives an average of 900 kg of carbon-di-oxide per day and gives 750 kg of oxygen during photosynthesis. 1 medium sized mango tree produces oxygen worth Rs 14 lakh in 40 years. Having 5 hectares of forest reduces the temperature of the area by 3-4 degrees, prevents soil erosion and increases humidity in the air. Trees absorb 85-90% of noise, protect us from noise pollution.
To burn 1 lakh bricks, 2500 tons of fuel wood is required. Our country needs about 108 crore mana of fuel wood for cooking every year. According to the survey, Finland has 84%, Myanmar 64%, Japan 63%, Sweden 55%, Canada 45%, United States 34% and India 20% and Bangladesh only 09% and 18% of the forest. But it is necessary to have at least 25% forest land. A healthy person needs to eat about 250 grams of vegetables and 115 grams of fruits daily. In Bangladesh we are able to eat 40-45 grams of fruit per head. In general, 40 percent of human brain development occurs in the womb and the remaining 80 percent develops within 5 years of birth. Due to lack of vitamin A, about 30-40 thousand children suffer from night blindness every year. However, fruit trees have a huge contribution to provide nutrition and increase immunity.
Not only on Bangladesh 🇧🇩 probably worldwide this is happening which is quite disappointing in my opinion 😠😤
