The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
[9] [10] According to the State of Global Air report in 2021, at last 236,000 people died due to air pollution in Bangladesh. [11] According to a World Bank study, air pollution is responsible for 20 percent of premature deaths in Bangladesh.

Forests harbour most of Earth's terrestrial biodiversity. The conservation of the world's biodiversity is thus utterly dependent on the way in which we interact with and use the world's forests. [78] A new method used in 2011, put the total number of species on Earth at 8.7 million, of which 2.1 million were estimated to live in the ocean. [79]

The agreement covers all ecosystems, species, and genetic resources. It links traditional conservation efforts to the economic goal of using biological ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
Ganges River Delta, Bangladesh and India Population density and height above sea level in Bangladesh (2010). Bangladesh is especially vulnerable to sea level rise. The rivers of Bangladesh mark both the physiography of the nation and the life of the people. About 700 in number, these rivers generally flow south.
Bangladesh is known for its vulnerability to climate change and more specifically to natural disasters. It is important to mention the fact that the location of the country is vulnerable for the presence for three powerful rivers, Asian rivers, Brahmaputra, Ganges and the Meghna along with their numerous tributaries that could result massive floods.
The Geology of Bangladesh is affected by the country's location, as Bangladesh is mainly a riverine country. It is the eastern two-thirds of the Ganges and Brahmaputra river delta plain stretching to the north from the Bay of Bengal .
