The world’s oceans are becoming acidic at an “unprecedented rate” and may be souring more rapidly than at any time in the past 300 million years.
In their strongest statement yet on this issue, scientists say acidification could increase by 170% by 2100.
They say that some 30% of ocean species are unlikely to survive in these conditions.
The researchers conclude that human emissions of CO2 are clearly to blame.
The study will be presented Read more

Warmer temperature prompts trees to release aerosols which in turn stimulate cloud formation. And that can help to cool the temperature, at least modestly.
Trees may provide the Earth with a little shade from global warming – indirectly. European and Canadian researchers report that they have found what engineers like to call a negative feedback loop above the forests of Europe and North America.
It works like this. Trees – those natural chemical factories that routinely deliver complex aromatic compounds such as Read more

Biodiversity contributes considerably to economy and environment
Dr. M. A. BASHAR
In developing countries, the necessity of publicising services of forests is severely lacking. This sector must be given attention with special emphasis. The country like Bangladesh has to be very serious in all respects to understand and exercise the services offered by the forests. We must remember that the services are very important Read more

Doha Climate Conference
What the outcome yields for Bangladesh?
Md. Mahfujur Rahman
Thirty-seven industrialized countries had been accused of releasing Greenhouse gases in Kyoto Protocol under United Nations Framework Convention on Climate Change (UNFCCC). Signatory members to the UNFCCC have been meeting annually in Conference of the Parties (COP) to assess progress in dealing with climate change since 1994. This year Climate leaders from all over the world gathered at Doha from 26 November to 8 December 2012 to find ‘what to dos’ for reversing the grim effect of global Read more

Though Bangladesh is prominently a plain land, its Chittagong, Cox’s Bazar, Rangamati, Khagrachhari, Bandarban and Sylhet have hilly areas with forests and rich biodiversity. These areas are full of natural resources fulfilling needs of the people and other living species.
But at present, the destruction of hills in every area has become so alarming that many concerned people have been upbeat against the greedy grabbers who are out to convert these hilly areas into plain lands to set up industries and Read more

Natural Resource Governance
A prerequisite for sustainable development
The constitution of Bangladesh — article 143– illustrates that all natural resources on land and underground minerals and other things of value underlying the ocean within the territorial waters, or the ocean over the continental shelf of Bangladesh, are the properties of Bangladesh. In general, natural resources include oil and gas, minerals and metals, forests, fish, land and water. In Bangladesh, some 83% of the total population explicitly depends on natural resources. Therefore, to ensure sustainable use of these resources Read more

Contemplating mitigation measures
Md. Atikur Rahman
All things that make up the environment are interrelated. The way in which people, animals and plants are related to each other and to their surrounding is known as
ecology. The ecosystem is a complex web that links animals, plants and every other life form in the biosphere. By altering any one part of the web you can affect all
other parts. For example, the destruction of forests may have serious ecological consequences for humans and animals Read more

Over the recent years, Savar is experiencing immense pressure of new industrial, commercial and residential establishments. But most of these have already been done or
are underway indiscriminately haphazardly, and by violating the environmental laws and ignoring overall public convenience, not to speak of the care for future growth.
It has been a lucrative Read more

Sonadia Island is one of the biodiversity hotspot of Bangladesh. In 1995, the Government of Bangladesh included a provision for the declaration of Ecologically Critical Area (ECA) in the Bangladesh Environment Conservation Act. Twelve sites are classified as ECAs and guidelines exist to control further damage to these areas. Sonadia is considered ecologically important by the government and in 1999 was declared as an ECA under Environmental Act of Read more

It is learnt from newspapers very recently that in the Sundarbans area three large constructions will take place which are very dangerous and detrimental to normal functioning of the mangrove forest ecosystem. It means that the interactions between biotic and abiotic factors will be seriously hampered in the ecosystems conservation. The projects are: construction of coal-based electric plant; depot for storage of coal in Phulbari; and a ship-yard covering large area. Already it is protested by various environment related Read more

Legal response to loss and damage
Hafijul Islam Khan
The adverse impacts of climate change have continued to devastate the lives and livelihoods of millions of people and inflict large economic losses. According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, there has been a global increase in weather related disasters between 1980 and 2003. The report estimated that during that period the economic loss due to damage caused by natural disasters is one trillion USD in total. Moreover, the UN Office for the Coordination of Humanitarian Affairs has estimated that in 2008 over Read more

Global Warming and Over-Exploitation
Corals of St.Martin’s at stake
Dr. Anisuzzaman Khan
Honey comb corals around Saint Martin’s island are under stress due to coral bleaching. While the COP 17 — UN climate convention — was being held in Durban of South Africa, a Nature Watch Team (NWT) of Ekattor Television watched that a noticeable coral bleaching was defacing the corals of Saint Martin’s island of Bangladesh due to global warming. A four-member Scuba diving team moved under water around Saint Martin’s during the last week of December, 2011. They observed that the honey comb corals on the east coast of the island are severely affected by Read more

GLOBAL food demand will double by 2050, according to a new projection, and the farming techniques used to meet that unprecedented demand will significantly determine how severe the impact is on the environment, researchers say.
The study researchers warn that meeting the demand for food will clear more land, increase nitrogen use and significantly add to carbon dioxide and other greenhouse gas emissions. These actions could harm the atmosphere and cause the extinction of numerous species, Read more

Increasing threats to life
Mohammad Tareq Hasan
With a population of over 15 million Dhaka is one of the most congested cities of the world. This rapidly growing city is located on the northern bank of the river Buriganga and surrounded by other rivers, namely, the Turag to the west, the Tongi Khal to the north and the Balu to the east. The rivers surrounding Dhaka are an advantage to it and essential for the survival of the mega city as these provide drainage system, drinking water, different kinds of fishes and also waterways for traveling. However, being the capital of Bangladesh Read more
