Mammals, are the most intelligent vertebrates, which have well-adapted over the last millennia, distributing over and very successfully inhabiting almost all the habitats of the world, ranging from the Arctic to the Antarctic region. This highly developed chordate have traversed the land, water and sky, inhabiting anywhere of these biomes from the trees to the ocean.
The commonly known Meni or Bheda fish in Bangladesh, Nandus nandus (Ham.-Buch.), is an important fish-food of high nutritive value in South Asian countries. The natural population of this fish has been declining rapidly due to some parasitic infections, which has escalated due to the lack of scientific management, anthropogenic disturbances, unhabitable water quality, and such related factors.
There are 10 Species of non-human primates (here after primates) in Bangladesh – one Species of Loris, five Macaques, three Langurs and one lesser Ape (Brandon-Jones et al.2004; IUCN Bangladesh 2015). Primates are the most threatened group of mammals in the country; 90% of them are threatened.
Rivers are the key point of natural resources, integrated with the culture and civilization of related people. Early civilizations like in ancient Egypt (River Nile), Mesopotamia (River Tigris–Euphrates), ancient China (River Yellow and Yangtze) and Indus valley (River Indus) still bears the sign of social system – a history of mankind. In Indian sub-continent, the Indus valley civilizations namely Harappa and Mohenjo-Daro are noted for their ancient cultural ramifications and urban designs.
Municipal Solid Waste Management (MSWM) is one of the main environmental problems in Dhaka, the capital city of Bangladesh. About 5000 tons of waste is being generated in Dhaka city every day among which only about more than half portion is properly collected and dumped. So, a huge amount of waste is being mistreated every day. In the present study an effort was made to represent the current waste management (WM) scenario of Dhaka city, how Dhaka City Corporation (DCC) is trying to cope with the WM problem, public concern about some WM practices, the problems created by improper WM system and some possible solutions to the WM problems.
The Black Cumin (Nigella sativa) has been used as traditional medicine for centuries. The crude oil and thymoquinone (TQ) extracted from its seeds and oil is effective against many diseases like cancer, cardiovascular complications, diabetes, asthma, kidney disease etc. It is effective against cancer in blood system, lung, kidney, liver, prostate, breast, cervix, skin with much safety. The molecular mechanisms behind its anticancer role is still not clearly understood, however, some studies showed that TQ has antioxidant role, and it improves body’s defense system; induces apoptosis and controls Akt pathway.
The importance and value of ecosystem goods and services are now widely acknowledged for its positive role in planet, people, and prosperity – three main pillars of sustainable development. The implication has been linked to policy and decision making as an innovative strategy for the improved management of land, water, and living resources that can promote conservation and at the same time fostering human well-being.
The Environmental stability of human settlement now is an international concern; but since the Industrial Revolution in 1760 to the recent past, people have thought about the economic growth in almost all development strategies and programs. They exposed little concern about the environment that could be affected by taking such strategies and programs. That’s why the people have indiscriminately deforested and subsequently industrialized and modernized their habitations. Consequently, the level of greenhouse gases like, Carbon Di-oxide, Carbon Monoxide, Sulphur Di-oxide, Sulphur Monoxide, etc. have increased considerably.
Environmental governance is a concept in political ecology or environmental policy related to identifying the elements needed to achieve sustainability and resilience. It is entwined with different aspects of sustainable development and is crucial not only to the well-being of the people but also for their very survival, particularly for those who depend on natural resources and the environment to manage livelihood.
Human activities in the name of development emit about 29 billion tons of Carbon Di-oxide per year, while volcanoes emit between 0.2-0.3 billion tons. At present, half of the CO2 released from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and marine water. CO2is the primary greenhouse gas emitted through human activities. CO2 is naturally present in the atmosphere as part of the Earth’s Carbon cycle (natural circulation of Carbon is in the atmosphere, oceans, soil, plants, and animals).
Green economy is the Economics of the world concerning work, human needs, the Earth’s materials, and how they mesh most harmoniously with each other. It is primarily about the “usage-value” and not the “exchange-value”; about the quality and not the quantity; about the regeneration of populations, communities, and ecosystems and not about the accumulation of money or materials.
The main focus of the present issue is “Blue Economy”, the economy of marine life, though some articles relate with other environmental issues. It is our pleasure to introduce the...
