Evolution of fisheries sector in BangladeshMD. ZANE ALAM
Bangladesh is a densely populated country of 147 570 km2 with a population of 160
million people. It is fortunate in having an extensive water resource in the form of ponds,
natural depressions (haors and beels ), lakes, canals, rivers and estuaries covering an area
of 47,03,658 ha .
The present per capita annual fish consumption in Bangladesh stands at about 14 kg/year
against a recommended minimum requirement of 18 kg/year; hence, there is still need to
improve fish consumption in the country.
Fisheries in Bangladesh are diverse, there are about 795 native species of fish and shrimp
in the fresh and marine waters of Bangladesh and 12 exotic species that have been
introduced. In addition, there are 10 species of pearl bearing bivalves, 12 species of
edible tortoise and turtle, 15 species of crab and 3 species of lobster.
The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations.

HEAVY METAL POLLUTION AND REMEDIATION IN URBAN AND PERI-URBAN AGRICULTURE SOILSchikslarry
Throughout the world, there is a long tradition of farming intensively within and at the edge of cities (Smit et al., 1996). However, most of these peri-urban lands are contaminated with pollutants including heavy metals, such as Cu, Zn, Pb, Cd, Ni, and Hg. The major sources of heavy metal contamination in agricultural soils are discharge of effluents from domestic sources, coal-burning power plants, non-ferrous metal smelters, iron and steel plants, dumping of sewage sludge and metal chelates from different industries. Once the heavy metals are released into soils, plants can absorb and bio-accumulate these heavy metals and thereby affect humans and animals’ health upon consumption (Seghal et al., 2014). Hence, there is a great need to develop effective technologies for sustainable management and remediation of the contaminated soils. There are conventionally physicochemical soil remediation engineering techniques, such as soil washing, incineration, solidification, vapour extraction, thermal desorption, but they destroy the plant productive properties of soils. Moreover, they are usually extremely expensive, limiting their extensive application, particularly in developing countries and for remediation of agricultural soils (Kokyo et al., 2014). Phytoremediation has been increasingly receiving attentions over the recent decades, as an emerging, affordable and eco-friendly approach that utilizes the natural properties of plants to remediate contaminated soils (Wang et al., 2003). Phytoremediation includes phytovolatilization, phytostabilization, and phytoextraction using hyper-accumulator species or a chelate-enhancement strategy. The future of this technique is still mainly in the research phase, and many different Hyperaccumulators and crops that can be cultivated in heavy metal contaminated are still being tested.
Coastal aquaculture is having an adverse impact on the environment due to intensive shrimp culture. several other factors are also getting affected due to intensive coastal aquaculture.

Introduction The whale shark ,Rhincodon typus are large slow moving filter – feeders that are the largest known living fish in the ocean .
The whale shark has a very widespread distribution and occurs throughout the worlds tropical and warm temperate seas.
The largest confirmed Individual had a length of 18.8 m.
Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
