There’s poison in our food

Image
An ever-increasing population is facing a major problem of availability of safe and acceptable food. Industrial pollution and food processing and packaging is one of the prime causes of poisonous effects of food and foodstuffs. About three –fourths of the human diseases in today’s industrialized world are caused by the environmental pollutants. Foods may be contaminated by substances of synthetic as well as natural origin present in that environment. Contamination of foods may also result from chemical spill or from the process of preparation and packaging of foods as well as certain chemicals added as food additives during food processing. Thus the major hazards from poisonous substances in food comprise: bacterial contamination naturally occurring toxins and chemical carcinogens, accidental chemical contaminants, pesticide contaminants and food additives. Tremendous increases in fertilizers, pesticides, and insecticides etc. for high agriculture yields have badly destroyed food chain...

Digha Marine aquarium and research centre

Image
I visited Digha recently and found that the Marine aquarium and research centre there is one of the best in India , With the one in Mumbai keeping only local fishes in comparrison with the great number of species from all over India and some from abroad , here. I really am pleased to see such beautiful aquarium in Digha. ZSI is supposed to be running this centre and indipets.com is in charge of maintaining the fishes. Some fishes I saw there are as below. Common Name :- Groupers Scientific name:-Epinephelus spp They can be very colorful to almost monochrome according to their species. All Epinephelus are protogynous hermaphrodites .Mostly predatory feeding on live and artificial feeds, likes to stay alone and reproduction is not known to have taken place in captivity can be kept with larger fishes. Common Name :- Red Squirrelfish Scientific name:-Holocentrus ruber Crepuscular lurkers , and not yet known to be breeding in captivity . Feeds on live food but accepts artificial food . Comm...

Development triggers pollution

Nature and mankind form an inseparable part of the life support system which constitutes of five vital elements namely air, water, land, flora and fauna which are all interconnected , inter-related and interdependent and have coevolved and are co-adapted. Since the present-day society largely depends on chemicals, the rapid pace of all round industrialization and modernization of life, there will certainly be more and more instances of a variety of chemical and biological contaminations leading to explosive state of environmental degradation and consequent health hazards. The major environmental problems include long term occurring acid rain, extensive contamination of surface and ground waters, severe air pollution both from automobile and industrial exhausts, uncontrolled hazardous waste sites, long range transport of pesticides and other deadly poisonous chemicals, estuarine and coastal water pollution, global warming because of increasing density of greenhouse gases, accidental rad...

Oil Slick – the redeeming feature

The much maligned oil slick in the Gulf can be a blessing in disguise too. The marine microorganisms feed on hydrocarbons and other components of the oil and register a high growth rate and therefore are a greater source of nourishment for the fish and other aquatic life forms. This may lead to a much greater seafood production than in usual circumstances. It has been observed that the micro-organisms found universally in water columns and water sediments of the ocean are in abundance in the areas of high hydrocarbon concentration, some of these micro-organisms constitute an important link in the food chain and the productivity cycle. Since micro flora are actively oxidizing hydrocarbons in the ocean, oil may be considered as another source of carbon for use in the life cycle of micro flora. Nutrients cycled by bacteria may also improve growth of photo planktons. The best evidence in this regard is that a creel census in the Corpus Christi Bay, off Louisina coast in the USA showed that...
