The use of anti-biotics in the aquaculture industry has been widespread and beneficial- but it has now progressed to overuse. Injudicious use of antibiotics in aquatic animals has led to antibiotic resistance. This was specially felt in the shrimp culture industry, where massive increase in production, massive overcrowding and unrestricted use of antibiotics led to emergence of anti-biotic resistant bacteria. This has, in turn, led to production crashes and losses to farmers engaged in aquaculture.
एके काळी भारताला “सोने कि चिडिया ” म्हटले जाई. असा आपला गौरवाने उल्लेख केला जात असे कारण भारत आधी पासून कृषी प्रधान प्रदेश आहे. संपन्नतेचे, ऐश्वर्याचे प्रतीक म्हणजे सोने. भारतातील संपूर्ण शेती पद्धती वैदिक (नैसर्गिक) ज्ञानाचा वापर करून हवामानाच्या शक्यतांचा अभ्यास करून, आणि देशी बियाणांचा वापर करीत पर्यावरण संतुलित राहील अशा पद्धतीने केली जात होती. परंतु दिवसेंदिवस वाढणाऱ्या लोकसंख्येला लागणाऱ्या अन्नामुळे देशामध्ये अन्नधान्याची समस्या उभी राहिली त्यामुळे हरित क्रांती (१९६७ – १९७८ ) मुळे दरडोई उत्पादकता वाढवण्यात आली आणि हायब्रीड -संकरित बियाणे जन्माला आले आणि सिंचनाच्या सोयी यामधून शेतीची क्रांती झाली. परंतु हायब्रीड बियाण्यांमुळे कीटकनाशकांची गरज आणि रासायनिक खतांची गरज जास्त पडू लागली. औषधांच्या आणि रासायानांच्या अती वापरामुळे पर्यावरणाचे संतुलन बिघडले. जमिनीतील सूक्ष्म-जैविक घटकांचा नाश झाल्याने जमिनी नापीक होऊ लागल्या. पर्यायाने खतांची कार्यक्षमता कमी झाली. या जमिनींच्या कमी कार्यक्षमतेमुळे रासायनिक खतांचा पुन्हा वापर खूपच वाढला आणि ह्या अश्या चक्रव्यूहात अजूनपण अधुनिक शेती अडकलेली आहे.
The general awareness regarding microbes has greatly increased over the past few decades. However, little is known about their distant cousins, ‘Protozoans and Metazoans’, more popularly known as ‘higher life forms’. Both these categories of organisms are of great value to industrial effluent treatment. Microorganisms constitute 95% of population in an ideal activated sludge ,of which 4 % of this microbial population consist of higher life forms. Although these higher life forms contribute very little to the removal of organic nutrients, their presence however greatly enhances the clarity of the water and provides an indication of effluent condition (Eg. Toxicity,organic load, dissolved oxygen etc.).
Mumbai is the city of glitz and glamor; of highrises and plush hotels and housing complexes, of bars and exotic restaurants, of soaring real estate values, of gilded star homes at Bandra and Juhu, of swanky cars and malls and international brands etc. But underneath all that jazz, Mumbai grapples with a giant problem- waste management. The city’s faring poorly when it comes to handling proper, hygienic disposal of human and kitchen refuse. Any number of factors might be responsible for this.
It seems like the Trump administration is eager on undoing every policy put in place by the Obama administration, in this case, for the worse.
No, this is not the suspense-filled title of a crime novel. It’s a blog post, talking about an actual event that has happened this year, regarding environmentalists and the work that they do. This is about the Goldman Environmental Prize, and the events surrounding it.
Gender: Represents the social relationships between men and women, where power disparities play an important role.
Manual scavenging, in India, is a practice as unhygienic as it is disgusting and indignifying. It has also, for long, been a tool of caste oppression- certain castes like the Valmikis have been practising it historically.
“When one tugs at a single thing in nature, he finds it attached to the rest of the world”
We often wonder of the world beyond our skies, heavenly bodies and extra terrestrial life; but we seldom stop and think of the bountiful universe beneath our feet. We have this universe to thank, for the food we eat, the clean air we breathe, quite literally for our very existence. Along with organic matter, decaying material and inorganic components of the soil, are present billions of lively microbes that are responsible for the continuos replenishment of our soils.
The United States has always been a world leader, not just because of its superpower status or wealth or military or industrial might, but also because it leads in scientific innovation, civil liberties, women empowerment and issues like climate change.
