Our Earth is the most valuable thing to us because without it, we would have nowhere to live, and without an earth we would not have a home. Since this is the planet we call home, don’t you think we should at least take care of it and everything around it? Well the answer is yes, because if we are not taking care of the earth you are basically not taking care of your own home. Water is the most important thing on the earth because without it, we would not be able to live. The second most important

emissions from animals, agriculture such as rice paddies, and from Arctic seabeds Methane is another extremely potent greenhouse gas, ranking right behind CO2. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in rice paddies, methane is produced. The process also takes place in the intestines of herbivorous animals, and with the increase in the amount of concentrated livestock production, the levels of methane released into the atmosphere is

techniques used are the multiple tube fermentation method, which involves three different media and multiple serial dilutions. (2) The third exercise was the ammonification experiment. Ammonification is the production of ammonia resulting from the decomposition of nitrogen from dead and decaying organic matter or animal wastes. It is an important source of nitrogen for plants and this test is used to determine the presence of ammonifying microbes in a soil

Chapter 1 INTRODUCTION The world population is living, working, vacationing, increasingly mixing along the coasts, and standing on the front row of the greatest, most extraordinary, plastic waste tide ever faced. Washed out on the coasts in obvious and clearly visible form, the plastic pollution display obviously seen on the beaches is only the preface of the greater story that unfolded further away in the world’s oceans, yet mostly originating from where people stand: the land. In 2008, our

Urban Waste Management Solid wastes are those organic and inorganic waste materials produced by various activities of the society, which have lost their value to the first user. Improper disposal of solid wastes pollutes all the vital components of the living environment (i.e., air, land and water) at local and global levels. There has been a significant increase in MSW (municipal solid waste) generation in India in the last few decades. This is largely because of rapid population growth and economic

In 21st century, one of the biggest issues is the problem of global warming, in which the temperature of Earth is rising quickly than ever before, and it is affecting every aspect of life on this planet, from agriculture to animals to humans. It is believed by many, that the advance technology is one of the main reasons why it exists, but the debate never ends on this. Along with that, emission of greenhouse gasses and deforestation are also considered some main reasons for its cause. . Global warming

Introduction Mids-1600s and an English scientist named Robert Hooke made observations. He observed strands of fungi among the specimens of cell his viewed. Robert Hooke in 1665 reported that living things were composed of title boxes or cells. He then devised the compound microscope and illumination system and stated that microbes were a life’s smallest structural units were cells. Then in 1670s, decades after, Dutch merchant named Anton van Leeuwenhoek made careful observations of microscopic organisms

Top of Form Introduction The utilization of resources and generation of waste is for beyond the limit that the biosphere was made to carry. Infact, man today is caught in the vicious circle of increasing wants, declining resources and increasing waste being generated by the industries and municipalities is posing a problem of enormous dimensions. The domestic and industrial effluents are contributing in enhancing this problem. It might become the biggest problem if it is not dealt with immediately
