...structural units were cells. Then in 1670s, decades after, Dutch merchant named Anton van Leeuwenhoek made careful observations of microscopic organisms. Leeuwenhoek’s microscope that was created by him are composed of one lens. On 1674, Leeuwenhoek discovered bacteria, and he called them animalcules. Until his death in 1723, Leeuwenhoek revealed the microscopic world to scientist of the day and is regarded as one of the first to provide accurate descriptions of protozoa, fungi and bacteria. After he died, the microbiology did not develop rapidly because microscopes were rare, but on those years Francesco Redi disputed the theory of spontaneous generation, that microorganism arise from lifeless matter such as beef broth. But in the late 1800s of the development of microbiology, scientists seized the opportunity to further develop the germ theory disease as introduced by Pasteur and proved by Koch. Many microbial disease been discovered during that period leading to the decreasing of human population on that time. After the World War II, antibiotics were introduced to medicine. In the 1940s, electron microscope was developed and perfected and followed by development of vaccine. Then until now, microbes were used into many fields of human beings, including the development of pharmaceutical products, the use of quality controls methods in food and dairy products, the control of disease-causing microorganism in consumable waters, and industrial. Microbes and its properties...

...A major piece of evidence that global warming is a manmade phenomena is that just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities green house gases such as fossil fuel (petrol is carbon based) burn and contribute to the green house gases, which keeps the heat in Global warming is primarily a problem of too much carbon dioxide (CO2) acts as a blanket, trapping heat and warming the planet 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx)-- so this backs up that the fossil fuel is major contributing more than greenhouse gases The emissions of CO2 have been dramatically increased within the last 50 years and are still increasing by almost 3% each year, see graph below: * Carbon dioxide (CO2).

...The System of Rice Intensification (SRI) in Bhutan: A feasibility study of a new rice farming system with special reference to location specific trials and yield performance of different varieties Karma Lhendup Sherubtse College, Royal University of Bhutan, Email: lhenkarma@yahoo.com 1. Introduction Rice is one of the most important staple food crops for the people of Bhutan. Different varieties of rice, both local and introduced, are cultivated in a wide range of elevations, from subtropical lowlands (150 m) in the south up to elevations as high as 2600 masl in the north (Table 1). The present productivity of rice, less than 3 t/ha, cultivated on 46,585 acres out of the 69,414 acres of irrigated land has not been able to attain food sufficiency level in the country (MoA, 2004). The constant land degradation plus expansion of development activities taking place on the extremely limited area of arable land for agriculture (7.8% of the total land area of 39,911 km2) has detracted from cultivable land for rice, and productivity is constrained by a lack of farmer education on rice planting and rice ecosystems, further complicating achievement of the country’s goal of food security for all. As a result, a huge amount of rice is imported from India to meet the increasing food demand in the country, with population growth still increasing by 3.1% per annum (http://www.fao.org/ag/agl/aglw/aquastat/countries/bhutan/print1.stm). The prevalence of small-scale and marginal farms, with...

...Don't discard banana peels; they are valuable as plant fertilizer. Bananas are packed with nutrients, and that includes their peels. Though you won't want to eat them yourself, your plants benefit from the nutrients as the peels decay. Plants need nutrients need to thrive. Nitrogen, phosphorus and potassium are required in the highest amounts, and nutrients such as calcium, manganese, sodium and sulfur are necessary in lower amounts. While various levels of these nutrients occur naturally, some soils can use a boost. Adding banana peels around prized plants is a widespread gardening practice that can improve your soil.

...INTRODUCTION TO SANITATION Sanitation is the hygienic means of promoting health through prevention of human contact with the hazards of wastes as well as the treatment and proper disposal of sewage or wastewater. Hazards can be either physical, microbiological, biological or chemical agents of disease. Wastes that can cause health problems include human and animal excreta, solid wastes, domestic wastewater (sewage, sullage, greywater), industrial wastes and agricultural wastes. Hygienic means of prevention can be by using engineering solutions (e.g., sanitary sewers, sewage treatment, surface runoff management, solid waste management, excreta management), simple technologies (e.g., pit latrines, dry toilets, urine-diverting dry toilets, septic tanks), or even simply by personal hygiene practices (e.g., hand washing with soap, behavior change). Providing sanitation to people requires a systems approach, rather than only focussing on the toilet or wastewater treatment plant itself. The experience of the user, waste collection methods, transportation or conveyance of waste, waste treatment, and reuse or disposal all need to be thoroughly considered. DEFINATION OF SANITATION The World Health Organization explains sanitation as follows: "Sanitation generally refers to the provision of facilities and services for the safe disposal of human urine and feces. The word 'sanitation' also refers to the maintenance of hygienic conditions, through services such as garbage...

...The Greenhouse Effect Ashley 24/1/2013 The Greenhouse effect is a process that is naturally occurring on our planet. The reason it is a concern is many scientists believe the process is being changed because of our use of energy in the last 100 years or so. Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter. The earth's atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the earth's atmosphere, passing through the blanket of greenhouse gases. The greenhouse effect works in the following manner (i) Energy from the sun passes though the earth's atmosphere in the form of visible light (sun light). (ii) Some of the sun's energy turns to heat and warms the earth's air and land. (iii) The rest of the sun's energy becomes infrared radiation and is re-emitted into the atmosphere. (iv) Greenhouse gases in the atmosphere trap some of this infrared radiation and bounce it back to the earth again, warming the planet even more. Greenhouse Gases Carbon dioxide It is considered the most predominant anthropogenic greenhouse gas, as 60% of the anthropogenic...

...Cannabis/Marijuana for Our Environment, Health and Ecology A Research Paper in English Submitted to: Mrs. Ma. Leonor M. Vertucio Submitted by: Mayuga, John Angel Ocino, Angel Joseph I. Introduction Our topic is about Cannabis, also known as marijuana (sometimes spelled "marihuana") among many other names, refers to any number of preparations of the Cannabis plant intended for use as a psychoactive drug or for medicinal purposes. According to the United Nations, cannabis "is the most widely used illicit substance in the world.“ The typical herbal form of cannabis consists of the flowers and subtending leaves and stalks of mature pistil late female plants. The resinous form of the drug is known as hashish (or merely as 'hash') The major psychoactive chemical compound in cannabis is Δ9- tetrahydrocannabinol (commonly abbreviated as THC). Cannabis contains more than 400 different chemical compounds, including at least 66 other cannabinoids (cannabidiol (CBD), cannabinol (CBN) and tetrahydro cannabis varin (THCV), etc. which can result in different effects from those of THC alone. In modern times, the drug has been used for recreational, religious or spiritual, and medicinal purposes. We choose this topic to know and to inform our listeners that marijuana is a harmful plant...

...Establish and Manage Your Home Lawn The home lawn and turf areas surrounding churches, parks, and office buildings do more than just serve as pleasant green backdrops. The grass plants that make up the lawns serve as miniature air-conditioners and pollution-abatement centers. On a block of eight houses, the front lawns have the cooling effect of 70 tons of air-conditioning. The plants, in transpiring water to cool themselves, also cool the surrounding area. Roughly 50 percent of the heat striking a turf area is eliminated by transpiration. When the temperature of the sidewalk is 100 °F, the temperature of the adjacent turf remains near 75 °F. This cooling may last into the night, with studies showing a 13-degree cooling at 9 p.m. This air-conditioning is not free, however. An average 5,000-square-foot lawn transpires about 3,000 gallons of water on a hot summer day. If this water is not supplied by rain, it must be applied by some other means. Turfgrass also functions as a noise barrier. Studies at the Riverbank Acoustical Laboratory in Geneva, Illinois, found Kentucky bluegrass turf more sound-absorbent than a heavy carpet on a felt pad. One of the most significant byproducts of a living, green backdrop is its effect upon the atmosphere. A 250-square-foot lawn produces enough oxygen for a family of four. The average lawn traps significant amounts of carbon dioxide, peroxyacetyl nitrates, and ozone, as well as particulate matter. A most important effect is the prevention of soil...
