Humans Are Responsible For Global Warming - 877 Words

It is not surprising to read on the internet about ice caps melting and strong storms devastating cities. Global warming is a serious issue that should be put in consideration. However, before trying to fix such issue. We should focus on what is causing global warming. Humans are responsible for global warming. Even though, most of the earth’s population deny being responsible for global contamination/global warming. A slight change on temperature can cause a big change on the earth’s weather and environment (i.e. ice caps melting or long droughts in California). According to Pete Spotts in Climate Change: Scientists Now 95 Percent Certain We Are Mostly to Blame, â€Å"Since 1951, Earth s climate has warmed by about 0.6 degrees Celsius, and researchers assessing †¦ the Intergovernmental Panel on Climate Change (IPCC) are 95 percent certain that more than half of the warming is due to human emissions of greenhouse gases.† (Par 1). After the industrial revolution, humans have been using fossil fuels as combustibles (i.e. coal, fuel oil or gas). These gases are very heavy and difficult to vanish in the atmosphere. It means that every time we consume fossil fuels; we expel enormous quantities of toxic gases that help create a phenomenon called greenhouse effect. This phenomenon causes the earth to heat up. As a consequence, the ice caps melt while increasing the sea level. This cou ld end up in massive floods in every coast around the world.

Farm Tools Free Essays

Agriculture has been in the limelight for several decades, it started in different countries across the globe each country in their own time. However, agriculture could not have been achieved without the use of farm tools and machinery. This farm equipment makes it easy for farm activities to be undertaken with an ease. We will write a custom essay sample on Farm Tools or any similar topic only for you Order Now Before the introduction of this equipment, agriculture was difficult and it was only done in small scale. Therefore, the agricultural produce which was produced as a result was only used for consumption purposes. However, with this machinery, there is a large production which is able to sustain consumption and also used for commercial purposes. The world depends largely on agricultural production therefore, farm tools should be embraced across the globe. First, combine harvester is one of the farm tools and it is one of the machines which combine several activities such as harvesting and threshing among others. This equipment was introduced in the year 1935 but it was first used for commercial purpose in the year 1939 (Kataoka). As the word combine suggests, combine harvester is used for several activities such as reaping. The second activity is threshing after the crops have been cut and collected the next activating is to separate the grain from corn. The other activity done by the combine harvester is grain separation, this activity is whereby the grain is separated from the husks. The last activity is cleaning whereby the grain is cleaned by blowing the chaff away. Second, the other farm tool is a mower, this tool is used for cutting grass. The tool is also known as a lawnmower. According to Kataoka, there are the different model of lawn mowers such as solar-powered lawn mower and this type is environmentally friendly. The other model of lawn mower is the automatic lawn mower, this type automatically detects the area of grass to be mowed and the height of grass as required. The other model is gas powered lawn mower and this model is not environmentally friendly since it emits gas into the environment. Lawnmowers are classified based on different factors such as the axis of rotation of the blades. For example, rotary lawn mower in which its axis is vertical and reel lawn mower in which its axis is horizontal. Third, a plough is another farm tool and it is used to till the land so as to aerate the soil for planting purposes. There are different types of ploughs depending on the function they perform. For example, furrow reversible plough which is useful in dry trashy stumpy and hard land condition. The tool is mounted directly on a tractor and it is hydraulically operated. It has two mouldboard ploughs mounted back to back whereby one rotates to the right and the other one to the left. The other type is the furrow press which is mounted behind the tractor. Chisel plough is the other type and this type is important in obtaining deep tillage with limited soil disruption. This type is used to reduce the impact of compaction and hardpan (Kataoka). Fourth, the harrow is another type of farm tool also known as a set of harrows. It is mostly used after ploughing has been done so as to break up the lumps and to achieve fine soil. This tool is mostly used when planting small size seeds like wheat, millet among others. It may also be used to remove weeds and cover seeds after planting (Kataoka). There are several types of harrows and they include power harrow in which the power from the tractor is used to drive the cultivators. The used set of harrows may be ineffective for the land since it makes fine soil, therefore, in case of heavy rains the soil may be washed away. Fifth, the other type of farm tools is the rotary tiller. As the name implies, this tool is used by rotating the tines and blades so as to cultivate the land. It is also known as a rototiller, rotary hoe, power tiller, rotary plough or rotavator. It is mounted on a tractor and it is operated by the power from the tractor. The rotary tiller can also be used by means of propelling itself. This equipment is also used after the plough has been used and the need for it is to break up the soil. It is mostly used in the gardens when planting vegetables and other crops. Sixth, the other tool is a broadcast seeder which is used to plant seeds in the farm. Has the name suggests this tool is used to plant seeds randomly in the farm. This activity is done by spreading the seeds without following a systematic way such as planting the seeds in a line. It can also be used to spread fertilizers commonly known as fertilizer spreader. The tool is also known as a broadcast spreader. The tool is mounted on a tractor normally a garden tractor so as to perform this act of sowing seeds or spreading fertilizers or lime. The small size of the broadcast spreader is handheld with a hopper while the slightly bigger ones are pushed with the spinning disk powered by gearing to the wheel. Seventh, the other tool equipment is seed drill, this tool is used for planting purposes. As opposed to broadcast seeder or broadcast spreader which spreads the seeds randomly, this tool plants seeds evenly and in systematic lines. The rows of these lines are easily controlled so as to achieve an even plantation. The depth of planting seeds is also even with the use of this machine. After the machine has sown the seeds it then covers them, therefore, protecting the seeds from the birds unlike in the case where they are randomly spread and the birds can easily pick them. The tool also saves time since it does all the work of sowing and covering unlike where the seeds are sown by randomly spreading then covered by using human labour (Kataoka). Eighth, the other tool is Centre irrigation and it is used for irrigation. The term irrigation is the application of water artificially to the soil in places where there is minimal rain or in the places with no rain at all. This tool is important in crop production because lands which could have been desolate due to lack of rain are converted into productive lands. This tool is also used to suppress weeds in the farm. Irrigation is also used to prevent soil consolidation, this is the process of changing the volume of the soil by preventing pressure. From the name Centre irrigation, it means that this tool is fixed in the farm therefore, water will be regulated as required by opening and closing when necessary. Ninth, hay tedder is another type of farm tools, this tool is used in haymaking. This tool came into use in the second half of the nineteenth century. After crops like wheat, rice, millet and other crops have been harvested the straws are left in the farm. These straws are useful in making hay for feeding livestock. Therefore, this tool is used in the process of making hay. It also uses moving forks so as to turn the hay and also to scatter the hay. The reason for this activity is to speed up the drying of hay by aerating them. This process also improves the colour and the aroma of hay. This tool is very important in speeding up of haymaking (Kataoka). Tenth, the sickle is another farm tool and it is used for cutting grass, hay among others. This tool is among the smallest farm tools and it is handheld as opposed to other tools which might be mounted on a tractor. This tool is also known as a reaping hook or a bagging hook. It came into existence in the Iron Age and since then it has evolved so much. It started with iron the latter it was made of steel. According to Kataoka, there are many types of sickle which include smooth and serrated blades. Both of these types are used either to cut grass or to harvest mature cereals such as wheat and millet. Causes and Effects of Agriculture in Ancient Egypt To start with, Egypt is known to be a dry land and agricultural practices require some amount of rainfall thus, there are causes and effects which came as a result of agriculture. Some of the causes which led to agriculture in Egypt is the fact that it is a dry region therefore, they used river Nile’s water for irrigation. With the irrigation system such as basin irrigation, agriculture in Egypt was birthed and therefore, there are effects which resulted from it. Some of these effects include increased productivity, productivity was increased as a result of agriculture through irrigation. The other effect is the reduction of poverty, due to agricultural productivity poverty was dealt with. Another effect of agriculture in Egypt was the creation of employment (Lewis). The significance of Pyramid in Ancient Egypt Egypt is well known for pyramids, these pyramids were built as tombs for the pharaohs and their queens. These pyramids were built in different shapes and sizes and they were about eight in number. One of them was built for Pharaoh Khufu and it was known as the great pyramid. Some of these pyramids are among the most magnificent man-made structures in history. These pyramids have a tremendous significant such as economic prosperity and stability. The pyramids had significant uses as far as the well-being of the king was concerned. The reason is, they were used to keep the king’s majesty intact even after his death. Egyptians did this activity because they believed that when the king died his spirit remained with his body thus, they were taking care of his spirit (Bà ¡rta). In conclusion, there are many farm tools and they are used for different purposes. These tools include plough which is used in cultivating the land. The other tool is a mower also known as a lawn mower which is used to cut grass. The other tool is broadcast seeder which is used to plant seed by broadcasting. It can also be used for fertilizer breading. The next tool is the seed drill which is used to plant seeds evenly and in the same depth. The other tool is Centre irrigation which is used to irrigate crops in dry areas and when there is an insufficient amount of rainfall. The other aspect is the causes and effects of agriculture in Egypt and it was caused by drought, therefore, using water from the river Nile for irrigation.

Pediatricians do more for kids than one might imagine Essay Example For Students

Pediatricians do more for kids than one might imagine Essay Pediatricians do more for kids than one might imagine. Theyre available at any time for a childs needs. Parents with concerns about their child can call at any hour to ask questions or make an appointment. But what does it take to become such an important doctor? It takes respect for the field and the proper training, among other things. Pediatricians are doctors who work with little kids, usually from infancy to age 18. Pediatricians work with kids and diagnose and treat infections, as well as treat injuries, defects, malignancies, and many more types of diseases and dysfunctions. With planned evaluation and early involvement, pediatricians recognize and attend to developmental and behavioral problems that result from exposure to psychosocial stressors. They appreciate the defenselessness of childhood and adolescence, and actively support measures to care for their health and safety. Most pediatricians are on call. This means if there is an emergency they can be reached at any time of the day. Pediatricians have a lot of training to do before they can take on the medical field. They attend eleven total years of schooling: four years in college, four years of medical school, one year of an internship in pediatrics, and two years of a pediatric residency. The schooling is not cheap either; in the year 2000, the typical medical students debt was $95,000. Classes that should be taken in college are as follows: one year of English, two years of Biology, one semester of college Calculus or Statistics, and one year of Physics. Pediatricians do go through a lot of schooling, and accrue a lot of debt, but almost all of them will never go back and do different. Pediatricians may work a lot and have a lot of debt to pay off, but their salary makes it all worth it. Pediatricians make money based on how many patients they see a year. An average pediatrician sees 96 patients a week. The majority of Pediatricians make $60,000 to $400,000 a year. That is an amazing amount of money. Now, the price is different for all pediatricians because it is based on their number of patients a week and if they are full time or part time pediatricians. The mean pay for a pediatrician, though, is $139,600 a year. The Pediatrics outlook is really excellent. As long as people keep having children, there will be more and more pediatricians. Pediatricians are still needed in rural places currently. Some places in the United States lack pediatricians! The medical field in general is growing and will still maintain to grow to meet the societys needs in medicine. Pediatricians have an amazing job! Even though the debts can be high, their pay lets them pay it off quickly though. I would love to have this job this is because they get to work with kids and have that overwhelming joy that they helped. Even though they cant help all the kids but the joy that they must have after  saving a life that is incredible! And since the outlook is strong I have faith that in 13 years education training and when I graduate in years there will still be a high need for Pediatricians. I love kids and I always wanted to be a doctorà ¢Ã¢â€š ¬Ã‚ ¦ put the two and two together and you get a Pediatrician. I love what Pediatricians do and they make a difference and I want to.
