INTRODUCTION
1.1 Background of Study
The current world view issue, global warming has been inclined and increasing through time. It is occur due to the release of greenhouse gases (GHGs) that composed mainly of carbon dioxide gas (CO2) which emits from the burning of fossil fuel and from other sources. This has been a threat to the environment, economic and social aspect. The lack of environmental education and environmentalism in oneself can bring to another level of precautionary that must be taken in sustaining the environment. The agricultural sector does give an outrages profit to the country, increasing country’s income, and yet developing economic level, societal status and others.
The agricultural activities does bring benefits to the whole community, but some other things in agricultural issues, such as the waste should not be neglected. Based on BioEnergy Consult, Malaysia is located at a great physical geography where biomass productivity is high which means that the country can take good advantage on this renewable energy resource to supplements limited petroleum and coal reserves. Malaysia, as a major player in the palm oil and sago starch industries, produces a substantial amount of agricultural biomass waste which present a great opportunity for producing biomass energy in a sustainable,

Second generation bioethanol or byproduct is based on raw sample of agricultural waste materials rich in complex carbohydrates like cellulose. This becomes an interesting alternative to reduce competition in the food industry and to generate a promising value to the agroindustrial residues (Ahring et al., 2007; E.P Dagnino et al.,
The Civil War had already ended when agriculture began to develop, bringing about changes across the country, particularly in the West. American agriculture began in rural regions that were urbanized, resulting in a surge of people in the fields and cities where employment and hard labor were supplied manually. It has grown significantly as a result of advanced economic and social changes towards its industrialization for expansion. It increased production among the families of farmers, who served through hard and difficult situations. Throughout the period of 1865-1900, American agriculture changed rural inhabited areas, expanding prospects for migration and urbanization, industrialization growth with advanced machinery, and evolved farming
This high production of biomass energy and reusing waste has more potential than just West Texas. Texas contains several farms, waste-water plants, and agricultural land to utilize for biomass energy
“The vision of a huge fertile garden extending from the Appalachians to the Pacific Ocean had inspired Americans since the early days of the republic” (Out of Many - A History of the American People, pg. 622). Since its beginning, the American ways of farming had always been gradually evolving, but in the time between 1865 and 1900, it transformed like never before. The American tradition of agriculture would experience dramatic changes, as the growth of production and agribusiness would ensue from revolutions in technology, massive increase in population, and alterations in government policies. A major factor in changing the way of agriculture was the new technology being developed in farming and transportation.
In old days, agriculture or other primary industries were the main pillar of Michigan state’s economy. “Most Native American settlements in the Great Lakes region were along river valleys or near the shoreline of the Great Lakes, and most of the population located in the southern half of the Lower Peninsula. Tribal settlements were not permanent, with groups moving to new locations every few years. Although agriculture was limited by soil conditions and dense forest, the Native Americans of this region did cultivate crops. Corn, beans, and squash were grown and wild apples, berries, nuts, game, fish, honey, and wild rice provided other sources of food.
People may know about climate change and the drastic changes it is having on the environment, but what they may not be aware of is that another degree increase in the world’s average temperature will cause even bigger problems for people all over. Climate change is long term shifts in temperature and patterns in the weather. Greenhouse gasses, gasses that trap heat in the atmosphere causing it to warm up are at an all-time high due to humans and the amount of fossil fuels we use. The most crucial result of climate change is global health, but animal endangerment and the rise in sea levels are also very important effects.
Almost anyone who will read this essay has undoubtedly heard of the climate phenomenon Global warming. Global warming is a topic that gets discussed very often nowadays, most notably during political debate and discussion. Politicians use certain stances on global warming to appeal to voter’s emotions and logic in order to gain votes and support for their campaign, however climate change is nothing new, during the past several hundred thousand years the Earth has heated up and cooled down and even experienced so called “ice ages”, which is a period where glacial deposits located at the northern and southern hemispheres have grown due to dramatic global cool downs. Don’t be confused by climate terminology though, the global warming so widely
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem.
The Controversy on Agricultures Mankind has gone through numerous changes that have defined life today. Humans have developed technology and discovered resources that are essential to ones everyday life. Some of the changes weren’t for pleasure but vital to survive on Earth. These changes may not benefit humans but allow us to survive: agriculture. Jared Diamond explains in the article “The worst mistake in the history of the Human Race” stating that “…the adoption of agriculture, supposedly our most decisive step toward a better life, was in many ways a catastrophe from which we have never recovered.”
Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
The agricultural technology that was invented during the medieval ages resulted in social and economic developments which affected the lives of those living in that period. The new machinery allowed the townspeople to grow a surplus of food and in result learn new specialties and trades. “When these people could produce a surplus, they were freed to do other things, which provided the basis for towns, cities, and civilization”( flowofhistory.com). Civilian life was made more comfortable because of the advancements that were made through the ages.
Introduction: “Sustainable agriculture is the efficient production of safe high quality agricultural products, in a way that protects and improves the natural environment the social and economic conditions of farmers their employees and local communities and safe guard the health and welfare of all farmed species“ There are three main principles of sustainable agriculture, the three principles are: 1. Economic sustainability 2. Environmental sustainability 3. Social sustainability With the human population continuing to rise, it is vital that the agricultural industry becomes more sustainable to meet the needs of the growing population. One of the impacts of this growing population is an increase in land usage for settlement purposes.
In most foods, microbial contaminations occur predominantly at the surface, meaning using edible films such as chitosan allows minimal space between the foods’ surface and its’ environment. However, the coating has weak mechanical properties, and is permeable for gas and water vapour. Blending chitosan with starch improves its mechanical properties and allows a better novel food preservative. ADVANTAGES: - As chitosan is the second most abundant carbohydrate after cellulose, it’s not unusual that its waste exceeds 25bn tonnes per year.
Global Warming causes and solutions The majority of scientists around the world have a fear of global warming and its effects on nature and humans around the world. Global warming is considered as one of the most threatened in our world today. This essay presents and explains the impact of global warming on earth and suggests to finding the best solutions can be done in order to minimizing those reason that affected on raising the temperatures to avoid this problem.
Indeed, no citizen of the earth can afford to remain aloof from the issue related to the environment. It is therefore, essentially important that the study of the environment becomes an integral part of the education process. Environmental education increases public awareness and knowledge about environmental issues or problems. In doing so, it provides the public with the necessary skills to make informed decisions and take responsible actions. Needs and importance of positive attitude and awareness towards environment:
What is global warming? Global warming is defined as “ an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate, and that may result from the greenhouse effect" (“Global warming”). Natural events and human that causes global warming are believed to be factors to increase in average temperatures. This essay looks into the growing problem of global warming and suggests reasonable solutions to it. It also evaluates the effectiveness of these solutions.
