Agrochemicals and pesticides present significant part of the agricultural sector. Agro-industry plays an important role in the country economy. Chemicals are used in a wide variety of products and play an important role in the world economy. They are constituents of materials, are used in preparations and products and are embedded in complex physical systems. While chemicals are a significant contributor to national economies, sound chemical management across the life cycle - from extraction to disposal - is essential to avoid significant risks to human health and the environment, along with their associated economic costs, and to maximize benefits for human well-being. Growth in chemical production and use has slowed in many of the developed countries that previously dominated the market, while it has accelerated rapidly in a number of developing countries and countries with economies in transition. These countries are, increasingly, the drivers of global expansion in production and use of these chemicals. The global chemicals industry has grown rapidly over the past several decad...
Agriculture plays an enormous part in having a functioning society. The farming fields in the
There are many issues regarding the raising and producing of various livestock animals, and the use of pesticides on various types of crops. The movie Food.Inc does a good job explaining these issues, but in a very biased way. It makes agriculturists look like terrible people, when this is not the case.
What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.
Agriculture—it’s something that not very many people know much about. However, it is important for us to survive. Almost everything in our everyday lives is agriculture-related, from the food you eat to the clothes you wear.
Over the years, meat eating has grown dramatically in many countries. Demand for meat production increased at a fearsome speed, which led to producers using pesticides and fertilizers on their crop. Because of our exponential population we could not begin to feed the population of the world without them. Farmers will need to increase the amount the chemicals used on their crops and animals to accelerate production process i...
Many companies all over the world produce chemicals for their products that are harmful to the environment, human health, and to all living species. Green Chemistry is the use of chemistry for the prevention of chemical pollution to the environment by using chemicals that are benign, or not harmful. The Environmental Protection Agency (EPA) states that the mission of Green Chemistry is, “To promote innovative chemical technologies that reduce or eliminate the use or generation of hazardous substances in the design, manufacture, and use of chemical products.” Green Chemistry contains any aspects and types of chemical processes that reduce the negative effects of certain chemicals, in a way, using chemistry to fight chemistry.
Instead of using pesticides in farming a better alternative would be biological control. This is when a natural predator is released into the crop growing area as a result the number of pests can be reduced.
Hazardous materials are in almost every community placing everyone at some level of contact with various chemicals almost daily as they exist throughout the community and in our households. Chemicals are used for a variety of purposes such as in the water purification process, by farmers to produce a higher crop yield and are used in households and almost every business. Not all chemicals are hazardous but most pose some level of risk to people...
Chemicals can be quite costly as well, ranging from hundreds to thousands of dollars. With these chemicals, you need the proper equipment to distribute the chemicals effectively. Many dangers are faced when releasing the chemicals, for example, the hours used up on the equipment will make your machinery more susceptible to breakdowns. The chemical could also damage your crop if not used correctly. This damage to the crops causes the farmers’ average yearly income to decrease intensely.
Chemical farming has become such a cultural norm that humans have turned a blind eye to what is really happening behind the scenes and have come to accept what the big manufacturing companies have told us. What these companies don’t want us to know is that when you produce food on a conventional farm you are producing food that is harmful to the environment. Conventional farms use fossil fuel derivative fertilizers to help add nutrients to the soil, but “these are the reason the earth is experiencing dangerous climate changes” (Sustainable Table). Also, the quality and consistency in the crops are lowered when they are planted on a chemical farm because many companies use artificial manure that leads to “artificial nutrition, artificial food, artificial animals and finally artificial
Applications of chemical science have contributed significantly to the advancement of human civilization by providing a growing understanding and ability to manipulate chemical molecules. Chemistry controls the tastes and flavors of the food we eat, the scents we wear, the look and feel of our clothes and how the world appears around us. Chemical behavior and the interaction of elements and molecules give us the energy we need to heat our homes, to drive our cars and to power our lives. This chemical behavior governs the distribution of the natural resources that we need and industrial processes required to extract them. In turn we rely on chemistry to turn them into products we rely on every day. Chemical Industry produces 70000 different types of products that are used by individuals as well as other industries. Chemical sector is of strategic importance to the
The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil, in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the soil was severely damaged from monoculture (The cultivation of a single crop in a defined area).... ... middle of paper ... ...
On the positive sides, it is evident that environmental protection and sustainability is evolved as one of the prime challenges specifically for the developed countries including Pakistan, United States, China, and other regions. In order to respond to the challenge and promote environmental sustainability, a range of technological developments have been made (Sun & Reed, 2010). For instance, industrial waste water is normally dumped into the open reservoirs of water that resulted in extensive water pollution. Technological developments in this regard have allowed the industrialists to treat the water in order to minimise its negative impact on the environment and fresh sources of water. For this purpose, water treatment plants are developed in major developed countries around the globe (Baier & Bergstrand, 2007). International trade plays a critical role in this regard and provides an opportunity to the developing countries to get these technological innovations from the developed countries. This will positively contribute towards global environment. Aside from this, international trade also provides understanding to the members from developing states about the role of environment and environmental sustainability towards business objectives of the firms (Korinek & Melatos, 2009). In other words, it also acts as a platform for understanding and awareness for
Organic farming has mushroomed drastically in importance and influence worldwide from its modest beginnings in the first half of the last century. Organic farming is production of food and livestock without the use of herbicides, pesticides, weedicides, fertilizers or genetically modified organism and use natural resources such as manure and compost instead. In other words, it is a production system which maintains the quality of soil ecosystem as well as human beings. According to IOWA State University, “the chemicals were not used for farming before World War 2. A number of munitions used in farming have contributed to field of agriculture. For instance, ammonium nitrate used as ammonium nitrate fertilizer”.
The pesticide is a controversial topic since farmers are used it to gain their yield. Especially, pesticide is discovered during World War II as a chemical weapon that mixture of multiple chemicals together to kill human. Therefore, Chantries redesign pesticide to kill an organism where and when we don’t want it. Because people want to go to the grocery store to buy the perfect product, pesticide makes it happens and with a little cost for farmers. Nonetheless, pesticide also is the expenditure of life expectancy, which directly threatens people and poses risk of mortality rate. Abusing the pesticide has multiple affects on our society, (Add).
