It is safe to say that New Zealand is largely a farming nation since farming makes up a high percentage of the country's export earnings. The country's climate ranges from regions in the north that are considered "warm subtropical", to "cool and temperate" in the south. These diverse areas allow for numerous kinds of farming which are vital to New Zealand's economy. All over the country there are deer, llama, ostrich, goat, cattle and sheep farms, and though they get no subsidies from the government, they still play a large part in contributing to overseas markets with their beef, wool, dairy products, other meats, hides, venison (from deer), and goat fiber. It is said that there are about 20 times as many sheep as there are people in New Zealand, but since the country has become increasingly more developed in recent years, this figure has dwindled and continues to do so. This is not to say that the development of human civilization in New Zealand is the preeminent concern for threatening the country’s animal farming industries. In fact, climate change is a greater concern, and if global temperatures continue to rise as they have been over the years, New Zealand ’s animal farms could take a hit. Animal farms aren’t the only widespread economy drivers in New Zealand. In addition to animal farms, New Zealand is also rich with tree farms. This way they can harvest trees for lumber without touching the indigenous forests, most of which are protected indefinitely, like the huge rainforest on the western side of the south island. 30 percent of New Zealand is covered in forest, including both natural and "planted production" forests. This is a large and seemingly healthy percentage relative to most other countries in the world.

Whether the positive aspects of a warmer climate will prevail over the negative aspects remains to be seen, but it will certainly have an impact on agriculture in New Zealand and elsewhere. Humans have never been in this situation before so it will be something that we surely will find out in the future unless something is done to regulate the amount of greenhouse gases that are emitted into the atmosphere.

In Australia the climate is expected to become significantly warmer. Noting that the impacts of climate change will vary from region to
2003) and already more than half of the land suitable for pastures is subject to overgrazing and erosion, posing a risk for food production in the near future. The erosion level of pastures and rangeland exceeds the erosion rate of cropland by roughly six times, meaning, that the land becomes unusable for agricultural use at higher rates when used for meat production rather than vegetarian foods. Moreover, croplands are not exclusively used for human consumption but animal feed accounts for 40 percent of the harvest. Thus, livestock requires land to graze while also depending on land to produce feed. The FAO (FAO, 2012) estimates, that due to the high land-use of conventional agriculture and an increasing demand for omnivorous products such as beef and milk, more than 10 billion hectares of forest are lost to expand pastures and grasslands to feed

Not only will this be catastrophic for the humans, but animal and plant life will suffer too (“Global Warming” 4, 10, Than 1-4). The oceans will become more polluted and warmer which will cause fish along with coral reefs will die (“Global Warming” 4). The heat will bring animals to extinction; their migration patterns will be altered, change their diet, and force them to live in different locations in order to find a suitable climate (Than 1). Additionally, the warming will hurt the crop production. Crops have a very specific range of temperatures they should grow in order to maximize their yield, and if the earth is going to be above the temperature then crop yield will suffer. Projections for the year 2050 show...
In this essay, the effects of climate change on agriculture and how to manage it shall be discussed. Climate change has and will greatly affect agriculture. As time progresses, the effects of climate change will worsen and become detrimental. Mendelsohn and Dinar (2009:1) state,” if future climate scenarios lead to a widespread reduction in food supply, there could be massive problems with hunger and starvation”. Climate change is a change in global climate patterns which is mainly caused by the increased levels of atmospheric carbon dioxide produced by fossil fuels. The writer chose this topic because climate change is a global problem that will pose a threat to people’s lives around the world and must be dealt with sooner than later.
High temperature causes the glaciers to melt which raises the sea level on earth which will cause having more frequent flooding and very low-lying land could get submerged completely, It will also affect the food as too much water flowing into the agricultural lands will spoil the
A United Nations report states that land used for animal agriculture, both for grazing and production of crops fed to livestock, takes up an astounding 30% of land on Earth. ("Meat Production Wastes Natural Resources") To meet the industry’s demands, over 260 million acres of forest in the U.S. have been cleared to grow grain fed to farm animals. ("Meat Production Wastes Natural Resources") With that in mind, the meat industry also dumps disease-causing pathogens through animal waste that pollutes water and forces the need for waste lagoons to be constructed, which are susceptible to leaking and flooding. ("Facts about Pollution from Livestock Farms”) Scientists say that about 14% of the world’s greenhouse gases are released by said agriculture industries, which is a growing concern for climate change and global warming. (Silverman) The meat industry uses one-third of all the fossil fuels consumed in the United States. (Moore) There is no question that farming animals has a negative effect on the environment and steps should be taken to mitigate air and water pollution risks and future deforestation. If animal agriculture was phased out, land used for animal grazing could be returned to forest land and some of it converted into fields for cultivating crops for humans. A global shift toward veganism, resulting in the elimination of the meat and animal agriculture industries, would protect the environment from various detrimental effects.
There is much to be said about how exactly meat is being produced. In the present day, there are hardly any farms out there that still practice the traditional and environmental - friendly way. Animal agriculture is widely used all over the world and greatly contributes to climate change. Meat production leads to global warming because of the combination of carbon dioxide, methane, and nitrous oxide. The process of raising animal is the major source to these harmful gases. It is vital to save the world from the worst impacts of climate change by reducing meat consumption. However stopping this meat eating system is extremely difficult, given that we had been consuming meat ever since our ancestors domesticated animals for that purpose. Over the decade Animal agriculture has been getting worse and worse. In 1973 when the Secretary of Agriculture Earl Butz announced ‘’ what we want out of agriculture is plenty of food’’, overproduction was encouraged and lowering the price of meat was carried out; this originally started when there was a massive increase in corn (Wolfson). In order to keep up this mass production of meat, multiple pounds of grains are fed to livestock. Livestock industries depended on corn and soy based food and used over half of the artificial fertilizer used in the United States (McWilliams).
The plants we grow for food needs specific resources to thrive, which includes the night temperature and enough water. A changing climate could create a lot of problems. Climate change could make it too hot and also make it too cold to grow crops in some areas of the world and also climate change can cause drought, which is made by the unavailability of water for irrigation. Climate change is likely to cause stronger storms and more floods, which will damage the crops. . Latin America and Southern Asia is seeing it in lethal storms and floods whereas Europeans are experiencing it in melting glaciers, forest fires and disastrous heat waves (Pearce, 2006). Deforestation is another anthropogenic factor that is causing climate change because of the need for fossil fuel, agricultural lands are being used. Forests are being burnt down by humans on a daily basis. As agricultural lands becomes less in need of growing population, people extend their space by cutting and clearing forest. The land beneath the forest sometimes tends to be unproductive and lacks the natural chemicals for a growing. The plantation will serve as a source of food for a few years after then the land becomes useless because of its infertility, it nutrients get depleted and used up. Deforestation results in numerous problems such as destruction of our natural resources, ecosystem, wildlife,
As the turn of the twentieth century approached, the livestock industry became increasingly more powerful than ever before, and meat became much more affordable for working class families (Best). That was, until Francis Moore Lappé’s book, Diet for a Small Planet was published in 1971, and exposed the grave danger that the meat industry set upon the environment and specifically the earth’s land (Best). With a population that grows as rapidly as the human civilization does, it is imperative that changes are made to ensure habitat conservation for years to come, and it seems that a vegetarian diet is the way to help. Livestock farms and land to grow feed for those animals has taken the space of some of earth’s most wonderful resources, using up recreational land, wildlife habitat, and wilderness. The average American diet consists of 270 pounds of meat each year, and that rounds up to approximately 20 acres of land (Vidal). Livestock is said to take up 30% of dry land on earth, and 80% of the agrarian land within the United States. Becoming a vege...
“Currently 80% of the world’s agricultural land is used directly or indirectly for animal production. In the US over half the total land mass is used for the production of meat and dairy products” (Clarke).
Climate change is one of the major issues surfacing earth over the past century. The earth’s temperature has increased over the years leading to detrimental effects on the economic and life sources of people, especially that of agricultural production and livestock. The Merriam-Webster online dictionary (2014), defined climate change as a change in global climate patterns apparent from the mid late 20th century. The Intergovernmental Panel on Climate Change, IPCC, (2007) predicts that by 2100 the increase in global average surface temperature may be between 1.8° C and 4.0° C. With increases of 1.5° C to 2.5° C, approximately 20 to 30 percent of plant and animal species are expected to be at risk of extinction. Moreover, the IPCC (2007) purported that climate change has severe consequences for food security in developing countries. There are numerous factors that are solely responsible for this change which are both natural and man-made. Climate change has led to a decrease in quality and quantity of plant produce and livestock because of heat stress, drought and an increase in plant and animal diseases.
...ased adaptability among food crop species. While economic issues limit the ability of developing countries to increase agricultural inputs, these regions can find an advantage in the fact their agricultural practices tend to be more flexible. Meanwhile, technologies available to more developed countries are increasing the speed with which new cultivars can be developed, and the ability to understand and improve agricultural management practices. Ultimately, best results to developing agricultural systems which will provide a source of sustainable food for the entire world as climate change progresses; will be a result of a collaboration between scientists and farmers. When practices allowing for greater agrobiodiversity are employed the level of sustainability of our agricultural systems will advance and agriculture can become truly adapted to the new global climate.
...o climate change. All of these have caused an impact on the ability to produce crops and grow agriculturally. Climate change has been increasing the number of droughts, floods, health hazards of employees, natural disasters, and sea level elevations. All of these put in danger the crop productivity resulting in famines and food price increments. Climate change affects agriculture in every country differently due to its location. Countries such as Canada and Russia are being affected positively by climate change since it has enabled the country to prosper agriculturally. Other countries cannot handle drastic temperature changes, such as Sudan and Bangladesh, whose agricultural growth has been affected negatively by the climatic changes. Agriculture is fundamental in a country, creating a balance between agriculture and the increasing climatic changes would be ideal.
