* Impacts on Agriculture The region’s economy depends on crops; the majority of the Great Plains is used for agriculture. With temperatures increasing, extreme heat, and droughts becoming more frequent, the aptness for certain Great Plains’ crops will change. Livestock will also be put under heat stress and are more at risk for disease. Poor agricultural land management combined with drought can also cause many disastrous events, for example the Dust Bowl of the 1930s. With expected warming temperatures and constant burdens on water and land resources, negative impacts will certainly affect the agriculture.
Land species- species adapted to arctic climate at risk. Marine species- species dependent on sea ice, including polar bears, walruses etc. will decline. Carbon cycle changes- replacement of arctic vegetation with more forests will lead to higher productivity and increased carbon dioxide uptake, but methane emissions from warming wetlands and thawing permafrost could counterbalance this positive impact. 4.
What impacts might result if everyone in the world enjoyed the same lifestyle? For example, what might the impacts be on: • Earth’s climate? The earth would be tremendously ruined because everyone would be using fossil gas that we burn for our usage, and the fertilizer that farmers use on their farms to grow crops • The health of ecosystems and biodiversity? A lot of animals will go instinct so we will have food storage. We will also have air and water pollution that will start diseases for us humans.
That the earth climate with continues to change from all business practice conducted from around the world. With the weather change from the changing in temperature which is causing large portions of ice to melt and crash into the ocean. This structure to the earth has a major impact to how and when foods are growing and put out on the market for profits and at what dollar cost to citizen as a hold. The population growth will also cause change with food and water supply as well the decrease in animal sources will continue to decrease. Section B: Fill in the chart with complete sentences.
If this dry climate were to change to a wet one, many animals would have little time to adapt and plants would most likely drown. If the ice in the Arctic Ocean disappears, the animals that depend on that ice will have nowhere to go. Animals and plants living in colder climates will have to adapt to new biomes once theirs has changed. It is easier for animals to migrate to find a better climate, but many seasonal cycles will change – like birds that fly south for winter would get confused and mix their seasons – as well as mating seasons changing. Although plants can’t easily change location, they will start to blossom and bloom at unusual points in the year.
Also, since new species of plants have invaded the arctic some animals can’t adapt to them, like the Caribou which numbers have decreased. 4. If climate change continues then half of the arctic tundra could be gone replaced by trees and lush vegetation by 2050. This would cause most plant
| | The FACTS-I experiment is testing how elevated CO2 influences tree growth, carbon concentration in soils, and other factors over a ten-year period. | Greenhouse Effect | The greenhouse effect is caused by atmospheric CO2 but is necessary to keep the surface of the Earth at a habitable temperature. | | Increased levels of atmospheric CO2 could cause global warming and significant climatic change. | | Life on Earth is protected from dangerous radiation by a protective layer or ozone molecules present in the atmosphere.
Maintaining integrity and public awareness is a very difficult task in the environmental realm because global warming and climate change in the ‘green’ movement is so prevalent. Environmental integrity requires Enbridge to follow environmental rules and regulations within the area of the proposed pipeline, and offset its impact through other actions. Enbridge is investing in low-environmental –impact energy sources – both renewable and alternative- that help complement its core operations and provide environmental benefits. This helps to reduce greenhouse gas emissions and addresses the issue of global climate change. By using wind power, solar power, geothermal power, waste heat recovery and fuel cells Enbridge currently avoids over 1.5 million tones of greenhouse gas emissions each year.
In my paper I will discuss each of these laws and the impact that they have had on the environment and industry. The Clean Air Act (CAA) The purpose of the CAA is to enact legislation whose purpose is to protect our Nation’s clean air by regulating air emissions from stationary and mobile sources. This law has recently been the forefront because of the growing concerns relating to global warming and greenhouse gas emissions. We have seen a major push towards developing cleaner and safer fuel alternatives to reduce our dependence on fossil fuels; we are beginning to see a greater use of recycled materials in manufacturing; and reducing the use of fluorocarbons. All of these measures are intended to reduce of carbon footprint and promote clean air.
The needs of future generations are being met by current policies of sustainable development. To what extent do you agree with this statement? Modern lifestyles cause shortage of natural resources, pollution, destroying ecosystems, increasing social inequality, climate change. Current policies of sustainable development are the best way for solving these problems and it can respond to the diverse needs of existing people and future generations. “Sustainable development provide for the fundamental needs of humankind with doing violence to the natural system of life on earth” (Marten, 2006).
