During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be done about it. For example, carbon dioxide can stay in the atmosphere for nearly a century, so Earth will continue to warm in the future.
Raising cattle in the northern part of the United States is more than just raising cattle and being cold while you do it. Keeping your cattle with fresh water, feed, and, hay is sometimes a task anywhere in the country much less when you have to deal with temperatures that are twenty degrees below zero. When it is this cold outside your cattle do not have fresh water until you go and break the five to ten inches of ice on top of their water trough. Feeding your herd also creates problems. When you get the hay for your herd to make it through the winter it can not be just any hay. You have to send your hay to a laboratory to get it tested. By having your hay tested this tells you if your hay has enough protein for your cattle to make it through
Overall of this assignment, I have understood that our earth is "sick". We humans need to "heal" the earth. Global Warming have causes many problem for human but we human who make global warming happens. Many people have died because of disease or disaster. It also affects the economics of the country. However, we need to be reduce the global warming by using less gasoline, recycle and human should help to reduce global warming instead of making the earth temperature increased. Our generation should start taking care of the earth because in the next generation they will suffer if we do not do reduce global warming. Therefore, global warming is a serious issue now. As a business student we are learning it because we need to understand the effect of climate change that will affect us when we have our business and we can start saving the earth.
