Going Vegetarian
Is carbon very important in our life? Can humans live without carbon dioxide in the air? Can people depend on plants in their diet only? Some people say yes, people can depend on a vegetable diet and have a good health while others say food without meat is not enough. People want to live in their life without a fat body; they want to enjoy themselves while they are alive. Therefore, vegetarian food should be the main food in the future, because it is healthy to humans, it is easy to cook and cheap, and it keep the environment clean.
The first reason that makes vegetarian food the main food in the future is that it helps people to keep their body healthy. Vegetarian food will not make the body of human very big, since vegetarian food does not have fat like animal food does. It is well known that a vegetarian diet has a large number of fibers which help to protect the large intestine. In addition, vegetarians are healthier than their peers who eat meat a lot because they are subjected to a lower risk of diseases such as cancer, heart disease, high blood pressure and other health common problems. Next, vegetarian food is easy to cook. Vegetarian cooking does not take a lot of time like meat. Anyone can make vegetarian food breezily with a recipe. Also, vegetarian food is not expensive like meat. In the US, meat is not too expensive as in other countries, but some people turn to vegetarian food because of religious or health issues, and these become more important in their lives later.
Finally, vegetarian food keeps the environment clean. There are some foods such as vegetable that produce less carbon than others like beef and dairy products. In Reville (2009), “the good news is that some foods produce much smaller carbon footprints than others and have the great added bonus that they are also much better for your general health” (para. 6). We know that carbon is very important for plants, especially in the chlorophyll process, but carbon is very dangerous if it level is too high. Some people consider carbon to be one of the polluting gases.
In conclusion, people must know first what vegetarians mean; vegetarians are people who do not eat meat, fish, or chicken in their diet and eat a varied vegetarian diet. Vegetarian food is very important since it is helps people to keep healthy; anyone can buy and cook it, and it is keeps the environment pure. A diet of plants is healthy because it contains very low fat and high fiber.

Ozone loss
In Leahy’s (2008) article, “Climate Change: Chemical Lobby Weakening Ozone Treaty,” he claims that the rate of skin cancer will be raised and also the climate will be changed because of the ozone problem. The author says that, as an example, more than ten thousand people in the US will die and one million or more have skin cancer. In addition, he shows some views of scientists who say that the ozone layer will be damaged within the next 40 years and a lot of people will have skin cancer. So he says that the people should protect the ozone layer by keeping huge quantities of carbon dioxide out and not enter our atmosphere. Also, he explains that a lot of the organisms, animals and plants, would not be continuing in this life. Finally the author suggests some solutions that use a little amount of energy.
What is the ozone layer? How would the life be without the ozone layer? What will life become like if the temperature reaches 50 Centigrade? The ozone layer is part of the atmosphere that surrounds the globe. People believe that destroying the ozone layer will cause the end of the world. People want to live in this life without any troubles; they want to live without pollution and with good health. The ozone layer has become a global issue, which people around the world focus on because of the risks involved. Therefore, the ozone layer is very important, because it protects life from high temperature, organism extinction, and environment pollution.
First of all, the temperature will rise if the ozone layer is lost. Imagine that the temperature today is 125 Fahrenheit; what will happen? A lot of people will have skin cancer and damage to the eye will be increased. According to Leahy (2008), “A less than three-minute exposure to the sun in Hawaii would have resulted in sunburn. Skin cancers would be at least 650 percent higher” (para. 10). High temperature causes inactivity in humans, and so the production will be decreased.
Next, the ozone layer protects the plants and animals from extinction. Erosion of the ozone layer will affect plant life and agriculture, as there are some plants that have a great sensitivity to the ultraviolet radiation that affects their production and is detrimental to the mineral content and nutritional values and thus cause a weak agriculture. Most of the plants and animals need a median temperature to survive. High temperature burns the plants and makes trouble for the animals’ life.
Finally, erosion of the ozone layer will raise the rate of the environment pollution. It causes forest fires and desertification. The smoke coming from the fire will spread in the air and make breathing a difficult process. Also, plants absorb carbon dioxide from the air and produce oxygen. Water pollution will not let the plants grow well, so the carbon dioxide will increase in the atmosphere and then affect the organism’s life.
In conclusion, the ozone layer is useful for many things; it is useful for the humans, animals and plants, and it is useful for the environment. The ozone layer protects the Earth from ultraviolet radiation released by the sun, which causes severe damage to humans. People should find solutions for the environmental threats to live on the Earth with good health.
