Because of the industrialization and urbanization, people create a prosperous and busy lifestyle. Especially for people who pursue luxuries and goods, they spend lots of money on it, causing business corporations to increase the amount of productions and materials, which poses threat on earth. Also, by commercial advertisements and public media, people are strongly influenced by America lifestyle, a "enjoying" lifestyle that depend on hoe much you consume and spend. However, people enjoy, but our planet doesn't at all.

Global warming is getting much more attraction in recent years. Rising of the sea level, climate changes, species extinction took place the political scandals, hopping on the first page of the newspapers. More and more researches reveal threatening truth to the public, as well as increasing number of organizations trying to persuade people to eat vegetables instead of having a meat diet. It's an issue nobody could ignore and a problem should be solved by everyone.

What's to be done? That's really a hard question for both experts and citizens. Take the vegetarian diet as example. According to the research, carbon dioxide discharged by producing meat from cows and pigs is 20 times more than by producing vegetables and crops. It sounds really scary, but only by a man's effort; it's not useful because farms keep producing them! It's important to make the government know how global warming affects our country. Only by gaining attention from the authorities can we make sure having great help to the earth. Once we have vegetarian diet about twice a day, we don't need that much meat and the farms will reduce the production of meat because of the decreasing of meat purchasing.

Also, it's important to teach students the importance of protecting the environment and how to do it. First, make good use of paper. Rain forests are disappearing fast these days, causing the rate of carbon dioxide rising. Every space of used paper is available. Second, use products which pose little threat to environment. Carbon footprint is a good point to measure how much a product produces carbon dioxide. Governments are urging companies and factories to mark the carbon footprint on their product, so consumers are able to choose eco-friendly products. It's really important for students to develop concepts of protecting our planet because they are the people who will be the manager of most businesses in decades, the health of the environment are depending on them!

Moreover, we should always buy food produced in our own country. Although some may think other countries' products taste better; however, it burns lots of fuel by traveling from foreign countries to our homeland. During this unnecessary trip, the burning of the fuel produces greenhouse gas! Besides, if people buy food produced by ourselves, they can encourage our agricultural activities. By elevating our agriculture, maybe we can do less industrial activities.

Overall, people don't need that much material around, life can even simpler than we think. Nevertheless, materialism is still highly admires worldwide. Maybe it would not be effectives if only ourselves do it, but try to tell others this important concept! If one could at least influence three people, the conscience of protecting our home will spread out quickly.

Documentaries about global warming aren't appearing these days without any reason, it's a warning to human kind. Everyone is responsible for protecting our earth, once we face the responsibility seriously and try hard to improve the situation, we'll be able to live in our beautiful planet forever.
