1.     Introduction of the Earth Song

URL of Earth Song’s music video: https://music.baidu.com/mv/2191229

“Earth Song” is the third single from Michael Jackson’s album History: Past, Present and Future, Book I. It is the fifth song on the second disc of the album. It is a ballad that incorporates elements of blues, gospel and opera. Jackson had a long-standing history of releasing socially conscious material such as “We Are the World”, “Man in the Mirror” and “Heal the World”. However, “Earth Song” was the first that overtly dealt with the environment and animal welfare. It centered on the destruction and rebirth of Earth.

The music video for “Earth Song” had an environmental theme, showing images of animal cruelty, deforestation, pollution, poverty and war. Jackson and the world’s people unite in a spiritual chant—“Earth Song”—which summons a force that heals the world. Using special effects, time is reversed so that life returns, war ends and the forests regrow.

3. Extensive reading materials (Environmental problems in China)

Water All Dried up

    CHINA endures choking smog, mass destruction of habitats and food poisoned with heavy metals. But ask an environmentalist what is the country's biggest problem, and the answer is always the same. “Water is the worst," says Wang Tao, of the Carnegie Tsinghua Centre in Beijing," because of its scarcity, and because of its pollution." Water," agrees Pan Jiahua, of the Chinese Academy of Social Sciences." People can not survive in a desert." Wang Shucheng, a former water minister, once said:" To fight for every drop of water or die: that is the challenge facing China." He was not exaggerating.

China is using up water at an unsustainable rate. Thanks to overuse, rivers simply disappear. The number of rivers with significant catchment areas has fallen from more than 50,000 in the 1950s to 23,000 now. As if that were not bad enough, China is polluting what little water it has left. The Yellow River is often called the cradle of Chinese civilization. In 2007 the Yellow River Conservancy Commission, a government agency, surveyed 13,000 kilometers( 8,000 miles) of the river and its tributaries and concluded that a third of the water is unfit even for agriculture. Four thousand petrochemical plants are built on its banks.

The water available for use is thus atrocious. Song Lanhe, chief engineer for urban water quality monitoring at the housing ministry, says only half the water sources in cities are safe to drink. More than half the groundwater in the north China plain, according to the land ministry, cannot be used for industry, while seven tenths is unfit for human contact, i.e., even for washing.

In 2009 the World Bank put the overall cost of China's water crisis at 2.3% of GDP, mostly reflecting damage to health. Water shortages also imperil plans to expand energy production, threatening economic growth.

The best answer would be to improve the efficiency with which water is used. Only about 40% of water used in industry is recycled, half as much as in Europe. The rest is dumped in rivers and lakes. Wang Zhansheng of Tsinghua University argues that China is neglecting its urban water infrastructure (sewerage, pipes and water treatment plants), leading to more waste.

Rather than making sensible and eminently doable reforms in pricing and water conservation, China is focusing on increasing supplies.

The Problems of Air Pollution

    Millions of people in China are breathing a hazardous cocktail of chemicals every day. These chemicals are caused by coal-fired power plants, factories and vehicles, and are responsible for heart disease, stroke, respiratory illnesses, birth defects and cancer.

Air pollution in China is mainly caused by burning coal in factories and power plants and oil combustion by vehicles.

The impacts of air pollution

    Air pollution often has long-term health impacts that build-up slowly over time. It may also cause non-specific problems, such as weakened immunity. As such, it is often easy to overlook the health impacts of air pollution. That's why public education and outreach on the issue of air pollution is highly important.

    Air pollution has been linked to increased incidences of cancer, heart disease, stroke and respiratory illnesses. On a less severe level, it is associated with asthma in children, and thus impaired quality of life for many kids.

Air pollution in China

    With a booming economy and ever-increasing demand for energy, China has built new coal-fired power plants at an astonishing rate. Today, coal provides not only 80% of China's electricity, but also the lion's share of its air pollutants, from soot to sulphur dioxide.

    While cars and trucks also contribute to air pollution in cities, it will be impossible to improve air quality in China without moving away from coal.

    Coal burning is the biggest contributor of air pollution in Beijing and surrounding area, according to a University of Leeds study sponsored by Greenpeace East Asia. Previous studies have linked outdoor air pollution to premature deaths and child asthma in the industry-intensive region which arguably has the worst air quality in China.

    China simply cannot afford to allow air pollution to continue taking such a heavy toll. The country's rapid growth in coal consumption has been brought on by extensive industrial expansion, which in turn, has increased pressure on the environment and public health conditions. In order to turn around the deteriorating air conditions, China must fundamentally change its development model, starting with a significant reduction in coal consumption
