Earth Crisis

The world is warming. Global warming refers to the rising average temperature of air and Ocean on the earth's surface since the 20th century, which is expected to continue. Evidence shows that for every 0.6 degree rise in temperature, 150000 people die every year as a result of the negative effects of global warming. Among them: glaciers, permafrost and sea ice are disappearing, sea water level is rising, seasonal imbalance and weather become more extreme. When the temperature rises further, it will cause more floods, droughts, pestilence, famine and other situations, and damage the entire ecosystem.

These climate changes are likely to be caused by the greenhouse effect. Recent research has shown that carbon dioxide emissions are twice as fast as the earth can absorb. At present, the carbon dioxide content in the atmosphere has reached 380ppm, which is the highest record since 4000000 years, aggravating the environmental damage caused by the greenhouse effect.

Climate change is eating up ancient glaciers high in the Andes. Locals will face a crisis of faith.

Adelain penguins drift on ice floes in Australia, Antarctica. According to NASA's aerial survey, the Antarctic ice sheet melts 57 billion tons every year. These emperor penguins are facing rapid reduction of their living areas. At the same time, the melting of the Antarctic ice sheet is raising sea level, and small island countries like Tuvalu even face the fate of being flooded as a whole. The expansion of the earth's water area leads to the extension of the rainy season and frequent floods.

Kenya, Kilimanjaro Mountain is located in the equator, its peak is the highest peak in Africa, the top of which is covered with snow for a long time, and has long been known as "equatorial Snow Mountain". However, according to scientists, due to the rising temperature of the earth, the snow cover area of the peak in 2007 has been reduced by 85% compared with that in 1912. It is estimated that in another 20 years, the last miracle snow mountain on the earth's equator will disappear.

The dry climate caused bushfires in Australia.

Poyang Lake, Jiangxi, China. Affected by the rare low water level of the Yangtze River and the lack of rainfall in Jiangxi Province, Xingzi water area presents a picture of drought: the water level drops, the beaches are exposed, fishing boats are stranded on the lake beach and fishing nets are exposed.

In May 2010, oil pollution in the Gulf of Mexico was ignited. The ocean and the atmosphere share the consequences of oil pollution.

On May 5, 2010, in the Gulf of Mexico, the ship was operating in Louisiana. The oil pollution picture is "beautiful", but the consequences are bad.

A winding river in Leticia, Colombia. The undeveloped tropical rainforest is growing wantonly on the South American continent, where it is fortunate to maintain the original ecology and landform.
