Guo Qiyu: A sandstorm swept across Beijing on March 15 morning, turning the sky yellow, limiting visibility to less than 1,000 meters and disrupting traffic.
Beijing Meteorological Service issued a yellow alert for a sandstorm at 7:25 a.m. on March 15, saying that Beijing is seeing increased levels of dust and visibility is expected to be less than 1,000 meters in most areas of the city until noon.

Light pollution is a growing problem in Germany. In many parts of Germany, lighting areas at night became larger and larger from 2012 to 2017. Only in eastern Germany illuminated areas remain at almost the same scale. Too much light at night can be dangerous to animals, stressful to people, and hindering astrophiles' ability to see the stars.

With Beijing's urban expansion, industrial development and population expansion, the rich surface water system has rapidly dried up, and groundwater has been seriously overdrawn, resulting in a situation of "all rivers are dry, all water is dirty", and the water shortage is gradually approaching.
It has been more than 30 years since the yongding River, Beijing's mother river, stopped flowing, and all 21 major rivers  which the city depends on have stopped flowing.

1.    The problem is taking place in Australia,between the South Pacific and Indian Oceans,with oceans all around the country.

2.    The problem is the rising of the sea level.

3.    The main causes are global warming,the air pollution and vegetarian destruction.

4.    It is affecting people’s lives.Some of the most pristine coastlines and symbolic beaches will probably be submerged.Houses and streets in the suburbs may be flooded,as well as some well-known tourist attractions.The houses’ prices decrease ten percent or more.The speed of sea level rising is fast and is quicker than the average rising speed of sea level.Furthermore,the coastal flooding has become more and more.

4.    It is affecting both people’s and animals’ lives.The days of extreme rainfall,desiccation and heat waves are increasing at a quick speed.Some species are affected too,like tunas’ habitats and food chains are seriously influenced,which impacts the whole food chain badly.Furthermore,here are two specific examples.Wellington will have a 30-fold increase in the number of fires a year,while Otago will have a 20-fold increase.

2.    The problem is that Beijing has serious haze.

3.    Automobile exhaust is the main source of pollution emission.Carbon dioxide, sulfide, dust and other pollutants are other sources of the pollution.Furthermore,the days of rainfall are few in Beijing,which increases the probability of haze’s appearance.

4.    It is affecting people’s lives,but it is getting better apparently.The haze is bad for people’s health,especially people’s lungs.That is why outdoor activities are easily canceled due to the haze.Secondly,haze is also a cause of cardiovascular disease.That is why it is impacting people’s lives deeply.

Problems: 1.The rise of sea level 2.The glaciers melting Main cause: Global Warming The emission of greenhouse gases such as CO2 and CH4. Industrial emission How can it affect human/animals’ lives: Maybe we can hardly realize the global warming’s influence. But in Antarctic, many animals such as penguins and Weddell seals are suffering from global warming. Global warming causes many problems to them. But we should care more about rise of sea level and glaciers melting. Their habitats are reducing. And more creatures’ appearance may cause biological invasion, which may threaten native species

# data[].attributes.body
Ziyue Zhang:  Haze is the one of the greatest problems that Beijing faces especially in winter because of consumption of coal. As a result of industrial consumption of coal central heating in winter, Beijing’s coal consumption is much higher than other seasons. In addition, there’s inversion which makes atmosphere stable. So the haze can be hardly disused

In the earlier stage of this month, we were really glad to welcome the first snow in Beijing, which is quite different from what it is in the past, as the first snow in Beijing falls on November 29th on average. This weird change is greatly related to the La Nino phenomenon. This occurs when the winter in China may come earlier and colder.

Andy: Frequent extreme weather in the low-lying coastal countries like Indonesia and Philippines. The threat of climate change is increasing, and it is increasing rapidly. “With many low-lying coastal cities exposed to sea-level rise and tropical cyclone risk, dramatic increases in heat and humidity are expected across the region, and therefore Southeast Asian societies and economies will be increasingly vulnerable without adaptation and mitigation. Known as “rain bombs”, heavy rain events will intensify by seven per cent for each degree of global warming.

Andy: Rising sea levels in Philippines. Nineteen of the 25 cities most exposed to a one-metre sea-level rise are in Asia, seven in the Philippines alone. But sea levels could rise by much more — up to 15 metres by some estimates — if the polar ice sheets melt, a catastrophic climatic phenomenon known as a tipping point, which will set off a domino effect of other climate events. sea levels are rising faster than elsewhere, and shorelines are retreating in coastal areas where 450 million people live. Rising waters are projected to cost Asia’s major cities billions in damage this decade, according to a recent study, and the impact is amplified by tectonic shifts and the effects of groundwater withdrawal, Horton told Eco-Business.

Junlao Mao: At the same time, with the global warming, the rise of ocean temperature and the expansion of seawater volume, the continental glaciers in Antarctica and Greenland will also accelerate the melting, resulting in the rise of sea level and inundation of coastal low-altitude areas.

One of the most significant environmental problems in Beijing is the terrible smog in the winter. The main cause for this problem is that with the fast development of the economic,there are more and more cars and the emission of greenhouse gases has increased significantly.It sets a limitation to people’s daily activities when there is a heavy smog.And the huge cost of environmental governance has brought bad impact on economical development.

Favorable weather conditions for generating strong wind or strong wind, favorable distribution of sand and dust sources and favorable unstable air conditions are the main reasons for the formation of sandstorms or strong sandstorms.

In addition, the wind down Poles caused by water and power cut, affecting industrial and agricultural production. More importantly, the loss of human health.Endless Microorganisms like Bacteria, viruses, and fungi With the help of dust into the body with the breath, causing diseases. Over-exploitation of natural resources, over-deforestation and over-reclamation of land caused by population expansion are the main causes of frequent sandstorms.
