The alarming implication of these trends is that developing countries may become sick before they get rich. That sickness may, in turn, cripple health systems. The yearly healthcare costs in Southeast Asia from obesity-related complications like diabetes and cardiovascular disease are already as high as $10 billion. Such diseases are an added burden on countries already struggling to manage primary health care needs. Policies related to taxation, urban design, and education may help control obesity at a lower cost than eventual medical treatment for an increasingly overweight population. Some governments have already intervened to control obesity by implementing taxation on unhealthy foods and drinks. Thailand, Brunei, and Singapore have adopted the soda tax. South Africa is likely to introduce a sugar tax beginning in April 2018. The city of Berkeley in California recognizes that taxes alone are not enough to address obesity. The city’s sugar tax revenues are used to support child nutrition and community health programs. This underscores the importance of education.

There is also promise in many initiatives. Urban design holds significant power to reshape lifestyles and public health. Improving the attractiveness of public space can draw residents out of their cars and living rooms. A recent study of urban neighborhoods in Shanghai and Hangzhou found that residents living in more walkable neighborhoods enjoy better health than residents who lived in less walkable neighborhoods in urban China. Finally, healthier lifestyles begin in grocery store aisles. Governments should encourage tighter connections between agricultural production systems, urban grocers and food vendors. Such initiatives can also help urban residents better understand how food is sourced. This raises awareness about the relationship between natural foods and healthy lifestyles. Combining controls on unhealthy foods with policies that encourage healthy eating and active lifestyles can reduce obesity rates. Improving public health is an important policy developing countries should take from both an economic and social point of view. To quote the recent Global Nutrition Report, reducing obesity will boost global development.

数据显示，煤炭满足了全球大约30%的能源需求，提供了40%以上的电力。在人口第一和第二大国中国和印度，煤炭所满足的能源需求比例甚至高达70%左右。中国的煤炭消费量在去年已经下降，煤炭进口下滑了11%,这是十年来的首次下降。中国经济增速已经放缓，同时也做出极大努力削减煤炭使用以减少污染。由于燃煤发电厂没有满负荷运行，再加上煤炭供应充足，造成国际煤炭价格压低。煤出口价格从去年的峰值下跌了约60%。
