解决气候危机可能是21世纪最重要的健康机遇之一!在本章中,我们将思考健康和气候变化是如何联系在一起的,以及为什么这一点很重要

室内空气污染与健康

你认为世界上有多少人通过直接燃烧木头、木炭、动物粪便或煤来做饭?


在室内使用这些燃料烹饪时产生的烟雾和煤烟会导致心脏和肺部疾病,以及癌症和中风。由于这些疾病,室内空气污染导致每年430万人早逝,这些主要发生在发展中国家,如下图所示

Many countries face a lot of death from indoor air pollution

These traditional cooking methods also contribute 2-5% of global annual greenhouse gas emissions.These are caused by burning the fuels and deforestation to gather them.

Improved cookstoves (either solar-powered or clean fuel-burning) can cut emissions by as much as 95% as well as saving lives: for example, it is estimated that 150 million clean cookstoves could help avoid 2.2 million early deaths in India.

There are even more benefits! Improved cookstoves use less fuel, which reduces the time people spend gathering firewood. This is a difficult, and sometimes dangerous, task.

室外空气污染

阻止室内空气污染并非全部。交通是户外 空气污染的主要来源, 2014年交通排放占全球温室气体排放量的16%。据估计,交通排放导致2015年38.5万人过早死亡

More use of public transport and electric cars are possible solutions.

More walking and cycling would be even better – these reduce emissions, improve local air quality and help prevent diseases related to inactive lifestyles.

Protecting Nature and Health

Cutting down trees not only results in carbon emissions, but can also lead to more disease outbreaks. How?

75% of new infectious diseases in humans come from animals.

Zoonoses are diseases that come from animals

When forests are cut down, and roads built within them, humans come into much closer contact with the animals that live there. This means that diseases are more likely to spread between them.

Deforestation can cause more disease outbreaks

防止森林砍伐可以减少未来疾病爆发的可能性,同时限制碳排放

And that’s not the only health reason for protecting nature. A growing body of evidence suggests that experiencing nature can have great benefits for our physical and mental wellbeing. Put simply, being around plants and animals makes us happy!

饮食与健康

We currently produce enough food to feed our global population, but this is not shared equally. 11% of the global population is undernourished which means they don’t have enough food to support a normal, healthy life. At the same time, 8% of global deaths were due to obesity in 2017.

造成肥胖的原因


Eating too much meat (particularly red and processed meats), processed food, and sugary drinks is leading to obesity as well as type 2 diabetes and some cancers.

Research suggests that healthier diets should include less processed food and meat.

Healthy diets save lives

结论

Healthier diets, clean cookstoves and transport choices are just three of the ways we can improve global health and slow climate change at the same time. Solutions that help people and the planet!
