Biodiversity Loss Could Be Making Us Sick — Here’s Why

到2050年,70% of the world’s population预计将住在城镇和城市。城市生活带来了许多福利,但全球城市居民正在看到一个rapid increase在非传染性健康问题中,如哮喘和炎症性肠病。

一些科学家现在认为这与之相关biodiversity loss, the ongoing depletion of the varied forms of life on Earth. The rate at which different species go extinct is currently a thousand times higher than thehistorical background rate

微生物多样性是丢失的生物多样性的一大部分。和这些微生物 - 细菌,病毒和真菌,其中 - 是essentialfor maintaining healthy ecosystems. Because humans are a part of these ecosystems, our health also suffers when they vanish or when barriers reduce our exposure to them.

The Inner Ecosystem of Our Bodies

我们的肠道,皮肤和航空公司港口不同的微生物,这是不同环境中存在的巨大微生物网络。188bet滚球投注单独的人肠哈福100 trillion microbes,超过我们自己的human cells. Our microbes provide services that are integral to our survival, such as processing food and providing chemicals that支持大脑功能

与我们环境中不同范围的微生物联系也是因为润滑我们的免疫系统也必不可少。188bet滚球投注在更接近我们进化的环境中发现的微生物188bet滚球投注(如林地和草原)被称为“老朋友“一些微生物学家的微生物。这是因为他们在“教育“我们的免疫系统。

Part of our immune system is fast-acting and non-specific, which means it attacks all substances in the absence of proper regulation. Old friend microbes from our environment helpprovide this regulatory role。它们还可以刺激有助于控制炎症并防止我们的身体攻击我们自己的细胞,或诸如花粉和灰尘之类的无害物质的化学物质。

城市Lacking Biodiversity

Exposure to a diverse range of microbes allows our bodies to mount an effective defensive response against pathogens. Another part of our immune system produces tiny armies of “memory cells” that maintain a record of all the pathogens our bodies encounter. This enables arapid and effective在未来对类似病原体的免疫应答。

We need to get serious about the urban microbiome: Restoring natural habitats can help increase biodiversity and the health of city residents.

To help fight infectious diseases like COVID-19, we need healthy immune systems. But this is impossible without support from diverse microbiomes. Just as microbes have important roles in ecosystems, by helping plants grow and recycling soil nutrients, they also provide our bodies with营养素和health-sustaining chemicals thatpromote good physical and mental health。This strengthens our resilience when facing diseases and other stressful times in our lives.

但我们的城市往往缺乏生物多样性。我们大多数人都为灰色空间交换了绿色和蓝色空间 - 混凝土丛林。因此,城市居民暴露于促进健康微生物的多样性。污染也会影响城市微生物组。空气污染物可以alter pollen因此,它更有可能导致过敏反应。

救生鸟的问题

救生恐惧症,所有微生物都不糟糕的感知,通过鼓励我们许多人对我们家中的所有表面进行消毒,常常阻止儿童走向外面并在污垢中灭亡并在污垢中进行消毒。土壤是最多的土壤biodiverse habitats on Earth,所以城市生活方式可以通过切断这种重要的联系来真正缺乏年轻人。

People living in more deprived urban areas have poorer health,较短的寿命期望和higher rates of infections. It’s no coincidence that these communities often lack accessible,high-quality green and blue spaces。They’re also less likely to have access toaffordable fruit and vegetables

What Can We Do?

We need to get serious about the urban microbiome. Restoring natural habitats can help increase biodiversity and the health of city residents.Growing more diverse native plants,营造安全,包容性和无障碍的绿色空间,可重新播放市中心,郊区公园可以恢复城市生活中的微生物多样性。

Our research正在帮助城市设计师恢复能够促进健康互动的城市的栖息地between residents and environmental microbes。但是必须改善使用这些绿色和蓝色空间,以及价格实惠的营养。支持分配和社区花园could provide free, nutritious food and exposure to helpful microbes in one fell swoop, while sessions that teach people how to grow their own foodcould be prescribed由健康专业人士。

促进与大自然的联系 - 包括我们目前避免的许多人的微生物 - 应该是任何大流行后恢复策略的关键部分。我们必须保护和促进对我们个人和行星健康至关重要的无形生物多样性。
