Thomas Bogle has worked in the footwear industry for years. He also loves torun. He runs every day in the forest near his home in Colorado. But while training fora race， he couldn’t stop thinking about the bits of plastic and rubber1 that his shoeswere shedding2 on the forest floor.

With every step we take， our shoes leave behind an invisible3 trail4 ofcontaminants5. These contaminants can potentially6 harm the soil， water andanimal health.

Shoes contain different types of plastics. Every year， about 500，000 tons ofmicroplastics seep7 into the world’s oceans. Microplastics are tiny pieces of plastic.They form as larger plastic objects break down. They can harm living things and theenvironment.

Bogle is trying to do something. He wants to change the way that shoes are made.

托馬斯·博格爾在制鞋行業(yè)工作多年。他也喜歡跑步。他每天都在科羅拉多州他家附近的森林里跑步。但在為一項(xiàng)比賽進(jìn)行訓(xùn)練時(shí)，他不由自主地想到了他的鞋子在森林地面上脫落的塑料和橡膠碎片。

我們每走一步，鞋子都會(huì)留下一條看不見(jiàn)的污染物痕跡。這些污染物可能會(huì)對(duì)土壤、水和動(dòng)物健康造成潛在危害。

鞋子含有不同類(lèi)型的塑料。每年，約有50 萬(wàn)噸微塑料滲入世界海洋。微塑料是微小的塑料片。它們是在較大的塑料物體分解時(shí)形成的。它們會(huì)危害生物和環(huán)境。

博格爾正在努力做點(diǎn)什么。他想改變鞋子的制造方式。

Waste Problem With Sneakers

Some shoe brands are trying to developgreener shoes. For example， some shoebrands have changed the materials in theupper sections of shoes.

But many brands have largelyoverlooked soles8. A sole is the bottom part ofa shoe. It is made up of the insole， whichtouches the bottom of your foot， and theoutsole， which makes direct contact with theground when you walk.

Now， several companies are starting todevelop plant-based soles. They don’t leaveplastics behind when they break down.

Shoes are designed to last 1，000 years， andwe use them for 100 days， said Yuly Fuentes-Medel. She helped write a report on how tomake the shoe industry more sustainable9.

運(yùn)動(dòng)鞋的浪費(fèi)問(wèn)題

一些鞋履品牌正在嘗試開(kāi)發(fā)更環(huán)保的鞋子。例如，一些鞋履品牌已經(jīng)更換了鞋面的材料。

但許多品牌在很大程度上忽視了鞋底。鞋底是鞋的底部。它由鞋墊和外底組成，鞋墊接觸你的腳底，外底在你走路時(shí)與地面直接接觸。

現(xiàn)在，幾家公司開(kāi)始開(kāi)發(fā)植物鞋底。它們分解時(shí)不會(huì)留下塑料。

“鞋子被設(shè)計(jì)成可以持久使用1000 年，而我們使用100天?！庇壤じ欢魈厮?梅德?tīng)栒f(shuō)。她幫忙寫(xiě)了一份關(guān)于如何使鞋業(yè)更具可持續(xù)性的報(bào)告。

Fixing Footwear

Americans alone throw away 300million pairs of shoes every year. Onlyabout 13 percent of clothing and footwear isrecycled in the United States.

That’s partly because of the complexity10 of the shoemaking process.The average sneaker is composed of morethan 130 individual pieces. That makes itnearly impossible to recycle them.

The plastics in shoes also causeproblems while people are wearing them.One study suggests that plastic from shoesoles reduces soil’s capacity11 to holdwater. Another study suggested that salmonwere dying due to a chemical that is foundin both tires and footwear.

Plant-based soles can solve some of theproblems. They won’t shed plastic into theenvironment. Plus， they generate fewer toxic12 chemicals. But shoes made withnatural materials face some of the samechallenges as plastic-based shoes once they’rethrown out. Taking the shoes apart is stillhard. Recycling shoes will require setting upnew systems.

But Fuentes-Medel said it’s importantthat people continue to ask for theseplant-based products. She said thesystems for recycling will fall intoplace. This could lead to a moresustainable shoe industry.

處理鞋類(lèi)

僅美國(guó)人每年就扔掉3 億雙鞋。在美國(guó)，只有大約13%的服裝和鞋類(lèi)被回收利用。

這在一定程度上是因?yàn)橹菩^(guò)程的復(fù)雜性。普通的運(yùn)動(dòng)鞋由130 多個(gè)單件組成。這使得回收利用它們幾乎不可能。

當(dāng)人們穿著鞋子時(shí)，鞋子里的塑料也會(huì)引起問(wèn)題。一項(xiàng)研究表明，鞋底的塑料會(huì)降低土壤的蓄水能力。另一項(xiàng)研究表明，三文魚(yú)正因一種存在于輪胎和鞋類(lèi)中的化學(xué)物質(zhì)而死亡。

植物鞋底能解決其中一些問(wèn)題。它們不會(huì)將塑料脫落到環(huán)境中。此外，它們產(chǎn)生的有毒化學(xué)物質(zhì)更少。但是，用天然材料制成的鞋子一旦被扔掉，就會(huì)面臨與塑料鞋相同的挑戰(zhàn)。拆開(kāi)這雙鞋仍然很難?；厥招有枰⑿碌南到y(tǒng)。

但富恩特斯-梅德?tīng)柋硎?，人們繼續(xù)要求這些植物性產(chǎn)品是很重要的。她說(shuō)，回收系統(tǒng)會(huì)到位。這將使制鞋業(yè)更具可持續(xù)性。

Sustainable Soles

Bogle had an idea to create an entirelyplastic-free shoe outsole. He got some helpfrom Gene Kelly. He is a professor of soilscience and a fellow runner. Together，Bogle and Kelly developed a shoe sole. Itis made of beeswax13， vegetable oils andplant products such as leaves and husks14from corn and other crops.

Bogle’s company partners with farmers.The farmers grow and harvest the plantmaterials. Then， the materials are blended15with natural rubber to create the sole.

These shoes don’t shed toxicchemicals. Instead， the soles put nutrients16back into the soil as they naturally weardown over time.

These days， Bogle runs， hikes and golfs inshoes with his company’s plant-based soles.

“Footwear is a very hard product tofix，”he said. “It really requires completelychanging how we think about footwearand how we make footwear and thematerials we use.”

環(huán)保鞋底

博格爾有創(chuàng)造一種完全不含塑料的鞋外底的想法。他得到了吉恩·凱利的幫助。吉恩·凱利是土壤科學(xué)的教授，也是一名跑步愛(ài)好者。博格爾和凱利共同開(kāi)發(fā)了一款鞋底。它由蜂蠟、植物油和諸如玉米和其他作物的葉子和外殼的植物產(chǎn)品制成。

博格爾的公司與農(nóng)民合作。農(nóng)民種植和收割植物材料。然后，這些材料與天然橡膠混合被制成鞋底。

這些鞋子不會(huì)釋放有毒化學(xué)物質(zhì)。相反，隨著時(shí)間的推移，鞋底會(huì)自然磨損，從而將營(yíng)養(yǎng)物質(zhì)重新注入土壤。

現(xiàn)在，博格爾穿著他公司植物鞋底的鞋子跑步、遠(yuǎn)足和打高爾夫球。
