The hidden danger to wildlife can be linked to everyday imported consumer goods. Things such as an espresso coffee in Beijing, or a tofu salad in Chicago can now be pinpointed and measured, researchers said.

Doing the calculations based on huge amounts of data, researchers have found a global “threat map” detailing the impact on endangered animals of exports to the United States, China, Japan and the European Union.

To procure beans for that coffee or tofu, for example, forests have been cleared in Sumatra, Indonesia and in Brazil’s Mato Grosso, adding incrementally to the habitat loss driving dozens of animals and plants towards extinction.

The global supply chain of manufactured goods – from smartphones to chain furniture stores – can also contribute to wildlife decline.

Loss of habitat due to farming for things we love such as coffee may increase the extinction risk of endangered animals.

Focusing on nearly 7,000 land and marine species classified as threatened by the International Union for the Conservation of Nature (IUCN), the researchers traced “hotspots” of biodiversity loss to hundreds of commodities and their distant markets.

In earlier work, they concluded that 30% of worldwide species threats are due to international trade.

The new study, published in the journal Nature Ecology And Evolution, reveals which nations’ consumers drive species loss most.

It also suggests where conservation efforts should be focused.

Animal habitats destroyed

Currently, 90% of the more than US$6bil (RM27bil) mobilised each year for species conservation is spent within rich nations where money is raised.

“Yet these countries are rarely where threat hotspots lie,” said senior author Keiichiro Kanemoto, a professor at Shinshu University in Matsumoto, Japan.

The study provides tools to calculate what percentage of the species threat in one country is due to consumption of goods in another, he said.

About two per cent of the total threat to the endangered stub-footed toad in Brazil, for example, can be attributed directly to logging linked to goods exported to the US.

Timber harvested in Southeast Asia and exported mainly to the EU and China has similarly robbed the Asian elephant, the greater spotted eagle and the Sun bear of habitat.

And forests cleared in southern Brazil’s highlands for beef production encroaches on the woolly spider monkey, along with many other species.

Mass extinction event

“We identified biodiversity threat hotspots that are predominantly driven by just a small number of countries,” Kanemoto said.

“This should make it easier to initiate direct collaborations between producers and consumers.”

Finding new solutions for species loss has become urgent.

Earth has entered a “mass extinction event” in which animals and plants are disappearing up to 1,000 times more quickly than just a few centuries ago, according to scientists.

Mass extinction rates are worrying scientists and it does not help that it is linked to international trade.

There have only been six such wipeouts in the last half-billion years, some claiming up to 95% of all lifeforms.

Trade-related threats to wildlife can be indirect, and occur in unexpected places.

A large and growing demand for olive oil from Spain and Portugal, for example, could help push the endangered Iberian lynx into oblivion due to the construction of dams to control irrigation.

The calculations do not cover illegal trade in wildlife, such as ivory from elephant tusks or rare birds and reptiles sold as pets.

On paper, many threatened animals and plants are protected under the UN Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

But cross-border traffic, worth up to US$150 billion (RM670bil) a year, in these species – live or as body parts – remains brisk.

Nor do they take into account other factors such as urban sprawl, local hunting for food, or climate change.

The study found that trade-related threats are highly concentrated geographically, at both ends of trade routes.

For those driven by US consumption, for example, the five per cent of land area most affected accounts for nearly a quarter of the country’s total impact.

In the oceans, the five per cent of area most affected by US appetites includes more than 60% of threatened species habitats. – AFP Relaxnews
