Nature and technology have long had a complicated relationship. The factories of the Industrial Revolution set in motion the escalation of resource exploitation, pollution and greenhouse gas emissions that eventually led to the global climate change we face today. On the other hand, technological innovations such as hybrid cars and biodegradable packaging are making it possible for humanity to lessen its toll on the health of our planet.

Although nature and technology are often pitted as opposites — the past versus the future — in truth we don’t have to choose one or the other. In fact, to sustain life on this planet, both are crucial. That’s what makes Conservation International’s (CI) new collaboration with the Massachusetts Institute of Technology (MIT) so exciting.

Editor’s note: Last December, a scientific team began the rocky 36-hour boat journey from Puntarenas, Costa Rica, to one of the world’s best dive sites: Cocos Island National Park.

In a project developed jointly with the University of Costa Rica, 18 scientists specializing in diverse fields of marine biology made the trip as part of an ongoing effort to evaluate the health of the underwater ecosystems surrounding the island, a World Heritage Site that Conservation International (CI) has supported for 12 years.

Over the next week and a half, the team would log 310 dives — the equivalent of one diver spending more than 10 straight days underwater. Here are some highlights from the busy expedition.

Research goals

Our main objective was to assess the status of pelagic fish stocks — the species that spend most of their time far from coasts and the seafloor. Monitoring the health of the reefs surrounding the island was also a priority. CI and the University of Costa Rica created a baseline years ago; since then scientists have been assessing changes that have occurred in this natural laboratory and exploring the influence of different factors, such as El Niño, illegal fishing, climate change or the implementation of better protection measures within the park’s waters.

But our scientists weren’t just comparing the past with the present. They were also implementing new research experiments never before conducted in Cocos Island’s waters.

On the wall in Conservation International’s (CI) office in Paramaribo, Suriname, we recently installed a 1,000-day countdown clock. The clock ticks down toward the year 2020 — a big benchmark for many global environmental agreements that will impact the future of millions of people worldwide. Every day, this clock reminds our entire team that when it comes to protecting Suriname’s valuable forests and rivers and building a sustainable economy in what is called the “greenest country on Earth,” time is running out.

2020 is a milestone year for the Paris Agreement, when implementation of countries’ climate change action plans is set to ramp up. The Aichi Targets — a set of 20 biodiversity-related goals set in 2010 — also have a targeted 2020 due date. And one of the Sustainable Development Goals states that countries should manage their forests sustainably by 2020. If Suriname intends to meet the promised contributions to all these efforts, we have to make these 1,000 days count.

Editor’s note: Between now and March, Human Nature is exploring the complexities of living in, using and protecting one of the planet’s most valuable types of ecosystems — tropical forests — in a series we’re calling “No forests, no future.” This is the first post in this series.

If you have never visited it, the world’s most famous forest may inspire visions of dense, pristine forest, thundering waterfalls — and very few humans.

In fact, the Amazonia region — which encompasses parts of nine countries in South America and includes both the Amazon rainforest and the water-rich Guiana Shield — is home to 30 million people, including 375 indigenous groups. It contains the largest tropical forest in the world, the richest biodiversity on the planet, almost one-third of the world’s tropical forest carbon and one-fifth of the planet’s fresh water that flows into the ocean.

People near and far rely on Amazonia’s ecosystems for everything from climate regulation to fisheries and food security. But despite these crucial services, ongoing deforestation and climate change impacts threaten to permanently alter this massive system — drying it up, decimating its biodiversity and slowing the flow of benefits to its people to a trickle.

If we want to prevent irreversible damage, we must first figure out what parts of Amazonia we can’t afford to lose.

A species made famous by a series of hit animated films is now threatened with extinction after a dramatic drop in its wild population.

Two new independent studies estimate that there are only between 2,000 and 2,400 ring-tailed lemurs — perhaps the most charismatic of Madagascar’s animals, and a flagship species of the country — left in the wild. This is a 95% decrease from the year 2000, when the last known population estimate was published. It also means that now there are more ring-tailed lemurs in zoos around the world than remain in the wild.

Where does half your wild-caught seafood come from? The answer may surprise you

We live on land, but the oceans feed us: Seafood is consumed more than any other animal protein in the world — more than pork, chicken, beef or eggs. In fact, fisheries feed three out of seven people worldwide.

You’re likely picturing gigantic commercial fishing vessels pulling in millions of pounds of fish with mechanized nets to meet this global demand. But the source of our seafood is much more varied — it depends on the millions of fishers that make up the community fisheries scattered across the world’s coasts.

Small-scale, artisanal fisheries support food security, livelihoods, economic development — even climate change solutions. Here are four things you might not know about them.

  1. Coastal community fisheries feed the world by providing 50% of global seafood catch.

Fish is the last major food source that humans collect from the wild — and the main protein source for 3 billion people. And half of the wild-caught fish people eat comes from coastal community fisheries. Making sure that these fisheries are sustainable is critical to the environment and to ocean-dependent communities — which is ultimately good for productivity. Because coastal community fisheries often use less harmful techniques than commercial fisheries, and because many fishers live close to the waters they fish in, fishers are motivated to protect and sustainably manage the waters to ensure fish health and availability. Healthy waters, thriving ecosystems, fishing practices that allow fish to reproduce and create more fish — these sustainable practices all help coastal community fisheries provide half the world’s seafood catch.

Editor’s note: In the tiny Southeast Asian country of Timor-Leste, Conservation International (CI) and the University of Adelaide recently carried out a short survey to expand scientific knowledge of the range and abundance of whales and dolphins in the waters around the island nation. The survey’s results, which CI marine mammal expert Olive Andrews shares below, will help inform the management of these species. 

Flying into the Timorese capital of Dili, I looked expectantly down into the vast blue of the Ombai Strait. In just one more sleep we would be on a boat searching the area for the largest creatures on our planet — blue whales — and their close relatives.

Editor’s note: News about conservation and the environment is made every day, but some of it can fly under the radar. In this occasional series, Human Nature shares three recent stories of interest in our world. 

  1. 2017: Agriculture begins to tackle its role in climate change

The story: For the first time in international climate discussions, agriculture is appearing front and center in countries’ plans to cut carbon emissions and curb climate change. Previously, countries’ emissions reductions plans focused on areas such as clean energy and transportation. But at the 2015 climate talks in Paris, according to InsideClimate News, “nearly 80 percent of the countries said they would use agricultural practices to curb climate change, and more than 90 percent said they would use those practices in addition to changes in forestry and land use linked to farming.”

What’s next: Agriculture has emerged as a critical sector within which each country can — and must — take immediate climate change action. The article suggests this is because agriculture is “existentially linked to a country’s very survival and increasingly under threat from weather extremes, drought and floods.”

Many sustainable farming practices, such as growing more crops on existing land to reduce the need for further deforestation, can support both climate change adaptation and mitigation goals. Crucially, changes to agriculture that have climate change benefits can also benefit farmers by increasing yields. Continue reading

The world’s largest ivory market will soon be shut down, according to the Chinese government.

Last week, China announced plans to phase out its domestic ivory market by the end of 2017 — a major development acknowledging the growing threat poaching poses to Africa’s dwindling elephant population, which has been cut in half in only 25 years.

Editor’s note: As the end of 2016 approaches, Human Nature is revisiting some of our favorite stories of the year. To support crucial conservation work like this, consider making a donation to Conservation International.

Some of the world’s most iconic photos are famous for capturing a fleeting moment and infusing it with meaning. But photos can have another power, too: revealing the difference between what was and what is.

This year, Conservation International sent photographer Jessica Scranton back to the Green Wall project in Indonesia’s Gunung Gede-Pangrango National Park, four years after her first shoot there, to document the changes in the landscape — and people’s lives.

See what she found for yourself in this photo essay.
