African elephants are becoming more endangered. That's according to a March 25 report by the International Union for Conservation of Nature (IUCN). The group determines how likely animals are to become extinct.

There are two species of African elephant. Savanna elephants roam grasslands. Forest elephants live in the woods.

Over the past 50 years, the savanna elephant population has fallen by 60%. The IUCN lists the animal as endangered. The forest elephant population has fallen by more than 86% over 31 years. These animals are critically endangered.

The last time the IUCN looked at African elephants was in 2008. Back then, they were listed as vulnerable. That's the category before endangered.

There are two main threats to elephants: poaching and habitat loss. Bruno Oberle is the IUCN director. He hopes the report inspires action. "Africa's elephants play key roles in ecosystems, economies, and in our collective imagination all over the world," Oberle says.

Welcome to Bamfield. It's a coastal village in British Columbia, Canada. Louis Druehl is steering The Kelp Express along the shore. For 51 years, the boat has taken him to Kelp Bay. There, ropes of seaweed grow beneath the water's surface.

DESIGN PICS/GETTY IMAGES

Druehl, 84, is known as the Kelp Grandfather. He began farming kelp, a brown seaweed, in 1982. Since then, he's studied it. He's cooked it. He's even written a book about it.

Over the years, Druehl has seen interest in seaweed rise and fall. But as climate change × climate change PAUL SOUDERS-GETTY IMAGES changes in the Earth's weather patterns (noun) The sea ice that polar bears hunt from is melting due to climate change. affects the planet, the world is turning to seaweed as a possible solution. "People have discovered seaweed," he told TIME. "They've discovered us."

Super Seaweed

Seaweed can play a huge role in fighting climate change. It is used to create natural fuel and renewable plastics. It helps marine ecosystems × ecosystem JAMESPHOTOGRAPHY.COM.AU-GETTY IMAGES the living and nonliving things that make up an environment and affect one another (noun) The rainforest's ecosystem includes many unique plants and animals. . And it absorbs carbon in the environment.

Some researchers say seaweed is a better climate-change solution than forests (see "Not Perfect"). Seaweed doesn't need fertilizers, fresh water, or land. And it grows fast. Katie Lebling is with the World Resources Institute. "When we're planting trees, we need to make sure it does not take away that land from food production," she says. "That is not an issue with seaweed."

Seaweed could become a global food source. Many worry about the environmental impact of eating meat. Could seaweed provide protein for the world? Carlos Duarte, a professor of ecology, thinks so. "To feed the world population by 2050, in a way that doesn't harm the environment, there is only one pathway," he says. "Seaweed farming."

New Opportunities

Global seaweed production has doubled in the past decade or so. Interest in seaweed as a food source and climate-change solution is booming. In British Columbia, this means job opportunities, including work for people from First Nations communities. They are among the indigenous, or native, people of Canada. Many have left the area to find work. "We want people to have a job, so that they can come home," Larry Johnson says. He's president of a group that works with First Nations communities.

For thousands of years, First Nations people have farmed on land and in the ocean. "Seaweed farming . . . helps us create economies of our own that align × align SIMA_HA-GETTY IMAGES to line up with; to side with (verb) Her feelings about poodles align with mine. with our traditions," Johnson says. "Our role has always been to connect with the land."

A seaweed industry could bring jobs to many people, such as those who lost work in the pandemic. Druehl's daughter is one. He wants her to come work in Kelp Bay. But even if she won't, lots of people are waiting to learn from the Kelp Grandfather.

Not Perfect

Seaweed might fight climate change. But there are risks. If it isn't harvested, it can rot and release carbon back into the water or air. Growing too much could also affect how much light reaches species living deeper in the water. That would be dangerous for underwater ecosystems.

Halley Froehlich works at the University of California, Santa Barbara. She says seaweed "can be a part of the solution" to climate change, but it's not a perfect solution on its own.

On October 8, the United Nations (U.N.) issued a warning: The worst effects of climate change could come sooner than expected.

A U.N. panel of scientists says the Earth has warmed by 1.8°F since the 1850s. The temperature could rise another .9° by 2040. That tiny increase would expose tens of millions more people worldwide to dangerous weather: heat waves, wildfire, food and water shortages, and coastal flooding. Entire ecosystems could be wiped out.

"For some people, this is a life-or-death situation," says Natalie Mahowald. She is one of the 91 scientists from 40 countries who worked on the U.N. report.

The scientists urge world leaders to act. To prevent this warming, carbon dioxide pollution would have to drop by 45% in the next 12 years. Governments could set a limit on carbon emissions × emission BYOUNGJOO-ISTOCK/GETTY IMAGES something given off (as a gas, for instance) (noun) We could always tell Mom's car by the white cloud of emissions from the tailpipe. or tax industries that pollute.

The report also says burning coal for energy would have to stop almost completely by 2050. Use of wind and solar power would need to increase.

Humans impact the physical environment in many ways: pollution, burning fossil fuels, deforestation, and more. Changes like these have triggered climate change, soil erosion, poor air quality, mass extinction, and undrinkable water, among other effects. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
