As we begin a new decade, we’re taking a look over the biggest environmental news stories since 2010. There’s a little good news, and a lot of not-so-good news. Still, we can look back and learn from what is happening in the hopes of taking action and restoring a brighter future for our planet.

Climate change moves into the mainstream, and more kids get involved

While a few climate deniers still fill high-ranking political posts, climate change is much more widely accepted as fact — rather than something to “believe in” — than it was in 2010. According to the TED blog, only four TED Talks specifically on climate change were posted in 2010 and 2011, although speakers mentioned the phenomenon. By 2015, TED said, people had shifted to seeing climate change as happening now, rather than in the far-off future, thanks to debates about whether or not places like the island nation of Kiribati were already sinking.

By the end of the decade, climate change is on the forefront of many people’s minds, especially young people. Worldwide movements like Extinction Rebellion use massive, nonviolent protests to urge politicians to slow the warming. Swedish teenager Greta Thunberg rose to international prominence, taking politicians to task about ignoring climate change and even being named Time Magazine’s person of the year in 2019.

Deepwater Horizon

The decade started with a tragic oil spill on April 20, 2010, one of the worst in history. The explosion on British Petroleum’s Deepwater Horizon, an oil rig operating in the Gulf of Mexico, killed 11 people. It leaked oil into the gulf for 87 days, for a total of 3.19 million barrels of crude oil polluting the coasts of Louisiana, Alabama, Mississippi and Florida. Images of people trying to wipe oil off pelican wings filled the news. Cleanup costs reached at least $65 billion. In addition to economic blows, especially to Louisiana’s shrimp and oyster industries, the animal death toll was high. According to the Center for Biological Diversity, about 82,000 birds, 6,165 sea turtles, 25,900 marine mammals and uncountable numbers of fish perished in the spill. Researchers are still gauging the long-term effects.

Extreme weather events become more frequent

As the National Oceanic and Atmospheric Administration warned, global warming escalates weather disasters. The last decade saw 111 climate-related natural disasters that each cost more than $1 billion in damage. These include tornadoes, hurricanes, wildfires, floods, drought, heatwaves and winter storms. In 2017, Hurricane Maria devastated Puerto Rico, killing 2,981 people and costing an estimated $93.6 billion in damages. Notable U.S. disasters included Hurricane Sandy in 2012 and the Missouri tornadoes of 2011.

Animal extinctions

Humans continued to edge out other animals in the struggle for habitat and resources. According to the World Wildlife Fund, species loss currently stands at between 1,000 and 10,000 times higher than the natural extinction rate, which is the rate Earth would lose species if humans didn’t exist. In 2012, Lonesome George, the last Pinta tortoise, died at over 100 years old. Formosan clouded leopards no longer slink across Taiwan. The Christmas Island pipistrelle, a microbat, has ceased its ultrasonic squeaking. No more baiji dolphins cavort in the Yangtze River. In this last decade, the planet also lost Caribbean monk seals, West African black rhinos, Madagascar hippopotami and Liverpool pigeons.

Rainforest deforestation

The decade’s final year witnessed much of the Amazonian rainforest go up in smoke. Brazil and Bolivia were particularly hit hard. Many attributed this tragedy at least in part to Brazilian President Jair Bolsonaro’s push for development over preservation. Horrifying photos from the National Institute for Space Research revealed enormous bald swaths where trees once stood. During its peak in August 2019, more than 70,000 individual fires were burning. The rainforest plays a critical role in regulating the entire world’s climate, so concerns stretched far beyond Brazil.

Increase in ocean plastic

During the last decade, plastic continued to fill the oceans. But awareness of ocean plastic also grew. A 2018 United Nations study reported that people dump approximately 13 million tons of plastic into the world’s oceans annually, and the researchers expected this number to grow. At the same time, many concerned citizens in cities around the world worked to decrease plastic waste by banning straws and plastic bags. Some hotel chains vowed to no longer stock beverages packaged in single-use plastic bottles. Many companies started developing products made from recycled plastic. Reusable water bottles became an important fashion accessory.

China stopped buying American recycling

Americans became more adept at recycling, but they weren’t necessarily aware where their recycled goods went. In 2018, China enacted a policy called National Sword. Suddenly, Americans realized their old plastic had largely been going to China, but China didn’t want it anymore. Now at the end of the decade, American cities are scrambling to save unprofitable recycling programs. Ironically, some cities have canceled these programs just when they’ve convinced people to recycle. Right now, it’s cheaper for American companies to produce new plastic than to recycle old. This is one of the many environmental problems that must be addressed in the coming decade.
