What is Environmental Activism?

More and more people are starting to realize that humanity has to change and take action to stop climate change, so that future generations can still survive on earth – our home. 

Many are trying to live more sustainably individually. However, there are plenty of additional things you can do to fight climate change. And one of these things is environmental actvism.

Environmental activism involves the collaboration of different groups of individuals and organizations with the purpose of addressing environmental issues, such as climate change, resource depletion, pollution, toxic waste, and deforestation.

Environmental activists identify issues that threaten the planet’s viability (from community to global concerns) and then develop strategies to promote awareness or produce solutions that directly address the problem.

The goal of environmental activism is to create a harmonious living environment that can be handed down from generation to generation without degrading in life quality due to poor human stewardship – thus, essentially a sustainable world.

Here are some of the best tips to become an activist!

In the following, you can find a list of the most famous environmental activists:

Top 10 Famous Environmental Activists

1. Greta Thunberg - Climate Activist

With growing news on climate change, the young generation is rising to speak up. Greta Thunberg has become one of the most famous environmental activists, despite her young age. She fearlessly challenges world leaders on climate change and political action. Her message has reached across the globe. 

Greta’s activism began in her home country: Sweden. She has challenged her parents and convinced them to make sustainable changes and swaps to reduce their carbon footprint. Later on, this led to demonstrations such as the ‘School strike for climate.’ At just 15, she striked school on Fridays, and protested outside the Swedish Parliament as a demonstration for action to curb climate change. This encouraged other students and young people to demand changes in their respective communities, which ultimately led to the founding of the FridaysForFuture (FFF) movement.

Greta has given several speeches and held protests as a call for change. In 2019 at the World Economic Forum, she delivered a speech that highlighted the fact that “our house is on fire.” People know Greta for her straightforward manner in delivering her messages. The U.S. House Select Committee on the Climate Crisis and the United Nations Climate Conference has also given her audience. 

Her undying passion for creating awareness about the climate crisis has seen many young environmentalists come up (like Luisa Neubauer, head of FFF Germany) and spread this gospel even more. Ultimately, people like Greta are showing how important sustainability education is for the long-term protection of our environment.

2. Wangari Muta Maathai - Environmental Activist

Wangari Muta Maathai - one of the most famous environmental activists

Wangari Muta Maathai (1940-2011) was an environmental, social and political activist from Kenya. She made history as the first woman in Central and East Africa to earn a doctoral degree

After her biology studies in the US, she returned to her home country to tackle environmental and women’s rights issues. Her dedication to women’s empowerment led to her active role in the National Council of Women of Kenya. During her time here, she conceived the idea of planting trees and having a positve human environment interaction. Although this had environmental benefits, Wangari also saw this service as a way to empower women. 

The tree-planting initiative later developed into the Green Belt Movement, which she founded. This grassroots organization was committed to planting trees in Kenya as a way to tackle the problem of deforestation. By the early 21st century, they have already planted over 30 million trees, provided jobs, and secured firewood for rural communities. The Green Belt movement empowered Kenyan women to be involved in this process while drawing income to improve their quality of life. It spread across countries in Africa and now works on grassroots, national and international levels. Globally, people recognize Wangari for her resilience and persistence in fighting for environmental preservation and human rights. 

Maathai was elected to parliament with 98% of the vote, and appointed Assistant Minister in the Ministry for Environment and Natural Resources. Finally, she became the first African woman to receive the Nobel Peace Prize in 2004. She was both, one of the most famous environmental activists, and an intellectual who contributed to the body of work in ecology, gender, and African studies.

3. Paul Watson - Conservation Activist

Paul Franklin Watson is a Canadian marine wildlife conservation and a famous environmental activist, who founded the Sea Shepherd Conservation Society, an anti-poaching and direct action group focused on marine conservation activism.

Watson exhibited an early affinity for protecting wildlife. At age nine he would seek out and destroy leghold traps that were set by beaver hunters, interfere with deer and duck hunters, and foil the attempts of other young boys to shoot birds.

Watson was an early member of Greenpeace International. During his years with the organization, he often employed daring and innovative tactics to defend wildlife from hunters, such as positioning his inflatable Zodiac boat between a pod of whales and the harpoon of a large Soviet whaling vessel, or forcing sealing ships to a halt by standing on the ice in their path. He also was known to handcuff himself to a pile of seal pelts being hoisted up onto a sealing vessel. Because of conflicts concerning such unconventional protest methods, Watson left Greenpeace, and established the Sea Shepherd Conservation Society in 1977. This organozation frequently undertakes dangerous expeditions to protect and defend marine wildlife from illegal poaching. This is usually done by actively hindering and even fighting or attacking whalers at open sea.

Watson shared his passion for animals and the environment through his involvement with numerous other organizations, including Defenders of Wildlife, Friends of the Wolf, Fund for Animals, the Royal Society for the Protection of Animals, and the Sierra Club, of which he was director.

For his efforts on behalf of wildlife, Watson was granted the Genesis Award, the George H.W. Bush Daily Point of Light Award, and enrollment in the U.S. Animal Rights Hall of Fame. All of these accomplishments and his contiuous drive & ambition are making Paul Watson one of the most famous environmental activists of our time.

Julia Hill, who people popularly refer to as Julia “Butterfly” Hill, is one of the most dedicated environmental leaders of this time. In a protest against the cutting down of a 1500-year-old Californian redwood tree, Julia lived in it for 738 days. The Pacific Lumber Company was set to cut down the tree, but Julia’s action showed her stance against tree logging. 

Her actions garnered media attention and also highlighted the destructive consequences of unsustainable actions. Julia’s commitment to environmental preservation charged up after a near-death experience. She had an epiphany and later joined the environmental movement in the fight for the protection of natural habitats and saving the planet. Her dedicated protest garnered attention around the role forests play in our world. 

The conservation group, Earth First!, supported Julia’s efforts as they provided her with supplies. After spending over two years living in the tree, the Pacific Lumber Company settled to preserve it and its immediate surroundings. Julia and her supporters had raised $50,000 during the cause and decided to donate it to the company to compensate them for lost revenue. Later, the company agreed to donate the money to Humboldt State University to support its sustainable forest research. 

Julia has written several books, including “The Legacy of Luna: The Story of a Tree, a Woman, and the Struggle to Save the Redwoods” and “One Makes the Difference: Inspiring Actions That Change Our World.” 

Nowadays, her way of protesting against logging is used by many other young activists who live in trees to prevent forests from being cut down. For example, in order to hinder the expansion of a coal mine and the associated logging of the Hambach Forest in Germany, climate activists are living in trees so that logging is prevented.
