All over the world, more than 2 million children and teens are participating in classroom walkouts in an effort to bring attention to the severity of climate change. Called, Fridays for the Future, leaders of the movement are gaining traction, and have developed a declaration that emphasizes their demand that world leaders do something to stop the rising global temperature. This movement was sparked by Sweden’s Greta Thunberg, who, at 16-years old, has started this movement, spoken to global leaders, and continues to do what’s needed to demand action in the face of climate change.

For one family, living plastic-free was a lifestyle decision made after they learned more about the harm that plastic waste causes. The Watt family lives as plastic-free as possible – carrying their own utensils, buying in bulk and bringing their own glass containers, making their own household cleaner, and using reusable beeswax wraps instead of cling wrap. While these are all steps in the right direction toward reducing the nearly 335 million tons of plastic produced every year, experts say we need to rely less on individual actions and push for tougher laws and systemic changes.

What started as a far-out concept in Berkeley, California, the goal of becoming zero-waste has spread to cities across the world. The idea makes individuals, communities, and governments think differently about what they do with their garbage and take responsibility for their environments.

Philadelphia’s West Laurel Hill Cemetery has gone green. While the burial business may be notoriously filled with chemicals, this cemetery has introduced 50 different sustainability initiatives, including banning machinery use, only allowing biodegradable caskets – or no caskets at all – and keeping the grounds flourishing with native plants instead of manicured lawns. The efforts also include community engagement to bring residents into the environmental shift as part of a larger, cultural trend toward sustainability.
