A healthy world needs both our daily actions and support from larger systems. I will spend 60 minutes learning about how I can use my investments and savings to advance environmental sustainability.

Synthetic clothing can contain plastic and shed harmful microplastics into our water. I will use a microplastics catcher in my laundry, or install a microplastics filter for my washing machine.

I will spend 30 minutes learning more about the importance of freshwater + ocean conservation, and how I can reduce my water use. I will share what I learn with people in person, on social media, and on the feed.

Itr's estimated over a billion water bottles are thrown away each year. Even if they were recycled, that still uses energy and resources from the earth. I will use a reusable bottle and stop purchasing bottled water, saving 2 disposable plastic bottle(s) a day.

Food in the landfill is one of the main sources of greenhouse gasses. I will avoid sending up to .69 lbs (.31 kg) of food waste to the landfill per day by composting my food.

Studies have shown that when we spend consistent time in nature, our health improves, our creativity increases, and our connection to the planet gets stronger. Each day of the Ecochallenge, I will spend 30 minutes outside (in a large or small patch of nature), then share my observations, reflections, and learnings on the feed.

Bees are vital to ecosystems. To help save the bees, I will learn which local flowers provide nectar and plant them in my backyard or in a pot on my balcony.

Plastic bags can be mistaken for food by many wild animals and can end up in habitats that harm wildlife. I will not accept any disposable bags when making purchases, including produce bags.

The world is full of unique species. I will spend 30 minutes each day learning what the native plants and wildlife are in my region.

Grass lawns are water-intensive and on average require about 30 percent of a household’s water consumption. Native plants are water-efficient and help maintain the balance and diversity of local ecosystems. I will plant native species with water-efficient plants to conserve water and improve the habitat, then post a photo on the feed to share.

Understanding cleaning product ingredients and their effect on water and biodiversity is helpful to our consumer choices. I will spend 5 minutes learning about how cleaning products affect our water and try making my own cleaning products to reduce pollutants.

Each of us has a water footprint, directly linked to our daily activities as well as the water required in the production of things we use each day. Understanding our water use is important for a healthy planet. I will calculate my water footprint and look for a few ways I can reduce consumption or waste, then share what I learned on the feed.

When we explore natural spaces around us, our connections with them change. I will spend 10 minutes exploring a new area around my neighborhood, office, or campus (e.g., park, water body, nearby trail, community garden, green space, etc.).

The waste we create daily can go unnoticed. I will track the waste I create in a day and post a photo log on the feed to see how much I create and where I can make different choices to reduce my waste going forward.

The impacts of our waste are far reaching. I will create zero waste for an entire day and share my reflections and learnings on the feed.

Energy use and waste is often invisible. I will complete an online energy audit of my home, office, or dorm room and identify my next steps for saving energy.

Carbon emissions can show up in many surprising ways in our life. I will calculate the carbon emissions associated with my household and consider how lifestyle changes could reduce the carbon footprint and impacts on the environment.
