Plant a Garden
You’d be surprised what a little patch of green space can do for the environment, and if you have a bit of land that you can turn into a garden, you’ll make more of an impact in your corner of the planet than you realise. Planting and harvesting your own food means that less has to be carted in from other countries, which decreases the amount of fuel that’ll be shot off into the atmosphere. If instead of food you’d like a flower and herb garden, plant flowers that attract and feed pollinators like bees, butterflies, and birds: they’re disappearing at an alarming rate because of pesticide and insecticide use, so an organic garden full of delicious blossom and seeding plants (like sunflowers, amaranth, and millet) will help exponentially.

If you don’t have your own land but have a thoroughly green thumb, consider getting involved in a community garden project: you’ll help others to develop their gardening skills, help to empower them by showing them how to be self-sufficient with their food security, and that garden will become a supportive ecosystem to all kinds of insects and small animals.
