Just plant some trees, it's easy: - Gather seeds from native species in your area. - place 2-3 large seeds or 5-10 smaller seeds in a pot. I use old 1l milk containers. - Put the pots outside, a terrace or balcony will do. - As soon as the seeds sprout, find a spot to plant. Can be natural (prairie, forest, ..) or not (parks, roundabouts, parking lots, yards,medians,...). Just ask for permission if planting on private property. - Go back during dry spells or heatwaves and water them. - Profit?
