Try using some of these strategies:
When mowing, do not bag the clippings. Leave them on the ground instead or use a compost mower.
Put yard debris and vegetable matter back into the soil.
Start a compost pile. The decomposed matter that results is a very nutrient rich substance that can be used as fertilizer.
Use chipped yard waste as landscaping mulch.
Take waste to a composting facility (many communities have special pick-ups for this).
Some communities have leaf collection programs. Check into the services your community offers.
