Carpool: reduces gas and energy waste that is expelled into the atmosphere

Reduce the use of plastic: plastic bags are made with oil so every time you use plastic bags at the grocery stop you use oil. Try a reusable tote bag or cloth bag 

Quit water bottles: instead, use metallic or reusable containers  

Use renewable energy: instead of having subsidized oil energy convert to renewable, possibly solar, energy

Buy organic fruit and vegetables: most freshly grown products are grown using fertilizers and pesticides, which use more oil than you think

Plant a garden: grass is not good for the environment because you have to cut t down; less grass space means less amount of using a lawnmower 

Use natural sent perfumes: some perfumes are made using petrochemicals which are bad for you and the environment. Instead, buy the ones that are made with natural scents and essential oils.

Use wood instead of plastic: wood is a natural material, while plastic is made from oils

Use less hair-dye: use an alternative to store bought hair color like henna, which is a plant based hair dye
