Picnic this summer with reusable utensils, plates, cups, tablecloths and napkins.
Use "Reef-Safe" sunblock. Take a moment to "google" about the damage many sunblocks are doing to the coral reefs of the world and choose those that are safe to the environment, while protecting your skin.
Pull the window shades down on hot summer days to help keep your rooms cooler.
Bike rather than drive whenever reasonable.
Install a programmable thermostat and use "smart technology" to help you easily control your energy use, turning air conditioning off when you are out of the house.
Avoid toxic chemicals when repelling mosquitoes. There are natural products on the market. You can also try natural ingredients, such as lemon eucalyptus oil, cinnamon oil, citronella oil, and tea tree oil.
