Your decision to change for the greener does make a difference. But be patient with the results. Even though your actions may not transform the world overnight, you do have an impact on the environment with every choice you make. When you buy organic and non-toxic products, you are voting with your money. When you blog about endangered animals and what people can do to help protect them, you give voices to those who have none. When you carpool to work, you inspire others to follow in your carbon-lighter footsteps.
