Question of the Week: What’s the best thing you ever did to protect the environment?

Each week we ask a question related to the environment. Please let us know your thoughts as comments. Feel free to respond to earlier comments or post new ideas. Previous questions.

Each of us – at home, at work, or at play – affects the environment in different ways and as such, we do different things to help protect it or reduce pollution.
