As for the questions Prof. Nicholson posted, I think that biggest environmental problem today is consumer waste. The amount of plastic used to package the simplest things, like toys or groceries for example is atrocious. Then, when you think about the products we buy that we dont even need, or gas that we guzzle and emit back into the atmosphere, its no wonder we're at an environmental crisis. The underlying problem is that we are all under the impression that what we do as individuals does not really affect the environment as a whole, when in truth, when we all think that way, we do irrevocable damage to our planet. This is why to live in an "environmentally friendly" is the key to making any type of improvement in our environment. This means to take active steps in reducing your ecological footprint: recycling, walking and watching "An Inconvenient Truth" lol. This is not only doing it yourself, but also encouraging others, especially in your household and immediate environment to participate as well.
