All the ecological state of our Earth is related to all of our activities.
Healthy lifestyle - it's not at all mean that you are running every day at 6 kilometers in the morning.
That you go to the gym every day and just moving weights.
That you are a vegetarian (which also is not healthy)
Even is it that you do not smoke (it is the hardened Smokers have reached the limit of 120 years)
And a lot of other healthy lifestyle propagandize and usage.
Not healthy is it already then when your workout clothes out at the natural seam, or use chemical dyes for clothes. When your household goods from non-natural materials.
And most importantly, you purchase them - and part of, tomorrow throw - not only in the factory that made it polluted nature, but you do it as a user pollute nature, and not doing sparingly with everything.
