Biosolids are a class of fertilizers and composts made from treated sewage sludge.  It has been shown that biosolids contain heavy metals and other toxic chemicals, yet these make their way onto crops year after year.  There is not enough evidence to suggest that biosolids pose a hazard to humans, but there has not been enough research either.  The lack of evidence doesn’t necessarily mean that there isn’t a problem, but the EPA hasn’t learned this yet in science class.

A carbon footprint measures the amount of CO2 produced annually from our daily activities (from burning fuels). The average North American's carbon footprint is 20.12(tons of C02 emissions a year). This means that every American would have to plant 29 trees a year to balance out their strain on the environment! Luckily there are endless and surprisingly simple ways to minimize our negative effects on the environment. Tackle the list or decide which options can easily be adjusted to fit into your lifestyle.
