In this day and age, keeping a low carbon footprint has grown in popularity at a rapid pace. Everything from water conservation to renewable energy has become a hot topic among the public. While some of the ways to live a greener life are fairly obvious, there are some that people may not think about on a regular basis.

According to the Chicago Tribune, one of the best ways to live an environmentally-friendly lifestyle is to switch an exercise routine from inside to outdoors. Treadmills and other high-powered machines require a decent amount of electricity to function. The source recommends those who prefer to work indoors to try to enjoy the summer weather and hit the streets for their workouts.

Another way to get greener is by cutting down on using plastic bottles for water. There are a variety of options available such as using portable, reusable containers, or, for those who prefer filtered water, to purchasing an at-home water-filtering system.

A Chicago-based company recently started making environmentally friendly water bottles. The bottles are 100 percent plant-based and were created after the owner discovered that 40 million water bottles were being tossed into landfills on a daily basis, according to the source.
