If you have a garage filled with tools and other oddities, you can easily make it a little nicer for you and the environment. The next time you do some cleaning you can think about what is clean for the rest of the environment. Of course, you’re going to want to properly dispose of pesticides as you should never use them in the first place. There are more things you can do too, like checking your tools to find out if the tools can be replaced by something with a smaller carbon footprint.
After the leaf blower, you might want to check on your lawn mower, chainsaw, snow blower, air compressor, and generator, if you have them. The gasoline engines in these pieces of equipment spew out greenhouse gases that are as concerning as the crud coming out of leaf blowers.
As for alternatives, electric or manual gear is the way to go. There are plenty of lists online that can guide you towards the best push mower, battery-powered chainsaw, electric snow blower, air compressor, or electric generator. My town has been having a craze for robotic lawn mowers recently. They don’t work on hills, but if your lawn is flat, consider one of these electric models. They are mesmerizing to watch, cut the grass in a random pattern, and, bonus points, you don’t have to push them around.
