You're typing on your computer. Your computer uses electricity, which either comes from nuclear (waste), coal/gas (pollution), or hydroelectric (fish killer). It is also made of many non-recycleable materials, and contains mercury, which is a carcinogenic and seeps out of landfills into the groundwater after which humans and animals ingest it. It takes petroleum products to make plastic. P-tex is also plastic. The sport you enjoy doing is harmful to the environment. You also consume non-renewable petroleum products every time you drive to the ski hill.
In short, shut the fuck up and get off your preaching high horse, asshole.
