We've depended on fossil fuels for hundreds of years, we rely on them for our energy, However; mining is known to cause severe environmental issues. One of many issues in burning fossil fuels is air pollution which causes both harmful effects on public heath and our environment.
Harmful carbon dioxide emissions contribute to global warming and climate change. Another problem which goes along with burning of fossil fuels in mining, coal espessially. Over the past few decades, underground coal mining has gradually shifted to surface minign in the U.S.
This employs highly invasive techniques such as area strip mining and mountaintop removal. Huge volumes of excess rock and soil are dumped into adjacent streams and valleys, altering the natural flow of streams and altering ecosystems.
A bio trans system collects and grinds leftovers into a homogeneous biomass. The food waste and vegetable or fruit peelings are directly emptied into the bio trans technology, and then converted into a homogeneous biomass. There's also minimal need for additional water, as the food contains most needed.
Solar powered cars depend on the weather, they use a renewable energy source which reduces air pollution. However; these cars would be very expensive.
With new technology like solar powered cars, and or hydro powered cars and bio trans technology to transition us from fossil fuels and polluting our air, to renewable resources, we could reduce our pollution on earth and slow down climate change by huge amount.
