Every day we hear saddening news from all around the world regarding the progressing environmental damage. There are fewer and fewer intact, wild places on Earth where nature remained without being affected by human activities.
In this world of galloping globalisation, it is extremely difficult for most people to lead slow, balanced lives. Many of us find it hard even to follow up with our closest family, so no wonder that saving the world from global warming or preventing biodiversity losses get put aside.
At the same time, we feel more needy (and capable) of making our travelling dreams come true. Sustainable tourism is widely encouraged these days and in many places we can find and join the initiatives that support local communities or protect natural heritage. But the question of transport isn’t actually discussed – we keep driving and flying on traditional fossil fuels. And what if we care about the environment during our journeys and want to keep the planet healthy?
It is estimated that planes produce gigatonnes of CO2 along with sulphur and other greenhouse gases. But using boats, buses, or cars instead doesn’t sound neither like a practical nor a planet-saving option. Even electric cars, if we give them a closer look, don’t provide a green transporting solution.
Alternative fuels are an option worth exploring. Scientists are testing various cutting-edge technologies that can turn into fuel various ingredients including coffee or soybeans, natural oils, wood, algae, or even animal feces, waste, and food leftovers.
However, obtaining these kinds of biodegradable fuels isn’t an easy task. Most biofuels available nowadays are either low in efficiency or require activities often considered to be non eco-friendly or simply not worth it. Their production and processing may involve deforestation, greenhouse gases emissions, or highly energy-consuming machinery. In the long run, these might cause soil and water pollution, affect food supplies, or lead to biodegradation.
Despite the existence of all the challenges related to the alternative fuel sources, we should still know that more sustainable ways of driving and flying are possible. By being aware of the renewable alternatives, we can start the debate and that’s the first step to improvement!
