Biofuels are renewable energy sources derived from organic matter, known as biomass, which can include plants, agricultural residues, and waste materials. They serve as alternatives to fossil fuels, potentially reducing greenhouse gas emissions and reliance on non-renewable resources. Biofuels can be classified mainly into two categories: first-generation and second-generation biofuels, based on their feedstock sources and production processes.
The gig economy refers to a labor market characterized by short-term, flexible jobs, often mediated by digital platforms or applications. This economic model allows individuals to work as independent contractors or freelancers rather than as traditional employees, offering a degree of autonomy in choosing their work hours and tasks.
Deep ecology is an environmental philosophy that advocates for the intrinsic value of all living beings and the natural world, irrespective of their utility to human beings. This ideology believes in a fundamental shift in the way humans perceive and interact with nature, emphasizing a more profound relationship between humans and their environment. Developed in the 1970s by philosopher Arne Naess, deep ecology argues for a holistic approach to environmental issues, moving beyond the anthropocentric viewpoint that places human needs and desires at the center of environmental decision-making.
