The world is using a lot of energy, mainly from burning fossil fuels, which creates a lot of greenhouse gases (GHG). The increased GHG levels are making climate change worse, causing things like floods and droughts. In 2015, a global agreement was made to reduce GHG emissions to stop the Earth from getting too warm (global warming). Using biofuels made from plants instead of fossil fuels can help cut down on GHG emissions, which is important to protect our planet.
