Future of planet earth

• Non-renewable energy:

  • oil
  • coal
  • nuclear
  • natural gas
• renewable energy:

  • wind
  • hydropower
  • solar
  • biomass
  • geothermal
• Fracking pro:

  • creating jobs
  • fracking is manageable
  • chemicals which are used are harmless in large dilution
• fracking con:

  • natural gas is a fossil fuel and therefore harmful to the climate
  • during fracking, cracks in rock layers can also be blown up
  • large amount of water for agriculture is missing
• pro Vegetarismus:

  • its healthier
  • better for the environment
  • less meat production, less animals that threaten badly
• vegetarianism con:

  • missing important proteins (B12)
  • exotic fruits have to be flight in from other countries (co2 emissions)
• e-fuels pro:

  • Acceptance from society
  • no additional greenhouse gases
  • e-fuels can be easily stored and transported over long distances without any energy loss
• E-fuel con:

  • high cost of production
  • production requires a significant amount of renewable energy
  • energy is weather dependent
• E-fuel, short for electronic fuel, refers to a type of synthetic fuel produced using renewable energy sources, such as wind or solar power
• global warming: gradual heating of Earths surface mainly caused by human activities releasing greenhouse gases into the atmosphere
• GM foods (pro):

  • you could feed more people particularly in developing countries, could also improve food issues in developed countries
  • GM plants can be made resistant to drought, heat, pests, weeds, diseases so it protects the environment (use less pesticides and herbicides) and also less crops will be lost
• GM foods (con):

  • Ethical considerations related to manipulating the genetic makeup of organisms
  • Potential unintended consequences in ecosystems
• Climate change: increasing changes in the measures of climate over a long period of time (temperasures, wind)
• Fossil fuel (oil, gas, coal):

  • sustainability ranking: low
  • pro: cheap, easy to get
  • con: not renewable, influence to climate change
• nuclear power:

  • sustainability ranking: moderate
  • pro: get a lot of energy, no green house gases
  • con: nuclear waste, high percentage of risks
• biomass:

  • sustainability ranking: moderate
  • pro: its renewable using, not that chemical
  • con: stinks
• Solar Energy:

  • sustainability ranking: high
  • pro: renewable energy, less emission
  • con: expensive to build, dependent on the weather
• Wind energy:

  • sustainability ranking: high
  • pro: renewable, no risk for people
  • con: very loud, need wind to work
• Water power (hydro energy/tidal energy):

  • sustainability ranking: moderate to high
  • pro: can control it
  • con: expensive, limited, stole life space from people/animals
