Public health issues

Species extinction / Deforestation



key issues

  • artificial light can confuse noncturnal animals and animals which hunt at night or rely on the stars for navigation
  • humans produce to much artificial light
  • the light interferes with natural cycles of light and darkness in the environment
Noise pollution
  • excessive noises can interfere with animal communication
  • can harm animals that rely on sound for hunting and navigation
  • humans produce excessive amounts of loud noises
  • including industrial and vehicle sources
Light pollution
  • water can cause many diseases
  • we can't drink it anymore
  • toxins from industrial and human waste are introduced into our water supplies
Water pollution
  • polluted air can cause many diseases in humans and animals
  • chemicals realesed into the air trough harmful gases, burning of fuels and other byproducts of human live
Air pollution


  • Human population continues to grow
  • at the beginning of the 20th century with 1.6 billion people
  • right now, about 7.5 billion
  • estimates put us at nearly 10 billion by 2050
  • growing global populations, combined with growing affluence, putting greater pressure on essential natural resources, like water
  • most growth is happening in Africa and in southern and eastern Asia


Top ten health concerns:

  • medical issue that affects a significant portion of a specific population

Public health issues

  • wild animals are hunted to extinction for bushmeat, ivory or "medical" products
  • At sea, huge industrial fishing boats clean out entire fish populations
  • loss and destruction of habitat are also major factors
  • Red List of threatened and endangered species continues to grow
  • wild forests get destroyed, especially in the tropics
  • 7.3 million hectares of forest are destroyed each year
  • tropical forests used to cover 15 percent of the planet's land area, now down to 6 or 7 percent
  • destroyed to make way for soybean/palm oil plantations, or other agricultural monocultures

Species extinction/Deforestation

  • take public transport
  • turn the lights of when leaving a room
  • recycle paper plastic, metal and organic materials
  • walk or ride a bike when possible
  • stop/don't start smoking
  • protect natural areas
  • much more

What can we do?

In conclusion I can say that I think it is very important for us to start talking more about environmental problems in school and in generell. We all have to do something to help our planet and stop destroying it.


Thank you for you Attention :)
