text: The idea I feel that has most significantly changed people's lives in the 20th century is that of caring for the environment.  Today, people have become aware of the importance of environment to our future.
  	People are concerned with nuclear weapons.  We realize that countries that which have many weapons have the power to destroy the world.  Also related to this topic is nuclear waste.  Nuclear waste is not only harmful to humans;  it also kills animals and plants.  We are now fighting for acts to clean up our lakes and rivers.  Companies are no longer able to freely dump their wastes w/o being heavily fined.
  	People have also become concerned with nature.  We used to assume our natural resources were never ending.  Now, though, we realize what we use, needs to be replaced.  For example deforestation is a very big issue, many groups have formed to plant more trees.  We also realize our fossil fuels need to be used more conservatively.
  	Another important topic we are all aware of is recycling.  This links 2 issues, one of not producing much nonbiodegradable products and the other of reusing what we have.  (Recycling in a small way also helps those w/o homes b/c they receive money for their collections).  Many countries realize that recycling is not only beneficial to their economy it also is beneficial to their environment.
  	 Another important issue is that of conserving energy.  In the past, once again, we assumed our energy was never ending.  Now though people are more inclined to turn off their lights when they're not in their rooms, to not leave taps running and basically not to waste our natural resources.  We realize that conserving is not beneficial to our environment but it is also saves money.
  	We have also become more considerable of our animal life.  We are no longer able to kill animals freely.  We do still raise some for food but hunting is limited and we are all aware of the possibilities of extinction.  One realizes that animals have rights too.
  	In conclusion, the idea of caring for the environment is still a new one.  We are slowly becoming more aware and are beginning to take more precautions.  The ideas above are just a few of the topics we are now concerned with.  But we are heading in the right direction and hopeful by the 21st century we will have fixed everything we have destroyed!
