pollution
most of us today (recognize that environmental pollution has
been　a greatly serious problem . lots of plants trees corps are
destroyed　by bad air .many fish die of poisonous water . thousands
of people die from eating poisoned fish or breathing in gas . therefore ,
environmental pollution should be responsible for these diseases
that are disabling ,or bringing death not only to human beings ,
but also to wild life .)
from above ,we can find that the reasons why (environment are polluted
more and more seriously) are as follows.
the primary reason ,I think , is (the reason of harmful substances into
environment . for example ,to prevent insects ,farmers make use of great
amounts of insecticides, so as to have bumper harvests . however ,they
pollute air ,water and land ).
second,(the gas coming from the car engines and factories also make
environment polluted badly ).
the third reason actually is (the result of a growing population in
the world . everyday , so much litter and waste are poured out from
houses ,also pollute the environment ).
the significance for (controlling pollution ) noted that it's high
time that more effective measures should be taken .
therefore ,(new laws should be passed to limit the amount of pollutants
from factories . moreover ,in the households ,there is an obvious need
to reduce litter and waste . let's make our good efforts ,and the world
will be a safer place to live for us ).
