nbsp; 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 ).
