Human activities have negative effect on plants and animal species. Some people think that it is too late to do anything about this problem. Other people believe that effective measures can be taken to improve this situation. Discuss both views and give your own opinion. as we all know, environment including plants and animals, has been substantially influenced by human activities and many measures have been taken to reduce bad impact and change current situation, however, is it necessary to take steps to improve surrounding or is it just a waste of time? there are different viewpoints. firstly, some people think that the damage on creatures is so serious that no cure for them. the reason of dinosaur dying off is due to human behaviour and it is obvious that this kind of animal could not survive again whatever effective contributions we make. on the other hand, plenty of people argued that it might be beneficial to earth to take measures and the results could be changed by effective steps. tkae water polluation for example, clearing and banning for pouring polluated water do change the current situation and improve the quality of water. in my own opinion, we should do action to change some consequences that could be improved, which base on the view of protecting current situation. in summry, it is suggested that human being should have subliminal thought of protecting envirionments and then we should take responsibity to improve surrounding as better as we can.
