*The viewpoint of people that believe that Climate change is not real, like the United States president. His opinion influences a lot of people who support him and so people remain misinformed. Climate change is not an idea to be treated as 'belief' or not. It is a scientific fact which has been proven as the atmosphere deteriorates more and more, and the polar caps melt resulting in sea levels rising and possible floods.
*The viewpoint of people that don't care about throwing their gum on the floor and streets. This simple fact threatens the lives of birds since they think it is food and once they start pecking at it, the gum gets stuck to their beak and they are unable to eat or maintain their nests, therefore dying.
*The viewpoint that some companies possess which does not mind the environment or care for it at all. Some companies produce pollution that is harmful to the ozone layer and atmosphere, some are only concerned about their products,selling and their own benefits while leaving to the side, the effects that the company produces which damage the environment.
