Anything added into the environment that results in producing harmful or poisonous effect on living things is called pollution. Pollution is the process that makes nature’s resources such as land, water, air or other parts of the environment unsafe or unsuitable to use. Pollution can be of many types: soil, air, water, thermal, radioactive, noise, and light. The toxins released are inhaled by each one of us while we breathe.
Pollution and its Causes
Inhaling poisonous air is as hazardous as smoking. It is not only the humans who are affected from this polluted environment but also the animals. Air is filled with highly toxic gases. These dangerous gases in environment are released by the power industries that burn fossil fuels, industries that dispose wastes in the water, farmers using pesticides, high usage of artificial lights and loud sounds, etc. Each of these leads to generation of the life threatening cause – pollution.
Any use of natural resources at a rate higher than the nature’s capacity to restore itself can result in pollution of air, water, and land. Other than human activities, there are a few periodic natural cycles that also result in release of dangerous stuff. Natural activities other than the human activities like volcanic eruption, dust wildfires, etc also result in creation of pollution.
Globalization is another major cause of pollution. Globalization has become an effective facilitator of environmental degradation.
Conclusion
Every individual owns certain responsibility of maintaining few points such as not throwing garbage all around, growing trees, using public transport instead of their own, etc. We must shun excessive consumption and avoid careless and deliberate disposal of post-consumption waste resources which could otherwise be recycled and would led to pollution control.
Pollution cannot be reduced or controlled if a sense of responsibility towards our Mother Earth is not felt by all concerned.
The sentece that logically fits right before sentence 3 is "<em>While some programs focus on assisting those who are affected of bullying, others concentrate on changing the behaviour of the bullies</em>".
The reason behind this choice is that the sentence 2 introduces the idea of school programs to help stop bullying and this idea is developed in the sentence that has to be added before 3.
As regards the last question, your answer based should be based on your own experience. In case you have witnessed a bullying incident in school, your answer has to be affirmative. Otherwise, it should be negative.
