It is my aim to discuss human language within

Air pollution is caused by humans. Smog and ozone layer depletion are two major causes. They are both toxics in the air that humans create and toxics that effect humans as well. Smog is caused by so many different chemicals that ranges from things like automobile exhaust to hairspray. It affects humans mainly in the circulatory and respiratory systems which are both very important and crucial to survive. Ozone layer depletion is a very serious decline of gas in the ozone layer which is bad because

are curvature movements caused by differential or unequal growth in plant organs‚ which results in their bending in the direction of a particular stimuli‚ for instance light. Such movements which are induced by external stimuli are called trophic movements. A trophic movement of plant organs in response to the source of light is known as Phototropism. The stem grows towards the direction of light‚ and is therefore said to exhibit positive phototropism. For instance‚ we have observed that shoot apices
