Human effects on environments Essay

human beings race set up on environss is increasing during the past few years. Those put away and pollution made by mountain is becoming detrimental to topical anaesthetic milieu. There is a survey through in Xingqing park in Xian close human effects on internal environment. Water case including turbidity and pH were tried and true, as well the quality of soil was tested. In addition human effects were free-base in order to consider how involved the damage is. Food web provides a view of creatures live in on that point in order to give an scene on how much the pollution is. The end point was that human activities does have negative effects on natural environment in various ways, so in oddment people should c be moe ab pop unwrap loca environment instead of through trash.Introduction gay activities sometimes contaminates the nature, it can be seen in many break downs of city much(prenominal) as parks and lakes. Here the environment of Xingqing park is damaged by people for many years. As a park, it locates in the center of the city which means the absolute majority of people come in that respect frequently. In order to find the damage, items such as pH, turbidity and others were tested to find out how much the negative effects are. Human activities like footprints and trashes are also counted in. The thesis is that human activities has detrimental damage on environment because of trash and lack of cleaning. regularity In order to find out the quality of wet system, first we tested the wet turbidity using Secchi criminal record, measured the distance of the line to calculate the turbidity. Then the pH of wet was tested using pH paper. Soil pH is a bitty different, we have to put soil and water in a ratio of 1 over 5, then wait until water and soil separated into layers, the clear part of the water will be tested by pH paper. For plants distribution and nutrition chain we use a be to mark every time we see certain creatures. H uman activities including foot prints and trash are marked in the lay out also. Then results will be canvas to reach the conclusion.Findings Based on research, thither are something in the park represents environmental damage. Walking around the lake there is died look for over the recessional spreads smelly smell, it seems that the quality of water is non good adequacy to support such big creatures. alike there are not plentiful decomposers to break it down. In addition, there are several insects float on the water, also some trash such as plastic bags are around corner of the lake edge. The water turbidity is 33cm in Secchi disk measurement, another thing is seen commonly is great of bacteria on the surface of water floating around,which is disgusting.On the ground there is a wild crab make up in the bush, also there are wild sparrows and magpies found in the tree diagram but not so many. For plans distribution, since it is an schmalzy lake, the plants are mostly plant ed by human, rings of tress surrounded the consentient lake. But the grass cover is not in a high rate, unvoiced soil is everywhere due to human walking, about 40%of land is cover by grass.Another thing destiny to consider is soil and water pH, yet both the soil and lake have water in basic levels of 7 to 8, which is salutary ok for creatures to survive. Finally we noticed that there are a huge sum of money of ants, including big ants and small ants. Small ants halt together meanwhile big ants deviation around alone. As internet shown the port quality is not as bad, pm2.5 is in a level of 110 in general.
