Human effects on environments Essay

Human effects on environments is increasing during the past few years. Those frill and pollution made by people is becoming detrimental to topical anesthetic environment. There is a survey done in Xingqing lay in Xian about human beings effects on natural environment. Water tint including turbidity and pH were tested, also the quality of country was tested. In do- easilyer human effects were found in order to see how blockheaded the damage is. Food web provides a view of creatures live in on that point in order to give an opinion on how more than the pollution is. The result was that human activities does have negative effects on natural environment in various ways, so in polish people should cargon moe about loca environment instead of through trash. inlet Human activities sometimes contaminates the nature, it can be seen in many separate of city such as parks and lakes. Here the environment of Xingqing park is damaged by people for many years. As a park, it locates in th e center of the city which means the majority of people come there frequently. In order to influence the damage, items such as pH, turbidity and others were tested to find out how much the negative effects be. Human activities interchangeable hind endprints and trashes atomic number 18 also counted in. The thesis is that human activities has detrimental damage on environment because of trash and lack of cleaning.Method In order to find out the quality of piddle, first we tested the water turbidity using Secchi disk, measured the length of the line to calculate the turbidity. Then the pH of water was tested using pH paper. Soil pH is a little(a) different, we have to put soil and water in a proportionality of 1 over 5, then wait until water and soil marooned into layers, the clear part of the water go away be tested by pH paper. For plants distribution and food chain we use a subprogram to mark every time we see certain creatures. Human activities including foot prints an d trash are marked in the map also. Then results will be analyzed to reach the conclusion.Findings Based on research, there are some social function in the park represents environmental damage. Walking around the lake there is died look for over the corner spreads smelly smell, it seems that the quality of water is non good enough to support such tremendous creatures. Also there are not enough decomposers to break it down. In addition, there are some(prenominal) 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 massive of bacteria on the surface of water floating around,which is disgusting.On the ground there is a wild crab found in the bush, also there are wild sparrows and magpies found in the tree but not so many. For plans distribution, since it is an artificial lake, the plants are mostly planted by human, rings of kink surrounded the whole lake. But the grass cover is not in a high rate, hard soil is everywhere due to human walking, about 40%of land is covered by grass.Another thing need to consider is soil and water pH, however both the soil and lake have water in basic levels of 7 to 8, which is just ok for creatures to survive. Finally we noticed that there are a huge core of ants, including big ants and small ants. Small ants stay together meanwhile big ants going around alone. As internet shown the air quality is not as bad, pm2.5 is in a level of 110 in general.
