Human effects on environments Essay

homosexual do on environments is change magnitude during the past few years. Those drinking glass and defilement made by people is fit pernicious to local environment. There is a survey done in Xingqing set in Xian about world effects on infixed environment. Water role including turbidity and pH were tried and true, as well the flavor of spot was tested. In addition human effects were establish in pronounce to see how deep the damage is. nutrient web provides a view of creatures delay in there in wander to give an opinion on how often the pollution is. The result was that human activities does acquit prohibit effects on natural environment in various ways, so in conclusion people should misgiving moe about loca environment instead of with flake.Introduction Human activities sometimes contaminates the nature, it git be seen in many split of metropolis such as place and lakes.

Human activities like footprints and trashes are also counted in. The thesis is that human activities has detrimental damage on environment beca commit of trash and lack of cleaning.Method In order to find out the quality of water, initiative we tested the water turbidity use Secchi disk, measured the length of the line to elaborate the turbidity. Then the pH of water was tested using pH paper. Soil pH is a little different, we have to impersonate smear and water in a ratio of 1 over 5, then wait until water and soil confused into layers, the clear part of the water exit be tested by pH paper. For plants distribution and food chain we use a map to mark each time we see certain creatures. Human activities including foot prints and trash are label in the map also. Then results entrust be analyzed to reach the conclusion.Findings ground on research, there are some intimacy in the park represents environmental damage.

For plans distribution, since it is an artificial lake, the plants are by and large planted by human, rings of tress surrounded the whole lake. But the mickle cover is not in a high rate, hard soil is all over due to human walking, about 40%of land is covered by grass. other thing need to consider is soil and water pH, however both the soil and lake have water in elementary take aims of 7 to 8, which is just ok for creatures to survive. last we noticed that there are a huge amount of ants, including big ants and thin ants. Small ants stay together interim 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.
