Most human activities cause different kinds of pollution. Luckily,we have friends to help us fight a 1 pollution, and trees are one of them.Trees not only give us the oxygen we need to breathe, but they also fightagainst air pollution by directly r 2 dirty air and haze. To put it ...
上文"Trees bind the soil of the earth tightly. (树木紧紧地束缚着土壤。)"说明树木可以保护土壤,设空处承上启下,下文"They are highly beneficial for preventing soil erosion. (对防止水土流失极为有利。)"说明树木可以起到防止水土流失的作用。G项"因此,湍急的水流或强风无法带走土壤。"承上启下,符合...
15. Moreover, many of these expansions have caused forest loss3,13,14,16,17. These types of regional human activities in highlands diverge from the general view that the expanding agricultures or human settlements in hills and mountains are not economically feasible (see...
This is the first attempt to examine the long-term history of human impact on sediment yields from a karat catchment using depression deposits. This work improves our understanding of the influence of human activities on soil loss at a depression-catchment scale, and of the evolution and ...
Human activities, such as heavy industry, sewage irrigation, and fertilizer application, have led to severe soil pollution of HMs [203]. The remediation methods for soil polluted with HMs can be mainly divided into physical, chemical, and biological remediation [45]. Physical remediation, including...
Human activities in the environment interfere with the planet's natural balance, making the Earth's climate less stable and predictable. Climate change brings abnormal occurrences such as unprecedented flooding; increased numbers of storms, hurricanes and typhoons; fiercer brush fires; and most notably...
The impact of human activities is also marked on the neighbouring slopes, which were progressively cleared: the soil is exposed to erosion and landslides occurs (Gue´lat 1994). After about 700 cal BC, hydrological activity decreases and sedimentation occurs at a slower rate. In some places, ...
These chemicals have intensive use in agricultural and industrial activities, so they emerge across the world, including the deserted plateau and the polar zone [106]. The organochlorine chlorothalonil is a fungicide that has arisen in seawater and air in the Arctic as well as in snow cores in...
The study area is the mountainous region, and the mountainous region has a rich source of metals and minerals. The mountain of Gwaldai area has 80% Pb, Bajaur Agency Has 35% Mn and Ushiri Valley has 16% Cu and mining activities are under processing which is the main cause of HMs. ...
Control over pollution and all kinds of destroying activities like deforesting and poaching is the most important. 12.It seems that we are exploiting nature by using up all its resources. What shall human beings do presently when we are facing the shortage of natural resources? We should seek...
