... to highland ownership of respondents in two Grama Niladari Divisions, Pearson's chi square is shown 2.241 a value and 0.326 of variation. The number of d.f is 1 because, two Economical activities in lands should be identified to study environmental issues and related factors. It is shown in figure 1. The majority of respondent are involving with agriculture. Though they have governmental jobs, they do farming. Paddy cultivation and low country vegetable cultivation are main agricultural activities in the area. Tea, coconut and other export crop varieties are included to planting sector in the area. Agro chemical and fertilizer usage is common in the area. With the interviews of farmers, it was found that they need pesticides and chemical fertilizers for their paddy and vegetable cultivation. Chemical usage is traditionally accepted that directly affect to oil I the area. Figure 2 and 3 shows the pesticides and fertilizer usage of selected farmers. Chemical fertilizer usage into agricultural lands become a worldwide environmentally effective factor and it cause to make different type of environmental problems. Figure 1 shows the percentage of farmers that use chemical fertilizers into paddy lands. According to discussions with them, they use more organic fertilizers also. Higher usage of organic fertilizers may affect to environment than chemicals with increasing organic matters in the soil. Pesticide can be identified into three main types as insecticides, fungicides and herbicides. The community use tube wells, natural wells, streams and tap lines for obtain water. Waste water disposal may be affected to natural environment. Figure 4 shows the formation of waste water disposal in the ...

... For instance, pollution is a byproduct of human activity in the environment, with agricultural, water pollution, and air pollution serving as its primary causes. It is a natural or human-induced process that has an adverse influence on the ability of the land to take, store, and recycle water, energy, and nutrients in order for the ecosystem to function properly [11]. The study focused on effects of human activity on ecosystems and to evaluate how well managed protective areas contribute to habitat conservation. ...
Ecosystems encompass a dynamic web of interactions between living organisms and their environment. This network includes everything from the smallest microorganisms to the largest mammals, and landscape. Ecosystems provide vital services, such as clean air, water, nutrient, climate regulation and all the related things. However, human activities have significantly affected these systems, leading to habitat destruction, species extinction and disruption in delicate ecological balances. Human population growth increased the conversion of natural ecosystems for agricultural, industrial, and residential purposes, as well as the demand for ecosystem inputs like freshwater, fiber, and soil fertility. It also placed strain on the ability of natural ecosystems to sustain human populations. Growing agricultural, engaging in illicit fishing and hunting, and unplanned activities greatly influenced it. Future generations may face risk of starvation, thirst, illness, and catastrophe if we continue to lose biodiversity. It directly and indirectly contributes to many aspects of human life, such as security, the necessities for a happy life, health, positive social interactions, and the freedom to make decisions and take action. The article focused on effects of human activity on ecosystems and to evaluate how well managed processes contribute to habitat conservation, in order to better understand the importance of ecosystems on living beings in this planet.

... For example, pollution is a result of human activities in the environment and the main sources of pollution are farming, water pollution and air pollution (Owa, 2014). It is a human-induced or natural process which negatively affects the land to function effectively within an ecosystem by accepting, storing and recycling water, energy and nutrients (Chandralatha et al., 2016). ...
This study was proposed to explore the impact of human activities on the environment in Mhondongori. In this community, there are natural resources that include minerals, natural forest, wetlands, rivers and beautiful mountains. However, over the past two decades, the environmental quality of the community has deteriorated demonstrating irresponsible use of natural resources by humans. Indeed, if such poor natural resource management continues at the current rate, this would ultimately lead to extinction. Qualitative research design and convenience sampling methods were used. The study involved six participants who provided the data. An interview guide and observation techniques were used to collect data. Using content analysis data was classified into themes and a scorecard was used to determine the human activities on the environment and their impact. The results revealed that in Mhondongori, human activities that affected the environment were mining, veld fire, cutting down trees, overgrazing, excessive communal hunting and fishing, littering, water and air pollution. The impacts were the degradation of land, permanent scars on the landscape, deforestation, destruction of wildlife habitats, disappearance of wetlands, destruction of trees, grass, seed bank and seedlings, pollution of streets, bushes and rivers, disruption of migration and hibernation of animals. To conserve the environment, it was recommended that community leadership must develop appropriate environmental management strategies to mitigate these unfavourable impacts and that the state must empower Mhondongori leadership through reasonable legislative and other measures that would prevent environmental degradation.
