Human beings can excercise a great infuence on the environment around them this can be both positive as well as negative however, in this question we will focus only on the positive impact. Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Humans impact the environment in several ways common effects include decreased water quality, increased pollution and greenhouse gas emissions, depletion of natural resources and contribution to global climate change some of these are the direct result of human activities, whereas others are.

Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence the human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions. Impact of human activity on the natural environment as global population grows it puts pressure on the environment leading to water shortages and pollution, deforestation and famine.
Human influences in the lower athabasca basin include the oil sands operations, pulp and paper mills, municipal discharges, and, to a lesser extent, forestry and agriculture some of the specific impacts on aquatic ecosystems related to these influences are discussed in the resources section.

In the interest of measuring the impact of human activity on the nitrogen cycle and ocean eutrophication, an international team of scientists looked at decades worth of ocean data they concluded that humans are responsible for half of the world's oceanic nitrogen fixation , as published in the journal science. In fact, we are having a profound impact on it indeed, our cleverness, our inventiveness and our activities are now the drivers of every global problem we face. Human activities have caused the percentage of carbon dioxide in the atmosphere to increase global warming extra carbon dioxide in the atmosphere increases the greenhouse effect. Having some trouble answering this scenario: 'a child shows your their passionfruit at lunch time and points that it has seeds' explain how you would assist children to learn about the impact of human activities on the environment.
As i discussed, the major cause of global warming is the human activities as the activities done by the humans have increased the level and impact of global warming which from past many decades was not a matter of concern as the emission of carbon dioxide was not to the extent of being a threat and whatever amount of gas was emitted was. A positive human impact on the environment occurs when a person takes action to improve society, nature and its resources acting positively, even in a small manner, has a major impact on the environment, especially when it is done consistently. Knowing that human activities are the main driver of global warming helps us understand how and why our climate is changing, and it clearly defines the problem as one that is within our power to address.
