Question

write an article for the human impact on the environment

Answer 1

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. Modifying the environment to fit the needs of society is causing severe effects, which become worse as the problem of human overpopulation continues.Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include human reproduction, overconsumption, overexploitation, pollution, and deforestation, to name but a few. Some of the problems, including global warming and biodiversity loss pose an existential risk to the human race,and overpopulation causes those problems.

The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution emissions that are produced from human activity but also applies broadly to all major human impacts on the environment.

HEY MATE!!! ❤❤❤HERE'S UR ANSWER!!! ❤❤




Everything that humans do has some impact on the environment. Pollution is a result of human activities in the environment. The main sources of pollution are farming, water pollution and air pollution.

Farming is having an increased impact on the environment. This is because there is increased pressure on farmers to produce a single crop and to concentrate on one form of animal husbandry, such as, dairy cattle or pig breeding. This is more economical because better use can be made of equipment and organizations such as supermarkets have fewer farmers to negotiate purchases with. Also transport is much easier so produce can be easily moved to more destinations.


Pests are organisms that damage or destroy crops and livestock. There are different types of chemical pesticides for killing different types of pest. Insecticides kill insect pests, herbicides kill weeds and fungicides kill disease- causing fungi. Biodegradable pesticides are broken down by the activities of organisms and only remain in the environment for short time after they are applied. Non-biodegradable pesticides cannot be broken down by organisms and remain in the environment for long periods. Bioaccumulation of non-biodegradable pesticides happens in food chains and webs.

Some modern farming practices are damaging the environment and the destruction of habitats reduces the diversity of ecosystems, making them less stable and farming less sustainable. A balance is needed between increasing food production and the need for conserving the environment. Alternative strategies need to be used in order to achieve this. If organic fertilizers are used too much little humus is added to the soil, they damage communities of microorganisms involved in decomposition and the nitrogen cycle, it damages soil structure leading to increased erosion and it increases the risk of eutrophication due to run off. Organic fertilizers such as manure avoid these problems. SO THE NEED IS TO USE SUCH MORE AND MORE METHODS TO EFFECTIVELY EARN PROFIT BUT IN A RIGHT WAY, A WAY IN WHICH THERE SHOULD BE CONCERN ABOUT THE NATURE.
