Effects of human activities on Environment
1)Human beings form an integral part of the Environment and have the greatest ecological footprint, which has influenced Human evolution, from the very first Human ancestors to our modern-day selves.
2)Humans are a part of the Environment we live in, and our mostly well intended actions have far-reaching side Effects on the entire ecosystem and Environment.
Activities which have destroyed our Environment
The increasing Population
As the Human race, we have been affecting our Environment for thousands of years and this has been a topic of worry for scientists primarily because of the surpassing of the planet’s food supply. Accommodating the increasing population has been a major cause for much of the impact that we’ve had on our Environment.
Urbanization
Urbanisation refers to the increasing number of people who reside in cities. Urbanization has also contributed to a major transition and disparity in our ecological Environment. This is because urbanization requires large tracts of land to be deforested and then used for building cities.
Ozone Layer Depletion
An Ozone ring is formed by three oxygen atoms. While oxygen lends life to organisms, ozone is a toxic gas, which may be dangerous on Earth. Ozone plays a critical function in the various ambient layers of the atmosphere. UV rays, which are emitted by the sun, cause harm to animals, specifically skin cancer in Humans, hence they are harmful.
Deforestation and Reforestation
There has been massive deforestation to build homes for the people, which has resulted in significant negative effects on the Environment. Deforestation has many adverse Effects, including decreasing oxygen levels (and increasing greenhouse gases), elevated risk of soil erosion, and the destruction of animal habitats. However, the reforestation efforts seek to replace as much forest land as possible every year.
Pollution
A major life-threatening human activity that affects the Environment not only by contributing to air pollution, or water, or soil pollution but has also become a major threat for the entire Human species. It has also contributed to tremendous Effects on the world, leading to Environmental degradation and problems like acid rain and harmful algal blooms in the ocean.
Global Warming and Climate Change
Global warming refers to the rapid rise in Earth’s average surface temperature over the past century, mainly due to the greenhouse gasses released by people burning fossil fuels necessary for industrialization.
They are among the major challenges faced not only by the Environment but by the entire Human race as they are among the most dangerous activities that humans have affected the Environment. The release of Carbon dioxide contributes to the deterioration of the earth’s ozone layer, which in turn, contributes to global climate change.
Air Pollution
Overpopulation has caused a great deal of air pollution, especially due to the use of vehicles for transport. Harmful factory gases are released into the atmosphere, forcing us to breathe air that contains toxic substances and pollutants, which contribute to different medical conditions, including respiratory and cardiovascular disorders.
The exploitation of Marine Life
Our marine life is becoming endangered due to the massive scale of commercial fishing. Water degradation continues to hamper the lives of marine organisms and renders their longevity uncertain. In certain instances, when these fish are ingested by humans, it contributes to sickness and disease.
Habitat Loss
Wildlife conservation is becoming tougher because their natural habitat is constantly being threatened and destroyed. Water pollution and deforestation are the main reasons for habitat loss. Deforestation may give rise to abundant land for Humans but leaves animals homeless.
Extinction
Human Activities are triggering extinction on an unprecedented and mass scale. The destruction of natural habitats, Environmental hazards, global warming, poaching, pollution, and deforestation are some of the leading causes of this tragedy.
