Human Impact on Biodiversity

Many people are unconcerned about the environmental damage they are making. However, it is critical for humans to recognize their impact on biodiversity since without it, humanity would not exist. If nothing changes in the way humans consume resources on Earth, biodiversity will continue to deteriorate until human life can no longer be sustained. Human population density, land use, and cultures all have an effect on nature, resulting in habitat destruction for many species. Humans must recognize how human actions are affecting biodiversity and the responsibility to protect what biodiversity remains on the planet. The human species will be capable of supporting life on Earth for longer thanks to adequate education and demands that governments adopt decisions to protect biodiversity.

Human Activities That Affect Biodiversity

Humanity has a variety of deliberate and unintentional effects on the planet’s biodiversity. To date, the greatest threat to biodiversity has been how humans have modified natural environments to make room for crops or natural wealth, but as climate change intensifies, ecosystems will be increasingly impacted. Land use change (mainly primarily large-scale food production) is the primary direct source of biodiversity loss, accounting for roughly 30% of global biodiversity reduction. Unsustainability (overfishing, overhunting, and overexploitation) for food, medicine, and timber is the second component, accounting for around 20% of the total. Changing climate is the third most important primary job of biodiversity loss, accounting for 14% of total loss along with pollution. Invasive alien species make about 11% of the total.

Climate change, according to some projections, will become the dominant cause of biodiversity loss in the next decades. All of the big factors of biodiversity loss are intensifying, and as a result, the rate of species extinction is quickening.

Because of rising demand for natural resources as a result of rising human population, rising per capita consumption, and shifting consumption patterns, more natural environments are being used for agricultural, mining, industrial infrastructure, and urban areas. Human activity in key areas that cause biodiversity loss include:

• Deforestation: tropical rainforests are very rich in species and are rapidly disappearing.
• Habitat loss as a result of widespread, incremental encroachment, such as that produced by urban sprawl
• Pollution levels related with widespread pesticide usage and fertilizer misuse are 6 and 12 times higher than they were in 1961, respectively.
• Agriculture is thought to be a hazard to half of the endangered species.
• Dams and irrigation have reduced water flows in several of the world’s greatest water catchments.
• Hunting and over-exploitation of species, such as in wild-catch fisheries, but also in the wildlife trade, are examples.
• Invasive species and illnesses are spread through trade and travel.
• Warming and shifting rainfall patterns caused by climate change modify species distributions and the underlying heat and water processes that determine present ecosystems.
• Plastic trash pollution, albeit its long-term consequences on biodiversity are unknown.

Human Biodiversity Definition

Biodiversity is a term that refers to both the variety of life on Earth and the simplest form that it produces. Genetics, natural phenomena, and human impact all contributed to it. Biodiversity encompasses gene variety within a species, species diversity within ecosystems, and ecological diversity across the planet. Biodiversity is determined by a number of elements that differ in terms of regional and temporal variation.

Although many people are unaware of how essential diversification is to themselves, it is apparent that humanity would not be capable of surviving without it. Every day, people use 40,000 species, the most of which go undiscovered. Even though only a small percentage of people understand it, biodiversity supplies humans access food, water, oxygen, energy, waste detoxification, climate stabilization, medicine, recreational and tourism opportunities, and many other benefits. Simply said, without biodiversity, there would be no human population.

How to Determine Impact? 

Although there is no definite way of estimating the whole influence of people on biodiversity, it is clear that many of their behaviors are causing biodiversity to decline. The area of constructive land and water required to produce the item being consumed, and there is a need to compensate for the waste produced by humanity, must all be taken into account so according to management and construction practices in use in order to decide the overall impact that humans have on a given environment.

Human actions, whether direct or indirect, have resulted in a loss of biodiversity. Human drivers are both secondary and direct, according to the Convention on Biological Diversity. Economic, commercial, sociopolitical, technology and science, as well as cultural and religious variables, are some of the direct human drivers. Depending on local land use patterns, wildlife introductions and removals, climatic variables, exploitation, water contamination, and global warming are all direct human drivers.

Conclusion 

Because biodiversity is a problem that affects everyone, anyone should be conscious of the impact on it. Human survival odds are decreasing as the earth’s biodiversity declines. As a result, it is critical to educate the masses on how to live in harmony with the environment. It’s also crucial to ensure that the government passes rules that protect biodiversity in the long run rather than focusing on short-term profits. If humans go extinct, it will very certainly be due to their own actions or inaction. Humans will hopefully recognize that it may already be too late.
