Where is loss of biodiversity happening
When we talk about pollution, we may think of car exhaust fumes billowing into the atmosphere, but biodiversity is not only affected by this type, it is also affected by noise pollution and light pollution. Soil pollution and changes in its uses due to activities such as deforestation have a negative impact on ecosystems and the species that make them up. They act as predators, compete for food, hybridise with native species, introduce parasites and diseases, etc.
The overexploitation of natural resources , that is, their consumption at a speed greater than that of their natural regeneration, has an obvious impact on the planet's flora and fauna. The loss of biodiversity over the last few centuries projection of the UN Environment Program. Biodiversity loss has many consequences, not only for the environment, but also for human beings at the economic and health level. The alteration and destruction of habitats puts thousands of species in danger of extinction.
Biodiversity loss endangers human well-being by affecting soil and water, which are fundamental to food production. For example, imbalances in ecosystems can lead to the emergence of pests that damage crops. The capacity of forests and oceans to absorb CO 2 decreases if their ecosystems are adversely affected.
It is our responsibility to future generations". SDG 14 aims to sustainably manage and protect marine, coastal, terrestrial and inland freshwater ecosystems, address the effects of ocean acidification and regulate fishing while promoting sustainable fisheries.
SDG 15 seeks to protect, restore and promote the sustainable use of terrestrial ecosystems, sustainably manage forests, halt and reverse land degradation, combat desertification and stop biodiversity loss. Beyond UN commitments, we can all do our part to fight biodiversity loss on a personal level. By prioritising sustainable mobility and sustainable food , responsible consumption and recycling practices, reducing the small actions that pollute , helping to raise awareness of the smallest actions through environmental education , and ultimately supporting any action aimed at protecting biodiversity.

The most drastic and dramatic example is the loss of tropical rainforests. They are being destroyed fast. Loss of biodiversity definition is exemplified by the biodiversity decline in populations of migratory birds, mammals unique to a particular region, etc. Over-Exploitation: Natural resources which seemed infinite some thousand years ago now seem very much limited owing to the increased population of human beings alone.
Also, the greed of many human enterprises and endeavours over the past centuries has led to overexploitation of natural resources which in turn has led to the destruction of biodiversity. Species like Steller's sea cow and passenger pigeon have gone extinct in the last years because of overexploitation.
Land-use intensification has been one of the major causes of biodiversity and ecosystem loss. Thus, the above-mentioned habitat loss meaning is exemplified by the over-exploitation of the land resources.
Alien Species Invasion: Alien species for a particular region can be defined as the species that originally didn't inhabit the particular habitat or have not evolved in that particular habitat.
When a foreign species is introduced knowingly or unknowingly in a given region, it can turn invasive and cause biodiversity loss. Biodiversity depletion or biodiversity decline of more than species of cichlid fish in Lake Victoria of east Africa was caused due to the introduction of Nile perch.
Not only necessarily do the new species become invasive but also when they compete for the niche with the indigenous species and replace them, the entire ecosystem based upon and surrounding the indigenous ones suffers.
We are losing too many species that help offset our release of carbon dioxide into the atmosphere, exacerbating global warming in turn, while their presence would have helped stabilize temperatures by absorbing some CO2.
These impacts extend beyond just one region as trees provide shade which helps regulate water flow during dry seasons affecting rainfall patterns elsewhere, such as Central Africa, where we already see changes in temperature. An often overlooked impact of the loss of biodiversity, such as from climate change and habitat destruction, is a drastic decrease in economic productivity.
Climate impacts like severe drought or excessive flooding have also been shown to result in decreased agricultural production, which can lead to higher food prices for consumers worldwide — impacting their purchasing power while reducing available funds for other sectors within our economy like healthcare.
The ozone layer can be disrupted by increased levels of CO2 in the atmosphere. Scientists are exploring how biodiversity is worsening this problem and even what we should do about it. Biodiversity loss can contribute to a damaged ozone layer since it affects both plant life and pollution levels in the soil. The more diverse an ecosystem becomes- with more variation between each organism within its boundaries-, the less likely one type of living being will become so dominant as to create issues for other classes like polluting soils or consuming all available resources without any competition from others.
Acid rain is a natural consequence of the growing carbon dioxide emissions. The problem arises when these CO2s are released into the water that then leaves an acidic residue on land, which has been shown to cause plant death and soil erosion due to loss in biodiversity. Loss of biodiversity has been linked with the change in pH levels that cause acid rain. One of the most critical environmental changes caused by the loss of biodiversity is a global change in rock composition.
Researchers in New Zealand have noted a decline in biodiversity on the slopes and peaks. The loss is due to invasive species, including rats that feast on native bird populations.
