Over-population and development are posing the biggest threat to biodiversity in the Southern Cape Sunday, 19 July 2020, 07:56 . Gabrielle_Phinney. The biggest driver of biodiversity loss is ‘land-use change’: specifically, converting and managing wild land for agriculture and development. In the process of habitat degradation, the organisms that were once living in a particular area or region are displaced and are forced to relocate; thus resulting in biodiversity reduction. Across the board, changes in land and sea use account for the largest portion of loss, making up 50% of recorded threats to biodiversity on average. This Ecuadorian Became A Spider Scientist! The habitat can no longer accommodate and support the life of the organisms present, thereby declining their population. At present, the practice of clearing out ecosystems for agriculture conversion and industrial expansion continues to displace organisms of their natural habitat. Biodiversity is vital to boost productivity in ecosystems where species depend on to live. Natural ecosystems suck up 60% of our carbon emissions, and nature-based solutions, like planting trees, nurturing soils, and restoring ecosystems, can provide over a third of the climate solutions needed until 2030 with huge benefits for biodiversity. Seized ivory in Malaysia (Shutterstock) The illegal wildlife trade is the fourth largest criminal industry in the world, after drugs, arms and human trafficking.

The World Environment media platform with its printed Magazine, Web TV, news letter and press releases act as a reference and as a practical guide for Green workers, conscious professionals, leaders, and citizens of the world. Biodiversity represents the knowledge learned by evolving species over millions of years. SI Opener: Loss of biodiversity is a bigger threat than climate change. Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Biodiversity and habitat loss. Consider the following examples. Some of these changes are already visible. This phenomenon does not only affect wildlife but also human health as well. 80%-90% of threatened species are under threat as a result of habitat loss or fragmentation . These are the 5 biggest threats to the world's wildlife. Biodiversity is vital to keep all life on Earth healthy, balanced and thriving. One good example of this are the epidemics and infectious diseases of wildlife such as Ebola virus disease, infectious bursal disease, and flu. Human Activities and Loss of Habitat, 2. Aside from the five aforementioned threats, there are still a lot of drivers that may either directly or indirectly contribute to the loss of biodiversity. Alarming decline “The Living Planet Index is one of the most comprehensive measures of global biodiversity. Its mere presence poses huge challenges to the conservation measures intended to natural habitats and species living there. The third focal area of the 2010 framework concerns the five major threats to biodiversity: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

This introduction can cause major threats to the native species as they often become subjected to great competition for resources, disease, and predation. Take the Great Barrier Reef for example. Before looking at biodiversity’s biggest threats, first thing’s first—how exactly has biodiversity changed over the years? This makes the Pacific islands quite unique in their conservation situation compared with other tropical regions. Because of this, species population is put into great risk of reduction. The greatest threat to biodiversity is the size and rate of growth of human population. Because many natural species survive only in a particular environment, they tend to be displaced, or worse, perish. The human population requires resources to survive and grow, and those resources are being removed unsustainably from the environment. The overuse of natural parks and watershed as tourist destinations and recreational spots also threatens biodiversity due to the fact that humans cause too much noise and perturbations that disrupt the animals’ normal activities. 24-09-2020 | SI Opener. Man has begun to overuse or misuse most of these natural ecosystems. Most exotic species are brought to a certain place to replace or add something to the vegetation. Another form of pollution that can damage and kill living organisms is acid rain. Overharvesting, overfishing, and overhunting are some examples of overexploitation. Habitats which protect wildlife are being converted to human settlements harbours, dams, reservoirs, croplands, grazing grounds and plantation. 6%. Biodiversity is vital to boost productivity in ecosystems where species depend on to live. Desertification, 4. The loss of genes and individuals threatens the long-term survival of a species, as mates become scarce and risks from inbreeding rise when closely related survivors mate. This rain is usually a result of pollution coming from the excessive burning of fossil fuels. The loss of pollinators threatens the production of agricultural commodities that depend on them. Biodiversity loss could become a greater threat to humanity than climate change and we are “running out of time” to turn things around, a Queensland academic warns. Habitat loss, pesticide use and artificial light are three of the most serious threats to fireflies, with certain species more at risk than others. Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics. Some of the main threats to biodiversity are: 1. WWF uses the Living Planet Index (LPI) to measure biodiversity worldwide. Marine Environment, 5. Habitat loss is the biggest hazard to plant biodiversity. Climate change, the biggest threat to biodiversity, is a huge source of biodiversity loss through habitat loss, lack of livable and thrivable environments. What is habitat loss or habitat fragmentation? In the medium-term, the global economy will be threatened by the knock-on effects of the coronavirus crisis, while geopolitical stability will … But bear in mind that biodiversity is more than just species. This loss of biodiversity reportedly poses as serious, and urgent, a threat to humans as climate change but it has been less discussed. Taking a step back then, we can see that the biggest threat to biodiversity is the exponential population growth of homo sapiens and consequent urbanization. Land-use changes, pollution, overexploitation of resources, and climate change were listed as the biggest drivers of this biodiversity loss. Habitat loss is the single greatest threat to biodiversity on Earth today and in fact it is the second largest threat to our existence on this planet next to Climate Change. This makes sense, considering that approximately one acre of the Earth’s rainforests is disappearing every two seconds. NEWS Plant life in peril - IUCN and Kew Gardens study In meeting our demands for food, shelter, clothing and consumer goods, we are destroying the of habitats of other species without check. Study sets. 15 biggest emerging trends and threats to biodiversity in 2019.

The core threat to biodiversity on the planet, and therefore a threat to human welfare, is the combination of human population growth and resource exploitation. The most significant of which are climate change, habitat loss, species loss, and infrastructure (development). According to an analysis of data from the International Union for the Conservation of Nature (IUCN), habitat loss is the number-one threat to biodiversity worldwide. So as a population or ecosystem continues to suffer from low species diversity, the probability of getting wiped out completely when a natural disaster or other forces increases. : Habitat Loss,Invasive Species, Pollution, HumanPopulation, and Overharvesting. Despite the profound threat of biodiversity loss, it is climate change that has long been considered the most pressing environmental concern. Aside from this, human-induced activities which include economic, technological and scientific, cultural, and demographic factors also have an impact on biodiversity. It helps make the global economy more resilient, it functions as an integral part of our culture and identity, and research has shown it’s even linked to our physical health. Natural ecological disturbances , such as wildfire , floods , and volcanic eruptions , change ecosystems drastically by eliminating local populations of some species and transforming whole biological communities . Some places have very low possibilities for the invasion of species. The greatest threat that invasive species can bring is their capability to change an entire habitat.
