The astonishing diversity of life is a product of millions of years of evolution. Nonetheless, this diversity is in danger, and many species are about to go extinct. Mitigating this crisis will require explaining the factors that put these species at risk and the measures to save them.
Endangered species are in immediate danger of becoming extinct within a specified period. They may include majestic animals such as elephants and tigers or rare animals such as the axolotl and the saola. According to the International Union for Conservation of Nature (IUCN), such species are rated depending on their population decline, habitat range, and other environmental pressure; they may be ranked vulnerable, endangered, or critically endangered.
Endangered species are at threat not only for their reasons but also for their own. Every species within the ecosystem is critical to fulfilling certain functions that may involve pollination, the dispersal of seeds, or nitrogen recycling. Hence, the extinction of one species from the food web may result in numerous interrelated species being affected as food webs are disrupted. The fact that certain species are endangered and are in danger of disappearing does not only mean that there will be a loss of beauty in nature.
For instance, the gradual extinction of bee and butterfly pollinators will render most agricultural activities useless and threaten the world's food supply. In like manner, when large animals at the top of the food chain, like wolves and sharks, are wiped out, their prey species tend to overpopulate and damage the habitats. There are also significant consequences that demonstrate why conservation is essential.
Extinction is an inevitable occurrence of nature and has occurred in Earth's evolution. However, the current extinction rate is disheartening and anthropogenic. Scientists estimate that Earth is losing species at a one hundred to a thousand times higher than the natural background rate. Owing to this increased loss, researchers have proved that we are currently in the Sixth Mass Extinction Era.
The foremost reason for such a crisis is human interference with nature through activities such as deforestation, environmental pollution, wastage of marine resources, and global warming. The loss of natural habitat due to farming or towns is very destructive since it wipes out the area where organisms exist and reproduce. Climate change exacerbates the existing threats by modifying systems, moving locations, and creating a mode of travel with weather conditions that a particular species may not be swift enough to cope with.
Another factor known to cause extinction is invasions of appositely named invasive species. Non-indigenous species tend to be introduced to new habitats intentionally or accidentally. When this occurs, they are usually more successful in acquiring resources and prevalence than the indigenous species, sometimes to the point of preying upon them. A case is that of cane toads in Australia that have taken a toll on some native species by secreting toxins to the predators and competing for space with other frogs.
For researchers to be able to put into practice sustainable strategies to combat the extinction problem, the need to know the extinction mechanisms is very relevant. This includes both the study of such features as the level of genetic diversity, population dynamics, and factors in the ecosystem. So that those species and habitats which are under threat can be dealt with as a priority.
When habitats are destroyed, the plants and animals that depend on them often cannot survive. This decreases biodiversity, weakening ecosystems and making them less resilient to environmental changes like disease outbreaks or natural disasters.
In the context of ecological disturbance, habitat fragmentation is splitting vast and continuous habitats into smaller patches that become isolated from each other. Such isolation hinders species movement, such as mate finding, emigration, and even resource access. Urban development and roads hinder wildlife movement and often prevent animate beings such as bears, tigers, and deer from accessing their home ranges.
Certain species, often referred to as extreme specialists, can live only under very specific conditions or use a narrow range of resources. Such species are more likely to go extinct when their environments are altered. This is especially true for the giant panda, which is highly endangered because its existence depends on bamboo forests.
A habitat is not just a housing unit for a …population. It is a stage where certain ecological activities are taking place. For example, a forest is a carbon sink, wetlands are water filtration systems, and mangroves prevent sea erosion. When such habitats are destroyed, all those activities are stopped, creating ecological and economic crises.
Contraction of territories leads to self-seeking behavior in many animal species, driving them closer to already-established settlements in search of shelter and food. Therefore, this gives rise to human-wildlife interactions whereby elephants destroy farms in search of crops or wild carnivores because of livestock predation. In addition, these interactions create opportunities for the revenge killing of such individuals, putting them at more risk.
Perhaps one of the best ways to protect biodiversity is through the establishment of national and provincial parks, wildlife and marine reserves. Protected areas confine species that are able to reproduce without the fear of hunting, logging, or industrialization. National Park Serengeti of the Republic of Tanzania and the Great Barrier Reef Marine Park of Australia are examples of such initiatives.
Poaching and the illegal trade of wildlife are another major difficulties that may challenge the survival of species like rhinos, elephants, and pangolins. This is because the poaching of endangered species and the threat to their habitat are contained by enhancing international treaties like the Convention on International Trade in Endangered Species (CITES).
Destructive resource practices like agriculture expansion, overfishing, and logging destroy and use up habitats. Therefore, negative impacts would be reduced while livelihoods would be supported through the promotion of agroforestry, imposing limits to fishing with the establishment of quotas, and using eco-friendly timber products.
Many projects allow for damaged systems to be restored, such as reforestation, wetland restoration, and wildlife corridors. These projects provide areas for wildlife to thrive and also help the surrounding community by cleaning the air and water and enriching the soil.
Most importantly, it is necessary to inform people why they should care about biodiversity and what threatens it. Education can take the form of films, lessons, or even social networking, and these mediums can lead people to help out by giving money to the cause, living less wasteful lifestyles, or lobbying for better environmental protection laws.
