Wildlife-Conservation and Importance(India)

When humans develop land for houses and building, they cut down trees and changed animal and plant habitats. Some animals, like the raccoon and the skunk, can adapt, but other animals can’t adapt and their population is

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

Habitat fragmentation, loss and degradation - fragmentation, loss, and degradation of natural habitats, and has also contributed to habitat and species isolation.

In today’s world, hardly any species of wildlife become extinct from natural causes. Europeans hunt animals to such an extent that we classify it as overhunting. We destroy their habitat, and introduce other animals that are a threat to endangered animals or are competition for resources and food. Habitat destruction is the greatest threat to both animals and plants.

Out of all the problems our environment faces like pollution and global warming, one of the most threatening problems is invasive species. An invasive species is an organism that is not native to an ecosystem and causes harm. They can harm the environment, economy, and even human health. When an invasive species starts to affect the economy, it becomes a bigger problem because it starts to get expensive to maintain and control.

Although the natural ecosystem is a dynamic system that is always changing in response to environmental changes ("Invasive Alien Species in Canada." Government of Canada, Environment Canada. Government of Canada, 19 July 2013. Web. 8 July 2015. . ) . Invasive species affect the ecosystem in a negative way, both in the short term and longer term altering not only the habitat but impacting native species abundance and richness. Invasive species are successful at adapting to new environments so readily because they are generalist. Meaning that they have traits and physiological characteristics that allow them to thrive in variety of conditions, they don’t have any predators in the new environment and they are able to reproduce quickly ("Characteristics of Invasive Species." Web. 8 July 2015. .).

Initially, habitat loss possibly poses the greatest threat to species as their homes (biomes) are harvested for industrial purposes and human

Earth is home to many diverse and mysterious species. These species thrive within their own ecosystem by adapting to their living habitats and food source. Though when human actions introduce new species to a foreign area where that species never lived before, this is called an exotic species (Phelan, 2013, p.640). Some of these exotic species normally do not cause a threat to the ecosystem to which it is introduced, however some do and these are called invasive species. Invasive species tend to have no predators therefore they can multiply at vastly large numbers and outcompete the native species’ food source and living space. Furthermore these native species have no prior mechanisms to defend themselves from the new invasive species therefore they can fall prey to these new invaders (Phelan, 2013, p.640).

Altering the biodiversity could cause the loss of an environment such as the Malayan field rat incident in the Chiew Larn islands. Laurance, William wrote the article, Islands of Extinction, which speaks of the Chiew Larn and how the reservoir was flooded. Larger animals perished due to the fact of how small Chiew Larn islands were during the flood. Chiew Larn island measures from 1 hectare, 2.5 acres, to 60 hectares, 148 acres. Some large animals such as tigers, deer, and elephants might have disappeared into the forest surrounds the reservoir. Because of this flood, it was easier for the Malayan field rat to come and invade the Chiew Larn islands. One of William colleague, Tony Lynam, traveled and did an experiment on the Chiew Larn islands after the flood. Tony’s experiment was to use baited live traps to capture small mammals left on the island and ear tags them. The result that Lynam had discovered was astounding because the native mammal species had vanished within 10 hectares of the area (Laurance, 2014). The tragic change of the environment had lost the once healthy and plentiful biodiversity in the area. This is the start of an invader known as the Malayan field rat. A Malayan field rat, an adaptable species, can be compared to the well and common known black rat. The Malayan field rat lives near human settlements and agriculture. Luke Gibson, a Ph.D. student at the

The examples of wildlife losing their territory are numerous, and discovered all over the place. In Vermont, the Savannah Sparrow has lost its nesting grounds because of agricultural haying practices (Faccio 2008). In Florida, beachfront property is drawing nearer and closer to the shoreline. Raccoons are increasing in number as sea turtles, tortoises, seabirds, and crab populations all decrease (Rupert 2008). Urban sprawl has also resulted in forest degradation with grasslands, oak savannas, oak and Pine Barrens lands declining rapidly. These woods are being gathered for business utilization, furthermore being cleared for further human advancement and infrastructural needs. In Wisconsin, just 1% of old world oak is left (CWAC

According to Van Driesche, nonnative species are more likely to establish if they invade habitats with lowered biotic resistance, encounter prey with poorly developed mechanisms of self-defense, or invade habitats unaccompanied by their specialized natural enemies or when their invasion is facilitated by earlier invaders (2000).  Damage to these communities, then, can be seen both in cumulative effects and in a cycle of self-reinforcement.  Although pristine environments are still at risk from invasion, this positive feedback loop makes habitats already with a disturbance by exotics even more vulnerable to other invasions.

Deforestation for agricultural purposes and the expansion of human habitats is happening around the world. This

Wildlife includes all non-domesticated plants, animals, and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems, Deserts, rain forests, plains, and other areas including the most developed urban sites all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that wildlife around the world is impacted by human activities.
