Biodiversity is affected by five main pressures: habitat loss and degradation, climate change, excessive nutrient load and pollution, over-exploitation, and invasive alien species. As mentioned before, humans are not the only force that influences the environment. Natural events such as volcanic eruptions can potentially disrupt an ecosystem’s balance as well. However, at least three out of five of the principle pressures are caused by humans, although it is arguable that we do play a crucial role in speeding climate change and transporting invasive species. Ecosystem degradation and biodiversity loss is almost like the result of the other issues.
The impacts of this issue are important in many ways. Up to forty percent of the world’s economy depends on natural resources, and perpetually using these resources inevitably means that they will run out. The economy would suffer greatly. It wouldn’t be accustomed to using other sources of energy after depending on non-renewable resources for so long. Without biodiversity, large amounts of money have to be spent to provide services that were otherwise given to us free by nature. For example, oceans recycle sewage into nutrients, remove toxins from the water,...

- The Loss of Biodiversity on the Ecosystems A person’s health and welfare is subject to ecosystem benefits supplied by natural surroundings, such as the purification air and water, fisheries, woodlands, and nutrient recycling. These are principally commodities with no retails as well as no prices, hence their depletion frequently is not sensed by new economic money methods and may thus endure unrestricted. Resulting in a variety of pressures from population growth to climate change that causes biodiversity to deteriorate, and ecosystems are ceaselessly being defiled (EPA, 2011)....

- What is deforestation, degradation and climate change Deforestation: It implies the long term permanent loss of forest cover and implies transformation into another land use. Such a loss can only be caused and maintained by a continued human-induced or natural perturbation (FAO, 2001). Forest degradation: The long term reduction of the overall potential supply of benefits from the forest, which includes carbon, wood, biodiversity and other goods and services (FAO, 2003). Climate change: It refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer)....

- Introduction Biodiversity refers to wide diversity found in the living components of the earth which refers to the numerous varieties of flora and fauna including those of microorganisms too. The interaction of biotic and abiotic components of the ecosystem is very important aspect of life on earth. Biodiversity helps us to understand the variations among species and also how life originated on earth. Its study helps us to understand the inter-relationship between various forms of life and their adaptation to different conditions.... [tags: Ecosystems]

- We don’t often stop to consider the impact that simply living our human lives has on the other species that once called our neighbourhoods their home. The Fraser Valley, “one of the most important and complex ecosystems in the country” (Thom, p. 171), has been dramatically altered to make a more convenient landscape for housing and farming. In this process, critical habitat has been destroyed and many species that were once abundant have disappeared from our area (Cuthbert p. 24). Urbanization is ongoing and is thought to be the most significant threat to the incredible biodiversity found throughout British Columbia, and particularly the population-dense Lower Mainland (Harding, p....

- ... Community forestry has contributed to improving and diversifying livelihoods by mobilizing locally available natural forest. As per the Forest Act (1993), community forest user groups (CFUGs) retain 100% of revenues generated and 25% are used in forest development activities (Ojha, Persha & Chhatre, 2009). Under CF, the focus is to meet the local’s demand regarding forest products and protect forest, so CFUG are the manager of the forest. The CF’s priority is protection and production of forest related needs for its user (Acharya, 2004; Shrestha, Shrestha & Shrestha, 2010), this will complement the goal of REDD+....

They are hunted for their horn to be used for medicines. Gee's Golden Langur is a species that are threatened by habitat loss. They are losing their habitat because of deforestation. Data about a species’ decline rate, population size, area of geographic distribution, and amount of fragmentation in population are used to identify what classification level a species is in....

- Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood. In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages. In the Earth’s history, changes have often occurred in the ecosystems. For example, glaciers and the retreat of glaciers cause wide-spread changes. However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses....

- Many people have different ideas about what an endangered species is, but the definition of endangered species is a type of animals and plant which is in danger for extinction by different reason . In this modern time, we see a lot of animals disappearing because of humans. This action is made with no or indifferent care about life and existence of biodiversity species and there contribution to the ecosystem of the world. In addition the uncontrolled humans developing is causing serious damage to the habitat in which species can't sustain their life's generating a very prolonged list of endangers species as a result....

- "If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us." -- David Suzuki Imagine this: bulldozers growl and grind through a local field, while the whine of chainsaws echoes from a nearby grove of trees. The trees crash to the ground, only to be cut up for firewood or sent to a sawmill, and the remaining ground is cleared of stumps and plowed. The tall grasses and brush in the field are demolished, leaving behind churned-up soil.... [tags: Loss of Biodiversity]

- Biodiversity degradation are becoming one the worst global environmental catastrophes. Given the status of the world’s biological resources on which so much of human life depends, biodiversity loss is among the world’s most pressing crisis and there is growing global concern on slowing down population declines and extinctions (Wilson 1988; WHO 2005; McKinney et al. 2009; Soberon and Peterson 2009). The current estimation on the extinction rate ranges between 1,000 and 10,000 times higher than the natural rate (Kumar and Khanna 2008).... [tags: Environmental Catastrophe, Biodiversity ]
