Impacts Of Anthropogenic Activities And Land Use Changes On Biodiversity Conservation

Biodiversity describes the variety of different types of life found on Earth. It is extent of the variety of organisms present in different ecosystems. This can denote to genetic variation, ecosystem, variation, or species disparity (number of species) inside an area, biome, or planet.

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About

Biodiversity, or biological diversity, is a term first coined in 1985 by Walter G. Rosen concerning the number of species in a particular habitat and revolved around the idea that diversity cannot solely be understood through numbers (Maclaurin and Sterelny, 2012). However, before 1985 biodiversity was related to concepts of “genetic diversity and ecological diversity”. This allowed to further define ecological diversity with species richness as “the number of species in a community of organism”. Biodiversity is more than just the amount of species in an area but rather better measured by taxic measures, molecular measures, and phylogenetic measures (Harper and Hawksworth, 1994).

Biodiversity means the variety of life forms/organisms in an ecosystem, biome or entire planet. Globally, biodiversity is not evenly distributed. It generally increases from the poles towards the equator as around 50% of the world’s plants and animals live in tropical rainforests. This is because of the proximity to the equator causing a warmer, more moist, stable climate which means plants grow better and can support more species higher up in the food chain. Standard of living is the level of wealth, goods and

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

So we will talk about biodiversity first. Biodiversity is a group of different living organisms from around the world in one community. And biodiversity helps the biosphere because they can produce better and help other plants and humans in need. Some plants and trees have different characteristics regarding to their species.

Biodiversity is the variety of spices within plants and animals in the environment, it is an indicator of ecosystem health.

On May 8th the grades Biology students went on an excursion to the rocky shore Pt. Cartwright. Rocky shores are where the land meets the sea. On the Rocky shore there are different zones that are based on tidal level, this means the rocky shore is a quickly changing environment and due to this unique condition it gives a large biodiversity. Biodiversity is the term given to the variety of life on Earth. It is the variety within and between all species of plants, animals and microorganisms and the ecosystems within which they live and interact (Wwf.org.au).

Biodiversity accounts for the difference in life throughout our planet. The different animal kingdoms throughout ecosystems is the most notable example of biodiversity. Biodiversity is the entire spectrum of species that live in the biosphere. A small pond such as the ones that will be sampled are ecosystems to frogs, lilies, and insects and an

The Millennium Ecosystem Assessment’s Summary for Decision-Makers brought to light the fact that the rate of species extinction, over time, has increased at an alarming rate. This is distressing because species extinction means loss of biodiversity: a measure of a healthy environment. There are five main drivers, that are interconnected, that influence biodiversity loss and species extinction. While all five are interconnected they are strongly related to one in particular. That driver is human population size. The other four drivers are habitat destruction, overexploitation of resources, pollution, and the introduction of alien species. Biodiversity loss and species extinction, and the healthiness of the environment, are all influenced by

Biodiversity is the variety of plant and animal life in the world and as such is an important aspect of all human life. Nature provides food, and ways of preventing diseases. Overall, it makes Earth a livable place for all life. It’s been estimated that there are around thirty million species on earth but only around 1.7 million are identified. The issue with biodiversity is that it is rapidly declining in many parts of the world and once the biodiversity in an area is wiped out, it is basically impossible to revive. There are a couple of reasons as to why there is a steady decline in biodiversity. Some of the ways include habitat loss, spread of diseases or invasive species, and climate change. One way the rate at which biodiversity decreases

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and

Humans have existed since 200,000 years but the Earth has existed around 4.5 billion years. Nature has provided us with everything we have today - food, medicines, materials, chemicals, metals, minerals etc. It can only keep providing us when we maintain the right environment for it to exist. This environment depends on the biodiversity of Earth. The number of species of plants, animals and microorganisms and the various genes in these species, different ecosystems such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Hence Biodiversity impacts everything. We will discuss how Biodiversity plays a crucial role on social, environmental, and economic factors. We will also discuss what

In addition, the interactions taking place between world economics and biodiversity also has to be taken into consideration. The arguments for the conservation of biodiversity with regards to economics are divided quite broadly into ‘direct use value’ and ‘indirect use value’. direct use value is involved with microbial products such as animals and plants whereas indirect use is involved with the ecosystem services that are provided by a group of species and habitats, these include the likes of flood

Although sustainable development has been at the forefront of international agenda for many years, we continue to focus on the growth of the economy without worrying about the impact on the environment. Currently, our ecological footprint (the area in hectares that we require to provide us with the ecological goods and services we use) is far exceeding our biocapacity (the actual land available to provide these services); with the human population requiring over 1.5 earths to sustain the amount of resources we use each year (WWF, 2014). As the growth of the human population shows no sign of slowing down, with predictions there will be a further 2.4 billion people on the planet by 2050 (WWF, 2014), the pressures we exert on the planet will only increase. This overuse of resources is not only making it difficult to support our needs, but is also leaving little space and resources left for all the other species around the globe to thrive, and more importantly, survive. This has led to a decline in biodiversity at a much faster than would be seen under natural circumstances.
