Why is biodiversity so important? - Kim Preshoff

Exhaustible resources are those which are limited and will be exhausted with continuous usage, for example, coal, natural gas etc. As the population of the world is increasing at an alarming rate, the consumption of natural resources is also increasing. Hence, these resources should be conserved to maintain ecological balance and save them for future generations. The proper management of a resource to prevent its destruction or exploitation is called conservation.

Nature provides us with all the essentials for our daily needs. Due to overpopulation and human negligence we started to over-exploit our resources. If this continues, there will no resources left for our future generation. The need to conserve the resources are. Terracing: Terrace farming helps to control the fast flow of water which takes away soil with its flow. It is usually practised in hilly areas. Soil fertility: Maintenance of soil fertility is obtained by adding manure or fertilizers or even by crop rotation. Treatment of Industrial Wastes: The chemical wastes must be treated before releasing them into the water bodies. Dams and Reservoirs: Dams help to store water and supply them when needed. They also help in producing energy. Growing Flora: It helps to prevent the flow of water and makes it sink into the soil increasing groundwater levels.

These include coal, biomass natural gas etc. These are exploited every day in one form or the other. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. Natural environment is often used as a synonym for habitat , for instance, when we say that the natural environment of giraffes is the savanna. Earth science generally recognizes four spheres, the lithosphere , the hydrosphere , the atmosphere , and the biosphere [3] as correspondent to rocks , water , air , and life respectively. Some scientists include as part of the spheres of the Earth, the cryosphere corresponding to ice as a distinct portion of the hydrosphere, as well as the pedosphere corresponding to soil as an active and intermixed sphere.

Earth science also known as geoscience, the geographical sciences or the Earth Sciences , is an all-embracing term for the sciences related to the planet Earth. These major disciplines use physics , chemistry , biology , chronology and mathematics to build a qualitative and quantitative understanding of the principal areas or spheres of Earth. The Earth's crust , or lithosphere , is the outermost solid surface of the planet and is chemically and mechanically different from underlying mantle.

It has been generated greatly by igneous processes in which magma cools and solidifies to form solid rock. Beneath the lithosphere lies the mantle which is heated by the decay of radioactive elements. The mantle though solid is in a state of rheic convection. This convection process causes the lithospheric plates to move, albeit slowly. The resulting process is known as plate tectonics. Volcanoes result primarily from the melting of subducted crust material or of rising mantle at mid-ocean ridges and mantle plumes.

Most water is found in various kinds of natural body of water. An ocean is a major body of saline water , and a component of the hydrosphere. More than half of this area is over 3, meters 9, ft deep. Average oceanic salinity is around 35 parts per thousand ppt 3. Though generally recognized as several separate oceans, these waters comprise one global, interconnected body of salt water often referred to as the World Ocean or global ocean. The major oceanic divisions are defined in part by the continents , various archipelagos , and other criteria: these divisions are in descending order of size the Pacific Ocean , the Atlantic Ocean , the Indian Ocean , the Southern Ocean and the Arctic Ocean.

A river is a natural watercourse , [7] usually freshwater , flowing toward an ocean , a lake , a sea or another river. A few rivers simply flow into the ground and dry up completely without reaching another body of water. The water in a river is usually in a channel , made up of a stream bed between banks. In larger rivers there is often also a wider floodplain shaped by waters over-topping the channel. Flood plains may be very wide in relation to the size of the river channel. Rivers are a part of the hydrological cycle. Water within a river is generally collected from precipitation through surface runoff , groundwater recharge , springs , and the release of water stored in glaciers and snowpacks. Small rivers may also be called by several other names, including stream , creek and brook.

Their current is confined within a bed and stream banks. Streams play an important corridor role in connecting fragmented habitats and thus in conserving biodiversity. The study of streams and waterways in general is known as surface hydrology. A lake from Latin lacus is a terrain feature , a body of water that is localized to the bottom of basin.

A body of water is considered a lake when it is inland, is not part of an ocean , and is larger and deeper than a pond. Natural lakes on Earth are generally found in mountainous areas, rift zones , and areas with ongoing or recent glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world, there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them. A pond is a body of standing water , either natural or man-made, that is usually smaller than a lake.

A wide variety of man-made bodies of water are classified as ponds, including water gardens designed for aesthetic ornamentation, fish ponds designed for commercial fish breeding, and solar ponds designed to store thermal energy. Ponds and lakes are distinguished from streams by their current speed. While currents in streams are easily observed, ponds and lakes possess thermally driven micro-currents and moderate wind driven currents. These features distinguish a pond from many other aquatic terrain features, such as stream pools and tide pools.

Humans impact the water in different ways such as modifying rivers through dams and stream channelization , urbanization , and deforestation. These impact lake levels, groundwater conditions, water pollution, thermal pollution, and marine pollution. Humans modify rivers by using direct channel manipulation. Dams can usefully create reservoirs and hydroelectric power.

However, reservoirs and dams may negatively impact the environment and wildlife. Dams stop fish migration and the movement of organisms downstream. Urbanization affects the environment because of deforestation and changing lake levels, groundwater conditions, etc. Deforestation and urbanization go hand in hand. Deforestation may cause flooding, declining stream flow, and changes in riverside vegetation. The changing vegetation occurs because when trees cannot get adequate water they start to deteriorate, leading to a decreased food supply for the wildlife in an area.

The atmosphere of the Earth serves as a key factor in sustaining the planetary ecosystem. The thin layer of gases that envelops the Earth is held in place by the planet's gravity. The remaining gases are often referred to as trace gases. Filtered air includes trace amounts of many other chemical compounds. Air also contains a variable amount of water vapor and suspensions of water droplets and ice crystals seen as clouds.

Many natural substances may be present in tiny amounts in an unfiltered air sample, including dust , pollen and spores , sea spray , volcanic ash , and meteoroids. Various industrial pollutants also may be present, such as chlorine elementary or in compounds , fluorine compounds, elemental mercury , and sulphur compounds such as sulphur dioxide SO 2. The ozone layer of the Earth's atmosphere plays an important role in reducing the amount of ultraviolet UV radiation that reaches the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes. Earth's atmosphere can be divided into five main layers.

These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are:. Within the five principal layers determined by temperature there are several layers determined by other properties. The dangers of global warming are being increasingly studied by a wide global consortium of scientists. Of particular concern is how climate change and global warming caused by anthropogenic , or human-made releases of greenhouse gases , most notably carbon dioxide , can act interactively, and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect , which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth.

The most recent report from the Intergovernmental Panel on Climate Change the group of the leading climate scientists in the world concluded that the earth will warm anywhere from 2. Some examples of recent collaboration to address climate change and global warming include:. A significantly profound challenge is to identify the natural environmental dynamics in contrast to environmental changes not within natural variances. A common solution is to adapt a static view neglecting natural variances to exist. Methodologically, this view could be defended when looking at processes which change slowly and short time series, while the problem arrives when fast processes turns essential in the object of the study.

Climate looks at the statistics of temperature , humidity , atmospheric pressure , wind , rainfall , atmospheric particle count and other meteorological elements in a given region over long periods of time. Climates can be classified according to the average and typical ranges of different variables, most commonly temperature and precipitation. The Thornthwaite system, [21] in use since , uses evapotranspiration as well as temperature and precipitation information to study animal species diversity and the potential impacts of climate changes.

Weather is a set of all the phenomena occurring in a given atmospheric area at a given time. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. Weather occurs due to density temperature and moisture differences between one place and another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics.

The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes , such as extratropical cyclones , are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. Over thousands of years, changes in the Earth's orbit have affected the amount and distribution of solar energy received by the Earth and influence long-term climate. Surface temperature differences in turn cause pressure differences.

Higher altitudes are cooler than lower altitudes due to differences in compressional heating. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The atmosphere is a chaotic system , and small changes to one part of the system can grow to have large effects on the system as a whole. Human attempts to control the weather have occurred throughout human history, and there is evidence that civilized human activity such as agriculture and industry has inadvertently modified weather patterns.

Evidence suggests that life on Earth has existed for about 3. There are many different hypotheses regarding the path that might have been taken from simple organic molecules via pre-cellular life to protocells and metabolism. Although there is no universal agreement on the definition of life, scientists generally accept that the biological manifestation of life is characterized by organization , metabolism , growth , adaptation , response to stimuli and reproduction. In biology , the science of living organisms, "life" is the condition which distinguishes active organisms from inorganic matter , including the capacity for growth, functional activity and the continual change preceding death.

A diverse variety of living organisms life forms can be found in the biosphere on Earth, and properties common to these organisms—plants, animals , fungi , protists , archaea , and bacteria —are a carbon - and water -based cellular form with complex organization and heritable genetic information. Living organisms undergo metabolism , maintain homeostasis , possess a capacity to grow , respond to stimuli , reproduce and, through natural selection , adapt to their environment in successive generations.

More complex living organisms can communicate through various means. An ecosystem also called as environment is a natural unit consisting of all plants, animals and micro-organisms biotic factors in an area functioning together with all of the non-living physical abiotic factors of the environment. Central to the ecosystem concept is the idea that living organisms are continually engaged in a highly interrelated set of relationships with every other element constituting the environment in which they exist. Eugene Odum , one of the founders of the science of ecology , stated: "Any unit that includes all of the organisms i. A greater number or variety of species or biological diversity of an ecosystem may contribute to greater resilience of an ecosystem, because there are more species present at a location to respond to change and thus "absorb" or reduce its effects.

This reduces the effect before the ecosystem's structure is fundamentally changed to a different state. This is not universally the case and there is no proven relationship between the species diversity of an ecosystem and its ability to provide goods and services on a sustainable level. The term ecosystem can also pertain to human-made environments, such as human ecosystems and human-influenced ecosystems, and can describe any situation where there is relationship between living organisms and their environment. Fewer areas on the surface of the earth today exist free from human contact, although some genuine wilderness areas continue to exist without any forms of human intervention.

Biomes are terminologically similar to the concept of ecosystems, and are climatically and geographically defined areas of ecologically similar climatic conditions on the Earth, such as communities of plants , animals, and soil organisms , often referred to as ecosystems. Biomes are defined on the basis of factors such as plant structures such as trees, shrubs, and grasses , leaf types such as broadleaf and needleleaf , plant spacing forest, woodland, savanna , and climate.

Unlike biogeographic realms , biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation. Global biogeochemical cycles are critical to life, most notably those of water , oxygen , carbon , nitrogen and phosphorus. Wilderness is generally defined as a natural environment on Earth that has not been significantly modified by human activity. The WILD Foundation goes into more detail, defining wilderness as: "The most intact, undisturbed wild natural areas left on our planet — those last truly wild places that humans do not control and have not developed with roads, pipelines or other industrial infrastructure.

Wilderness is deeply valued for cultural, spiritual, moral , and aesthetic reasons. Some nature writers believe wilderness areas are vital for the human spirit and creativity. The word, "wilderness", derives from the notion of wildness ; in other words that which is not controllable by humans. The mere presence or activity of people does not disqualify an area from being "wilderness. 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.
