Biodiversity And Deforestation

Biodiversity And Deforestation

Despite the importance of forests, they are being removed at frightening rates. greenhouse gas produced by animals during respiration and used by plants during photosynthesis. Trees are cut down for timber, waiting to be transported and sold.

issued edicts restricting the slaughter of animals and certain kinds of birds, as well as opened veterinary clinics. Efforts are made to preserve the natural characteristics of Hopetoun Falls, Australia, without affecting visitors’ access. In Great Britain, where both groups are well known, there are six times as many named species of fungi as of flowering plants.

The consensus has grown to 100% among research scientists on anthropogenic global warming as of 2019. No scientific body of national or international standing disagrees with this view. Consensus has further developed that some form of action should be taken to protect people against the impacts of climate change, and national science academies have called on world leaders to cut global emissions. Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming and the effects it has on our planet.

The natural factors affecting forests are arid climate, heavy dependence on irrigation water, long gestation periods of forestry, and fragile watershed & rangeland. Commercial exploitation and harvesting of forests by the contractors with the connivance of the concerned officials is not only exploiting small forest owners with weak financial positions but also causing deforestation on a massive scale. The forest department has failed to bring them to book and rectify the situation. The ban imposed by the government on cutting trees has not prevented the timber mafia from their activities because of political interference, theft, corruption and lack of serious commitment on the part of the government to bring the culprits to book. The timber traders are using all possible means to smuggle wood for short-lived gains. In 1993, the consumption of wood was 29.5 million cubic meters whereas in the year 2018 it is projected to go up by 52.6 million cubic meters.

In the 19th century, introduction of steamboats in the United States was the cause of deforestation of banks of major rivers, such as the Mississippi River, with increased and more severe flooding one of the environmental results. The steamboat crews cut wood every day from the riverbanks to fuel the steam engines. Between St. Louis and the confluence with the Ohio River to the south, the Mississippi became more wide and shallow, and changed its channel laterally. Attempts to improve navigation by the use of snag pullers often resulted in crews’ clearing large trees 100 to 200 feet back from the banks. Several French colonial towns of the Illinois Country, such as Kaskaskia, Cahokia and St. Philippe, Illinois, were flooded and abandoned in the late 19th century, with a loss to the cultural record of their archeology.


Habitat fragmentation also poses challenges, because the global network of protected areas only covers 11.5% of the Earth’s surface. A significant consequence of fragmentation and lack of linked protected areas is the reduction of animal migration on a global scale. Considering that billions of tonnes of biomass are responsible for nutrient cycling across the earth, the reduction of migration is a serious matter for conservation biology. Conservation biologists have started to collaborate with leading global economists to determine how to measure the wealth and services of nature and to make these values apparent in global market transactions. This system of accounting is called natural capital and would, for example, register the value of an ecosystem before it is cleared to make way for development. The WWF publishes its Living Planet Report and provides a global index of biodiversity by monitoring approximately 5,000 populations in 1,686 species of vertebrate and report on the trends in much the same way that the stock market is tracked.

This shows the process of the air pollution being released into the atmosphere and the areas that will be affected. Soils of coniferous forests are naturally very acidic due to the shedding of needles, and the results of this phenomenon should not be confused with acid rain. This rule provides states with a solution to the problem of power plant pollution that drifts from one state to another.

Another way to encourage the market adoption of alternative fuel vehicles is simply to finance them through consumer incentives. Often manifesting in the form of tax breaks, government incentives can effectively bring the price of alternative fuel vehicles down to price ranges where more people can afford them. There are big hurdles facing both hydrogen fuel cell and battery-powered vehicles, but they’re different for each. In simple terms, the biggest problem with fuel cell cars is how rare hydrogen stations are. For electric cars, it’s how long it takes to charge the battery and the comparatively short distance one is able to drive on a single charge. 2019 Prius Prime 55 city/53 hwy/54 combined mpg estimates determined by Toyota.

Conservation biologists are dealing with and have published evidence from all corners of the planet indicating that humanity may be causing the sixth and fastest planetary extinction event. It has been suggested that an unprecedented number of species is becoming extinct in what is known as the Holocene extinction event. The global extinction rate may be approximately 1,000 times higher than the natural background extinction rate. It is estimated that two-thirds of all mammal genera and one-half of all mammal species weighing at least 44 kilograms have gone extinct in the last 50,000 years. The Global Amphibian Assessment reports that amphibians are declining on a global scale faster than any other vertebrate group, with over 32% of all surviving species being threatened with extinction. The surviving populations are in continual decline in 43% of those that are threatened.


Acidification Of The Oceans


Adverse effects may be indirectly related to acid rain, like the acid’s effects on soil or high concentration of gaseous precursors to acid rain. High altitude forests are especially vulnerable as they are often surrounded by clouds and fog which are more acidic than rain. Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms as well as causing damage to buildings and having impacts on human health. Nitric acid in rainwater is an important source of fixed nitrogen for plant life, and is also produced by electrical activity in the atmosphere such as lightning. In 1981, the National Academy of Sciences was looking into research about the controversial issues regarding acid rain. President Ronald Reagan did not place a huge amount of attention on the issues of acid rain until his personal visit to Canada and confirmed that Canadian border suffered from the drifting pollution from smokestacks in Midwest of US.
