Pollution In New Zealand
Pollution is an Environmental issues in New Zealand, environmental issue in New Zealand with a number of measures being taken to reduce its severity. New Zealand is sometimes viewed as being "clean and green" but this can be refuted due to pollution levels, among other factors. New Zealand does have a relatively low air pollution level, but some areas have high levels of plastic pollution. Types Water pollution Water pollution in New Zealand varies depending on the level of development in the water catchment areas. In recent years concerns have been raised about the effect of intensification of Dairy farming in New Zealand, dairy farming on water quality. The Drying and Clean Streams Accord was established to address problems with water pollution due to dairy farming. Marine pollution Fertiliser runs off farms and yards into nearby rivers and streams, which carry it out to the ocean. It is also carried by the cloud and when it rains it drops in the ocean, which is carried by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Pollution In The Wairarapa
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ab ...

Christchurch
Christchurch ( ; mi, Ōtautahi) is the largest city in the South Island of New Zealand and the seat of the Canterbury Region. Christchurch lies on the South Island's east coast, just north of Banks Peninsula on Pegasus Bay. The Avon River / Ōtākaro flows through the centre of the city, with an urban park along its banks. The city's territorial authority population is people, and includes a number of smaller urban areas as well as rural areas. The population of the urban area is people. Christchurch is the second-largest city by urban area population in New Zealand, after Auckland. It is the major urban area of an emerging sub-region known informally as Greater Christchurch. Notable smaller urban areas within this sub-region include Rangiora and Kaiapoi in Waimakariri District, north of the Waimakariri River, and Rolleston and Lincoln in Selwyn District to the south. The first inhabitants migrated to the area sometime between 1000 and 1250 AD. They hunted moa, which led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litter In New Zealand
Litter is a global issue and has a significant human impact on the environment. Litter is especially hazardous because it can enter ecosystems and harm a country's biodiversity. Litter is a prevalent environmental issue in New Zealand. New Zealanders are known to take pride in their 'clean green' image. A national survey conducted in December 2017 revealed that 99% of respondents considered the maintenance of New Zealand's 'clean green' image to be of importance. For these reasons the prevention of litter is considered to be of national importance. While New Zealand is considered an environmentally conscious country, it continues to encounter litter issues. Plastic items are recorded to be the most littered item in the country. Cigarette butts, consisting primarily of plastic, are the most littered item worldwide and are therefore also pervasive in New Zealand. Plastic Litter is a particularly harmful form of litter as it threatens the New Zealand environment and the wildlife th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticides In New Zealand
There is a high use of pesticides in New Zealand due predominantly to the large agricultural industry. Pesticides 1080 Sodium fluoroacetate, commonly known as 1080, is used in New Zealand to control animal pests, specifically the possum which threatens biodiversity and carries tuberculosus. Hunters fear that 1080 impacts on game animals, and some environmentalists have concerns about 1080 killing the very native fauna it is meant to save, and pollution of drinking water reservoirs with 1080 baits and poisoned animals. 2,4,5-T Manufacture of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) ceased in New Zealand in 1987 and it is no longer sold in New Zealand. 2,4-D 2,4-Dichlorophenoxyacetic acid (2,4-D) is used in New Zealand and the Pesticides Board has decided not to prohibit the use of the chemical. DDT DDT was used extensively for agricultural use in the 1950s and 1960s to control grass grub and porina moth. It was also used on lawns and for market gardens. Some 500 t ...

Environment Of New Zealand
The environment of New Zealand is characterised by an endemic flora and fauna which has evolved in near isolation from the rest of the world. The main islands of New Zealand span two biomes, temperate and subtropical, complicated by large mountainous areas above the tree line.Walter, H. & Breckle, S-W. (2002). ''Walter's Vegetation of the Earth: The Ecological Systems of the Geo-Biosphere''. New York: Springer-Verlag, p. 86 There are also New Zealand Subantarctic Islands, numerous smaller islands which extend into the subantarctic. The prevailing weather systems bring significantly more rain to the west of the country. New Zealand's territorial waters cover a much larger area than its landmass and extend over the continental shelf and abyssal plateau in the South Pacific Ocean, Tasman Sea and Southern ocean. Historically having an isolated and endemic ecosystem far into modernity, the arrival of Polynesians about 1300 AD and then later European settlers began to have significa ...

Resource Management Act 1991
The Resource Management Act (RMA) passed in 1991 in New Zealand is a significant, and at times, controversial Act of Parliament. The RMA promotes the sustainable management of natural and physical resources such as land, air and water. New Zealand's Ministry for the Environment describes the RMA as New Zealand's principal legislation for environmental management. The RMA and the decisions made under it by district and regional councils and in courts affect both individuals and businesses in large numbers, and often in very tangible ways. The Act has variously been attacked for being ineffective in managing adverse environmental effects, or overly time-consuming and expensive and concerned with bureaucratic restrictions on legitimate economic activities. In February 2021, the Government confirmed that the RMA is to be replaced by three separate acts. These will be the Natural and Built Environment Bill (NBA), the Strategic Planning Bill (SPA), and the Climate Change Adaptat ...

Kyoto Protocol
The Kyoto Protocol was an international treaty which extended the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that (part one) global warming is occurring and (part two) that human-made CO2 emissions are driving it. The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February 2005. There were 192 parties (Canada withdrew from the protocol, effective December 2012) to the Protocol in 2020. The Kyoto Protocol implemented the objective of the UNFCCC to reduce the onset of global warming by reducing greenhouse gas concentrations in the atmosphere to "a level that would prevent dangerous anthropogenic interference with the climate system" (Article 2). The Kyoto Protocol applied to the seven greenhouse gases listed in Annex A: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perflu ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Smog
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words ''smoke'' and '' fog'' to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions. Smog is often categorized as being either summer smog or winter smog. Summer smog is primarily associated with the photochemical formation of ozone. During the summer season when the temperatures are warmer and there is more sunlight present, photochemical smog is the dominant type of smog formation. Du ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...

Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorganic ...
