About Water
97% of the water on the Earth is salt water. However, only 3% percent is fresh water; slightly over 2/3 of this is frozen in glaciers and polar ice caps.
The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air.
Fresh water is a renewable resource
Surface water
Surface water is water in a river, lake or fresh water wetland. Surface water is naturally replenished by precipitation and naturally lost through discharge to the oceans, evaporation, and sub-surface seepage
Ground Water
Sub-surface water, or groundwater, is fresh water located in the pore space of soil and rocks. It is also water that is flowing within aquifers below the water table
Surface and ground water sources are pinpointed, highlighting the genuine sources of public water supply. In further slides, factors governing the selection of a particular source of supply are pointed out; and finally, the necessity of water to mankind is herein.

Water is the most precious gift of nature. It has no taste, no smell and no colour. It is found everywhere and the other name of it is life. We find it in tanks, ponds, wells, rivers and springs. Almost three-fourth of the earth is water. We should conserve and save water so as to protect the water environment.
The demand of seaweeds nowadays have been increasing. In order to supply the needs, background on seaweeds culture is very important. We must know how to culture seaweeds, handle it with care, the methods to be used, and the environmental factors that may affect the growth of seaweeds.

Water is the most important source of life on earth. Impure and polluted water have become a serious threat to human sustenance.Contaminated water is the major cause of serious diseases in both humans and animals.That is why it is very important to be cautious about the type of water you are drinking.
Freshwater is relatively pure and contains few dissolved salts.
Earth has a precious layer of water—most of it saltwater—covering about 71% of the earth’s surface.
Water is an irreplaceable chemical with unique properties that keep us and other forms of life alive. A person could survive for several weeks without food, but for only a few days without water
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).

what is the future of Pi Network currency.DOT TECH
The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.

• Real GDP growth slowed down due to problems with access to electricity caused by the destruction of manoeuvrable electricity generation by Russian drones and missiles.
• Exports and imports continued growing due to better logistics through the Ukrainian sea corridor and road. Polish farmers and drivers stopped blocking borders at the end of April.
• In April, both the Tax and Customs Services over-executed the revenue plan. Moreover, the NBU transferred twice the planned profit to the budget.
• The European side approved the Ukraine Plan, which the government adopted to determine indicators for the Ukraine Facility. That approval will allow Ukraine to receive a EUR 1.9 bn loan from the EU in May. At the same time, the EU provided Ukraine with a EUR 1.5 bn loan in April, as the government fulfilled five indicators under the Ukraine Plan.
• The USA has finally approved an aid package for Ukraine, which includes USD 7.8 bn of budget support; however, the conditions and timing of the assistance are still unknown.
• As in March, annual consumer inflation amounted to 3.2% yoy in April.
• At the April monetary policy meeting, the NBU again reduced the key policy rate from 14.5% to 13.5% per annum.
• Over the past four weeks, the hryvnia exchange rate has stabilized in the UAH 39-40 per USD range.

Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.
How can i find a pi vendor/merchant?
Well for those who haven't traded with a pi merchant or who don't already have one. I will leave the telegram id of my personal pi merchant who i trade pi with.

Distribute of water on Earth
6. SOURCE OF DRINKING WATER
1. Surface water
5. Desalination
4. Rain water3. Ground water
2. Frozen water
7. Surface water:
Surface water is water in a river, lake or fresh
water wetland. Surface water is naturally
replenished by precipitation and naturally lost
through discharge to the oceans, evaporation, and
sub-surface seepage
8. Sub-surface water, or groundwater, is
fresh water located in the pore space
of soil and rocks. It is also water that is
flowing within aquifers below the water
table
Ground Water:
9. . Sometimes it is useful to make a distinction between sub-
surface water that is closely associated with surface water and
deep sub-surface water in an aquifer (sometimes called "fossil
water").
10. • Desalination:
Desalination is an artificial process by which saline water (generally sea
water) is converted to fresh water. The most common desalination
processes are distillation and reverse osmosis. Desalination is
currently expensive compared to most alternative sources of water,
and only a very small fraction of total human use is satisfied by
desalination. It is only economically practical for high-valued uses
(such as household and industrial uses) in arid areas. The most
extensive use is in the Persian Gulf.
11. Frozen Water:
Several schemes have been
proposed to make use of
icebergs as a water source,
however to date this has
only been done for novelty
purposes. Glacier runoff is
considered to be surface
water.

12. TYPES OF DRINKING WATR
TAP WATER
tap water is generally safe to drink, but it may be heavily filtered and
treated with chemicals to reduce the presence of parasites. Tap water
may contain heavy chlorine levels to help maintain micro-biological
safety during storage, and transit, through water mains, tanks and
pipes
The majority of tap water will have been used in some capacity before,
so it is recycled, re-treated and re-filtered before consumption.
Consequently, tap water can taste unpleasant and some customers worry
about treatment by-products. The presence of parasites such as
cryptosporidium is not unknown in tap water, which results in a number
of requests to ‘boil water’ each year. Cryptosporidium, a bug found in
surface water sources such as those taken from rivers and stream-fed
reservoirs, can occasionally get through filters and isn’t removed by
chlorine.
13. FILTERED WATER
There are a number of filtration and bottle filling
systems available today. The filtered water you
drink is typically tap water that has been
filtered to remove the chlorine residue – simply
to improve the taste. Many of the filters used
do not protect against contaminants such as
the parasites Cryptosporidium and Giardia
Absolute 1 micron filtration removes any particles that are
larger than 1 micron in size. This filtration leaves minerals in
water.
Ozonation is used by bottled water companies instead of
chlorine to eliminate baceria. Ozonation does not change the
mineral content of your water
14. • These types of water can originate from a mixture of
sources; some of the well packaged and marketed
bottled waters are merely re-processed tap water.
Waters labelled as ‘purified’ or ‘vapour distilled’ are
actually tap water that has gone through further
processing, such as reverse osmosis, to make them
suitable for sale as bottled drinking water.
• This process will remove most of the mineral content,
notably calcium. So much so that in the UK the addition
of calcium back to the water is compulsory, on the
advice of the medical authorities, due to concerns over
heart disease. Many of these waters are ozonated,
which can result in harmful by-products like bromates.
These waters are not renowned for their sensory
stimulation qualities. Interestingly, these waters can
appear under one brand name, but can be mutli-
sourced in different countries from across the world
BOTTLED DRINKING WATER
15. SPRING WATER
Like natural mineral water, waters that are
labelled ‘spring water’ must originate from an
officially recognised source. However, unlike
natural mineral water they do not undergo the
intensive 2 year recognition and regulatory
process, and until recently did not have to be
bottled at source.
Spring water is microbiologically wholesome,
naturally free from pollution and harmful
organisms but may use micro-filtration and UV
treatments. It does not need to demonstrate a
stable composition, and in essence is judged on
the day it is bottled, which means that the
composition can change.
16. Natural Mineral Water
• Natural mineral water must originate
from an officially recognised single
source and must be bottled at that
location. Before water can be officially
recognised as natural mineral water, it
must be demonstrated to the UK
authorities, through regular and
frequent micro-biological testing for 2
years, that the source is protected from
all risk of pollution and that the
composition, temperature and other
essential characteristics remain stable.
The water is then subjected to ongoing
statutory testing and continual
maintenance for the duration of its
continued extraction from its source
