In business industries all over the world, one of the hottest trends is to move from paper to cloud based management systems for running all operations of the company. But a lot of people tend to take a step back from it and it is completely justified as they are not entirely used about the e purchasing or cloud based procurement system or software. You might even have a bunch of unanswered questions too, right? If that is the case then you should do a thorough research, ask experts and look into various testimonials before making any decision on this particular topic. With that said, following are some of the frequently asked questions related to cloud based purchasing and procurement systems that you can read all about, check them out below.
Shopping on Vendor Website
Since you are buying a cloud based system, essentially you will have to make the payment on vendor website. Apart from that, you will also be doing interval payments to them for the same purpose.
Restriction on Visibility
If you want, you can have total transparency when it comes to spending, however, if you do not want everyone to have the same kind of access then you can customize and go for selective transparency as well i.e. you can restrict the visibility to a few people. Since all company spending are not necessarily important for each and every employee to know about any way so you can personally get in touch with the vendor and tell them about your requirements and they will do so according to your needs and requirements. This is not only applicable for spending and income but also about other reports that are uploaded on the cloud and are sensitive in nature.
Global warming has become a hot topic lately (no pun intended), people all across the world are concerned about how it will shape the future of our planets and what should we do in order to bring it under control. Unfortunately, a cast majority of us still are not ready to take global warming seriously, some people are even going as far as stating that it is a made up phenomenon. We have plenty of evidence that suggests that global warming is indeed a real thing and it is already having devastating impacts on our planet, and now, thanks to scientific research, we can get a pretty good idea of just how destructive global warming can be.
Scientists have found out that our planet has undergone global warming previously, approximately 440 million years ago, the world underwent temperature changes that resulted in mass extinctions across the planet, and the scariest part is that the temperature changes that we are dealing with right now are much more intense than what occurred 440 million years ago.
We now also know that what exactly triggered a global warming event millions of years ago; it was caused by a decrease in oxygen and increase in carbon dioxide in the environment. Animals started showing up on Earth around 540 million years ago, their sudden spread throughout the world’s oceans resulted in our atmosphere becoming unbalanced, according to scientists; Earth’s seabed started undergoing bioturbation, a process in which small lifeforms begin recycling dead organic material situated on the sea floor.
Around 520 million years ago, small lifeforms of all kinds started spreading rapidly in the then nutrient rich seafloors, they had an ample amount of nourishment that allowed them to multiply rapidly. As they fed on whatever the sea floor had to offer, they consumed oxygen and produced carbon dioxide in the process. Their activities led to the ratio of carbon dioxide and oxygen in the atmosphere becoming disturbed, this, coupled with their rapid evolution resulted in a rapid increase in carbon dioxide, leading to a phenomenon that we call global warming.
Scientists managed to figure this out thanks to what data we already had on hand and a number of mathematical models that were crafted to identify and highlight all the related variables. Thanks to their efforts, we managed to figure out the leading cause behind several mass extinction events that took place back in that time period, and more importantly, we figured out that temperature rises millions of years ago were caused by factors that are present today as well.
We are on the brink of another global warming crisis thanks to the insane amount of carbon dioxide (and other greenhouse gases) that we regularly pump into the atmosphere. Fortunately, it still is not too late for us, unlike the worm like creatures of pre-historic times, we have the ability to bring our excess emissions under control and prevent our atmosphere from falling apart.
Miami’s once beautiful shores may no longer be visit-able in the future, unless you bring along a snorkel. Miami’s greatest attraction has always been its seaside; beautiful sandy beaches and loads of resorts that enable people to get in touch with the ocean, however, this city has always had a hard time dealing with floods, storms and rising tides. Lately, Miami’s population has started to face even more trouble from the ocean as water levels have begun to rise, people living close to the coastline have had an especially hard time as their routine is regularly disrupted by rains, floods and the ocean tides.
In fact, the coastline has been shrinking gradually for a while now, as a result, communities that have been inhabiting the coastline till now are being forced to look for new places to live as the ocean is steadily swallowing up their homes. Small businesses and homes lining the coastline have had to deal with the most trouble, due to the fact that most of them come from low income households and now they have to look for living spaces in more elevated areas. The worst part is that many displaced communities (such as little Haiti) are unable to keep up with the rising costs of living in more elevated areas.
Naturally, this increase in demand for land away from the coastline has resulted in real estate prices going even higher, the residents of Miami are bound to face difficult times in the coming days due to financial and societal issues being brought about by global warming. There have also been reports of a rise in water borne diseases as more waste water is beginning to seep into the ocean, which gets brought back to the coast during high tide.
By 2045, one fifth of Miami is expected to go underwater as sea levels are projected to rise by 1 foot. Miami is going to have an especially hard time with rising sea levels due to the fact that its coast’s bedrock consists of large amounts of limestone. Limestone is highly porous, meaning that it can allow salt water to seep further into the ground and start mixing with the area’s ground water reserves. High levels of salt water intrusion in the area’s ground water will result in its coastal plant life becoming less dense, this in turn, will lessen the coast’s ability to slow down strong winds coming from the ocean.
Basically, global warming is going to strike Miami from multiple angles, the city’s economy will suffer due to a loss of real estate around the coast, a decrease in tourist activity, a rise in health problems and the coast’s natural defences against flooding and storms going down. Fortunately, 2045 is still far off and we can do something about Miami’s future if we act right now, global warming is a daunting phenomenon, but we can prevent it from taking place by being more responsible.
Hawaii’s coral reef has become victim to a very strange phenomenon that has resulted in scientists banning the use of sunscreen in the area. Corals in Hawaii have been exhibiting high amounts of stress that is causing them to envelop themselves in their exoskeletons and dying off. The exact reason behind this behaviour is still uncertain, but researchers have managed to figure out that certain chemicals present in sunscreen are responsible for this kind of behaviour amongst corals. While they are still uncertain whether these chemicals are the leading cause of corals dying, the government of Hawaii has decided to ban the use of these chemicals until they get a better idea of what is going on.
This decision has resulted in outrage amongst people worrying about getting skin burned or developing skin cancer, but the government has decided to take this step in order to preserve its coral reefs.
We know that when a coral undergoes stress, it begins to “ossify”, meaning that is covers itself in its own bone material in order to protect itself, however, if the stress does not go away, a coral eventually ossifies all the way through and dies. The reason why researchers believe that sunscreen is responsible for coral stress is because oxybenzone and octinoxate (the two major culprits present in sunscreen) have previously been known for causing corals to bleach themselves.
Researchers believe that oxybenzone triggers a hormonal disruption in corals that makes them unable to properly regulate their skeletons, oxybenzone is present in about 70% of suncscreens used in USA. Octinoxate is not as commonly found as oxybenzone, but it is known for leading to coral bleaching.
Oxybenzone is the main culprit so far, due to the fact that there is scientific evidence indicating that this chemical causes a disruption in various bodily hormones in mammals, including estrogen. A high level of estrogen in the body results in the body producing excessive amounts of bone tissue, if oxybenzone has similar effects on coral hormones then this could be one way in which it is forcing corals to kill themselves. Another way in which oxybenzone is causing corals to die is by disrupting their ability to send signals throughout their body.
While we can make educated guesses, sadly we simply do not know enough to be able to state what exactly is causing corals to die like this and how is it managing it. Even the best coral researchers in the world are currently only able to hypothesis about the situation, all we can do at the moment is find a better alternative for sunscreen. The bill for banning sunscreen in Hawaii will become active in 2021, so anyone who wants to spend time on Hawaii’s beaches still have plenty of time to look for alternative sunscreens or simply find other ways of protecting their skin.
Corals are an important part of the shallow sea ecosystem, which is why it is highly important to safeguard them and prevent them from dying out.
