'''Ecological Debt Day''', also known as '''Earth Overshoot Day''', is the (claimed) approximate calendar date on which humanity’s resource consumption for the year exceeds Earth’s capacity to regenerate those resources that year. Ecological Debt Day is calculated by dividing the world biocapacity (the amount of natural resources generated by Earth that year), by the world Ecological Footprint (humanity’s consumption of Earth’s natural resources for that year), and multiplying by 365, the number of days in one Gregorian calendar year: | |||
:<math>( \text{World Biocapacity} / \text{World Ecological Footprint} ) \times 365 = \text{Ecological Debt Day}</math> | |||
When viewed through an economic perspective, Ecological Debt Day represents the day in which humanity enters deficit spending, scientifically termed “[[overshoot]]”. It is a rough estimate of time and resource trends, of measuring the gap between human demand for ecological resources and services, and how much Earth can provide, made by the Footprintnetwork organization.<ref name=EOD>[http://www.footprintnetwork.org/en/index.php/GFN/page/earth_overshoot_day/ Earth Overshoot Day is coming!] Global Footprint Network.

Earth Overshoot Day campaign
Earth Overshoot Day draws on the fact that due to finite resources, humanity's recent trend of consuming more resources than Earth can produce each year constitutes an unsustainable path termed “overshoot.” Earth Overshoot Day is conveyed using economic imagery of monetary debt as a means of reaching the general public rather than just the scientific community. The goal of Global Footprint Network’s Earth Overshoot campaign is to bring the idea of limited global resources into people’s minds. The basic question is: What happens when an infinite-growth economy runs into a finite planet?[1]

They are among the world's 10 biggest webhosting business. According to their website, they host well over 2,500,000 domains. They have likewise been placed number 21 on the Inc 5000 fastest growing business in America. From the years 2005 to 2008, HostGator achieved a 900 % increase in revenue.

In our viewpoint, to be effective in this extremely competitive field, you best offer to your customers an appealing value proposal. That is not constantly the case. Some of the hosting companies struggle with effectively managing dependability, services/tools, customer relations, and cost. HostGator is most likely the closest thing that you will find to pulling the bunny out of the hat. For just $4.95 a month they offer a long list of features, tools, and services. Each hosting account comes geared up with well over 4,500 website templates. HostGator is likewise well understood for the fantastic unlimited diskspace and bandwidth they provide. They provide an extremely flexible and individual friendly control board, unlimited sub domains, FTP accounts, and e-mail accounts and just a laundry list of other functions. Go take a look for yourself. Not to discuss the $50 free in Goggle AdWords credit. Let me be cautious below so as not to let predisposition creep into my evaluation. These men provide a very durable value proposal when comparing every little thing that is very important to the web designer. That is the conservative way of explaining it.
Control board
HostGator makes use of an extremely simple to navigate cPanel. The HostGator cPanel is one of the many user friendly full featured control panels. Simply click on their link below and you can really demo their cPanel in order to get "feel" for how it operates.
