The result of this analysis is that the top 50 crops are sufficient to characterize the world agricultural system in its production of protein, fat, carbohydrates, and kcal for the world population. So, how many kcal does the global food system produce? Just over 10 16 kcal. How many kcal are needed to feed one billions persons? The answer, from my previous post, is 10 15 kcal â 10 6 kcal per person per year (2740 kcal per person per day) times 10 9 persons. So at 10 16 kcal, the world agricultural system produces enough kcal to feed 10 billion persons.
A Registered Nurse (RN) earns an average wage of $28.47 per hour.
Women dominate nursing field, yet men make more. Even in an occupation that women overwhelmingly dominate, they still earn less than men, a study of nurses found.The gender gap for registered nurses' salaries amounts to a little over $5,000 yearly on average and it hasn't budged in more than 20 years.OMEN OUTEARNED. The average 2013 salary for male nurses was about $70,000, versus about $60,000 for women. Taking into account factors that influence salary including geographic location, nursing specialty and years of experience trimmed that $10,000 pay gap by about half.
