1.8 billion people who have access to a water source within 1 kilometre, but not in their house or yard, consume around 20 litres per day. In the United Kingdom the average person uses more than 50 litres of water a day flushing toilets (where average daily water usage is about 150 liters a day. The highest average water use in the world is in the US, at 600 liters day.)
Primary energy consumption of India is the third-largest after China and the US with 5.3% global share in the year 2015.[220] Coal and crude oil together account for 85% of the primary energy consumption of India. India's oil reserves meet 25% of the country's domestic oil demand.[209][221] As of April 2015, India's total proven crude oil reserves are 763.476 million metric tons, while gas reserves stood at 1,490 billion cubic metres (53 trillion cubic feet).[222] Oil and natural gas fields are located offshore at Bombay High, Krishna Godavari Basin and the Cauvery Delta, and onshore mainly in the states of Assam, Gujarat and Rajasthan. India is the fourth-largest consumer of oil and net oil imports were nearly ₹820,000 crore (US$110 billion) in 2014–15,[222] which had an adverse effect on the country's current account deficit. The petroleum industry in India mostly consists of public sector companies such as Oil and Natural Gas Corporation (ONGC), Hindustan Petroleum Corporation Limited (HPCL), Bharat Petroleum Corporation Limited (BPCL) and Indian Oil Corporation Limited (IOCL). There are some major private Indian companies in the oil sector such as Reliance Industries Limited (RIL) which operates the world's largest oil refining complex.[223]
There are a lot of article sites out there that share revenue, but my favorite (and it’s where I earn most of my article writing income) is InfoBarrel, which you’re very familiar with if you’ve been following my blog for awhile.  If you’re up for a very ambitious challenge, you can read about the one I wrote for earning $2,000+ per month with article writing.  The top InfoBarrel writers currently earn at least $2,000 per month.
Real-estate crowdfunding ($9,600 a year): Once I sold my SF rental, it was natural to reinvest some of the proceeds into real-estate crowdfunding to keep sector exposure. I didn't invest a lot in some of my favorite real-estate investment trusts because I felt a rising interest-rate environment would be a stronger headwind for REITs. But if I could be more surgical with my real-estate investments by identifying specific investments in stronger employment-growth markets, I thought I could do better.
I would throw in some caution here: if your spouse works at the same company, or in the same industry as you, you are not diversified, and should something happen, you could be in a world of hurt.  Companies do go out of business, companies do lay employees off.  There is nothing wrong with working together, but realize that you are not diversified and you should be trying to maximize other income streams as a result.

Millennium Development Goals Report 2007 . The report importantly notes that As high as this number seems, surveys show that it underestimates the actual number of children who, though enrolled, are not attending school. Moreover, neither enrolment nor attendance figures reflect children who do not attend school regularly. To make matters worse, official data are not usually available from countries in conflict or post-conflict situations. If data from these countries were reflected in global estimates, the enrolment picture would be even less optimistic.

It is our duty now to begin to lay the plans and determine the strategy for the winning of a lasting peace and the establishment of an American standard of living higher than ever before known. We cannot be content, no matter how high that general standard of living may be, if some fraction of our people—whether it be one-third or one-fifth or one-tenth—is ill-fed, ill-clothed, ill-housed, and insecure.
Infectious diseases continue to blight the lives of the poor across the world. An estimated 40 million people are living with HIV/AIDS, with 3 million deaths in 2004.

In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
