Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Saltwater accounts for 97.5% of this amount, whereas fresh water accounts for only 2.5%. Of this fresh water, 68.9% is in the form of ice and permanent snow cover in the Arctic, the Antarctic and mountain glaciers; 30.8% is in the form of fresh groundwater; and only 0.3% of the fresh water on Earth is in easily accessible lakes, reservoirs and ...
Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always potable water, that is, water safe to drink by humans. Much of the earth's fresh water (on the surface and groundwater) is to a substantial degree unsuitable for human consumption without treatment.
A mere 0.014% of all water on Earth is both fresh and easily accessible. [34] Of the remaining water, 97% is saline, and a little less than 3% is difficult to access. The fresh water available to us on the planet is around 1% of the total water on earth. [35] The total amount of easily accessible freshwater on Earth is 14,000 cubic kilometers.
The findings challenge the existing theory that the planet was completely covered by ocean four billion years ago.

2. Baby Food. One might think that a product advertised for infants and young children would be safe to eat. Alas, it's shocking how much food marketed to kids contains lead.
These two islands are about 100 miles away from any others, isolated and surrounded by nothing but water. Wolf and Darwin islands are small — less than a square mile each — and lack any beaches.
