Air pollution is an example of a environmental hazard. Air pollution is caused by the burning of fossil fuels. Pollution is also caused by the gases released from factories and cars. Air pollution leads to many breathing problems, one being asthma. It can also cause global warming. Last, some of the harmful chemicals can cause acid rain. These are a few of the many effects of air pollution.

Explanation:
I think that makes sense. Its been a while since i have done this type of stuff
Recommended rates of potash for grazed grass are 60kg/ha and 30kg/ha of K2O for soil index 0 and 1 respectively. For soils with higher soil fertility levels no potash required.
Very large quantities of potash are removed in grass silage which must be replaced to maintain soil fertility and yield potential. The following is guide to typical potash offtakes from multi-cut silage systems.Low soil magnesium levels will affect grass yield as well as mineral balance in the animal. Apply 50-100 kg/ha MgO every three to four years at Mg index 0. Yield response is less certain at index 1 but magnesium application is justified in terms of insurance for grass yield and mineral balance for the animal, to maintain a soil magnesium index of 2.
Where lime is required and Mg levels are 0 and 1, use magnesian limestone as the most cost effective magnesium source. Where pH is satisfactory, specific magnesium fertilisers (see table below) should be used for soil improvement. Use water soluble forms of magnesium where rapid plant uptake is required.
South America is a continent that has a variety of climates, but the predominant one is the tropical climate.
The tropical climates are climates that appear on and in close proximity tot he Equator, and they are not monotone, but instead differ from one another. From the tropical climates that dominate the South American continent, the most widespread are the tropical rainforest and the tropical grasslands, which account for most of the tropical climates, with the tropical semiarid and tropical arid climates occupying much smaller areas on the continent, mostly alongside the Pacific coastline.
The Amazon rainforest is the trademark of South America, and it is the biggest tropical rainforest in the world, occupying huge portion of the northern half of the continent, with the tropical grasslands occupying large ares both north and south of the Amazon.
The answer is - Ocean.
All of the oceans in the world are connected, so they practically represent one huge body of water, which is by far the biggest in the planet, and is also a body of water that consist salt, thus it has salty water.
The oceans have sub-divisions, smaller than them, called seas. They range a lot in size, while some are huge, others are smaller than some big lakes. They represent a remote, peripheral part of the oceans, naturally surrounded by some geographical land forms, still they are part of the oceans.
