Not enough water distribution

In the Environmental Managment class we are studying the water cycle. We were asked to write a paragraph about distribution of water and why it is important. Here is my paragraph.

All over the world there is water, but the distribution of fresh water is a big problem. Many countries are available to have rich amount of it, for example Russia is very large, having plenty of land for the rain to fall on. Canada, USA, China and Brazil are also countries that have large areas for water. Brazil have 5190 km of amount of renewable fresh water resources per year. The rainfall fill rivers and underground stores, however precipitation itself varies greatly from place to place.
Water-poor countries are dominated by desert countries. These countries are more likely to suffer water stress, this means worries over present and future water supplies. Poor countries manage to obtain water by taking out the salt of sea water, this process is called desalinisation. Also they pump up water to the surface from underground stores called aquifers.
Besides precipitation as a problem, population is another problem. Population is increasing rapidly as the water consumption. In the twentieth century world water use increased seven times. This growth is a huge problem because more water is going to be used for crops (irrigation), more water used in homes.
Finally, in my opinion this is a serious problem because we are overusing water. We can stop overusing it by for ex. when you brush your teeth, don't let the bobbin with running water. Another example is less time in the shower, just shower yourself and don't stay in the shower  for too long. By doing things like this we can save water.

Typhoon Haiyan

In the Environmental Managment class we talked about tropical cyclones, so we had to choose an specific cyclone and write where it happened, category and effects. I will write about Typhoon Haiyan.

On November 8, 2013 a tropical cyclone called Typhoon Haiyan, also known as Super Typhoon Yolanda devastated parts of Southeast Asia, Caroline Islands, Vietnam but mostly on the Philippines. It was one of the most devastating tropical cyclones and also a deadliest, killing at least 6,300 people in that country alone (Philippines) and in total 11 million people were affected. Haiyan is also the strongest storm recorded at landfall, and lasted till November 11, 2013. In January 2014, there were more bodies founded.

Typhoon Haiyan was a category 5 cyclone, with winds above 145 mph up to 195 mph.
In the Caroline Islands, it damaged several houses and cut down trees. They lost power to water or electricity. No people were killed, but 69 others were displaced by the storm.
In Southeast Asia, 20 villages were isolated by extensive flooding. Approximately 900 homes and 25,500 hectares of crops were destroyed, while 8,500 homes were damaged. Additionally, an estimated 3 million people were affected and 10 people died.
In Vietnam, there were very strong winds and 18 people were killed, while 4 others are missing.
In the Philippines, it caused catastrophic damage where cities and towns were largely destroyed. It was confirmed that over 6,300 people died. The actual death rate is unclear. 281.9 mm of rainfall recorded, which fell in under 12 hours. The airports were totally destroyed. There was not communication, no fish and nearly all structures were damaged. Also trees and cars. Flooding also extended for 1 km inland on the east coast of the province. Cities were all destroyed.

Environmental effects: the Typhoon hit a power barge, which caused an oil spill. The government replanted mangroves (like small trees) in coastal areas while preserving the remaining ones. Air quality test found out that benzene levels in affected areas reached near-zero parts per million, so people had to evacuate.
