Lack of water



The daily struggle for water is something the people are suffering from in many countries of the world, for example, we will talk about the Republic of Yemen. Children and women crowd around public faucets to collect water and return to the homes and for daily use. A lot of people aren’t able to pay water fees. The statistics shows each Yemeni only has access to about 140m3 comparing to the other Middle East countries where the average of each person is 1000m3. Some of those reasons were random digging and using the traditional way in the irrigation. Rapid intervention by the government is needed to solve this problem. If the government don’t put this problem on the top of the list of government priorities Sana'a, which is the city suffering most from this situation, will be the first capital in the world to run out of a viable water supply. There are some solutions to end this problem like to drill or truck in water. In my opinion the best solution is to ban qat cultivation which is one of the main reasons for this problem because it consumes large amounts of water In contrast, on the other hand there is no product to improve the standard of living.

The corals on the Gulf


We want to look for ways in which coral survives the deadly heat in the Gulf. We found that the coral lives in coexistence with the type of algae that live in the tissues of coral; these algae produce sugars that provide approximately 90 percent of the coral’s energy; the coral in return offers her coral shelter and nutrients such as nitrogen and phosphorus. How the coral breed may be a solution for what we want to discover. One way is Fragmentation, also called vegetative propagation; this is when a piece of coral breaks off, rolls across the sand, lands somewhere else and starts growing. Now we all are working to find solutions to provide a suitable environment for live coral reproduction and prevent it from extinction. Knowing that we must keep in mind that temperatures continues to grow, especially in the Gulf region and its neighboring regions of similar climate.
