Increase in Rhino poaching in South Africa

Although there are laws against poaching and hunting of endangered animals, it still doesn't stop people from doing it. In South Africa, 1,000 Rhinos were killed last year for their horns. Horns are very valuable to countries such as China and Vietnam because it contains the key ingredient for traditional medicine. Elephants are being killed excessively as well for their tusks. Even though it is inevitable that people will illegally hunt and kill these animals, it is very sad that the numbers are not only high but they have increased dramatically. The demand for these animal's bodies are so high and it puts their future in great harm.

Colorado River Drought Forces a Painful Reckoning for States

The once very blue and abundant river, Lake Mead, is now trickling down to a murky brown water. Reservoir capacities are dwindling down to half and in order to use the rest of the water to its fullest, the water agencies are promoting less demanding appliances that require more water and recycling sewage effluent. Studies show that the next century shows a lot drier conditions and a possible end to the lakes and rivers around Nevada. Many things will be affected by this due to the fact that mostly everything runs with water and without water in these areas, slowly things will come to an end. In order to help prevent the absolute worst, throughout the 21st century, everyone will have to use less water.

Fishing technique known as trawling can sometimes be productive.

Trawling is a certain fishing method which is basically just an intense raking of the seabed. Usually, it is known to cause much damage to sea life but recently, scientists have studied and found that there are many potential benefits to it. Studies have shown that trawling can create better conditions for the fish. The trawling process usually catches the bigger fish but the smaller fish grow resistant to it and find their way around it which increases population for the smaller fish. Due to the larger population of smaller fish, the larger fish population also increases. Although this is a positive relation to trawling, this really occurs best when the trawling process isn't as intense.
