The answer is rainforests. The destruction of rainforests can lead to global warming due to the accumulation of carbon dioxide as a greenhouse gas in the atmosphere. This is because rainforests are major carbon sinks because they sequester carbon dioxide from the atmosphere. One of the major rainforests that are facing the threat of human activities is the Amazon and Congo forests.
The answer is south america’s location atop the Nazca and South American plates of the circum-pacific belt. The circum-pacific belt is also known as the ‘ring of fire’ because there is a subduction zone in the region. The Cocos plate is subducting under the Caribbean Plate. This creates friction between the two plates with occasional release of high amounts of energies when a stuck region gets unstuck abruptly. This region accounts for approximately 90% of the world’s earthquakes.

Botswana is an African nation where over 23% of population is infected with HIV. The government introduced prevention, treatment and testing strategy to address this serious issue. The goal of this program is to bring HIV infections under control in the country and reduce the chances of further infections.
According to the ‘treat all’ program every person who is tested to be <em>HIV positive</em> is given immediate treatment. All infected persons are given free Anti Retroviral Treatment for a lifetime. The government’s active measures could successfully reduce the infections that spread from affected mother to infants.
Testing measures have changed form from voluntary testing to routine testing and then to compulsory testing. Compulsory testing is sometimes blamed for increasing the stigma about the disease. But these measures help the people to know their status and reduce the number of people living without knowing they are HIV positive.
If we have the intersection of the equator and the prime meridian as a starting point, and we move towards west, than the three oceans that we will encounter will be in the next order:
1. Atlantic Ocean; lies between Europe and Africa from one side (eastern borders), and North and South America on the other side (western borders). It is in fact our starting point.
2. Pacific Ocean; lies between Asia and Australia form one side (western borders), and North and South America from the other side (eastern borders).
3. Indian Ocean; lies between Southeast Asia and Australia (as its eastern borders) and Africa as its western border, and on the north it borders with South Asia.
The northernmost ocean on our planet is the Arctic Ocean, which is lying around the Arctic circle.
The southernmost ocean is the Southern Ocean which surrounds Antarctica with its waters.
