leads to local famine and cholera outbreaks. Madagascar's western coast, mangrove forests are particularly susceptible to any increase in sea levels. Although warmer ocean temperatures caused by global climate change have been recorded in northern Madagascar, the effects of this change on the coral reefs in the region have been mitigated, at least temporarily, by cooler water from deep ocean currents. Madagascar's unique flora and fauna are also susceptible to climate change. For example, reduced rainfall has negatively affected endangered sifaka lemur populations. The impact of climate change and global warming in Madagascar is exacerbated by deforestation resulting from increased population and unsustainable swidden farming and logging that has reduced forest cover and increased desertification, causing higher temperatures, lower humidity, and diminishing annual rainfall.

Efforts to reduce the effect of climate change and global warming on Madagascar's flora and fauna include the U.S. Agency for International Development's attempt to reduce brush fires, which, in addition to destroying vegetation, release carbon into the atmosphere. The Wildlife Conservation Society, Conservation International, and the government of Madagascar's Makira Forest Project seek to protect over 300,000 hectares of rainforest in northeastern Madagascar. It is hoped that the Makira Forest will offset 9.5 million tons of carbon dioxide (CO2) over 30 years through carbon sequestration, preserve habitat for threatened species, and provide economic opportunities for local indigenous communities.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
