#Ecologia - BIODIVERSITY AND ECOSYSTEM FUNCTIONING - Biodiversity is the variation of life forms within a given ecosystem or for the entire Earth - Biodiversity is often used as a measure of the ecosystem health.

#Power to the Poorest - An estimated 1.2 billion people worldwide, including 550 million in Africa and 400 million in India, have no access to electricity. Most live in rural areas where the population is sparse and incomes are low, making it uneconomical to connect homes and businesses to a grid. Nor is it feasible to generate power locally with a diesel unit, owing to high fuel costs and the need for substantial initial investment.
#Environment - Climate-Model Misgivings - The credibility of climate scientists has taken a number of hits lately, with climate models having failed to predict the “pause” in global warming over the last decade or last year’s increase in Antarctic sea ice. Even with the benefit of hindsight, the Intergovernmental Panel on Climate Change has struggled to explain recent developments.
