ENA 7 is an optional course and it deals with environmental matters. You are welcome to explore the site and its links even if you don't take the course. I find this topic extremely interesting and important.

  • Let's start with YouTube: Video of The International Year of Biodiversity 2010:

"Freshwater makes up a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. In essence, only 0.007 percent of the planet's water is available to fuel and feed its 6.8 billion people."

(Also, please pay attention to the expressions of "graphic language": an increase or a decrease in something (the change might be e.g. sharp/dramatic/significant/moderate/steady). Research or statistics may demonstrate/show/reveal something, if it is certain. But if there is some doubt or uncertainty about the matter, and the writer is merely interpreting, then the figures or research suggest/imply/indicate something.)

"In Brazil, which houses 30 percent of the remaining tropical rain forest on Earth, more than 50,000 square miles of rain forest were lost to deforestation between 2000 and 2005. Biologists worry about the long-term consequences. Drought may be one. Some rain forests, including the Amazon, began experiencing drought in the 1990s, possibly due to deforestation and global warming."
