The article describes the effects of hypoxia, a lack of dissolved oxygen in the water, on the habitat of the Long Island Sound, an estuary where there is a mixing of freshwater, marine and anadromous species and the multisectoral alliance combined with federal efforts to reverse the sound's ecological decline. It cites that hypoxia results from the nitrogen that is released by sewage-treatment plants exacerbated by billions of contaminated water from farms, lawns, roads, illegal connections to the sanitary sewer system and overworked septic systems have contributed to the sound's toxicity which have killed certain species. With the coalition of advocates to save the sound, U.S. Congress rewarded its efforts and passed the Long Island Sound Restoration Act to improve water quality.

The article presents ways in which people can protect boreal forests. To help preserve the boreal forest, one should cancel his catalogue subscriptions and shop online instead. Seventeen billion catalogues are mailed annually, despite an average response rate of only 2.5 percent. Less than 5 percent of those catalogues contain post-consumer recycled material, and most get at least some of their virgin fiber from the boreal forest. Another simple step consumers can take for the boreal forest is to buy recycled tissue and printing paper. Kimberly-Clark Corp., which produces Kleenex, Scott, Viva, and Cottonelle brand tissues, toilet paper, and paper towels, uses no recycled content in many of its disposable products, and it cuts down more than a million cubic yards of boreal forest a year.

The article focuses on the nature of a chicken egg. In the week leading up to the laying of a chicken egg, a yolk forms in a mother bird's ovary. It then drops into the oviduct, where it is fertilized by stored sperm. Next albumen, or egg white, is deposited around the yolk. The shell forms within the following 24 hours, after which the mother pushes the egg out and into the nest. Chickens have a 21-day incubation period. Some small songbirds complete their embryonic development in as few as 11 days, while the wandering albatross can take as long as 81 days.
