"Reducing Pesticide Pollution of Aquatic Ecosystems"
july 16, 2008

Summary:The 5-year research goal of the Fisheries and Aquatic Resources Program addressed is to understand relationships between and among aquatic species habitats.

Every year millions of tons of pesticides are applied to soils in and around aquatic ecosystems that eventually pollute rivers, streams, lakes, wetlands, and municipal water supplies. "Agricultural soils are routinely sterilized with a chemical that destroys atmospheric ozone and increases the amount of ultraviolet light radiation which results in the degradation of aquatic systems." In an attempt to decrease pesticide pollution of aquatic ecosystems, a project has begun to develop to control agents to protect plants against fungal diseases. There are 3 objectives to this project. To understanding how fungi cause disease, understanding how plants that are symbiotic with certain fungi are resistant to fungal diseases, and develope an effective control system to protect plants against fungal diseases. If this project works its effectiveness could save many lifes of plants and small animals. It will also make the environment and water healthier.

"How climate change is hurting lakes"
Apr 21, 2009

Summary: Reports on Ontario's water quality shows climate change is impacting northern lakes.

The water quality is lengthening the ice-free season and potentially disrupting the lakes ecosystems."The Water Quality in Ontario 2008 Report examines the effect of phosphorus enrichment, toxic substances, acid deposition and climate change on provincial lakes and rivers." The climate change is making the ice-free season in the Lake increase by four weeks since the mid-1960s, leading to increased algae growth. Algae are the base of aquatic food webs and changes may have cascading effects to "higher levels of the food web". The aquatic system plays an affecet on many society's. Of lower parts of the food chain die off it will take a toll on other species moving up the chain and eventually affect humans aswell.

endangered species 2

"Quarter of the world's mammals on danger list"

Summary: "A report has revealed that at least 1,000 species are under serious threat largely due to the effects of human behavior."

The Red List of Endangered Species has announced in their latest report that over 1,000 species of mammals are at risk of extinction due to the destruction of habitats caused by hunting. After a study of 5,487 species, 1,141 were found to be at risk. This is such a high amount it is frightening. Humans are animals too you know? On day we may become the 1/5 that are endangered. This is what makes the concept of extinction so scary to me. One day the human race may be wiped out completely and never return.“Within our lifetime hundreds of species could be lost as a result of our own actions, a frightening sign of what is happening to the ecosystems where they live”.

"Saving Forests from the Group Up"
May 7, 2009
By Marsha Johnston

Summary: In 2000 a Forest Health Monitoring project began. Plots were surveyed on foot rather than photographs in Kenya.This was done so harm to wildlife could be directly monitored.

"When the farmer extends his field into the forest you can see it from the air, but you can’t see if they are cutting trees out of the forest,” he says. “Not many projects look at what’s going on inside the forest, whether human impact is happening that you can’t measure from the air.” Humans impact wildlife and forests habitats way to often because they are oblivious to the fact that its occurring.
Hertel’s painstaking legwork surveying overall forest health in eastern Africa has been a critical component of proving to local communities how protecting their forest also sustains their lives. This is good because eventually the loss of habitat leads to a loss of animals which leads to losses of species and losses of food ect.

"Wal-Mart vs. the Wilderness"
Sunday, May 3, 2009

Summary: A long time ago land was set aside as a national military park. However, just 21 percent of the battlefield is permanently protected; other key areas are privately held and vulnerable to development. This became apparent when Wal-Mart Stores Inc. announced plans to build a 138,000-square-foot superstore on land directly across the road from the national park.

This is sad because the land was intentionally set aside for national parks and preservation not cheap stores. It just seems like there should be a different location availbe somewhere for the store to open. If this is allowed to occur here it is sure to be a popular thing all over the nation. (development taking over national park land). If that is the case there will be no more land availibity. It will also disrupt many animals lifes now instead of a forest across the street their will be lots of dangerous cars, people, and pollutants.

"Coca-Cola donates money for recycling program on National Mall"
April 29, 2009
by Tierney Plumb

Summary: The Coca-Cola Co. is donating $1.1 million to revamp several U.S. national parks and to help launch a recycling program on the National Mall.

Money will support enhanced trail programs in seven national parks, which locally include George Washington Memorial Parkway. The Trust for the National Mall, the official partner of the NPS, said the comprehensive recycling and educational program for the National Mall’s 25 million annual visitors will kick off with a waste stream study.This summer, waste on the National Mall will be studied by type and volume and Coke will help formulate best practices on how to address recycling. The Coca-Cola Co. has been a national parks partner since 2007. This may help me make a choice in the coke or pepsi battle?

toxicity and human health #2

"Recognize Toxic Chemicals in Body Care Products"
Tuesday, February 03, 2009
by: Jo Hartley

Summary: "Often the ingredient lists on these "natural" products contain chemicals that are unrecognizable and unfamiliar to most people." This article is about recognizing toxic chemicals in everyday products.

"Almost every synthetic chemical that exists has a Material Safety Data Sheet (MSDS) that contains the facts about the chemical as well as any potential dangers associated with human health." The article also states that "The MSDS lists a summary of the facts for each chemical and summarizes other facts such as hazard identification, first aid instructions, exposure limits, and other names that are associated with the specific chemical." This is very scary to think about because I read ingredients on labels all the time and I have no idea what they are. Most people including myself think nothing of it at the time and proceed to use that product but what are we really putting in our bodies? Is this going to affect our health compared to other generations? Maybe our sophistication in evolution is actually going to harm us we need such advancements in medicine and technology to keep up with the bad things we do to ourselves that other eras of people did not!
