Lead Poisoning Hinders the Recovery of Bald Eagles

by Makya Rodriguez, age 17

The mighty bald eagle is facing some tough times. In recent years, the population of our national bird has decreased by almost 4%, and lead poisoning is usually the reason.

A new nationwide study has found that up to 33% of examined dead bald eagles contained serious levels of lead poisoning. This clinical poisoning is mainly transmitted from an eagle’s prey such as fish or small animals. After consuming such prey, the eagles’ stomach acids break down neurotoxin and release lead into the bird’s bloodstream. The lead then travels to soft tissues around the body and eventually accumulates within the bird’s bones leading to the death of these beautiful animals.

In colder seasons eagles tend to go from natural hunters to scavengers. Scientists have found that eagles are more likely to get poisoned during the colder months when they depend more on the tainted remains of dead prey. [read more]

When Exploring Dane County’s Sugar River, Keep and Eye Out for Invasive Species

by Dayanara Flores Gonzalez, age 14

The Sugar River, also known as The Upper Sugar River Watershed, is located in Dane County and flows all the way down to the Rock River.

The Upper Sugar River Watershed Association works to protect the river from invasive species that can harm or push out native species and damage the ecosystem. Many rare and endangered native plants found in the river and its nearby wetlands are threatened. Most wetland animals depend on these native plants for food and shelter.

Some native species can disappear if a watershed loses its healthy wetlands. Recreational uses of wetlands include trapping, fishing, bird watching, and nature study. Healthy wetlands can help with keeping the water clean and safe for wildlife. Healthy wetlands also help control and prevent floods. [read more]

Stopping Climate Change Begins With Renewable Energy

by Sarah Thomson, age 13

Imagine a future where storms, droughts, and floods are much more destructive and much more common than they are today. In this foreseeable future, the world's ecosystems have altered significantly with polar bears and many other animals extinct and others migrating across the globe. Diseases exist in areas they had never been before. Many experts believe this future could become a reality if humans do not slow down the current global warming problem.

Global warming is caused by humans burning fossil fuels like coal and oil. Burning these fuels releases carbon dioxide into the atmosphere. Carbon dioxide and other gases – known as “greenhouse gases” – trap some of the sun's heat in Earth's atmosphere. This process is called the “greenhouse effect” because it acts as a greenhouse in the manner in which it retains heat. This is what keeps Earth at a livable temperature. However, as more greenhouse gases are released into the atmosphere, more heat is trapped, warming the Earth more than what naturally occurs. As humans burn fossil fuels to meet their energy demands, the Earth faces serious problems.

Global warming causes huge amounts of climate change around the globe. Glaciers and ice sheets are melting at the poles, raising sea levels. This is creating problems for coastal settlements. Natural disasters like floods, droughts, and hurricanes will become more common and more severe. The changes in climate will also affect animals and ecosystems. Some animal species may become extinct while others move across the globe to new areas where they can survive. This migration could cause the spread of diseases. For instance, mosquitoes will be able to carry diseases such as malaria and the Zika virus to many more areas. Global warming isn't a simple matter of a slightly warmer planet: it is causing a series of serious problems that will only get worse unless people do something about it. [read more]

What You Have to Know About GMO's

by Sanaai Brazil-Broach , age 12

Are genetically modified foods safe to consume?

Over the last two decades, food that consumers have eaten contains genes from other plants that make them either grow faster, taste better or stay fresher for a longer period of time. Foods that have been altered this way are called “genetically modified foods.”

Some reasons companies may modify food is because they want it to look more appealing, or they are trying to give people the vitamins that their bodies need. Each year, for example, around half of a million children go blind, and one or two million children die from the lack of vitamin A. So scientists have developed vitamin A in rice and put it in other foods to help solve this problem. [read more]

Lesser Long-Nosed Bat Escapes Endangered Species List

by Abigail Comerford, age 14

The lesser long-nosed bat is no longer endangered thanks to conservation made possible by scientists and volunteers. It is the first U.S. bat to escape endangerment. The bats' recovery is thanks to cooperation between the United States and Mexico.

Amy Lueders, the southwest regional director for the U.S. Fish and Wildlife Service, claims that science shows that threats to the species have decreased to the point of the bats' recovery.

She also states, “the Service is proud of our strong, decades-long partnership with very diverse stakeholders on behalf of the lesser long-nosed bat. Without partnerships and collaborations such as these, successful recovery would not be possible.” [read more]

How Climate Change Affects the Poles

by Felix Berkelman, age 14

Although one might think the Arctic and Antarctic seem basically the same climate wise, they are actually noticeably different. Likewise, they are also affected differently by climate change. Both areas have melting ice, however the two poles have it for a different reason.

The main reason for the difference in climate is the positioning of land around the poles. The North Pole consists of an ocean surrounded by land, while the South Pole is the opposite, a land mass surrounded by ocean. Although this detail may seem meaningless, it actually has a drastic effect on the temperature of the poles.

The Southern Ocean is the only place where there is a ring of ocean, unbroken by land, surrounding the earth. This causes ocean currents to circle Antarctica in what is known as the Circumpolar Current. This current is one of the strongest in the world, and causes massive waves in the Southern Ocean. These waves make countries like South Africa and New Zealand ideal for surfing, but make reaching Antarctica a difficult ordeal. The Circumpolar Current also insulates the continent from warmer air farther north, making it much colder than the Arctic. [read more]

What are snakeheads? A snakehead is an invasive fish with a cylindrical shape and sharp teeth. An invasive species is a non-native organism that can harm an ecosystem. Snakeheads are separated into two genera: parachanna and channa. They are native to various parts of Africa and Asia; however, in 2002, the northern snakehead was caught in a Maryland pond. This immediately gained national attention and indicated that snakeheads were reproducing around the Maryland-Virginia area as well as in other states such as Wisconsin, Maine, Florida, as well as along the east and west coasts.
