The Toxics in Fish Implementation Strategy is a recovery plan that will be used to guide funding and activities to reduce the impacts of toxics contaminants on marine fish and the humans that consume them. The plan is scheduled to be completed in Following a generally warmer and drier winter and then a cold spell in February, Puget Sound waters are cold for anchovies. The productive season is in full swing with algal blooms spotted in South Sound, Kitsap Peninsula, and Quartermaster Harbor.

Jellyfish are abundant in some inlets, and Noctiluca stains the water orange in Hood Canal. We collect monthly data to keep you informed about the conditions around Puget Sound.

Come into the lab and see how we assure the highest data quality from our field instruments! Understanding the social networks and family bonds of Puget Sound's southern resident orcas may be critical to keeping the endangered whales from extinction. A healthy population is about more than numbers, scientists say. It's about connections. Bills in the state legislature target oil spill threats to Puget Sound and its endangered killer whales.

An EPA-funded study of oil spill risks in Puget Sound forms the basis of new legislation to regulate vessel traffic in the region. We break down some of the numbers from the study and look at where the risks may be greatest. In Washington State, the pinto abalone Haliotis kamtschatkana has declined by 97 percent since and is unlikely to recover without intervention. A captive rearing and restocking pilot study shows promise for saving wild populations from local extinction. The sunflower sea star Pycnopodia helianthoides is highly susceptible to sea star wasting disease. The authors of a paper published in Science Advances document the rapid, widespread decline of sunflower stars and discuss the ecological implications of losing this important subtidal predator species.

This three-part series explores opportunities and challenges of using medical interventions to save Puget Sound's southern resident orcas from extinction. Part 1 looks at how scientists might treat endangered southern resident orcas that face starvation and risks of disease; Part 2 considers how veterinarians have intervened with other animals in the wild, and how this might apply to orcas in Puget Sound; and Part 3 explores a federally approved vaccination program designed to ward of a deadly virus among endangered Hawaiian monk seals.

Although fall and winter were warm, February brought cold snowy weather and low river flows. Despite colder air temperatures, the productive season has already started in Hood Canal and Holmes Harbor. Puget Sound waters were warmer than expected through January, and the warmest waters were in Hood Canal, possibly creating a thermal refuge for cold-sensitive species such as anchovies. We saw lots of sea lions feasting on anchovies in Case Inlet, and we may have captured some herring spawning activity. Unusual for mid-winter, we saw jellyfish patches in Eld and Budd inlets.

See the new publication about ocean acidification featuring twenty-five years of our marine monitoring data! Now a network of scientists and advocates is working to restore them to their historical and cultural prominence. Incinerating trash gets rid of it, but it can release dangerous heavy metal s and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution.

Reducing Pollution Around the world, people and governments are making efforts to combat pollution.

Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused. Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage.

Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusiness es are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fine d for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted.

International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by countries. Still, many gains have been made. In , the Cuyahoga River, in the U. The fire helped spur the Clean Water Act of This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted.

As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night.

Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere. Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports.

Library and Information Science Encyclopedia

Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food. How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution. Acids can corrode some natural materials. Acids have pH levels lower than 7. Acid rain can be manmade or occur naturally. When released through a small opening, the liquid becomes a spray or foam.


Also called cyanobacteria and in freshwater habitats pond scum. Carbon dioxide is also the byproduct of burning fossil fuels. It can be toxic to humans. Some CFCs have destructive effects on the ozone layer.

Some plastics we can reuse or recycle—and many play important roles in areas like medicine and public safety—but other items, such as straws, are designed for only one use. It often breaks down into smaller and smaller particles, called microplastics, which can be ingested by both animals and people. Use these classroom resources to teach about ocean plastics and check back for more coming later this year!

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water. Help your students understand the impact humans have on the physical environment with these classroom resources. In the United Nations General Assembly adopted 17 sustainable development goals designed to transform our world by The sixth goal is to ensure the availability and sustainable management of water and sanitation for all.

According to the United Nations, one in three people live without sanitation.

A lack of sanitation and sanitary waste management systems can reduce a community's access to clean water, and lack of access to clean water can allow diseases to run rampant, sometimes creating epidemics of water-borne infectious agents. Learning about how freshwater systems work in the wilderness, rural communities, and urban centers can help us better understand the challenges of providing clean water and sanitation to people around the world.
