1.       Exploratory PFC is an acronym that stands for proper functioning condition. This is a long-standing rapid assessment the BLM uses to evaluate overall conditions and impairment of streams and streamside vegetation. Land managers are increasingly resorting to two natural ways to rehabilitate damaged riparian regions and improve stream habitats: grazing management and beaver management. In recent decades, BLM land managers and ranchers who lease BLM lands for grazing in each watershed have changed their grazing techniques. 2. Diagnostic BLM management aims to transition streams that have been degraded by stressors like droughts, wildfires, and previous grazing practices from a nonfunctional status to a normal functioning status, to ensure that they remain that way. 3. Cause and Effect It turns out that beavers, particularly in the parched Great Basin, are a significant amplifier of the return of streamside plant life. By rewetting floodplains and...

  After reading and analyzing Chapter One, it is clear that the focus of environmental policy has been on managing natural resources and preserving public health since colonial times and continues to be so today. Scientific breakthroughs, technological developments, and changes in public attitudes toward natural resources are significantly responsible for significant changes in US environmental legislation. What precisely are environmental policies? Environmental policy relates to public-sector legislation, regulations, and incentives. Almost as soon as Europeans landed in the Americas, they attempted to govern the use of natural resources. The environment they found had been extensively altered by native people. As a result, settlers faced a number of environmental issues, such as safeguarding cattle from predators, managing trees, and avoiding overhunting. The simple duty of feeding their family and heating their houses made environmental management one of the most serious enviro...

  Current Events in Plastic Pollution 1. Exploratory Basic facts and knowledge found in my article were that the extensive usage of plastics outside of the military did not begin until after World War II. It is believed that 90.5% of all plastic garbage produced has been recycled. 79% of plastic trash has ended up in landfills or as litter. While the remaining 12% has been burned. That being said, plastic debris has been discovered in all major ocean basins, with an estimated 4 to 12 million metric tons of plastic garbage produced on land entering the marine environment in 2010. Plastic manufacturing has grown faster than any other industrial material during the previous 65 years. 2. Diagnostic The same properties that make plastics so useful in a variety of industries- durability and resistance to degradation- make these materials difficult or impossible for nature to ingest. The great majority of monomers used to produce plastics, such as ethylene and propylene, are now g...

 What Is Microplastics? After in-depth reading, reviewing resources, and taking notes, I have learned that fresh water is one of the most important resources and one of the most abused. Water has faced continuous threats of pollution and because of it types of pollution have evolved and expanded over time. A little background information about plastic is that before 1950, plastic was barely a part of American life. Modern plastic came to be more produced and used during World War two. It wasn’t until the early 60s that global plastic production increased by 40%, and by 1979 more plastic was being produced than steel. And in 2014 100 billion plastic bags were used in the USA. Just imagine how much plastic we use now in 2023. What is microplastic? Microplastics are plastic particles of fibers smaller than five millimeters in size and are one of the many environmentally detrimental outcomes of modern society's widespread use of plastics. Plastics are made of polymers, which are long, ...
