Write an argumentative report (4-5 paragraphs long) that describes the impact humans have on the environment. Assume your audience is the general public, and your goal is to convince them to make positive changes. Be sure to also research and include details of what actions humans can take to affect positive change for the environment. Support your argument and suggestions for change with evidence from the Internet sources you have read and viewed. You do not need to use all the sources, only the ones that most effectively and credibly support your position and your calls for change.
Answers
Answer:
Explanation:
Humans have had a significant impact on the environment in recent times, and it is essential that we take immediate action to make positive changes to protect our planet. The burning of fossil fuels, deforestation, and the overuse of natural resources have led to increased carbon emissions, air and water pollution, and the destruction of habitats for wildlife. Climate change, caused by human activities, is causing sea levels to rise, extreme weather events to occur more frequently, and is affecting the biodiversity of our planet.
One of the most significant actions humans can take to affect positive change for the environment is to reduce our carbon footprint. This can be achieved by using renewable energy sources, such as solar and wind power, instead of fossil fuels. Additionally, individuals can reduce their carbon footprint by using public transportation, carpooling, or biking instead of driving, and by using energy-efficient appliances and light bulbs. According to the United Nations Framework Convention on Climate Change, if we act now, we can still limit the global temperature increase to 1.5°C, thus avoiding the worst consequences of climate change.
Another way humans can make a positive impact on the environment is by reducing our consumption of meat and dairy. Agriculture is one of the leading causes of deforestation and water pollution. According to the World Wildlife Fund, if we all reduce our meat consumption by 50%, we could prevent the extinction of several species, increase food security, and reduce greenhouse gas emissions.
Lastly, humans can make a positive impact by supporting companies that prioritize the environment and sustainability. Consumers have the power to vote with their dollars and support environmentally friendly products and companies. They can also advocate for more environmentally friendly policies and regulations, and support conservation efforts such as reforestation and habitat restoration.
In conclusion, humans have had a significant impact on the environment, and it is essential that we take immediate action to make positive changes to protect our planet. By reducing our carbon footprint, reducing our consumption of meat and dairy, and supporting environmentally friendly companies and policies, we can make a positive impact on the environment. It's time for us to take responsibility for our actions and make the necessary changes to protect our planet for future generations.

Using the terms solar radiation and terrestrial radiation, explain the heating of the earth by the
sun.
Answers
Solar power is referred to as solar radiation. The amount of solar energy that reaches the earth is referred to as insolation. The radiation that the planet emits is known as terrestrial radiation.
How does the earth's atmosphere maintain its temperature?A tiny amount of radiation from the Earth's surface and the warmed upper atmosphere both radiate into space. The majority of the longwave radiation produced warms the lower atmosphere, which then warms the surface of our planet.
Does terrestrial radiation heat the atmosphere effectively?Therefore, long wave terrestrial radiation is primarily responsible for warming the atmosphere. The majority of the energy that reaches the earth's surface is in short wavelengths. Incoming solar radiation, often known as insolation, is the name for the energy that the earth receives from the sun.

Extra-large breakers are crashing into the surf. How will this affect the undertow? Make a prediction
Answers
Answer:
This will make the undertow return to the sea with greater intensity and violence.
Explanation:
Undertow is the movement of the wave in contrast to the sea, that is, it is the movement of the waves on themselves, which makes the sea very agitated, especially when these waves return to the sea with a lot of violence and force. Although this violence and force can be caused by the wind, extra-large breakers can also cause this effect, because the impact of the waves on the breakers, pushes the waves into the sea with more force, making them more violent and intense.
How do the layers of the atmosphere help to understand better the dynamics of the atmosphere and its relationship to the hydrosphere and lithosphere?
Answers
There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.
The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.
The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

How would you explain the key concepts for the CWA in less than two minutes?
Answers
Answer:
Explanation:
vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.
Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.
Navigable Waters of the United States For the purposes of the Clean Water Act, the term "navigable waters" includes:
all waters used in commerce, including groundwater;
all interstate waters including wetlands, mudflats, and sand-flats; and
all other waters such as lakes, rivers, streams, wetlands and sloughs.
EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters." The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect. In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.
Additional executive orders were issued 2015 in 2019. Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.
Could the requirement for one or more NPDES Discharge Permit apply to my campus?
If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.
Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.
Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.
What do I have to do related to NPDES Discharge Permits?
Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.
French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

Pelicans have a unique set of adaptations that allow them to spot fish from above the water's surface. Pelicans have large eyes that are well-suited to detecting movement, which is essential for spotting fish in the water. They also have the ability to adjust the lenses in their eyes to focus on objects both in the air and underwater
.Their keen eyesight and keen sense of hearing make them excellent hunters, and they are known for their ability to spot fish even in murky water.
Once a pelican spots a fish, it will fold its wings and dive headfirst into the water to catch it. Pelicans can hold their breath for up to a minute while they dive underwater to catch fish, and they can swallow their prey whole.
