1. Around 1900 the first dams were built on the Muskegon river, and this immediately cause a problem in the ecosystem by being a blockade for the movement of the water species, as well as causing higher mortality by killing them in the turbines.
2. By 1950 more dams were built, and the there were even more blockades on the way of the water species, so their movement was restricted even more, the mortality rates skyrocketed because of the disposing of the oxygen, temperature change, river flows changing etc.
3. Even though the scientists miss information from the period before the dams were built, since the information have started to be gathered it has been very obvious that the main factor for ruining the ecosystems on the Muskegon river are the dams by causing all sorts of changes in the water.
Answer:
(hope this helps can I pls have brainlist. (crown) ☺️)
Explanation:
Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heatwaves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal livelihoods and communities.
Answer:
* What is meant by coastal management?
coastal management is a defence technique to prevent or lower the occurrence of flooding and erosion, and ways to stop erosion from claiming lands. Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change.
* Why is coastal management important?
The reason for coastal management is obvious, which is to protect homes and businesses from being damaged and even destroyed by coastal erosion or flooding. Failure to do so can have severe economic and social effects, especially along coastlines which are used for tourism and industry.
Answer:
Rain washes pollutants off streets and into storm drains, which drain into Puget Sound.
Explanation:
"Puget Sound" is a Pacific Ocean inlet that is located in Washington's northwestern coast. It is said that the name "Puget Sound" was given by George Vancouver in<em> 1792,</em> in honor of a lieutenant, Peter Puget, who was very helpful in guiding him through his expedition.
Puget Sound is home to many marine species, such as salmon, Pacific rods, harbor seals, Pacific herring and the like. However, some of these, like the <em>"Olympia oysters,"</em> have been depleted because of human activities. The recession of many species in this area has been increasing over time. It is said that the inlet was contaminated with radioactive water in 1978, when a submarine accidentally released the radioactive water into Puget Sounds.
Another reason for its buildup of pollution is through the <u>"storm water's run-off." </u>When a storm comes, it hits infrastructure's roofs and other surfaces or pollutants. The debris are carried into the drains by rain and are then drained further into Puget Sound.
The toxic chemicals that are carried primarily comes from the roofing materials or human's everyday products.
