Answer: Water pollution can have disastrous effects on the environment.
Explanation:
- Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe. The fish can suffocate and not have enough air.
- Pollution affects the entire food chain. Small fishes absorb pollutants, such as chemicals, into their bodies. Bigger fishes eat the smaller fishes and get the pollutants as well. Birds or other animals may eat the bigger fishes and be harmed by the pollutants. One example of this was the use of the insecticide (bug killer) DDT, which is when birds of prey ate fishes that were infected with it, they would lay eggs with thin shells. The population of birds of prey began to drop until DDT was banished.
- Sewage causes major problems in rivers. Bacteria in the water will use oxygen to break down the sewage. If there is too much sewage, the bacteria could use up oxygen until there won't be enough left for the fish.
- Water pollution from major events like acid rain or oil spills can completely destroy marine habitats.
- One of the most important commodities for life on planet Earth is clean water. For over 1 billion people on the planet, clean water is nearly impossible to get. Dirty, polluted water can make them sick enough to die.
Geothermal activity visible on the surface,acute to extreme seismographic readings. typically on the borders of tectonics plates. (Ring of fire)
So with the first number in each set, look on the x axis or the horizontal line for the number. For example, 2 1/2 on the horizontal line or x axis is on the right side, next to the two and the x. The second number is on the vertical side, and the same thing. In this case, -1 1/2 would be on the bottom in between the -1 and the arrow.
Now find the place where the two intersect on the coordinate plane, and put a dot there to mark the coordinate.
"Reading Like a Historian" is a strategy developed by Stanford University in which students approach history by reading primary source documents. Anchored by these texts, students explore different perspectives of historical events and develop opinions based on their reading. I tried my best
