Mayflies are sensitive to changes in water quality, so their presence or absence can indicate the health of a water body. High levels of pollution can harm mayfly populations, leading to declines in their numbers. By studying mayflies in a water system, scientists can assess pollution levels and overall ecosystem health.
Pollution can destroy an animal's environment. It can kill plants, trees and even animals themselves. If pollution kills a tree then the animals that were living in that tree have no home. Pollution can also destroy vegetation that animals feed on.
Nobody keeps track of worldwide animal deaths each year. So lets do some estimating. For humans estimates range as high as 40% of the worlds deaths are attributable to non specific forms of pollution. The problem of arriving at a figure is to determine if pollution is directly, indirectly or marginally related to any specific death. Based on this rate, here is an estimate of the incidence of death among people now living in the world with the equivalent pollution related rates is 56.0 million deaths per year (from all causes) with 14 million/yr from some pollution related causes. There are more animals from people and so there is a larger number of animal deaths. animals have to eat the oil and they die from a horrible death so that is why we have to get rid of garbage island
1,200 a year in the U.S. on average. Worldwide figures are not known.
The short answer is yes. The long answer is that isotopes have different numbers of neutrons than other isotopes of the same element, so when expressing the mass of an isotope, you don't take an average; you just add the number of neutrons and the number of protons. However, that number is not entirely accurate since the mass of a proton and a neutron are very slightly different. So, if you want to be very exact, then no, the mass of an isotope is not a whole number, but it is very, very close.
Air pollution from vehicle and snowmobile emissions. Water pollution from vehicles. Noise pollution from vehicles and large numbers of people affects the animals and their health.

Due to having large numbers of heavy scale and small scale industries.Large number of vehicles is also responsible air pollution
The average of the remaining numbers is 38.

To find the average of a list of numbers, add the numbers and divide by the number of numbers in the list.
The average of n numbers = (sum of n numbers) / (count of n numbers).
There are many sets of numbers with an average of 50.Two numbers with an average of 50 is 49 and 51.
yes as all pollution is sucked into the river banks and causes the lower numbers of sea life.
