Using America as an example Total waste reduction between 1960 and 2013 almost tripled and personal (per person) waste disposal doubled. .So ... no it does not seem that humans have become less wasteful.
he made government more efficient and less wasteful
Humans have lower genetic variation compared to other species due to the bottleneck effect experienced in human evolution. This is because human populations are relatively small and have undergone significant reductions in genetic diversity.

Smaller natural habitat, more human encroachment, and less food are the three main causes for the decline of the frog species.
I presume you mean, how does a new species form?... A group of one species get seperated from another, and circumstance change. shall we say... the tempertature rises? this one group (in a high temperature) will have an advantage if they have less fur, for they will not be as hot, therefore they become 'desirable mates' and through many generations the species has less fur, becoming an altogether seperate species than it started
You may be trying to find out how recklessly wasteful human civilization used to be prior to current environmental awareness, but really, there has been no reduction in human wastefulness, although some efforts have been made by some people in some locations. The continuing increase in the human population of the world (now at approximately seven billion) means that even if some people are less wasteful, the total amount of waste is increasing. Also note that there really was no time in human history when we did not make use of renewable resources such as sunlight. That has always played a large role in human existence. We grow crops using sunlight, as we have since earliest historical times.
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
the dire wolf went extinct because there started to be less and less of them. everyday a dire wolf had got killed by a human, another animal, or from not eating
Some fish species die of old age in less than 1 human year and others would be still youngsters at 100 years.
Probably because they are large and tough.Larger animals tend to be higher up in the food chain and are less likely to be eaten when born. A mouse needs to have dozens of offspring a year to insure that one of then will get to continue the species. A human or and elephant need only have a few offspring in a lifetime to continue the species.
