Natural selection is a direct product of the environment.
A couple of simple examples are:
In a cold environment the only plants and animals that will survive will be cold tolerant plants and animals.
In a forest of Bears the only animals to survive will be animals that are faster or bigger than Bears.
A sudden change in environmental conditions, such as an Ice Age, will see whole populations of some species disappear while only remnants of some species will survive.
Those remnants will display either cold tolerance or the ability to withstand the cold by other means ie: clothing or fire.

Natural selection affects populations of organisms. More specifically, it affects the way organisms interact with one another and with their environment. And through this, it indirectly affects the environment.
When organisms adapt to a changing environment, genetic variation (a part of natural selection) can lead to diversity.
Yes environmental factors do influence natural selection.
Yes, and no. Natural selection usually refers to a situation wherein alleles or organisms compete against eachother without external guidance, under the influence of mindless environmental factors. In horse breeding, the principle is almost exactly the same, but the factors influencing the differential reproductive success of alleles include the intelligent decisions of humans.
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.
Population Size, Mate Selection, Gene flow between Populations, Mutations and Natural Selection Hope that helps
Higher the genetic variation, better luck to deal with wider range of environmental factors hence better luck to pass the sieve of natural selection. ALSO Organisms (plants, animals, bacteria, etc) that have more traits that are favorable in the environment will live longer and have more opportunities to reproduce and create offspring that share their favorable traits. Organisms with traits unsuitable for the environment will die sooner, and will produce fewer or no offspring. If given enough time in a stable environment, the population will eventually reflect the genes best suited for it, assuming pure natural selection.
Natural selection is something that happens over time and is somewhat dependent on the conditions of climate and environmental changes. There are times when natural selection can favor different phenotypes, if and when the culture starts to seek out others with certain traits and characteristics to breed.
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.

Mutation and natural selection.
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
