The environment is everything that surrounds one or another living organism. It is determined by two groups of factors: factors that are not associated with the life of other organisms (the so-called abiotic), and factors associated with the life of other organisms.
To abiotic factors like light, humidity, temperature, landscape and other natural conditions. Depending on the amount of natural settings, for example, about the inhabitants of the desert, steppe, or taiga.
Plants and lower animals in the environment are passive, whereas the higher animals choose their environment and even create it.
There is habitat and people. It is called anthropogenic, that is modified as a result of human activity. Unfortunately, very often our habitat displaces habitat neighbors on the planet of plants and animals.
