The environment represents the surrounding in which the humans, animals, plants, and every other organism exists and functions. These surroundings are both biotic and abiotic, and they are all connected, and also being dependent on each other. The environment and its well being is crucial for the survival of any living organism, including the humans, so its preservation is a must, and the heavy destruction that is happening to it because of the human activity has to be stopped, other wise there will another mass extinction on the planet, and the humans will probably be part of it.
There are now many small soay sheep in Scotland because the winters are not as brutally cold as they use to be. The climate in Scotland has been warming therefore the sheeps of small stature can easily survive now in Scotland, which was not possible in earlier years.
