Humanity is regarded as a biological entity by the environment as directly dependent on the natural world. Many vital resources on earth have to be exhausted if there is already deteriorating atmospheric chemistry and dangerous growth of human populations. Natural environments irreversibly destroy the foundation of a safe climate. All living things that live on this earth come under the environment. Whether they live on land or water they are part of the environment. The environment also includes air, water, sunlight, plants, animals, etc. Moreover, the earth is considered the only planet in the universe that supports life. The environment can be understood as a blanket that keeps life on the planet safe and sound.
If present growth trends in world population, industrialization, pollution, food problems and resource depletion continue unchanged, the limits to growth on this planet will be reached within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity.
