drastically changing the environment with all the needs he has. Humans cut down entire forests in the course of a month. Then we build buildings in its place making it impossible for anything to grow there. Those trees were a crucial part to the ecosystem and environment‚ which are now changed forever. We also drive cars‚ which emit exhaust‚ which in turn hurts our ozone layer and heats up the Earth. Once the ozone layer is damaged the ice caps melt a little and now the entire environment is changed

The long-lived and healthy ecosystems are prime examples of sustainable biological systems with chemical cycles that redistribute water‚ oxygen‚ nitrogen and carbon through the world’s living and non-living systems‚ and have sustained life for millions of years. As the earth’s human population has increased these natural ecosystems have declined and changes in the balance of natural

In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction

The argument for diverting water for permitting the flow of water to natural areas would allow the recharge of groundwater supplies which is important in sustaining a supply of water for the human use and ecosystems. Conservation of water supplies is important for future generations so that they will have enough available water for consumption to urban areas and agricultural areas.
