One concept unites Biosphere 2's diverse activities: the observation that human activity has been fundamentally changing the nature of the Earth as a system over the last several decades, and that these systemic changes are accelerating. Increases in CO2, changes in methods of managing land and aquatic resources, changes in the nitrogen cycle, and upward trends in global temperatures all remind us that when we start to think on a planetary scale about these changes, we need to understand, first, how the Earth works without human impact and then how this human impact modifies the natural variability of the Earth. Over the next century, how we understand the difference between the two carries enormous implications for both human livelihood and environmental integrity.
The terrestrial research ship
Columbia's management of Biosphere 2 as a research station, in some ways, represents an extension of methods that Columbia ecologists have long practiced in other fields. Earth scientists from Lamont-Doherty have done a great deal of work on oceangoing vessels; the enormous greenhouse known as Biosphere 2 is the land-based equivalent of a research ship, an advanced field station with analytic facilities that allow the scientific staff to comprehend the detailed features of an entire region. Terrestrial ecologists recognize the amazing diversity of the American Southwest, going from subalpine forests at the top of the Catalina Mountains--terrain with structural and functional similarities to something one would find in Canada--through the deserts of Mexico to the Sea of Cortez. These several hundred miles of varied terrain present extreme ecologic diversity, and Biosphere 2 replicates that diversity by including six different environments (tropical rain forest, savanna, thornscrub, marsh, desert, and ocean) in its different segments or biomes. Studying each biome as a separate system (each can be cordoned off with removable plastic curtains) or studying the Biosphere enclosure as a whole, researchers can conduct controlled experiments on a full- ecosystem level, placing each individual measurement--atmospheric water, CO2, plant growth, or any other variable--in its natural context.

chemical changes in water or the air, temperature change (climate change) these are just some.
they can change it alot of ways if a person cuts down a tree a birds home wil be lost that is one way they could liture
The Earth is dynamic because it continues to grow and change. Geologically and astronomically, the Earth has a history covering billions of years. The planet has changed from a gassy ball of rock to a beautiful ocean covered jewel, abundant with life. The Earth will continue to change over the coming millenia, based on astronomical theories and the potential impact of humanity.
If we stop recycling, the amount of waste going to landfills will increase significantly. This can lead to a depletion of natural resources, pollution, and harm to ecosystems. Additionally, recycling helps to conserve energy and reduce greenhouse gas emissions, so stopping recycling efforts would have negative consequences for the environment and contribute to climate change.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
The two major global changes affecting the biosphere today are the ozone layer high in the atmosphere and the global climate system. Hope this helps! (:It's the global warming and the climate change. The biosphere is the global sum of all ecosystems
Population ecologists study the size, density, and structure of populations and how they change over time. ... Ecologists working at the biosphere level may study global patterns—for example, climate or species distribution—interactions among ecosystems, and phenomena that affect the entire globe, such as climate change.
