Compare and contrast at least two different ways human activity affects the ecosystem both positively and negatively

Got dis

Explanation:

When humans mass produce items for others to buy, those factories that make that stuff release carbon dioxide into the atmosphere which kills the ozone layer (the ozone layer basically protects everything on this planet from the suns dangerous UV rays). On the other hand humans try to help out the environment for example those cars that people use that use electricity and not fossil fuels as energy for the car and the fossil fuels have the same affect as the factories but the electricity does not release the fumes that the fossil fuel cars do. Hope this answers your question!

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
