Human-induced changes in the environment will often result in increased numbers of a species. For example, piles of scrap building material make excellent sites where rodents can nest.
Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary ...
