Explanation:
Detailed explanation-1: -The most positive human impact on the environment is the reversal of environmental destruction through remedial actions. These include recycling, conserving water, improving energy efficiency, cordoning off sensitive ecosystems, planting trees, and passing environmental protection laws.
Detailed explanation-2: -How can this process affect other organisms in the water? Oxygen is used up as algae is decomposed, reducing the amount available to other organisms. Algal blooms, often caused by high levels of nitrogen in water lead to low dissolved oxygen levels and the death of many species in these ecosystems.
