What Are the Advantages and Disadvantages of Mining?
· Mining gives people a portion of the resources needed for modern civilization, but it can also lead to environmental harm. While some are in favor of mining due to the resources it produces and the jobs it provides in the, some are opposed to mining based on opposition to destructive mining practices and environmental concerns.
Hydropower and the environment
· Hydropower turbines kill and injure some of the fish that pass through the turbine. The Department of Energy has sponsored the research and development of turbines that could reduce fish deaths to lower than 2%, in comparison with fish kills of 5% to 10% for the best existing turbines.
What's the impact of construction on environment?
· Metals, concrete, glass, wood, bricks, asphalt etc are wasted and then disposed off in incinerators and landfills. This results in atmospheric and land pollution, but the transportation used in the process also has a negative impact of construction on environment. Can there be positive impact of construction on environment?
