For the most part‚ the general population can safely ignore the amounts that are ingested‚ except if they live near hazardous waste sites‚ mines‚ or if crops are grown in contaminated soil or watered with contaminated water.”- (Stephanie Pappas).

The fungus grows where there is high nitrogen content or where there is a lot of bat droppings and bird manure. H. capsulatum spores can become airborne where contaminated soil is disturbed.

Most bio-weapons can spread through the air‚ with explosives‚ food and water‚ or absorbed through the skin. Some of the weapons have been eradicated while others still exist‚ but are dormant.

Remove and replace unsuitable soils. Attempt to modify the existing ground. Relatively few options are available in choosing the ground materials and site conditions that must be accounted for in the design of highway projects. The project must be constructed under the conditions that

Mountaintop removal is a procedure in mining that involves using high power explosives for the removal of the top of a mountain to expose the valuable coal seams below. It differs from traditional underground mining in the sense that it is not underground. This technique of mining is safer for the workers because it results in a smaller

While fracking has aided in the plumpting of gas prices across the United States‚ it unfortunately causes serious health and environmental issues.
