genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
