A recent study published in the journal Nature shows that genetically modified crops have no better survival skills than conventional varieties and do not crowd out natural species. The 10-year study, conducted in England, looked at soybeans, oilseed rape, potatoes, corn and sugar beets that had been genetically engineered to resist insects or herbicides. They were planted in 12 separate habitats, ranging from woodlands to coastal areas. The results showed that neither the conventional nor the modified plants increased in numbers beyond their first plantings. The modified plants didn t last significantly longer than their conventional counterparts.
Researchers propose using a belt system to collect and dry manure.
Then it would be put through gasification, the process of burning a substance in a low-oxygen environment to convert complex organic compounds to gases. The process would yield methane, carbon monoxide and hydrogen, which would then be collected and used to make fuel-grade ethanol.
