This part attempts to provide adequate evidences to explain that environmental problems are human origin and it argues more philosophically by providing the statements of the leading philosophers on the man’s state and responsibilities in the environment, it concludes in order to preserve the environment, changes to be done in social and behavior levels in the entire human system. Modified genes from engineered crop plants are escaping into weeds and other wild varieties. Today GE canola, corn and lesser extent soybean and cotton are contaminating their non-GE counterparts; this has created an economic burden and loss of US agricultural exports. Crops engineered to produce BT (Bacillus thuringiensis) toxins affect the non-targeted insect pests such as monarch butterflies. Hundreds of people exposed to BT spray have shown allergic responses, GM DNA can transfer to organs even into fetus. Commonly agreed solutions are declarations of GMO free zones, it is mandatory to label GM products, handling, marketing and exporting GMOs and encourage the use of non BT products. Similarly, products of Nano technology such as nano silver from antibacterial products, nano TiO2 from faded paints and cosmetics, nano zinc oxide from sunscreen lotions and carbon nano tubes from optics, electronics, car parts contaminate the environment and cause ill health to human such as inflammation in lungs, epithelioid granulomas, fibrosis, pleural mesothelioma and cancer on the tissue lining of the lung or abdomen, however its availability on high concentrations increases the probability of such threat. As most of the chances of availability of nano particles are air and sewage effluents it is recommended to use nano filters and most advanced treatment methods to purify the air and water for nano particles.
