Which of the following are example of the harmful effects of excessive irrigation? a\. Excessive irrigation contributes to the depletion of groundwater and surface water supplies. b\. Irrigation can cause waterlogging, in which water accumulates underground and gradually raises the water table. c\. Loss of soil fertility through depletion of plant nutrients in topsoil. d\. Both A and B 9.The technology for genetically modified crops and foods is fast growing and there is no possibility of stopping. While it benefits food security issues, it also poses known and unknown threats. Below is the list of disadvantages of trade-offs GMO EXCEPT for one. a\. More resistant to insects, disease, frost, and drought. b\. More pesticide-resistant insects and herbicide-resistant weeds. c\. Could disrupt the seed market. d\. Harmful toxins and new allergens in food 10.There are a few controversies over genetically engineered foods, some even coined it as "Frankenfood". The term Frankenfood comes from the novel Frankenstein by Mary Shelley, relating genetically modified foods to the monster that Dr. Frankenstein created. In order for Frankenfood to be created, the DNA of the food needs to be manipulated. Which of the following statements below explains the fear of critics of GMOs? a\. Warn that we know too little about the long-term potential harm to human health and ecosystems from the widespread use of such crops. b\. Warn that GM organisms released into the environment may cause some unintended harmful genetic and ecological effects. c\. Genes in plant pollen from GM crops can spread among nonengineered species. The new strains can then form hybrids with wild crop varieties, which could reduce the natural genetic biodiversity of wild strains. d\. All of the above 11.Which of the following is NOT an environmental issue brought about by the poor management of our water resources? a\. falling water tables b\. swelling of lakes c\. decreasing river flows d\. disappearing wetlands 12The three major global uses of fresh water are \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ a\. manufacturing goods, wastewater disposal, and irrigation b\. drinking, bathing, and growing crops c\. drinking, manufacturing goods, and generating power d\. residential, agricultural, and industrial uses 13.Ninety-seven percent of the world's water resources are found in \_\_\_\_\_\_\_. a\. freshwater b\. ice caps and glaciers c\. saltwater d\. Groundwater 14.Polluted groundwater is difficult to clean up because \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. a\. groundwater is deep in the ground and dispersed through large areas of rock. b\. pollutants cling to the materials that make up the aquifer and contaminate the clean water. c. the recycling process of groundwater can take hundreds or thousands of years. d\. All of the above 15.Over pumping aquifers has several harmful effects\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. a\. limits future food production b\. increases the gap between the rich and the poor c\. allows land to collapse due to Subsidence and sinkholes d\. all of the above 16.Vapor-compression evaporation, Thermal distillation, membrane distillation, and Reverse Osmosis are examples of? a\.
