1.  Solving Real World Problems Chapter 1 Section 2

2. Warm Up  What is the relationship between scientific research the environment and the people living in it (help or hurt) ? Provide examples!

3. Objective  SWBAT evaluate the impact of scientific research on the environment and the advancement of biological technology.

4. How are Biologists working to solve Today’s problems?  Preserving our environment  Improving the food supply  Understanding the Human Genome  Fighting disease

5. Preserving Our Environment  Increasing Human Population  Land for humans v plants and animals  Conservation  Resources http://www.youtube.com/watch?v=lm7WlM-wDHQ

6. Potato Recycling Potato waste Potato water Particles used To produce Methane gas For power plants Mix with Grains to Feed cows Nutrient Rich Water used to Fertilize crops

7. Improving Food Supply  Genetic Engineering  Resistance to herbicides  Crops poisonous to pests  Improved nutrition

8. The Human Genome  A genome is the complete genetic material contained in an individual.  Government-funded and private research teams from several countries completed sequencing of the human genome (2003).  Valuable tool in Medical Research

9. Fighting Disease  AIDS is a fatal disease caused by HIV  New vaccines are being tested that attack two or more parts of the HIV virus at the same time. So that while one part may mutate, it is unlikely that both parts will mutate in the same virus particle.

10.  Cancer is a growth defect in cells, a breakdown of the mechanism that controls cell division.  Great progress is being made in cancer research.

11. Emerging Diseases  Biologists are fighting new diseases not known in the past.  Some of these diseases include West Nile virus, mad cow disease, Ebola.

12. Gene Therapy  The replacement of a defective gene with a normal one.  Researchers believe it is possible to use a virus to transfer a normal copy of a gene into a cell.  Researchers hoped to cure cystic fibrosis using this technique

13. Cloning  Producing a genetically identical copies of a biological entity.  The copied material, which has the same genetic makeup as the original.  Naturally occurring?
