Solving Real World Problems
Chapter 1 Section 2
Warm Up
What is the relationship between scientific research the environment and the people living in it (help or hurt) ? Provide examples!
Objective
SWBAT evaluate the impact of scientific research on the environment and the advancement of biological technology.
How are Biologists working to solve Today’s problems?
Preserving our environment
Improving the food supply
Understanding the Human Genome
Fighting disease
Preserving Our Environment
Increasing Human Population Land for humans v plants and animals Conservation Resources

Potato Recycling
Potato

Mix withGrains to Feed cows Nutrient Rich
Water used to Fertilize crops
Improving Food Supply
Genetic Engineering Resistance to herbicides Crops poisonous to pests Improved nutrition
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
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.
Cancer is a growth defect in cells, a breakdown of the mechanism that controls cell division.
Great progress is being made in cancer research.
Emerging Diseases
Biologists are fighting new diseases not known in the past.
Some of these diseases include West Nile virus, mad cow disease, Ebola.
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
Cloning
Producing a genetically identical copies of a biological entity.
The copied material, which has the same genetic makeup as the original.
Naturally occurring?
