Reproduce fast/ evolve
3
Q
Pesticides
A
Weeds becoming resistant to roundup
Organophosphate herbicide
Europe lists it as carcinogen
Current use of roundup much higher than tested safe
4
Q
Antibiotics/ bacteria resistance
A
Bacteria rapidly developing resistance to antibiotics due to
High reproductive rates and lateral gene transfers
5
Q
Emergent disease
With examples
A
A new disease evolves to live in new host Bird flu Swine flu AIDS- from chimps Also viruses mutate into new virus
